20120016377 | TUNNELING TOOL FOR IMPLANTABLE LEADS - A tunneling tool for creating a pathway for implanting a therapy delivery element in a living body. The tunneling tool includes a malleable elongated shaft having a distal end. A sheath having a lumen is slidably positioned over a portion of the shaft. A primary handle secured to proximal end of the shaft permits a user to advance and manipulate the shaft and the sheath in the living body. A secondary handle with an opening is slidably positioned on the shaft between the primary handle and the sheath. The opening has a diameter less than an outside diameter of a proximal end of the sheath. A locking mechanism releasably engages the secondary handle to the primary handle. The sheath is retained in a desired location within the living body by securing the secondary handle relative to the living body as the primary handle is used to remove the shaft from the sheath. | 01-19-2012 |

The conductor assembly includes an inner lumen with a diameter greater than an outside diameter of the stylet coil. Axial elongation of the elongated lead body reduces the inner diameter of the conductor assembly. A low durometer insulator extends around the conductor assembly. A stylet sized to slide freely within the stylet coil lumen is provided for use during implantation of the therapy delivery element into the living body. | 09-13-2012 |
20120232627 | PRE-SUTURED ANCHOR FOR IMPLANTABLE LEADS - A pre-sutured anchor including a deformable anchor sleeve with a lumen sized to receive the therapy delivery element. An outer surface of the anchor sleeve including one or more annular compression grooves oriented generally co-axial to the lumen. At least one compression member is located in a compression groove in an open configuration. The compression member includes at least one stop. A suture material pre-tied in a self-locking compression knot extends around each compression member. The suture material includes distal ends adapted to receive a tension force that is transmitted as a radial compression force to deform the compression members and substantially engage the stop in a compressed configuration. The anchor sleeve compressively engages the therapy delivery element in the compressed configuration. | 09-13-2012 |
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 |
20130053864 | LEAD BODY WITH INNER AND OUTER CO-AXIAL COILS - A biomedical conductor assembly adapted for at least partial insertion in a living body.
