  • Publication number: 20190190215
    Abstract: Distal connector assemblies that are on the distal end of medical lead extensions provide increased rigidity by including a rigid holder that contains the electrical connectors. The electrical connectors are separated within the rigid holder by insulative spacers that may be individual items or may be formed from a compliant carrier that the electrical connectors may reside within where the carrier is positioned within the rigid holder. The rigid holder may also contain a set screw block defining set screw bore or the rigid holder may include an integral portion that defines a set screw bore. The integral portion may include a slot to allow a molding pin loaded with the electrical connectors and other components to be dropped into a cavity of the rigid holder. An overmold may be present to surround the rigid body containing the electrical connectors and insulative spacers.

  • Patent number: 9220529
    Abstract: An atherectomy device is disclosed, which is rotationally driven by an electric motor. In some designs, the device includes features unavailable on gas turbine-driven systems, such as the storing in memory of low/medium/high preset rotation speeds for particular models of handle, calculations of the amount of saline left in the IV and associated warnings when it gets sufficiently low, and automatic adjustment of the IV pump rate to a predetermined or calculated level when the rotational speed of the motor is changed. The electric motor has far more rotational inertia than a comparable gas turbine, so the system includes a control mechanism that helps prevent damage from excessive torque being applied to the distal end of the drive shaft. When an obstruction at the distal end is detected, by a drop in the motor rotational speed, the motor is released and is allowed to spin freely as a flywheel.

  • Patent number: 9149627
    Abstract: Kits provide management of implantable lead extensions being implanted by providing a kit body with features that retain the extension in a configuration, with amounts being removed as needed during the implantation procedure. The kit can be present within a sterile field, and the kit body features may be arranged so that a length of a path that the extension forms is approximately equal to a length of the extension needed for the tunnel. The kit body may include features that allow the connectors of the extension as well as implantation tools to be retained within the kit body while being easily accessed when needed during the procedure. The kit may be coupled to the patient during the trial period, as the extension may have an implanted distal connector while having a proximal connector coupled to an external stimulator and while being retained on the kit body.

  • Patent number: 9075675
    Abstract: A data processing apparatus is provided for producing a randomized value. A cell in the data processing apparatus comprises a dielectric oxide layer and stress voltage circuitry is configured to apply a stress voltage across the dielectric oxide layer of the cell to cause an oxide breakdown process to occur. Oxide breakdown detection circuitry is configured to determine a current extent of the oxide breakdown process by measuring a response of the dielectric oxide layer to the stress voltage and randomized value determination circuitry is configured to determine a randomized value in dependence on the current extent of the oxide breakdown process.

  • Publication number: 20140276904
    Abstract: Tips for use on a tunneling tool provide the ability to pull an implantable medical lead extension or catheter body through a subcutaneous tunnel. The tips may include a pin with a barb, where the barb is inserted within a compliant portion of a connector body of the lead extension or a catheter body to create an interference fit that allows the connector body or catheter body to be pulled through the tunnel. The tips may include a carrier that has a cavity for the connector body, where the tunneling is performed with the carrier present on the tunneling tool. A body is positioned within the cavity of the carrier to prevent tissue from snagging on and collecting within the carrier. The body may include a tip portion that performs the tunneling function. The carrier may also provide tunneling and/or may be attached to the tunneling tool during tunneling.

  • Patent number: 8628551
    Abstract: The invention provides a rotational atherectomy system, device and method comprising a flexible, elongated, rotatable drive shaft with an abrasive section within a pre-curved section of the drive shaft. The device may further comprise a concentric or eccentric enlarged diameter section that is at least partially covered with abrasive material to comprise the abrasive section. The abrasive section may further comprise an abrasive crown or burr mounted to the drive shaft. The pre-curved drive shaft allows smaller diameter and/or massive abrasive regions to be used while sweeping larger diameters during high-speed rotation. The pre-curved region is substantially straightened for insertion into vasculature and placement adjacent stenosis by insertion of the guide wire. Removal of guide wire proximally from the pre-curved region allows the drive shaft to return to its pre-curved form for ablation. Reinsertion of the guide wire beyond the pre-curved region straightens the drive shaft for ease of removal.

  • Patent number: 8574264
    Abstract: A closure device for sealing a patent foramen ovale (PFO) in the heart includes a left atrial anchor adapted to be placed in a left atrium of the heart, a tether fixedly connected to the left atrial anchor and adapted to extend through the passageway of the PFO, a right atrial anchor adapted to be placed in a right atrium of the heart and moved along the tether, and a lock for securing the position of the right atrial anchor along the tether. The left and right atrial anchors preferably include a plurality of arms formed as loops and may include means for securing each arm in case of fracture in the loop. After the closure device is positioned, a cutting tool may sever the portion of the tether proximal of the right atrial anchor. The closure device can be retrieved during delivery, including by use of a snare catheter.
