The purpose of the research is to investigate Matrix 2T Detachable
Coils ® (MDC) and Guglielmi Detachable Coils ® (GDC)
for the treatment of aneurysms in the brain. GDC and Matrix 2T
coils are medical devices that are approved in the United States
by the Food and Drug Administration (FDA). An aneurysm is a bulging
or ballooning out of a blood vessel caused by a weakness in the
vessel's wall. An aneurysm that is located in a blood vessel
in the brain is called an intracranial aneurysm. If an intracranial
aneurysm is not treated, it can grow bigger, putting pressure
on the brain and causing headaches or other symptoms. As it grows,
it can also become so weak that it bursts, causing a stroke.
Aneurysms
can be treated by using small metal coils. The coils are placed
into the aneurysm to block it off from the blood vessel. Over
time, the coils help tissue grow that fills the aneurysm and
stops the flow of blood into the aneurysm. Both devices being
evaluated in the study, GDC ® and Matrix 2T coils, are similarly
designed to treat an aneurysm.
Matrix 2T coils are small metal coils coated with a material
that helps the body grow the tissue mass that fills the aneurysm.
GDC coils have no coating. The study will collect information
and evaluate treatments using GDC and Matrix 2T coils. The
MAPS Trial is the first study to evaluate these two treatments.
The study may also help the medical community understand endpoints
related to these treatments.
If you meet certain requirements, you may be eligible to participate:
The patient is between 18 and 80 years of age
(inclusive).
The patient has a documented untreated intracranial
saccular aneurysm 4-20 mm diameter angiographic lumen,
ruptured or unruptured, suitable for embolization with coils.
Both GDC ® Coils and Matrix 2T® Coils
(Every attempt should be made to treat with as much randomized
coil type as possible to achieve optimal occlusion) are treatment
options (all shapes allowed with exception of GDC VortX Coil).
Target aneurysm can be adequately coiled at
index procedure (NO staged coiling procedures). If a Neuroform
stent is to be placed during a separate preliminary procedure,
then screening and enrollment for the coiling procedure must
take place after the stenting procedure is completed.
Target aneurysm morphology allows for adequate
retention of coils within the aneurysmal sac without occlusion
of the parent artery, as determined by the treating physician.
Patient (or patient's legally-authorized representative
for centers in the United States) has provided written informed
consent.
Patient is willing and able to comply with protocol
follow-up requirements.
Enrollment is ongoing. For additional information, contact Grant

The NeuroformT Microdelivery Stent, a Humanitarian Use Device,
may be of use in treating wide neck, intracranial aneurysms.
An intracranial aneurysm is a bubble or sac on a blood vessel
in the brain that can become larger over time. Aneurysms have
thin, weak walls and can burst or rupture, causing bleeding into
and around the brain. An intracranial aneurysm rupture can cause
brain injury and death.
A Humanitarian Use Device is a device
used to diagnose or treat a disease or condition that affects
fewer than 4,000 individuals in the United States per year
and for which no comparable device is available. The United States
Food and Drug Administration encourages treatment for rare
conditions, so it does not require as thorough or extensive testing
to demonstrate safety and effectiveness as devices intended
to treat more common conditions. The FDA permits the use of Humanitarian
Use Devices based primarily on evidence that the device does
not pose a significant risk of injury to the patient and that
the potential benefit of the device to the health of the patient
outweighs the risks of its use. The NeuroformT Microdelivery
Stent, for treatment of wide-necked intracranial aneurysms, meets
all of the criteria of a Humanitarian Use Device and the FDA
has authorized its use as a Humanitarian Use Device. In other
words, the NeuroformT Microdelivery Stent, when used to treat
a wide-necked, intracranial aneurysm, does not require FDA approval.
It only requires that it meet the criteria the FDA has put in
place for a Humanitarian Use Device. The use of the device does
not involve research or data collection.
The
NeuroformT Microdelivery Stent can be placed in a brain
artery, or a blood vessel in the brain, across the opening of
an aneurysm. After the stent is in place, the aneurysm sac can
be filled with small metal coils. The coils prevent blood from
flowing into the aneurysm and could greatly reduce the risk of
aneurysm rupture. The NeuroformT Microdelivery Stent is a small
metallic mesh tube that is designed to keep the coils in the
aneurysm sac.
If you meet certain requirements, you may be eligible to participate:
The Neuroform T Microdelivery Stent System
is for use with embolic coils for the treatment of wide-neck,
intracranial, saccular aneurysms arising from a parent vessel
with a diameter greater than or equal to 2mm and less than
or equal to 4.5mm that are not amenable to treatment with surgical
clipping. Wide neck aneurysms are defined as having a neck
greater than or equal to 4mm or a dome-to-neck ratio of less
than 2.

The SAPPHIRE WW Registry is a multi-center clinical research
study that will evaluate the effects of a system using two new
investigational devices to treat carotid artery disease. Carotid
artery disease is a blockage or hardening in one or more of the
blood vessels in the neck.
The carotid artery supplies blood to
the head and brain. If the blood supply to the brain is blocked
or reduced, it may result in weakness, pain, or difficulties
with speech, hearing or vision. It may also result in stroke,
a condition resulting from a lack of oxygen in the brain. It
is often caused by interrupted blood flow or coma, a prolonged
loss of consciousness. Increasing the blood flow by enlarging
the blood vessel at the point of narrowing or blockage may
lessen or reverse symptoms associated with the reduced blood
flow.
The investigational system being studied includes two investigational
devices. The first device is called the Cordis PRECISE â Nitinol
Stent System. The stent is permanently placed inside the carotid
artery and can only be removed by a surgical procedure, although
it is highly unlikely that such a procedure would be necessary.
The stent is placed at the part of the artery that is narrowed
or blocked, and it expands after it is placed in the artery.
When the stent expands, it is meant to keep the carotid blood
vessel open, which allows more blood to flow through it to the
brain. The device is approved by the United States Food and Drug
Administration (FDA). Other PRECISE â stents may be used
once they are approved by the FDA.
The second investigational device is called the Cordis ANGIOGUARD ä XP/RX
Emboli Capture guidewire (ECGW). The ECGW is used for protection
during the placement of the PRECISE â Nitinol Stent System.
The ECGW is a tiny filter basket at the end of the Guidewire
in the shape of an umbrella. When the device is opened, it acts
as a filter or strainer, allowing blood to flow through it while
at the same time collecting any particles, such as pieces of
the blockage, that may be dislodged or break off from the lesion
during the procedure. After the stent is placed and expanded
in the blood vessel, the filter is closed and removed from the
vessel. This device is also approved by the FDA for use during
the treatment of carotid artery disease.

Breast cancer is the most common cancer and the second leading
cause of cancer death in women. Death is sometimes caused by
to the spread of breast cancer to other body systems or metastatic
breast cancer (MBC). An increasingly frequent cause of death
in patients with MBC is brain metastasis, or cancer in the brain.
The Early Detection of Brain Metastases From Advanced Breast
Cancer Through Education and Screening is being done to
look at the potential value of routine brain imaging in the detection
of brain metastases in subjects with advanced breast cancer.
It is hoped that information will help doctors in the early detection
of brain metastases. The study is also being done to increase
awareness about brain metastases in breast cancer patients and
the potential benefits of early detection and treatment options
available.
Participants in the study must have previously been diagnosed
with advanced breast cancer. For the study, advanced breast cancer
includes HER-2 positive Stage III or Stage IV breast cancer.
Stage III breast cancer is breast cancer that has spread to 4
or more lymph nodes in the armpit, or has spread to the chest
wall, skin, or to lymph nodes near the breastbone or collarbone.
HER-2 stands for human epidermal growth factor receptor 2. HER-2
helps control how cells grow, divide and repair themselves. Each
healthy breast cell contains 2 copies of HER-2, which helps normal
cells grow. Sometimes a cell may have too many copies of HER-2.
Breast cancer that has too much HER-2 is referred to as HER-2
positive. Stage IV breast cancer is breast cancer that has spread
outside of the breast to bones, lungs, brain or other distant
lymph nodes or organs in the body, also called metastatic breast
cancer, or MBC.
If you meet certain requirements, you may be eligible to participate:
A. Subjects must have an initial primary diagnosis of high-risk
and/or HER-2 positive breast cancer. For purposes of this screening
study, high-risk breast cancer at initial diagnosis is defined
as:
» Stage IV disease, or
» HER-2 positive Stage III disease
B. Subjects must be > = 18 years old.
C. Subjects must be within three to twenty-four months of
first metastases or Stage IV diagnosis or within 12 to 24 months
of initial diagnosis of HER-2 positive Stage III disease.
D. Subjects must sign a written³ informed consent form approved
by the Institutional Review Board (IRB).

The purpose of the study is to evaluate the effectiveness, safety,
and performance of DuraGen Plus ® Adhesion Barrier Matrix,
a device intended to prevent or minimize adhesions or scars that
may develop after operations on the spine. Adhesions and scars
that form on organs after surgery are common and may be responsible
for chronic pain and limited movement. Adhesions are fibrous
structures that connect tissues or organ surfaces that are not
normally joined. Adhesion formation is an undesirable side effect
of the body's normal healing processes following tissue injury.
The DuraGen Plus ® Adhesion Barrier Matrix
has already been cleared for marketing by the United States Food
and Drug Administrations (FDA) as a dural substitute for the
repair of the dura mater, a protective lining of the brain and
spinal cord. The study will specifically evaluate the use of
DuraGen Plus to minimize adhesions and scars after lumbar discectomy,
a surgery to repair a ruptured or slipped disk in the back.
If you meet certain requirements, you may be eligible to participate:

The purpose of the research is to study a new device, known
as the Spinal Sealant System. The study will investigate whether
or not use of the Spinal Sealant System is better than standard
methods used to seal the dura to stop cerebrospinal fluid, or
CSF, from leaking during spinal surgery.
The lining that covers your brain and spinal cord is called
the dura, which holds in CSF. CSF provides a liquid cushion for
the brain and spinal cord. In order to perform surgery, a doctor
makes an opening in the dura. At the end of the surgery, the
dura must be closed in order to stop CSF from leaking out of
the opening. A doctor closes the opening in the dura with stitches.
He or she may also use a piece of muscle or fat, or other soft
tissue taken from another place on your body to help close the
hole and prevent a CSF leak.
The Spinal Sealant is made of two liquids. When mixed, the liquids
form a gel that is mostly made up of water. The gel looks and
feels somewhat like a soft contact lens. After the doctor closes
the opening in the dura with stitches, the gel is applied over
the stitches. It acts as a thin, stretchy film meant to stop
CSF from leaking through the stitches until the area heals on
its own. The gel is blue so the doctor can see where it has been
applied. The body naturally breaks down the gel one to two months
after it is applied. It is removed through urine. The gel is
currently used in brain surgery. The Spinal Sealant System study
will test its use in spinal surgery.
If you meet certain requirements, you may be eligible to participate:

The Total Facet Arthroplasty System, or TFAST is being investigated
to determine its safety and effectiveness for treating patients
with lower back problems. TFAST and the surgical instruments
used to insert the device are the experimental part of the study.
Lumbar spinal stenosis is a narrowing of the space surrounding
the spinal cord in the lower back and/or the nerve roots, that
is, the nerves going from the spinal cord into the buttocks and
legs. The narrowing may be caused by arthritis, the swelling
of a joint, or by an overgrowth of bone on the vertebra, which
are the bones of the spine. Narrowing puts pressure on nerves
and causes uncomfortable lower back, buttock, and/or leg symptoms.
Patients may benefit from a surgical procedure to remove bony
pieces called facets and laminae from the back of one of the
lumbar vertebra. The device being used in the study is meant
to replace the bone that is removed from the vertebra so that
patients are able to maintain movement and stability at the same
particular level of the spine.
If you meet certain requirements, you may be eligible to participate:
