Patent number: 10258792Abstract: In some embodiments, without limitation, the invention comprises an apparatus for cutting an endocardial lead within a patient. The apparatus comprises a generally flexible tubular member having a proximal end and distal end. At least one blade or cutting surface is affixed to the distal end of the tubular member. The apparatus optionally includes an adjustment mechanism adapted to adjust the blade or cutting surface between an extended position and a retracted position. The blade or cutting surface engages the endocardial lead to cut the lead. Various embodiments include a v-shaped groove defining the cutting surfaces. Other embodiments may comprise a rotatable blade of an inner shaft rotating within the tubular member and cutting the lead received within the v-shaped groove, and blades or cutting surfaces functioning like guillotines or scissors retracting into a distal end of the tubular member.Type: GrantFiled: July 25, 2016Date of Patent: April 16, 2019Assignee: The Spectranetics CorporationInventors: Andrew Archuleta, David Atwell, Kenneth D. Harlan, Thomas E. Plasket, Kevin D. Taylor

Patent number: 8428747Abstract: A lead locking device has a lead insertion member having a proximal end and a distal end and has a lead engaging assembly. The lead insertion member defines a lumen extending along a longitudinal axis between the distal end and the proximal end of the lead engaging assembly. A mandrel disposed in the lumen of the lead engaging assembly extends along substantially the entire length of the lumen and protrudes beyond the most proximal end of the lead insertion member. The mandrel includes a distal portion in slidable contact with at least a portion of the lead engaging assembly. The lead engaging assembly has a first configuration while being inserted into a lumen of a lead and a second configuration while engaging the lead from within the lumen of the lead. The lead engaging member has at least two expansion jaws that, in the first configuration, define a substantially cylindrical body.Type: GrantFiled: June 25, 2004Date of Patent: April 23, 2013Assignee: The Spectranetics Corp.Inventors: Michael Sean Coe, Kenneth D. Harlan, Cesar Diaz, Thomas E. Plasket

Patent number: 7499756Abstract: A lead locking device has a lead engaging member with a mandrel extending along a lumen and attached to the distal end of the lead engaging member such that it extends beyond the proximal end of the lead engaging member. The lead locking device also has a loop handle attached to the proximal end of the mandrel. The lead engaging member has a first configuration which is narrower than a second configuration and is sufficiently long to extend along substantially the entire length of a lead to be removed from a patient's body. At the distal end, a spring coil is disposed around a tapered section of the mandrel to improve tracking of the lead locking device through the inner lumen of a pacing or defibrillator lead.Type: GrantFiled: February 17, 2005Date of Patent: March 3, 2009Assignee: SpectraneticsInventors: Wade A. Bowe, Kevin D. Taylor, Michael Sean Coe, Kenneth D. Harlan, Brian Kagarise, Thomas E. Plasket
