Active clinical trials for "Aneurysm"

The use of a suprarenal extension device during the index AAA procedure to accommodate the patient's anatomy and to prevent or repair leakage.

This study was a prospective observational study examined the safety of the TriVascular AAA Stent-Graft System in the elective treatment of patients with abdominal aortic aneurysms. Specifically, the study will evaluate the safety of the TriVascualr AAA Stent-Graft System, evaluate the ability to deliver the Tri-Vascular AAA Stent-Graft System to the desired location within the aorta, and evaluate the ability of the TriVascular AAA Stent-Graft to exclude the abdominal aortic aneurysm.

This is a randomized, double-blind, placebo-controlled, single-dose, design investigating the safety, tolerability and efficacy of NA-1, a peptide designed to reduce ischemic brain damage. Up to 200 male and female patients undergoing endovascular repair of brain aneurysm will be dosed with 2.60 mg/kg of NA-1 or placebo as a 10 minute intravenous infusion after completion of the endovascular procedure on Day 1 of the study period. Subjects will undergo interim procedures Days 2-4 and end-of study procedures on Day 30. Standard safety criteria will be analysed. Efficacy endpoints include the ability of NA-1 to: 1) reduce the volume of ischemic embolic strokes, 2) reduce the number of ischemic embolic strokes, 3) reduce vascular cognitive impairment, and 4) reduce the frequency of large strokes induced by the endovascular procedure. The plasma concentrations of NA-1 will also be analyzed.

The Zenith® TX2® Low Profile TAA Endovascular Graft study is a clinical trial approved by US FDA to evaluate the safety and effectiveness of the Zenith® TX2® Low Profile TAA Endovascular Graft indicated for the treatment of patients with aneurysms/ulcers of the descending thoracic aorta having vessel structure suitable for repair.

Flow diverters are a recent addition to the range of endovascular devices now available for the treatment of intracranial aneurysms. The FIAT trial aims at comparing flow diversion to best standard treatment in the context of a randomised controlled trial. Best standard treatment may include any of the following and will be left to the treating physician to decide : 1) conservative management; 2) coiling with or without high porosity stenting; 3) parent vessel occlusion with or without bypass; 4) surgical clipping. If the only treatment alternative is deemed to be flow diversion for compassionate use, then randomisation will not be carried out, but patient will enter a registry and her data recorded according to same schedule as randomised patients. The primary hypothesis is that flow diversion can be performed with an "acceptable" immediate complication rate, defined as less than 15% morbidity and mortality, AND increase the number of patients experiencing successful therapy, defined as complete or near complete occlusion of the aneurysm from 75 to 90%, relative to best standard treatment.

This research study is being done to test the effectiveness of a new generation FDA approved device for treating aneurysms compared to the current standard device for endovascular aneurysm treatment which is bare platinum coils. Endovascular procedures are a form of minimally invasive surgery, which is performed on blood vessels. The technique involves the introduction of a catheter which is a long, thin, flexible, hollow plastic tube through the skin into a large blood vessel. Typically the chosen blood vessel is the femoral artery found near the groin. The catheter is then maneuvered through the body to the location of the aneurysm in the brain using image guidance. Coils are delivered into the aneurysm through the catheters. Once the coils are delivered in the aneurysm, they are detached from the catheter. This is repeated until enough coils fill the aneurysm, blocking the blood flow to the aneurysm. The body responds by forming blood clots around the coil(s), which helps block the flow of blood into the aneurysm and keeps the vessel from rupturing or leaking. This study will compare the study device to the standard bare platinum coil to see which is better at preventing future rupturing or leaking. The study device is called the HydroCoil Embolization System and this study is a post-market clinical trial. About 600 subjects from multiple institutions will take part in this study.

The primary outcome of this study was the evaluation of the efficacy of TAP block on pain intensity following open abdominal aortic surgery.

The study is a prospective, multi-center, randomized, open, parallel positive control, non-inferiority trial. Patients are randomized 1:1 to either Coil System(Ton-bridgeMT) or Axium Detachable Coil(Medtronic). The purpose of this study is to assess the safety and effectiveness of the Coil System(Ton-bridgeMT) in the treatment of intracranial aneurysms.

The purpose of this study is to evaluate the use of an investigational device called the ValiantTM Visceral Manifold Thoracoabdominal Stent Graft System for the repair of thoracoabdominal aortic aneurysms (TAAA), which is a balloon-like bulge in the aorta (major artery leading away from your heart) that originates in your chest and extends to your abdomen and also includes the branch arteries that supply blood to the liver, spleen, intestine, kidneys and other organs in your abdomen. The word "investigational" means the device is still being tested and is not approved by the Food and Drug Administration (FDA) for sale in the United States.

This trial is conducted to evaluate the safety and technical effectiveness of using NCVC-CS1, a newly developed honeycomb microporous covered stent, for the treatment of intracranial aneurysms which are difficult to be cured by conventional surgical or endovascular procedures.
