Ventricular cuff
First Claim
Patent Images
1. A method of attaching a ventricular assist device to a patient, comprising:
- attaching a cuff having a groove to a heart, the cuff defining an opening;
inserting a cannula through the opening of the cuff to a predetermined position relative to the cuff; and
moving a clip in a transverse linear motion relative to the cuff into engagement with the groove to restrain the cannula in the predetermined position relative to the cuff.

Abstract
In one general aspect, an implant includes a cuff defining an opening configured to receive a cannula coupled to a heart pump. The implant includes a coupling mechanism having a first position and a second position, the cuff being uncoupled from the cannula in the first position and the coupling mechanism coupling the cuff to the cannula in the second position. The implant includes a locking mechanism configured to secure the coupling mechanism in the second position, and the locking mechanism is configured to be moved to a locked position after the coupling mechanism is in the second position.

9. A method of attaching a ventricular assist device to a patient, comprising:
-
attaching a cuff to a heart; inserting a cannula through an opening of the cuff to a predetermined position relative to the cuff, wherein the cuff has a groove and a plurality of ridges disposed at least partially within the groove; and engaging a latching mechanism configured to restrain the cuff in the predetermined position relative to the cannula and to come into engagement with least one of the plurality of ridges to block rotation of the cuff relative to the cannula. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A method of attaching a ventricular assist device to a patient, comprising:
-
attaching a cuff to a heart; positioning a cannula through an opening of the cuff; moving a clip in a transverse linear motion relative to the cannula from an unlocked position to a locked position, wherein the clip blocks movement of the cannula relative to the cuff in the locked position; disengaging the clip from the cuff in the locked position to the unlocked position; repositioning the cannula with respect to the cuff; and reengaging the clip into the locked position. - View Dependent Claims (21, 22, 23)

24. A method of attaching a ventricular assist device to a patient, the method comprising:
-
attaching a cuff to a heart, the cuff defining an opening; inserting a cannula having a circumferentially extending ridge through the opening of the cannula; constricting a clamp to a constricted configuration to deform a circumferential portion of the cuff toward the cannula such that the deformed portion of the cuff blocks a movement of the circumferential extending cannula ridge relative to the cuff; and engaging a locking member that secures the clamp in the constricted configuration. - View Dependent Claims (25)

26. A method of attaching a ventricular assist device to a patient, comprising:
- attaching a cuff to a heart;
positioning a cannula through an opening of the cuff; and
moving a clip in a transverse linear motion relative to the cannula from an unlocked position to a locked position, wherein the clip blocks movement of the cannula relative to the cuff in the locked position, wherein the clip has opposing curved resilient arms defining an opening configured to interface with the cuff, and wherein moving the clip from the unlocked position to the locked position forces the arms laterally outward to expand the opening to receive the cuff. - View Dependent Claims (27)
