The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
Information provided by (Responsible Party):
Cardica, Inc
  Purpose
The Study plan is a post-market prospective, multi-center, open-label registry. The vein graft failure rates for the currently commercialized C-Port devices will be compared to an a priori rate taken from the peer-reviewed literature.

Condition Intervention Phase
Heart Disease Device: Anastomosis (C-Port® ) Phase 4

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Multi-center Assessment of Grafts in Coronaries: Long-term Evaluation of the C-Port Device

Further study details as provided by Cardica, Inc:

Primary Outcome Measures:
  • Graft patency rates for coronary revascularization when in general use in the United States compared to hand-sewn anastomoses. [ Time Frame: 12 months ]
    a. Acute, midterm, and one-year graft patency rates for coronary revascularization when in general use in the United States compared to hand-sewn anastomoses.


Secondary Outcome Measures:
  • Technical Failure Rates [ Time Frame: Day 1 ]
    Technical failure rates when completing an anastomosis using the C-Port products.

  • Technical success rate of hand-sewn [ Time Frame: Day 1 and 12 months ]
    The technical success rate of hand-sewn anastomoses following technical failures of the C-Port products and the hand-sewn graft patency rates and clinical sequelae at one year.


Enrollment: 115
Study Start Date: April 2009
Study Completion Date: July 2015
Primary Completion Date: January 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: anastomoses in blood vessels and grafts Device: Anastomosis (C-Port® )
creation of anastomoses in blood vessels and grafts, including use in coronary artery bypass grafting procedures
Other Names:
  • C-Port® Distal Anastomosis System
  • C-Port® xA™ Distal Anastomosis System
  • C-Port® FlexA™ Distal Anastomosis System
  • C-Port® XCHANGE™ Distal Anastomosis System

Detailed Description:

To satisfy the requirements set forth in post-market surveillance orders issued by the US FDA to Cardica, Inc., the following outcomes will be evaluated:

  1. Acute, midterm, and one-year graft failure rates for coronary revascularization using the C-Port® xA™ Distal Anastomosis System, C-Port® FlexA™ Distal Anastomosis System, and C-Port® XCHANGE™ Distal Anastomosis System when in general use in the United States compared to hand-sewn anastomoses.
  2. Technical failure rates when attempting to complete an anastomosis using the C-Port xA, FlexA, and XCHANGE Distal Anastomosis Systems.
  3. The technical success rate of hand-sewn anastomoses following technical failures of the C-Port devices and the hand-sewn graft patency rates and clinical sequelae at one year.
