Publication number: 20220273475Abstract: An attachment mechanism for a medical implant system may include a first part fixedly attached to a distal end of an elongate shaft, the first part having a first longitudinal lumen configured to slidably receive a release wire disposed within the elongate shaft, and a second part fixedly attached to a proximal end of a medical implant, the second part having a second longitudinal lumen configured to slidably receive the release wire. A tubular distal portion of the second part may include an engagement feature configured to non-releasably engage the second part with the medical implant.Type: ApplicationFiled: April 8, 2022Publication date: September 1, 2022Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Nicholas Lee Tassoni, Kelsey Rae Cooper, Thomas P. Jancaric, John D. Kroeger, Eric Dinges, Reggie Roth, John L. Teschendorf, David B. Morris

Patent number: 11382632Abstract: A vascular occlusion device for deployment within a lumen of a vessel may include a self-expanding frame configured to shift between a collapsed configuration and an expanded configuration, the self-expanding frame defining a perimeter of an interior space disposed within the self-expanding frame, and an occlusive membrane secured to the self-expanding frame. The occlusive membrane may include a suspended portion disposed within the self-expanding frame and spaced apart from the perimeter of the interior space.Type: GrantFiled: June 27, 2019Date of Patent: July 12, 2022Assignee: Boston Scientific Scimed, Inc.Inventors: John D. Kroeger, David Robert Wulfman, Hoi Ki Ricky Chow, Adeniyi O. Aremu, Timothy A. Ostroot, Nicholas Lee Tassoni, Daniel K. Tomaschko, David Pettijohn

Patent number: 10835259Abstract: An occlusive medical device system may include an elongate shaft having a distal strain relief portion and a lumen extending longitudinally through the elongate shaft, the elongate shaft including a plurality of retaining arms extending distally from the distal strain relief portion; an occlusive medical device including a proximal mounting portion fixed to an expandable occlusive element; and a release wire disposed within the lumen of the elongate shaft. The plurality of retaining arms may extend into the proximal mounting portion. The release wire may be configured to engage the plurality of retaining arms in a distal engagement position, thereby urging the plurality of retaining arms radially outward into releasable engagement with the proximal mounting portion. When the release wire is in a proximal released position, the plurality of retaining arms is deflectable radially inward to disengage from the proximal mounting portion.Type: GrantFiled: March 12, 2018Date of Patent: November 17, 2020Assignee: Boston Scientific Scimed, Inc.Inventors: Hoi Ki Ricky Chow, David B. Morris, John D. Kroeger

Publication number: 20190262001Abstract: An occlusive medical device such as a vascular implant includes a terminal portion including a first plurality of strut segments that are each joined together at a distal end thereof to form a closed end of the frame, an intermediate portion including a second plurality of strut segments, the second plurality of strut segments including a greater number of strut segments than the first plurality of strut segments, and a main portion including a third plurality of strut segments, the third plurality of strut segments including a greater number of strut segments than the second plurality of strut segments. The occlusive medical device may have an expanded configuration in which the second plurality of strut segments and the third plurality of strut segments together form a plurality of cells.Type: ApplicationFiled: February 20, 2019Publication date: August 29, 2019Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Thomas P.
