1. An implantable system comprising:
- a cuff;
a surface defining channels; and
a clip having arms that extend into the channels, the arms travelling along the channels during a transverse linear movement of the clip relative to the cuff between an unlocked position of the clip and a locked position of the clip,the clip permitting the cuff to be coupled about a cannula when the clip is in the unlocked position, and the clip being configured to secure the cuff relative to the cannula when the clip is in the locked position.

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.

12. An implant comprising:
-
a cuff defining an opening configured to receive a cannula coupled to a heart pump;
the cannula including a flange, a circumferential ridge, an attachment portion between the flange and the circumferential ridge, and an inflow portion;
the attachment portion having an outer diameter greater than an outer diameter of the inflow portion;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 coupling mechanism being configured to capture the cuff about the cannula between the flange and the circumferential ridge; and a locking mechanism configured to secure the coupling mechanism in the second position, wherein the locking mechanism is configured to be moved to a locked position after the coupling mechanism is in the second position. - View Dependent Claims (13, 14, 15, 16)

17. An implant comprising:
-
a cuff defining an opening configured to receive a cannula coupled to a heart pump; 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 coupling mechanism including an attachment member coupled about the opening of the cuff, the attachment member having one or more flanged portions that extend outward from the opening; and a locking mechanism configured to secure the coupling mechanism in the second position, the locking mechanism being configured to be moved to a locked position after the coupling mechanism is in the second position, the locking mechanism including a clip configured to engage the one or more flanged portions to limit movement of the cuff relative to the cannula, the clip being configured to enter a slot in the heart pump to secure the cuff to the heart pump. - View Dependent Claims (18, 19, 20)
