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.

Abstract: Implantable medical leads and/or lead extensions include a band that encapsulates a portion of conductors of the lead and/or lead extension. The band may be reflowed in order to provide the encapsulation of the conductors. The band may further be used to create a seal together with the surrounding lead body and an additional object such as a stiffener rod, stylet tube, and/or molding stylet, to allow a proximal area of a lumen of the lead body to be injection molded while prevent the injection molding material from proceeding past the band. When a stiffener rod is present in a proximal area of the lead and/or lead extension, additional stiffness is provided to the lead body to resist buckling of the lead body during insertion of the proximal end. The band may be bonded to the stiffener rod to fix the position of the stiffener rod relative to the conductors.

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.

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.

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.

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.
