Abstract
A deployment system for forming an incision in a target vessel, for placement of an anastomosis device and for deployment of an anastomosis device having an inner flange formed by radial expansion of the device and an outer flange formed by axial compression of the device.
Claims18
A deployment system for forming an incision in a wall of a target vessel and delivering an anastomosis device for connecting an end of a graft vessel to a target vessel at the site of the incision, the deployment system comprising:
- a holder tube;
- a deployment tube for cooperating with the holder tube;
- and
- a rotatable control, whereby rotation of the control causes relative slidable movement between the holder tube and and the deployment tube.
An anastomosis device deployment system comprising:
- a tool having a rotatable control member;
- a holder tube attached to the tool, the holder tube having a distal end configured to hold the anastomosis device with an attached graft vessel;
- and
- an deployment member positioned within the holder and slidable with respect to the holder to a position at which the deployment member is positioned within the anastomosis device and thereby deploys the anastomosis device.
A method of performing anastomosis comprising:
- providing a deployment tool having a trocar, an expander, a holder tube holding a one-piece tubular anastomosis device having an end of a graft vessel everted around the anastomosis device, and a rotatable control knob for moving the trocar, the expander tube and the holder tube relative to one another;
- rotating the control knob to puncture a target vessel with the trocar;
- rotating the control knob to insert the tubular anastomosis device with everted graft vessel into the puncture in the target vessel;
- rotating the control knob to radial expanding the tubular anastomosis device with the expander to cause a portion of the anastomosis device to fold outward forming a first annular flange;
- and
- rotating the control knob to form a second annular flange on the anastomosis device to trap a wall of the target vessel between the first and second annular flanges and seal the graft vessel to the target vessel.
