  • Patent number: 10617402
    Abstract: Methods and tool kits for implanting a lead subcutaneously. Examples include tool kits and methods for establishing first and second subcutaneous tunnels at an angle relative to one another to facilitate introduction of a lead to the subcutaneous space. In an example, a first insertion tool is used to establish a first subcutaneous tunnel, and a second insertion tool, with or without the use of a blunt dissector, sheath, guidewire, or steering mechanism, is used to initiate or form the second subcutaneous tunnel. Such methods and tool kits may reduce the number of incisions needed to implant a subcutaneous lead along a subcutaneous path having a curve therein.

  • Patent number: 10555726
    Abstract: Various aspects describe a lead delivery system for percutaneous introduction of a lead to a stimulation site near a neural target, such as the vagus nerve for nerve stimulation. The lead delivery system may include a needle assembly having a needle adapted to cut through tissue and provide initial access into the carotid sheath. The needle may be retracted into the lead delivery system to prevent cutting structures in the carotid sheath. The lead delivery system may also include a dilator assembly having one or more dilators to dilate a path to the stimulation site. The lead delivery system may further comprise a dilator assembly including a retractable needle adapted to cut through tissue. One or more locating elements, alternatively or in addition to one or more imaging elements, may be used on individual components of the lead delivery system for enhanced trackability and locatability within the body.

  • Patent number: 10265097
    Abstract: The disclosure relates to a needle assembly for delivering a lead and methods of use. The needle assembly is configured to cut tissue and reduce the potential for cutting vulnerable bodily structures. The needle assembly includes an outer needle with a blunt tip and an inner needle with a sharp tip. The outer needle may be curved, and the inner needle may be curved. When the inner needle is rotated with respect to the outer needle, the inner needle protracts or retracts with respect to the outer needle. A stopping feature on the needle assembly may be included to resist over-rotation or over-extension. The needle assembly provides an initial path that may be further dilated for delivering a lead, such as a vagus nerve stimulation lead to a target site. The target site may be electrically tested with some embodiments.

  • Patent number: 9579501
    Abstract: Various embodiments concern implanting a lead to directly stimulate the bundle of His. Various embodiments can include introducing a curve of an outer guide catheter into the right ventricle, extending a curve of an inner guide catheter from a lumen of the outer guide catheter, extending a fixation element on a distal tip of an anchor wire from a lumen the inner guide catheter, and anchoring the anchor wire to target tissue within the right ventricle, the target tissue along the septal wall and proximate the tricuspid valve and the bundle of His. A distal tip of an implantable lead with a lumen can then be advanced over the anchor wire to the target tissue as the anchor wire guides the distal tip of the lead to the target tissue.

  • Publication number: 20170021159
    Abstract: New methods for implanting a cardiac therapy system include implanting a lead of the system substernally anterior of the heart without attaching to the myocardium or pericardium. An illustration includes placement of an anchor beneath the sternum in the vicinity of one of the sternal angle, a location superior of the ventricles, the area bounded by the 2nd or 3rd ribs, and level with the aortic arch. A tension element or tether is attached to the anchor and a lead is introduced over the tension element or tether and secured in a desired position relative to the anchor. Other examples also include implantation, substernally, of a lead without the use of a pre-tunneling tool or sheath over the lead itself, for example by using an advancing tool for pushing the lead into position.

  • Patent number: 8996114
    Abstract: A lead assembly for an implantable medical device includes a lead body having a proximal end, a distal end, and a longitudinal axis that extends between the proximal end and distal end. The lead assembly also includes a strain relief tube that surrounds a portion of the lead body. The strain relief tube includes a flexible material configured to include contours such that the portion of the lead body surrounded by the strain relief tube maintains a formed shape that varies from the longitudinal axis of the lead body. The contours vary in response to forces on the lead body to prevent strain at the distal end of the lead body.

  • Patent number: 8983626
    Abstract: Various embodiments concern wrapping a stimulation cuff around a nerve. The cuff can comprise a main body and at least one electrode. The main body can comprise an inner tab, an outer tab, and an intermediate portion extending between the inner tab and the outer tab, the at least one electrode disposed on the intermediate portion, the main body biased such that the cuff assumes the coiled arrangement. The cuff can be uncoiled by pulling on a first elongate element attached to a first tubular member, the first tubular member encircled within the cuff. The nerve can be engaged with an inner surface of the main body along the intermediate portion while the inner tab is releaseably attached to the first elongate element. The first elongate element can be released to allow the cuff to wrap around the nerve.

    Abstract: A method for allowing cardiac signals to be sensed and pacing pulse vectors to be delivered between two or more electrodes. In one embodiment, cardiac signals are sensed and pacing pulse vectors are delivered between at least one of a first left ventricular electrode and a second left ventricular electrode. Alternatively, cardiac signals are sensed and pacing pulse vectors are delivered between different combinations of the first and second left ventricular electrodes and a first supraventricular electrode. In addition, cardiac signals are sensed and pacing pulse vectors are delivered between different combinations of the first and second left ventricular electrode, the first supraventricular electrode and a conductive housing. In an additional embodiment, a first right ventricular electrode is used to sense cardiac signals and provide pacing pulses with different combinations of the first and second left ventricular electrodes, the first supraventricular electrode and the housing.
