Patent number: 11944770Abstract: An expandable introducer sheath with an interlock dilator. The present technology provides an expandable sheath with a step feature inside its distal opening, and a dilator with an interlock that includes a catch surface configured to engage with the step feature and resist further relative movement so that the body of the dilator is prevented from exiting the distal end of the expandable sheath. This interlocking engagement may allow the dilator to be used to extend and maintain tension on the expandable sheath during insertion into a patient, and then to be retracted from the expandable sheath by pulling the dilator in the opposite direction. The present technology also provides a dilator hub with a spring mechanism configured to achieve and maintain a desired tension on the expandable sheath and to prevent overextension of the expandable sheath when the dilator is being inserted into the expandable sheath.Type: GrantFiled: April 6, 2023Date of Patent: April 2, 2024Assignee: Abiomed, Inc.Inventors: Christopher N. Korkuch, Robert Fishman, Michael Thomas Finnegan, Charles DeLorenzo, Andrew Gentile, Anne Gabrielle McLoughlin, Robert Swierczek, Matthew D'Agostino, Jonathan Barry

Publication number: 20230364393Abstract: An expandable sheath body for a sheath assembly. The sheath body has a tubular frame having a lumen therein. The frame has interstices therein. The frame is expandable to a larger diameter and contractable to a smaller diameter, and also flexible. The sheath body has an inner liner formed over a surface of the lumen defined by the tubular frame and an outer liner formed over an exterior surface of the frame. The inner liner and an inner layer of a multilayer outer liner may be made of expanded polytetrafluoroethylene. The expanded polytetrafluoroethylene may be infused with silicone oil for increased lubricity.Type: ApplicationFiled: May 10, 2023Publication date: November 16, 2023Applicant: ABIOMED, Inc.Inventors: Mithun Rajaram, Robert Fishman, Christopher N.

Publication number: 20210236783Abstract: An expandable introducer sheath with an interlock dilator. The present technology provides an expandable sheath with a step feature inside its distal opening, and a dilator with an interlock that includes a catch surface that is configured to engage with the step feature of the expandable sheath. When the step feature engages the catch surface, it resists further relative movement so that the body of the dilator is prevented from exiting the distal end of the expandable sheath. The nature of the interlocking engagement between the step feature and the catch surface allows the dilator to be used to extend and maintain tension on the expandable sheath during insertion into a patient, and then to be retracted from the expandable sheath by simply pulling the dilator in the opposite direction.Type: ApplicationFiled: February 2, 2021Publication date: August 5, 2021Applicant: ABIOMED, Inc.Inventors: Christopher N.
