  • Patent number: 7448122
    Abstract: A method of making a polymeric tubular layer of an expandable medical device or component, in which the polymeric tubular layer is longitudinally compressed by longitudinally stretching a tube over the polymeric tubular layer and releasing the tube from the stretched configuration so that the length of the tube decreases and thereby decreases the length of the polymeric tubular layer. The resulting compressed polymeric tubular layer can be used in a variety of expandable medical devices and in one presently preferred embodiment it forms a catheter balloon having at least one layer.

  • Publication number: 20070257011
    Abstract: The variability of immersion processes for treatment of semiconductor devices can be significantly lowered by initiating the termination of a treatment process according to a predetermined treatment termination protocol in a manner that takes into account the contribution of, in particular, the treatment that is carried out during the period of time in the treatment process in which the treatment process is being terminated. In a preferred embodiment, conditions that indicate the progress of the treatment on a real time basis are monitored, and the timing of the initiation of the termination process is additionally based on the calculated amount of treatment and treatment rate of the process in progress.

  • Publication number: 20060275142
    Abstract: A method is disclosed for determining the operating condition of a medical pump based on data derived from a pressure sensor and a position sensor. The pressure sensor generates pressure data by sensing the force on the pumping element. The position sensor generates position data by tracking the pumping cycle and determining the position of the pumping element. The pump pressure data and pump position data are processed and the calculated results compared with a pre-determined threshold value to determine the operating condition of the pump. The three main types of operating conditions of concern are the following: normal condition, where liquid is present and no leaks exist in pumping chamber; leak condition, where liquid is present but a leak exists in the pumping chamber; and air stroke condition, where the chamber contains some air.

  • Publication number: 20060020303
    Abstract: A medical system and method of establishing communication between a plurality of implantable medical devices and an external device. An identification command is sent transcutaneously to at least one of the plurality of implantable medical devices. The plurality of implantable medical devices respond to the identification command with an uplink response in one of a plurality of uplink time slots. The external device receives the uplink response from each of at least one of the plurality of implanted medical devices. The external device establishes transcutaneous communication to a selected one of the plurality of implanted medical devices based, at least in part, upon a signal strength of said uplink response of at least one of said plurality of implanted medical devices.

  • Publication number: 20050075697
    Abstract: A transcutaneous energy transfer system, transcutaneous charging system, external power source, external charger and methods of transcutaneous energy transfer and charging for an implantable medical device and an external power source/charger. The implantable medical device has a secondary coil adapted to be inductively energized by an external primary coil at a carrier frequency. The external power source/charger has a primary coil and circuitry capable of inductively energizing the secondary coil by driving the primary coil at a carrier frequency adjusted to the resonant frequency to match a resonant frequency of the tuned inductive charging circuit, to minimize the impedance of the tuned inductive charging circuit or to increase the efficiency of energy transfer.

  • Publication number: 20030114744
    Abstract: An intravascular imaging guidewire which can accomplish longitudinal translation of an imaging plane allowing imaging, by acoustic or light energy, of an axial length of a region of interest without moving the guidewire. The imaging guidewire comprises a body in the form of a flexible elongate tubular member. An elongate flexible imaging core is slidably received within the body. The imaging core includes a shaft having an imaging device mounted on its distal end. The body and the imaging core are cooperatively constructed to enable axial translation of the imaging core and imaging device relative to the body. The body has a transparent distal portion extending an axial length over which axially translatable imaging may be performed. The imaging guidewire has a maximum diameter over its entire length sized to be received within a guidewire lumen of an intravascular catheter.
