Patent number: 11925334Abstract: Methods and devices for separating an implanted object, such as a pacemaker lead, from tissue surrounding such object in a patient's vasculature system. Specifically, the tissue separating device includes a handle, an elongate sheath and a circular cutting blade that may extend from the distal end of the sheath upon actuating the handle. The elongate sheath, particularly its distal end, includes a non-uniform wall thickness having one or more thicker portions in the outer sheath, particularly the outer cam member, and/or one or more thicker portions in an inner member disposed radially inward of the blade.Type: GrantFiled: November 30, 2020Date of Patent: March 12, 2024Assignee: SPECTRANETICS LLCInventors: Kenneth P. Grace, Bruce A. Hoo

Patent number: 11160579Abstract: Devices for removing implanted objects from body vessels are provided. A device includes a sheath assembly having a cutting tip. The cutting tip includes a cutting surface that is adapted to cut tissue coupled to an implanted object as the cutting tip rotates. The sheath assembly further includes an outer shield carried outside of the cutting tip. The outer shield includes a distal opening, and the outer shield is translatable relative to the cutting tip from a first position to a second position and vice versa. In the first position the cutting surface of the cutting tip is disposed within the outer shield, and in the second position the cutting tip extends through the distal opening and the cutting surface is at least partially disposed outside of the outer shield.Type: GrantFiled: September 10, 2018Date of Patent: November 2, 2021Assignee: SPECTRANETICS LLCInventors: Kenneth P. Grace, Weston H. Lee, Brian E. Kagarise, Bruce A. Hoo, Robert Carver, Peter Wilbur Gleason, Phillip Charles Halbert

Patent number: 10842532Abstract: Methods and devices for separating an implanted object, such as a pacemaker lead, from tissue surrounding such object in a patient's vasculature system. Specifically, the surgical device includes a handle, an elongate inner sheath and a circular cutting blade that extends from the distal end of the sheath upon actuating the handle. The circular cutting blade is configured to engage the tissue surrounding an implanted lead and cut such tissue in a coring fashion as the surgical device translates along the length of the lead, thereby allowing the lead, as well as any tissue remaining attached to the lead, to enter the device's elongate shaft. The surgical device has a barrel cam cylinder in the handle assembly that imparts rotation of the blade and a separate cam mechanism in the tip of outer sheath assembly that imparts and controls the extension and retraction of the blade.Type: GrantFiled: February 24, 2017Date of Patent: November 24, 2020Assignee: SPECTRANETICS LLCInventors: Kenneth P.

Publication number: 20070106364Abstract: An intraluminal medical device delivery system that distributes forces more uniformly across an intraluminal medical device during loading and delivery of the device to an intended treatment site. A support member provided on an inner member of a catheter delivery system helps to more uniformly distribute forces across the device by crimping the device over the support member so as to place the support member in a mechanically compressed state during delivery of the device to the intended treatment site. The support member is preferably comprised of a material having a modulus of elasticity that increases when the material is compressed. The mechanical nature of the support member provides increased stability to the device during loading and delivery thereof without providing heat or other preformed or additional mechanical members to the support member. Repositioning of the device is available due to the stability of the device when mounted on the support member.Type: ApplicationFiled: November 9, 2005Publication date: May 10, 2007Inventors: Jon Buzzard, Bruce Hoo, Karen Jackson, Francisco Valdes, Christopher Widenhouse
