Abstract
A single integrated tool is used both to create an opening in a vessel wall and deploy an anastomosis device into that opening, thereby simplifying an anastomosis procedure such as a coronary artery bypass graft procedure. The creation of the opening and deployment of the anastomosis device may be actuated with a single control.
Claims45
An integrated anastomosis tool for connecting a graft vessel having a lumen therein to a target vessel, comprising:
- a first mechanism configured to create an opening in the target vessel;
- a second mechanism configured to complete an anastomosis with the target vessel;
- a seal housing within which both said first mechanism and said second mechanism travel;
- and
- a single control configured to operate both said first mechanism and said second mechanism.
An integrated anastomosis tool for connecting a graft vessel having a lumen therein to a target vessel, comprising:
- a first mechanism configured to create an opening in the target vessel;
- a second mechanism configured to complete an anastomosis with the target vessel;
- and
- a single control configured to operate both said first mechanism and said second mechanism;
- wherein at least a part of said first mechanism is moved along a first axis to create the opening in the vessel wall, and wherein said at least a part of said first mechanism is configured to move away from said first axis before said second mechanism deploys said anastomosis device.
An integrated anastomosis tool for connecting a graft vessel having a lumen therein to a target vessel, comprising:
- a first mechanism configured to create an opening in the target vessel;
- a second mechanism configured to complete an anastomosis with the target vessel;
- and
- a single control configured to operate both said first mechanism and said second mechanism;
- wherein at least a part of said first mechanism is moved along a first axis to create the opening in the vessel wall, and wherein at least a part of said second mechanism is moved from a position away from said first axis to align substantially with said first axis before said second mechanism deploys said anastomosis device.
An integrated anastomosis tool for connecting a graft vessel having a lumen therein to a target vessel, comprising:
- a first mechanism configured to create an opening in the target vessel;
- a second mechanism configured to complete an anastomosis with the target vessel;
- a single control configured to operate both said first mechanism and said second mechanism;
- and
- a hollow introducer tip configured for placement at least partially into the opening in the target vessel, wherein at least a portion of said first mechanism and at least a portion of said second mechanism pass through said introducer tip.
An integrated anastomosis tool for connecting a graft vessel having a lumen therein to a target vessel, comprising:
- a first mechanism configured to create an opening in the target vessel;
- a second mechanism configured to complete an anastomosis with the target vessel;
- and
- a single control configured to operate both said first mechanism and said second mechanism said single control rotatable about an axis substantially coaxial with the longitudinal centerline of said second mechanism;
- wherein at least one of said first mechanism and said second mechanism is at least partially lubricated with a biocompatible lubricious substance.
