Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a prospective, non-randomized study designed to assess the feasibility of the TAMBE Device in the treatment of patients with aortic aneurysms involving the visceral branch vessels. A maximum of 10 Subjects will be treated under this Protocol. This clinical study will include up to six sites in the US. Each enrolled subject will undergo periodic follow-up evaluations involving physical exams, contrast-enhanced computed tomography (CT) of chest, abdomen and pelvis, creatinine measurement, abdominal ultrasound (optional) at specific, protocol-defined intervals for a period of five years following the GORE® EXCLUDER® Thoracoabdominal Branch Endoprosthesis implant.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Experimental: TAMBE Device
Study designed to assess the feasibility of the GORE® EXCLUDER® Thoracoabdominal Branch Endoprosthesis (TAMBE Device) in the treatment of patients with aortic aneurysms involving the visceral branch vessels. Patients with thoracoabdominal or pararenal abdominal aortic aneurysms are eligible for screening for participation in the study. The particular characteristics of the patient's aneurysm and anatomy will determine ultimate eligibility for enrollment. Only patients who meet all of the eligibility criteria will be enrolled.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Absence of procedural safety events through 30 days post procedure

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Absence of Type I and Type III endoleaks
One Month followup
Technical Success, Including Individual Components of Technical Success

Components of Device Integrity: Loss of functional patency in any treated branch component due to thrombus or mechanical failure of branch component, loss of functional patency in main body component(s) due to thrombus or mechanical failure of main body components(s) , separation of treated branch component from the main body component(s), separation of the main body component(s) from the accessory components
12-month
Patency (Primary, Assisted Primary, and Secondary)
