Publication number: 20240099868Abstract: An assembly includes an implant and a control lead. The implant includes a tubular implant body, a circumferentially adjustable sealing collar coupled to the implant body, a rotatable sealer gear coupled to the sealing collar and configured to adjust the circumference of the sealing collar, and a locking member having a locked state and an unlocked state. The control lead is configured for rotating the locking member and moving the locking member from the locked state to the unlocked state. In the locked state, rotating the control lead does not adjust the circumference of the sealing member. In the unlocked state, rotating the control lead in a first direction rotates the locking member and the sealer gear and circumferentially expands the sealing collar. In the unlocked state, rotating the control lead in a second direction rotates the locking member and the sealer gear and circumferentially contracts the sealing collar.Type: ApplicationFiled: December 5, 2023Publication date: March 28, 2024Inventors: Richard George Cartledge, John P.
