Brief Summary:
This study will assess the nitinol U-clip as an alternative to conventional microsurgical suture for arterial anastomoses in free tissue transfer.

Condition or disease Intervention/treatment Phase
Microvascular Anastomoses Device: nitinol u-clip Phase 4

Detailed Description:
Within Scott & White, a total of 25 free flaps will be performed using U-clips for microvascular anastomoses in lieu of traditional suturing techniques. Each of these free flaps may be in individual patients or two anastomoses may be included in one patient. Historical controls will be used for comparison of complication rates of U-clip versus sutured anastomoses. Postoperatively, the study participants will be evaluated at 2 weeks (+/- 1 week) and at 3 months (+/- 1 month) follow up.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 25 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Prospective Evaluation of U-clips for Arterial Microvascular Anastomoses
Study Start Date : October 2009
Primary Completion Date : October 2010
Study Completion Date : October 2010

Arm Intervention/treatment
no arms
all patients will receive the treatment - there is only one arms
Device: nitinol u-clip
The U-clip is comprised of nitinol, an alloy of nickel and titanium.
Other Name: Coalescent Surgical U-CLIPTbl

Primary Outcome Measures :
  1. Flap failure rate compared to published rate for conventional suture anastomoses [ Time Frame: will be measured 3 months postoperative (+/- 2 weeks) ]

Secondary Outcome Measures :
  1. Rapid, reproducible, sutureless microvascular arterial anastomoses in free flaps without compromising patient outcomes. [ Time Frame: data collected at 3 months postoperative (+/- 2 weeks) ]
