  • Publication number: 20180078772
    Abstract: A guiding catheter and method of its use are presented wherein the catheter includes an elongate catheter shaft having a proximal region and a distal region and a length. The shaft defines a distal region and includes a distal tip. The distal region defines an arc of approximately 180 degrees and having a radius of 0.3 inches to 0.6 inches. The distal tip forms a half turn of a left-hand helix having a pitch of 0 inches to 0.4 inches. The unique shape of the distal region allows the distal tip be perpendicularly aligned with the septal wall of the right atrium at the His bundle location when the catheter is advanced therein.

  • Patent number: 9427575
    Abstract: An extendable medical lead comprises a lead body and a sheath defining a cavity that encloses a length of the lead body. The length of the lead body enclosed within the sheath may be coiled or otherwise gathered such that when extended, the length of the enclosed section of the lead body is greater than the length of the sheath. The sheath may include a seal to help prevent contaminant entry into the cavity in order to help reduce tissue in growth around the length of the lead body disposed within the sheath. A portion of the length of the lead body enclosed within the sheath exits the cavity through an aperture defined by the seal when a tensile force is applied to the lead body.

  • Patent number: 8666511
    Abstract: This disclosure describes an implantable medical lead, and method of making such a lead, that reduces the undesirable effects the fields generated by an MRI device may have on the implantable medical lead and the implantable medical device. The implantable medical lead has a proximal end configured to connect to an implantable medical device and a distal end. The lead also includes at least one electrode located near the distal end and at least one coiled conductor that extends along a length of the lead from the proximal end to a respective electrode. The lead further includes an outer jacket that is configured to only partially extend between turns of one or more of the coiled conductors.

  • Publication number: 20140031907
    Abstract: An implantable medical lead body has a proximal end and a distal end. The lead body includes an inner tubing defining a lumen and formed of one or more non-conductive materials, a plurality of coiled conductors wound around the inner tubing, and an outer jacket extending over the plurality of coiled conductors. The inner tubing of the lead body may be design with a reduced coefficient of friction. For example, an inner surface of the inner tubing may have a lower coefficient of friction than an outer surface of the inner tubing. In another example, the inner tubing may be formed of a polymer having a surface modified to provide a reduced coefficient of friction.

  • Patent number: 7177704
    Abstract: The present invention provides for a method and apparatus providing pacing to improve the hemodynamics of the heart for patients with AV nodal block, right/left bundle branch block, and heart failure. A lead body having at least one conductor with an insulative sleeve is introduced into the right atrium of a heart. A partially masked helical electrode connected to the conductor is then secured preferably into the atrial aspect of the atrioventricular septum. The electrical conductor is then rotated such that an unmasked portion of the electrode is moved to a depth within the heart tissue substantially near the heart's intrinsic conduction system. This method and apparatus allow pacing in a natural manner via low power stimulation of the heart's intrinsic conduction system.

  • Patent number: 7092764
    Abstract: The present invention includes a “Z shaped” configuration for a pair of internal windings of a fiber core of a medical electrical lead which can be configured as or windings to provide counter-rotation an implanted cardiac lead. When fully assembled and implanted within a patient, a screw-type active fixation electrode, such as a helical electrode, electrically couples to a coil conductor and mechanically couples to a loop formed at an end of the Z-shaped braided fiber. To remove the lead, an axial traction force is applied and as the Z-shaped braids begin to unwind rotational forces operate to unscrew the helical electrode. A lead constructed according to the present invention rotates counterclockwise and thus essentially unscrews the active fixation electrode.
