Patent number: 11583671Abstract: At least some embodiments of the disclosure may advantageously limit bleeding and the occurrence of blood leaks after heart pump implantation. In some embodiments, a base may be provided that includes a flexible layer mechanically coupled with a conduit. The flexible layer may be coupled with the proximal end of the conduit. The conduit may be configured to receive a cannula of the heart pump therethrough. The outer surface of the conduit may be configured to engage a surface of the heart formed after coring the heart. The conduit may be metal and may have a flared and/or beveled distal end. The conduit may be a flexible material. A distal flexible layer may be provided at a distal end of the conduit that is configured to engage with an inner surface of the heart.Type: GrantFiled: January 4, 2021Date of Patent: February 21, 2023Assignee: TC1 LLCInventors: John Duc Nguyen, Huy Ngo, Carine Hoarau, Fabian Franco

Patent number: 11129640Abstract: A cutting edge of a punch includes side segments and a central segment disposed between the side segments. When the punch head slides into a hollow blade, the central segment of the cutting edge meets the punch head before the side segments meet the punch head. The central segment starts cutting first, which can help avoid a dog-bone shaped hole when the punch is used on a blood vessel, such as the aorta.Type: GrantFiled: June 6, 2018Date of Patent: September 28, 2021Assignee: TC1 LLCInventors: John Duc Nguyen, Carine Hoarau, Steven H. Reichenbach, James Badia, Ruth Eleanor Beeby
