Primary Outcomes

Successful IVD implantation with vas deferens occlusion at 6 and 24 months post-implant.
time frame:
The IVD consists of a tubular silicone plug that is inserted into the lumen of the vas deferens to block the flow of semen.
time frame:
IVD implantation does not require the need to sever or permanently damage the vas deferens like the Ligation/Excision, Clip devices, Cautery
time frame:
techniques or Fascial Interposition require. One major advantage of the IVD is that it
time frame:
does not require excision and removal of a portion of the vas. Implantation of the IVD
time frame:
allows the vas deferens to remain intact and not be permanently damaged.
time frame:

Additional Information

Official title The Intra Vas Device (IVD) As A Means of Male Reproductive Sterilization A Single Armed Feasibility Study
Description This feasibility study is intended to collect pertinent clinical information on the use of the Shepherd Medical Intra Vas Device (IVD) necessary to support the design of a future pivotal study. The IVD is intended to occlude the vas deferens and thus accomplish male reproductive sterilization and to offer an additional method to vasectomy.
