Patent number: 12109100Abstract: Resorbable three-dimensional implants that can be temporarily deformed, implanted by minimally invasive means, and resume their original shape in vivo, have been developed. These implants are particularly suitable for use in minimally invasive procedures for tissue reinforcement, repair of hernias, and applications where it is desirable for the implant to contour in vivo to an anatomical shape, such as the inguinofemoral region. In the preferred embodiment, the implants are made from meshes of poly-4-hydroxybutyrate monofilament that have reinforced outlying borders that allow the meshes to form three-dimensional shapes that can be temporarily deformed. These implants can resume three-dimensional shapes after being temporarily deformed that contour to the host's tissue or an anatomical shape, for example, in the repair of a hernia, and particularly a hernia in the inguinofemoral region.Type: GrantFiled: May 30, 2019Date of Patent: October 8, 2024Assignee: Tepha, Inc.Inventors: Said Rizk, Amit Ganatra, Antonio Fosco, David P.

Patent number: 11207166Abstract: In one embodiment, an apparatus includes a support portion disposable within a pelvic region and a strap extending from the support portion. The strap has a length and is configured to be disposed at least partially within a pelvic tissue. A sleeve is releasably disposed over at least a portion of the strap. The sleeve has a length that is longer than the length of the strap. In some embodiments, the length of the sleeve is at least twice as long as the length of the strap. In some embodiments, a suture couples the sleeve to the strap. The apparatus can also include a suture disposed at least partially within an interior of the sleeve and forming two strands of suture within the interior of the sleeve. The two strands are separated by a distance defined by a separator portion of the sleeve.Type: GrantFiled: April 30, 2018Date of Patent: December 28, 2021Assignee: Boston Scientific Scimed, Inc.Inventor: Michael S. H. Chu

Patent number: 11185414Abstract: A heart implant alignment and delivery device includes an elongate body having an opening that is disposed near a distal end of the elongate body. The opening is configured so that a heart implant is positionable within the opening with the heart implant exposed to a surrounding environment and so that the heart implant is substantially aligned with the distal end of the elongate body. The device also includes an implant reposition member, such as a cable, that is releasably coupleable with the heart implant and that is operationally coupled with the elongate body so that a first operation of the implant reposition member causes the heart implant to be retractably deployed from the opening of the elongate body. The first operation of the implant reposition member may be effected via a handle mechanism that is attached to a proximal end of the elongate body.Type: GrantFiled: February 13, 2019Date of Patent: November 30, 2021Assignee: BioVentrix, Inc.Inventors: Kevin Van Bladel, Meir Moshe, Michael S. Dana
