Patent number: 12588918Abstract: Inverting tube apparatuses and methods of using same for removing large amounts of material from a body lumen. The apparatuses and methods described herein may use a depot for holding, in a compressed configuration, a length of the flexible tube configured to invert over the distal end of an inversion support catheter to capture material within a body lumen. The depot is configured to facilitate the release of the flexible tube with a low release force, and in a manner that prevents snagging or binding of the flexible tube either on the body of the catheter or when rolling and inverting into the inversion support catheter.Type: GrantFiled: July 18, 2022Date of Patent: March 31, 2026Assignee: STRYKER CORPORATIONInventors: Michael P.

Patent number: 12478770Abstract: A micropuncture kit for direct access of a surgically exposed vessel using direct visual guidance includes a micropuncture access needle having a proximal hub coupled to an elongate shaft defining an inner lumen and a visible depth indicator positioned on the elongate shaft a distance away from a distal tip of the elongate shaft. The kit includes an access guidewire sized to be received through the inner lumen of the micropuncture access needle and a microaccess cannula having an elongate body defining an inner lumen and a plurality of visible depth indicators formed on the elongate body. The guidewire includes a distal tip and at least one visible depth indicator positioned on the access guidewire a distance away from the distal tip of the guidewire. Each of the plurality of visible depth indicators identifies a distance from a distal tip of the cannula. Related systems, devices and methods are provided.Type: GrantFiled: June 28, 2024Date of Patent: November 25, 2025Assignee: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Stewart M.

Patent number: 12383275Abstract: Vaso-occlusive apparatuses, including implants, and methods of using them to treat aneurysms. The vaso-occlusive implants described herein include one or more soft and expandable braided member coupled to a pushable member such as a coil that maybe inserted and retrieved from within an aneurism using a delivery catheter as well as a friction element between the soft braided member and the coil. The friction element allows the relatively soft and elongate implant to be pushed out of a cannula without binding up within the cannula.Type: GrantFiled: February 22, 2022Date of Patent: August 12, 2025Assignee: Stryker European Operations Holdings, LLCInventors: Michael P.

Patent number: 12285578Abstract: Disclosed is an arterial access sheath for introducing an interventional device into an artery. The arterial access sheath includes an elongated body sized and shaped to be transcervically introduced into a common carotid artery at an access location in the neck and an internal lumen in the elongated body having a proximal opening in a proximal region of the elongated body and a distal opening in a distal region of the elongated body. The internal lumen provides a passageway for introducing an interventional device into the common carotid artery when the elongated body is positioned in the common carotid artery. The elongated body has a proximal section and a distalmost section that is more flexible than the proximal section. A ratio of an entire length of the distalmost section to an overall length of the sheath body is one tenth to one half the overall length of the sheath body.Type: GrantFiled: August 11, 2023Date of Patent: April 29, 2025Assignee: Silk Road Medical, Inc.Inventors: Stewart M. Kume, Michi E. Garrison, Michael P. Wallace, Herbert Mendoza, Marlon Moreno
