  • Publication number: 20240099868
    Abstract: 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.

  • Publication number: 20230355373
    Abstract: A method of implanting a prosthetic medical device at a target implantation site is provided. The method first comprises advancing a first prosthetic medical device through a subject's vasculature to a target implantation site. The first prosthetic medical device comprises a coil having an inflow end portion, an outflow end portion, and a central longitudinal axis extending from the inflow end portion to the outflow end portion. The method further comprises expanding the first prosthetic medical device from a compressed state to an expanded state to engage native vascular tissue at the target implantation site. The method subsequently comprises docking a second prosthetic medical device within the first prosthetic medical device.

  • Patent number: 11766323
    Abstract: A vascular system includes a delivery apparatus and an endovascular device. The delivery apparatus including a catheter and a control lead. The control lead extends through a lumen of the catheter and is configured to be manipulated by a user. The endovascular device is releasably coupled to the delivery apparatus and includes an implant body, a seal extending radially outwardly from the implant body, and one or more tissue engaging elements. The seal is configured to contact native vascular tissue to reduce leakage between the native vascular tissue and the implant body. The tissue engaging elements are pivotable relative to the seal from a compressed state to an expanded state. In the compressed state, the tissue engaging elements are positioned so as to disengage the native vascular tissue. In the expanded state, the tissue engaging elements extend outwardly from the seal and are configured to engage the native vascular tissue.

  • Patent number: 10568732
    Abstract: An implantable vascular device comprises an expandable and compressible implant body, a housing, a rotatable member, and a locking member. The housing is coupled to a first end portion of the implant body. The rotatable member is coupled to the housing and to a second end portion of the implant body such that rotating the rotatable member relative to the housing and the implant body expands or contracts the implant body. The locking member is coupled to the rotatable member and configured to move between an unlocked state and a locked state. In the unlocked state, the locking member allows the rotatable member to be rotated relative to the housing and the implant body. In the locked state, the locking member prevents the rotatable member from being rotated relative to the housing and the implant body.

  • Patent number: 10507097
    Abstract: Sealable and repositionable implant devices are provided with one or more improvements that increase the ability of implants such as endovascular grafts to be precisely deployed or re-deployed, with better in situ accommodation to the local anatomy of the targeted recipient anatomic site, and/or with the ability for post-deployment adjustment to accommodate anatomic changes that might compromise the efficacy of the implant. A surgical implant includes an implant body and a selectively adjustable assembly attached to the implant body, having adjustable elements, and operable to cause a configuration change in a portion of the implant body and, thereby, permit implantation of the implant body within an anatomic orifice to effect a seal therein under normal physiological conditions.

  • Patent number: 9827125
    Abstract: A sealable vascular endograft system for placement in a vascular defect includes a delivery catheter shaped to be disposed within a blood vessel. The delivery catheter includes an implant delivery catheter sheath defining an implant delivery catheter lumen and an endovascular implant removably disposed within the implant delivery catheter lumen in a compressed or folded state for delivery thereof to the vascular defect. The endovascular implant includes a tubular implant body and a sealable circumferential collar including a variable sealing device and a control lead traversing from the variable sealing device to a user and controlling variability of the variable sealing device by the user. The sealing device and the control lead cooperate to reversibly expand and contract the sealable circumferential collar to circumferentially adjust during deployment thereof to achieve a repositionable fluid-tight seal between the sealable circumferential collar and the internal walls proximal to the vascular defect.
