During a minimally-invasive, robotic closed-chest bypass procedure, the da Vinci® Surgical System, a robot designed to facilitate minimally-invasive surgery, can be employed with an adjunctive mediastinotomy to perform coronary anastomosis using the Cardica® C-Port® Flex-A® System during cardiac revascularization. Patients undergoing closed-chest CABG procedures may be discharged in 24 to 48 hours following surgery, and often return to normal activity levels within one to two weeks.

In the past, surgeons needed to guide the robot arms outside the patient’s body to manually suture very small graft vessels during bypass surgery, an extremely demanding and technically challenging process. By precisely and reliably connecting the graft vessel, the Cardica® C-Port® Flex-A® system eliminates the need for a manual anastomosis through a limited thoracotomy, which has been the primary gating factor for minimally-invasive bypass procedures.

Cardica® C-Port® Flex-A® Anastomosis System (Flex-A system)

  The Flex-A system, with its flexible shaft, allows surgeons to perform vessel connections in areas of the heart that are difficult to reach using hand-sewn anastomoses.

The C-Port Flex-A system is designed to:

"Works on very small coronary arteries."

  • Improve quality, reliability and consistency of bypass graft connections
  • Reduce operating time and cost during robotic CABG procedures
  • Allow surgeons to position the device to create a secure connection even in difficult to reach areas of the heart
  • Facilitate minimally-invasive, closed-chest CABG surgery
  • Create compliant anastomoses in vessels great than 1.3 millimeter in internal diameter
  • Be used in either on- and off-pump CABG procedures

A clinical study demonstrated that 95% of the graft vessels studied following an anastomosis with the C-Port device were found to be open in angiograms performed at 6 months postoperatively. To view this study, click here.
