Prospective Clinical Registry Evaluating Contemporary MANTA Outcomes (ACCESS MANTA)

November 10, 2025 updated by: Essential Medical, Inc.
This is an observational study designed to evaluate the safety and clinical outcomes of the MANTA® Vascular Closure Device (VCD) (the MANTA® Device) in TAVR procedures. The study will enroll participants who are undergoing a TAVR procedure. The purpose of this study is to examine and collect data on outcomes of contemporary MANTA® large bore closure in standard of care (SOC) TAVR procedures with on-label use of the MANTA® device including appropriate patient selection and proper vascular access.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

In the U.S. and Canada, the MANTA® Vascular Closure Device is indicated for closure of femoral arterial access sites while reducing time to hemostasis following the use of 10-20F devices or sheaths (12-25F OD) in endovascular catheterization procedures. In Israel, the 14F MANTA® is indicated for closure of femoral arterial access sites following the use of 10-14F devices or sheaths (maximum OD/profile of 18F), and the 18F MANTA® device is indicated for closure of femoral arterial access sites following the use of 15-18F devices or sheaths (maximum OD/profile of 25F). The purpose of the study is to examine and collect data on outcomes of contemporary MANTA® large bore closure in standard of care (SOC) TAVR procedures with on-label use of the MANTA® device including appropriate patient selection and proper vascular access.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

Description

Inclusion Criteria:

  • Candidate meets criteria for on-label use of MANTA® VCD as specified in the country-specific MANTA® VCD Instructions for Use (IFU), per judgement of the investigator.
  • Age ≥21 years

Design Details

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.
Outcome Measure
Measure Description
Time Frame
Rate of VARC-3 Major & Minor Vascular complications
Time Frame: within 30 days of TAVR procedure
within 30 days of TAVR procedure
Time to Hemostasis
Time Frame: During the procedure
The elapsed time between MANTA® deployment and first observed and confirmed arterial hemostasis
During the 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.
Outcome Measure
Measure Description
Time Frame
Additional interventions: Required at large bore access site to address complications
Time Frame: within 30 days following the procedure
The percentage of subjects with additional interventions required at large bore access site to address bleeding or other large bore access site complications (e.g., bare or covered stent or surgical repair), within 30 days following the procedure
within 30 days following the procedure
Technical Success:
Time Frame: During the procedure
The percentage of subjects in whom closure is obtained with the MANTA® VCD without the use of unplanned endovascular or surgical intervention
During the procedure
Treatment Success:
Time Frame: within 30 days of TAVR procedure
The percentage of subjects in whom the time to Hemostasis ≤10 minutes and have no Large Bore Access Related Major VARC-3 complications within 30 days.
within 30 days of TAVR procedure
Ambulation Success:
Time Frame: During procedure admission
The percentage of a previously ambulatory subjects (until day of TAVI) who are able to ambulate for at least 20 feet/6 meters without re-bleeding.
