In one general aspect, a cuff for attachment to a heart includes an attachment component configured to engage a blood pump to attach the cuff to the blood pump and a sewing ring for attachment to the heart. The sewing ring is coupled to the attachment component, and the attachment component and the sewing ring each define a central opening configured to admit an inflow cannula of a blood pump. The sewing ring comprises a member that provides rigidity to flatten a portion of a myocardium of the heart when the cuff is attached to the heart.

Ventricular cuff

A fluid treatment system for a percutaneous cable and methods of assembly and use are described herein. In one aspect, the fluid treatment system includes a delivery tube comprising a distal end and a proximal end. The distal end is configured to surround at least a portion of the percutaneous cable. The percutaneous cable extends from within a patient to outside the patient through tissue at an exit site. The proximal end is connectable to a fluid source. Fluid from the fluid source is configured to be delivered to the exit site through the delivery tube. The fluid treatment system includes an anchor coupleable to the percutaneous cable to secure the percutaneous cable to the tissue at the exit site.

Fluid treatment system for a driveline cable and methods of assembly and use

An implantable system includes a ventricular assist device and a cuff for attachment to a heart. The ventricular assist device includes an inlet cannula. The cuff defines an opening for insertion of the inlet cannula into the opening. The cuff includes an annular fastening member and an attachment member. The annular fastening member is configured to be sutured to heart tissue. The attachment member includes flexible extensions. Each of the flexible extensions is configured to interface with the inlet cannula during insertion of the inlet cannula into the opening so as to cause the flexible extension to flex outward to accommodate passing of the inlet cannula along the opening. Each of the flexible extensions is configured to interface with the inlet cannula to impede extraction of the inlet cannula from the opening.

An implantable system includes a ventricular assist device (VAD), a cuff for attachment to a heart, and a latching mechanism attached to the VAD. The VAD includes an inlet cannula. The cuff defines an outward facing circumferential groove and an opening for the inlet cannula. The cuff includes a plurality of ridges disposed at least partially within the outward facing circumferential groove. The latching mechanism is reconfigurable between an unlatched configuration in which the latching mechanism accommodates insertion of the inlet cannula into the opening and a latched configuration in which the latching mechanism is engaged with the cuff to restrain the position of the inlet cannula relative to the cuff and engaged with at least one of the plurality of ridges to block rotation of the VAD relative to the cuff.

The present disclosure provides an apical connector for use in a heart wall. The apical connector may include a port defining an aperture therethrough, an anchoring device extending distally from the port and configured for advancing at least partially through the heart wall, and a cannula configured for advancing through the aperture of the port and at least partially through the heart wall. The cannula may include a locking tab configured to engage the port and lock the cannula with respect to the port.

Apical connectors and instruments for use in a heart wall

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.
