Safety and Efficacy of the Vascular Closure Device (Tonbridge) in Hemostasis Treatment of Femoral Artery Puncture

Safety and Efficacy of the Vascular Closure Device (Tonbridge) in Hemostasis Treatment of Femoral Artery Puncture: A Prospective, Multicenter, Randomized Controlled, Non-inferiority Trial

The purpose of this study is to verify the safety and efficacy of the Vascular Closure Device (Tonbridge) in hemostasis treatment for femoral artery puncture.

Study Overview

• Status: Completed
• Conditions: Hemostasis; Vascular Closure; Puncture; Femoral Artery; Endovascular Procedure
• Intervention / Treatment: Device: Vascular Closure Device (Tonbridge); Device: EXOSEAL Vascular Closure Device (Codis Corporation)

Detailed Description

This is a prospective, multicenter, randomized control, non-inferiority clinical trial carried out in 7 centers throughout China. 228 subjects with hemostasis of femoral artery puncture will be treated with the Vascular Closure Device (Tonbridge) or the EXOSEAL Vascular Closure Device (Codis Corporation). The primary objective of this study is to evaluate the safety and effectiveness of the vascular closure device in hemostasis treatment for femoral artery puncture.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Immediate hemostasis success rate	Immediate hemostasis success is defined as no significant blood oozing and no visible or palpable expanding or developing hematoma on femoral artery puncture site within 5 minutes, once completing the closure operation of femoral artery puncture site using vascular closure device.	intra-procedure

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Time to hemostasis	The time it takes (unit: minute) to reach no significant blood oozing and no visible or palpable expanding or developing hematoma on femoral artery puncture site, once completing the closure operation of femoral artery puncture site using vascular closure device.	intra-procedure
Incidence of device deficiency	Device deficiency is the unreasonable risk that may endanger human health and life safety under normal use of medical devices during clinical trials, such as labeling errors, quality problems and malfunctions, etc.	intra-procedure
Incidence of adverse events (AE)	"Incidence of adverse events" is the proportion of subjects with adverse events using the investigational device or the comparator.	30±7 days post-procedure
Incidence of serious adverse events (SAE)	"Incidence of serious adverse events" is the proportion of subjects with serious adverse events using the investigational device or the comparator.	30±7 days post-procedure
Incidence of complications associated with femoral artery access	"Incidence of complications associated with femoral artery access" is the proportion of subjects with femoral artery access complications using the investigational device or the comparator.	30±7 days post-procedure
