Abstract

This invention is related to devices and systems for creating sutureless anastomoses. In particular, this invention is related to devices for deploying and securing the ends of bypass grafts designed to provide a fluid flow passage between at least two vessels or tubular structures. A variety of compressible, expandable fittings, loading and delivery sheaths, tools, and other devices for creating end-end and end-side anastomoses, as well as methods for their use, are disclosed. In addition, robotic, remotely operable systems and devices for creating sutureless anastomoses in minimally invasive applications are disclosed. The systems of this invention do not require stopping or re-routing blood flow to perform an anastomosis between a bypass graft and a host vessel. Accordingly, this invention describes sutureless anastomosis systems that do not require cardiopulmonary bypass support when treating coronary artery disease.

Independent Claims | See all claims (7)

  1. 1. A split wall anastomotic connector comprising: a fitting having a base and two opposing sides, the fitting being thermally formed so that (1) the two opposing sides are spaced apart from one another when the fitting is in a relaxed, undeployed configuration and (2) the fitting is capable of assuming a generally tubular, deployed configuration in which the two opposing sides are closer to one another than when the fitting is in the relaxed, undeployed configuration, the fitting further comprising at least one petal extending from the base, the petal configured to radially expand from the base when the fitting is in the deployed configuration.
