Abstract
A side-to-end vascular anastomosis device comprising a diversion conduit coupled to a lower flange which is inserted into the vessel and an upper flange located on the outside of the vessel designed to clamp together to seal the incision into which the lower flange of the device is inserted.
Claims19
A method of installing a vascular anastomosis device, comprising:
- clamping off flow through a portion of a vascular conduit,
- creating an incision in the vascular conduit for insertion of the vascular anastomosis device,
- inserting a lower flange of the vascular anastomosis device through the incision and into the vascular conduit, and
- clamping the vascular anastomosis device on the vascular conduit using a first spring mechanism and a second spring mechanism, each of the first spring mechanism and the second spring mechanism being connected between an upper flange, and a diversion conduit of the vascular anastomosis device, the diversion conduit being attached to the lower flange and configured to pass movably through an aperture in the upper flange, the first spring mechanism configured to exert a first force biasing the upper flange toward the lower flange and the second spring mechanism configured to exert a second force biasing the upper flange toward the lower flange, the first spring mechanism and the second spring mechanism attached to opposite sides of the diversion conduit.

A method of installing a vascular anastomosis device, comprising:
- making an incision in a vascular conduit;
- inserting a lower flange of the vascular anastomosis device through the incision such that an upper flange, in a position separated from the lower flange, is positioned external to the incision;
- and
- moving the upper flange from its separated position to a second position to clamp the vascular conduit between the upper and lower flanges using a first spring mechanism and a second spring mechanism attached to opposite sides of a diversion conduit of the vascular anastomosis device and extending between the upper flange and the diversion conduit, the diversion conduit being attached to the lower flange and configured to pass movably through an aperture in the upper flange, the spring mechanism configured to exert a first force biasing the upper flange toward the lower flange and the second spring mechanism configured to exert a second force biasing the upper flange toward the lower flange.

- and
- holding portions of the vascular conduit at sides of the incision in place using texturing on a surface of the vascular anastomosis device.
