Clinical Trial of the WC360 SiteSeal Adjunctive Compression Device Following Interventional Endovascular Procedures

Not Applicable

• Conditions: Bleeding
• Interventions: Device: SiteSeal Endovascular

• Registration Number: NCT03234894
• Lead Sponsor: Wound Care 360, Inc.

Brief Summary

This Clinical Study is a pivotal study to evaluate the safety of the SiteSeal™ Adjunctive Compression Device across a broad array of patients undergoing interventional endovascular procedures.

Detailed Description

The study design is a single arm with 90 patients. The primary endpoints measure the risk for common femoral nerve damage and common femoral artery laceration from the blind placement of a Z-stitch in the soft tissue above the femoral bundle.

The sample size is 90 patients. The project objective is to demonstrate the safety of the device.

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: SINGLE_GROUP

Arm && Interventions

Group	Intervention	Description
SiteSeal Endovascular	SiteSeal Endovascular	After intervention (deployment and removal of the Site Seal endovascular adjunctive compression device), the physician determines whether or not there was laceration of the femoral nerve or laceration of the femoral artery per protocol. A series of possible minor and/or major complications are noted per protocol. There is a secondary metric as to patient reported pain on a 1-10scale.

Primary Outcome Measures

Name	Time	Method
The percent of patients with common femoral nerve damage or with bleeding from femoral artery laceration from the blind placement of a Z-stitch in the soft tissue above the femoral bundle.	24 hours	Femoral damage is indicated if the patient has an audible response during suture placement. Arterial laceration is visible bleeding during suture placement.

Secondary Outcome Measures

Name	Time	Method
Patient-rated patient discomfort.	24 hour interview	Patients are called back after 24 hours and asked to rate their discomfort on a 1-10 scale. The mean of all patients 1-10scale rating is reported as the discomfort of the arm.
The percent of patients who had a major complication.	30day interview	Major complications are defined in the protocol. Major complications are summed and the mean of the entire arm is reported as a percent of patients who had major complications.
The percent of patients who had a minor complication.	30day interview	Minor complications are defined in the protocol. Minor complications are summed and the mean of the entire arm is reported as the percent of patients who had minor complications.
