VAS-2 Vasectomy With the Vax-X (VAS-2)

This study has been completed.
Sponsor:
Information provided by (Responsible Party):
John Amory, University of Washington
ClinicalTrials.gov Identifier:
NCT00663533
First received: April 18, 2008
Last updated: December 2, 2014

  Purpose
The purpose of this research study is to study an experimental vasectomy device called the Vas-X. This is an experimental study of this new approach to vasectomy.

Condition Intervention Phase
Healthy Device: Vas-X Phase 1

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Prevention
Official Title: Vasectomy With the Vas-X, a Simple, Minimally Invasive Device for Male Sterilization: A Pilot Study

Further study details as provided by John Amory, University of Washington:

Primary Outcome Measures:
  • absence of sperm in ejaculated semen 6 months after vasectomy [ Time Frame: 6-months ]

Secondary Outcome Measures:
  • any side effects as well as degree of occlusion of the resected segment of vas deferens [ Time Frame: 6-months ]

Enrollment: 10
Study Start Date: April 2008
Study Completion Date: July 2013
Primary Completion Date: July 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: Device study only. Device: Vas-X
mechanical vasectomy device

Detailed Description:

The Vas-X works by stripping the lining of the vas deferens, the tube that sperm pass through during ejaculation. It is used in a way very similar to routine vasectomy, however, in a routine vasectomy, the vas is burned with an electrical device. With the Vas-X, there is no burning. The investigators are testing the Vas-X to determine whether it will offer a better way of performing a vasectomy.

The investigators will conduct this study at the University of Washington Medical Center, Seattle.
