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.

Patent number: 11331466Abstract: Disclosed herein is an inflow cannula for an implantable blood pump assembly. The inflow cannula includes a tubular body that extends from a proximal end to a distal end. The tubular body includes a proximal portion adapted for connection to a pump housing, and a distal portion adapted for positioning within an opening formed in a heart. The inflow cannula further includes an expandable sleeve coupled to an exterior surface of the distal portion. The sleeve has a first portion coupled to the distal portion of the tubular body, and a second portion extending from the distal end of the tubular body. The second portion is deployable from a first, stored configuration to a second, deployed configuration in which the second portion expands radially to engage and conform to an endocardial surface of the heart.Type: GrantFiled: January 16, 2020Date of Patent: May 17, 2022Assignee: TC1 LLCInventors: Rachel Keen, Steve Franklin, Tracee Eidenschink, Ted Dale, Gary Erzberger, Kristopher Vietmeier, Julien Duhamel, Francheska Torres

Patent number: 10737007Abstract: A patient adapter for connecting a driveline cable between an implantable blood pump and a controller. The patient adapter provides a sufficiently large form factor to make connecting ends of a driveline cable easy for patients who lack dexterity or have unclear vision. The patient adapter includes an adapter body that defines a central lumen that extends through an entire length of the adapter body. The central lumen is configured to receive an end of a percutaneous end connector of the driveline cable and an end of a controller end connector of the driveline cable. The patient adapter includes a first mating feature configured to engage a corresponding feature of the percutaneous end connector and a second mating feature configured to engage a corresponding feature of the controller end connector. A thickness of the adapter body is greatest at a position proximate the controller end connector.Type: GrantFiled: April 30, 2018Date of Patent: August 11, 2020Assignee: TC1 LLCInventors: Julien Duhamel, John Mark Di Paola, Dustin Roelle, Dmitry Protsenko

Patent number: 9526818Abstract: A protective cap for fluidly sealing a connector of a cable is provided. The protective cap includes a flexible body having an interior cavity with a distal opening through which the connector is inserted. The distal opening is defined by an annular ridge that engages a cable portion proximal the connector to fluidly seal the entire connector within the cavity. The body portion may have an oval-shaped cross-section while the interior cavity is cylindrical so that the portions wider portions of the body provide longitudinal rigidity to facilitate installation and removal of the cap by a manual pushing and pulling. A tether may be included to attach the cap to a distal portion of the cable. The protective cap and tether may be integrally formed of a soft, highly flexible material to improve ease of use, biocompatibility and patient comfort.Type: GrantFiled: April 15, 2015Date of Patent: December 27, 2016Assignee: THORATEC CORPORATIONInventors: Keith Hamilton Kearsley, Gabe Wegel, Kathryn B.
