摘要： The apparatus of the invention includes a sensor header and a sensor cover which are coupled to a prior art diaphragm assembly. The sensor header is provided with two piezoresistive silicon membrane strain gauges. One side of both strain gauges is exposed to fluid at upstream high pressure. The other side of the first strain gauge is exposed to fluid at downstream low pressure and the other side of the second strain gauge is exposed to the atmosphere. The sensor header is provided with a first port which is fluidly coupled to the first membrane strain gauge and extends to the surface of the header at a first location. The sensor header is provided with a second port which is fluidly coupled to the second membrane strain gauge and extends to the surface of the header at a second location. The sensor cover defines two isolated annular spaces around the sensor header, a first annular space around the first location and a second annular space around the second location. The first annular space is fluidly coupled to the low pressure port of a conventional diaphragm assembly and the second annular space is fluidly coupled to the atmosphere. The method of the invention is to provide two piezoresistive membrane strain gauges, expose a first side of each strain gauge to fluid at upstream high pressure, expose the second side of the first strain gauge to fluid at downstream low pressure, and expose the second side of the second strain gauge to atmospheric pressure.

摘要： An apparatus and method that will allow for external communication, via an external programmer, for positive device identification and for retrieval of device or patient information stored by an implantable medical device with a depleted power source. The external programmer will deliver energy to a secondary power source located inside the implanted device using RF telemetry sufficient to charge up the secondary power source, e.g., a small capacitor. The capacitor will charge up immediately within milliseconds. Once the secondary power source is sufficiently charged, it can be used to power up a controller having the stored information in the implantable medical device. Once the controller is operational, the implanted device will transmit device and patient information to the external programmer via RF telemetry.

摘要： In accordance with the present invention, an implantable pump is programmed non-invasively by means of a programmer that communicates flow rate information by means of radio frequency telemetry or other methods of non-invasive telemetry. The programmer also supplies power to the implantable pump during programming. The implanted rate-adjustable pump that receives rate information and power by telemetry preferably does not include a battery or any other type of internal power supply, relying only on the energy obtained from the programmer through telemetry.

摘要： An apparatus for managing a lead of an implantable medical device includes a lead retention element and a fixation element. The lead retention element has a proximal end, a distal end, and a lumen extending from the proximal end to the distal end. The lumen is configured to slidably receive the lead. The fixation element is configured to fix the lead retention element relative to the implantable medical device in an orientation orthogonal to a lead receptacle of the device such that the proximal end of the lead retention element is closer to an opening of the lead receptacle than the distal end of the retention element. The distal end of the lead retention element is configured to firmly engage the lead to resist proximal sliding of the lead in the lumen of the retention element once the lead has been moved distally through the lumen.

摘要： An apparatus configured to be placed about an implantable medical device having a face with a geometric center offset from a center of a recharge coil of the device includes first and second opposing major exterior surfaces, and a continuous exterior side surface joining the first and second opposing major exterior surfaces. A cavity is defined between, and an opening is formed by, the first and second major surfaces and the continuous side surface. The opening is in communication with the cavity and is configured to allow the device to access the cavity. An asymmetric region, adjacent to the cavity, is formed between a portion of the first and second major surfaces and the continuous side surface. The asymmetric region is configured to shift the geometric center of the combined apparatus and device, when the device is received in the cavity, towards the center of the recharge coil.
