20120330354 | MULTI DUROMETER REINFORCED SUTURE SLEEVE - Suture anchors for securing therapy delivery elements, such as stimulation leads or catheters, within a living body. The suture anchor includes an inner sleeve constructed with an inner layer of a softer, more pliable material that easily conforms to the therapy delivery element to reduce slippage and an outer layer constructed from a harder, stiffer durometer material that protects the therapy delivery elements from damage due to over-tightening the tie down sutures. A suture material located in the suture groove is tensioned to apply a radial compressive force. The reinforcing structure spreads the radial compressive force along a greater surface area of the therapy delivery element. | 12-27-2012 |
20120330355 | MULTI-DUROMETER REINFORCED SUTURE SLEEVE - A suture anchor for securing a therapy delivery element in a desired location within a living body using a suture material. The suture anchor includes an inner sleeve with a primary lumen sized to receive the therapy delivery element. The inner sleeve includes a compliant material having a first durometer. An anchor body extends around at least a portion of the inner sleeve and includes a portion of the primary lumen. The anchor body includes a compliant material having a second durometer less than the first durometer. At least one exterior suture groove is located on the anchor body to receive the suture material. The exterior suture groove extends substantially to the inner sleeve so the suture material engages directly with the inner sleeve. | 12-27-2012 |
20130053865 | ADJUSTABLE WIRE LENGTH STYLET HANDLE - A stylet-lead assembly including a therapy delivery element and a stylet. The therapy delivery element includes a proximal end with a plurality of electrical contacts adapted to electrically couple with an implantable pulse generator, a distal end with a plurality of electrodes electrically coupled to the electrical contacts, and a lumen having a lumen length extending from the proximal end to almost the distal end. The stylet handle includes a locking insert has a first channel adapted to receive the proximal end of the stylet wire. The portion of the stylet wire extending beyond a proximal end of the locking insert includes at least one bend. A stylet handle has an opening at a distal end adapted to compressively engage the proximal end of the stylet wire to the locking insert, such that an exposed portion of the stylet wire measured from the distal end of the stylet wire to a distal end of the locking insert generally comprises the lumen length. | 02-28-2013 |
20130053927 | LEAD IDENTIFICATION SYSTEM - A lead identification system for tracking a plurality of neurostimulation leads during implantation in a patient, and a method of using the same. The lead identification system includes a plurality of lead indicators each adapted to attach to one of a plurality of epidural needles to identify the leads. At least one clip adapted to releasably attach to proximal ends of the leads is provided with corresponding lead indicators. The trial cable for conducting trial stimulation includes connectors with corresponding lead indicators. A plurality of lead indicator stylets are provided for insertion into lumens at the proximal ends of the leads. The pulse generator also has connectors with corresponding lead indicators. The various lead indicators permit a surgeon to track a particular lead to the corresponding connectors on the pulse generator. | 02-28-2013 |
20140005675 | LEAD POSITIONING AND FINNED FIXATION SYSTEM | 01-02-2014 |
20140046413 | LEAD POSITIONING AND FIXATION SYSTEM - A therapy assembly configured for at least partial insertion in a living body. A plurality of fixation structures are disposed radially around the therapy delivery element proximate the electrodes. The fixation structures include wires having a diameter in a range between about 0.004 inches and about 0.020 inches. The wires have a first end attached to the therapy delivery element and a second end attached to a sliding member configured to slide along the therapy delivery element. The fixation structures are configured to collapse inward to a collapsed configuration when inserted into a lumen of an introducer and to deploy to a deployed configuration when the introducer is retracted. A fitting is located at proximal end of the introducer that releasably locks the therapy delivery element to the introducer, such that torque applied to the fitting is substantially transmitted to the distal end of the therapy assembly. | 02-13-2014 |
20140350655 | LEAD IDENTIFICATION SYSTEM - In some examples, a lead identification system includes a first set of first lead indicators and a second set of second lead indicators. Each of the first lead indicators is configured to removably attach to at least one of a first therapy delivery element, a first epidural needle, or a first connector to uniquely identify at least one of the first therapy delivery element, the first epidural needle, or the first connector during implantation of the first therapy delivery element in the patient. Each of the second lead indicators is configured to removably attach to at least one of a second therapy delivery element, a second epidural needle, or a second connector to uniquely identify at least one of the second therapy delivery element, the second epidural needle, or the second connector during implantation of the second therapy delivery element in the patient. | 11-27-2014 |
20150238752 | LEAD POSITIONING AND FINNED FIXATION SYSTEM - A therapy assembly configured for at least partial insertion in a living body. At least one fixation structure is attached to the therapy delivery element proximate the electrodes. The fixation structure is configured to collapse radially inward and wrap circumferentially around the therapy delivery element to a collapsed configuration when inserted into a lumen of an introducer. The fixation structures deploy to a deployed configuration when the introducer is retracted. The fixation structure includes major surfaces generally parallel with, and extending radially outward from, a central axis of the therapy delivery element, proximal edge surface oriented toward the proximal end, and a distal edge surface oriented toward the distal end. The proximal and distal edge surfaces provide generally symmetrical resistance to displacement of the therapy delivery element within the living body in either a proximal direction or a distal direction along the central axis. | 08-27-2015 |
