Abstract

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.

Claims Analysis

Total Claims: 8

Claim 1

Independent Claim 105 words

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.

Claim 2

Dependent Claim 105 words

Claim 3

Dependent Claim 16 words

The connector of claim 1 wherein the petal defines at least one aperture within the petal.

Claim 4

Dependent Claim 13 words

The connector of claim 1 wherein the petal comprises a memory elastic material.

Claim 5

Dependent Claim 42 words

The connector of claim 1 further comprising a plurality of petals extending from the base along a line that forms an angle of between thirty and ninety degrees with a longitudinal fitting axis that is generally parallel to the two opposing sides.

Claim 6

Dependent Claim 26 words

The connector of claim 1 further comprising a compression ring configured to secure the fitting to a vessel when the fitting is in the deployed configuration.

Claim 7

Dependent Claim 39 words

The connector of claim 5 wherein the fitting comprises at least one tab configured to self-expand when the fitting is in the deployed configuration to protrude radially from the base and to secure the compression ring to the fitting.

Claim 8

Dependent Claim 25 words

The connector of claim 1 further comprising a loading sheath defining a central lumen adapted to receive and compress the fitting into the deployed configuration.
