Publication number: 20220296876Abstract: 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.Type: ApplicationFiled: May 24, 2022Publication date: September 22, 2022Applicant: TC1 LLCInventors: Justin Aron Callaway, Cori G. Pierce, Julien Duhamel, Kevin Bourque, J. Donald Hill, Terry Barnes, Dustin Seth West, Peter Gazzara, III

Patent number: 11185683Abstract: 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.Type: GrantFiled: December 5, 2019Date of Patent: November 30, 2021Assignee: TC1 LLCInventors: Justin Aron Callaway, Christopher James Cotter, Cori Pierce, Maria Dominika Kulinski, Ben Gamulo, Kevin Bourque, Jeff Narum

Patent number: 10525177Abstract: 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.Type: GrantFiled: July 30, 2018Date of Patent: January 7, 2020Assignee: TC1 LLCInventors: Justin Aron Callaway, Christopher James Cotter, Cori Pierce, Maria Dominika Kulinski, Ben Gamulo, Kevin Bourque, Jeff Narum
