Publication number: 20140277037Abstract: 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 circular cutting blade is configured to engage the tissue surrounding an implanted lead and cut such tissue in a coring fashion as the 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 tissue separating device includes a cam mechanism at the distal portion of the sheath that allows the user of the device to more accurately control the extension and rotation of the cutting blade upon being actuated by the handle.Type: ApplicationFiled: March 15, 2013Publication date: September 18, 2014Applicant: The Spectranetics CorporationInventors: Dustin L.

Patent number: 8834501Abstract: An endoscopic scissor instrument includes an elongate hollow member, an actuator that moves axially through the hollow member, and first and second scissor blades with respective cutting surfaces. At least one of the scissor blades is rotatably coupled to the hollow member adjacent its distal end. At least one of the scissor blades includes a base supporting a resilient leaf-spring portion that includes a respective cutting edge. The resilient leaf-spring portion extends from the base in a cantilevered arrangement and generates a spring force acting on the respective cutting edge such that in a loaded state there is an automatic preload force imparted between the cutting edges of the scissor blades to maintain a consistent and continuous mating force between the two opposed sharpened cutting edges preferably over the complete range of rotational movement of the scissor blades.Type: GrantFiled: November 18, 2011Date of Patent: September 16, 2014Assignee: Slater Endoscopy, LLCInventor: Charles R.
