    摘要: One embodiment of the present invention relates to an implantable medical device (“IMD”) that can be programmed from one operational mode to another operational mode when in the presence of electro-magnetic interference (“EMI”). In accordance with this particular embodiment, the IMD includes a communication interface for receiving communication signals from an external device, such as a command to switch the IMD from a first operation mode to a second operation mode. The IMD further includes a processor in electrical communication with the communication interface, which is operable to switch or reprogram the IMD from the first operation mode to the second operation mode upon receiving a command to do so. In addition, the IMD includes a timer operable to measure a time period from when the processor switches the IMD to the second operation mode. In accordance with this aspect of the invention, the processor is in electrical communication with the timer, and is further operable to switch the IMD from the second operation mode back to the first operation mode when the measured time period reaches a predetermined time period.

    摘要: A medical electrical lead comprises a flexible, elongate lead body extending along a longitudinal axis and having a proximal end and a distal end. A protective distal tip structure is disposed on the distal end of the lead body. The tip structure includes a plurality of compliant projections each extending distally from the distal end of the body in the direction of the longitudinal axis. The projections are configured to contact and bear against cardiac tissue when the lead is implanted, and are deformable under the action of an axially or radially directed force. The projections optionally include a coating over a substrate. The coating can include a hydrogel material and/or a pharmaceutical agent such as a steroid for reducing inflammation at the implantation site.

    摘要: An implantable lead comprises a lead body extending from a lead proximal end portion to a lead distal end portion. In one example, the lead body may comprise a heat-formed bias portion. In another example, an outer insulator is fused to the lead body. In such an example, a lead body fusable plug may be disposed distal to at least one conductor. In another example, the lead comprises an inner boot and an outer boot fused to one another. In another example, the lead includes an atraumatic tip fused to the lead distal end portion. In another example, the lead body is reducable in size using heat shrink tubing. In yet another example, two or more lead sections may be interconnected using an outer insulator fused to the respective lead bodies. In a further example, a stiffener member is fused to the lead body adjacent a lead component.

    摘要: An implantable cardiac stimulation system having a patient warning system and an elongated electrode mounted near the can of the system for providing reliable stimulation for warning. The electrode has an extended length and a short width. The length is preferably at least double the width and more preferably at least four times the width. This extended length increases the probability that contact with the surrounding tissue will be achieved. The short width and rounded profile of the width, forming an "edge", on the other hand, increases the probability that a high enough current density will be achieved, causing stimulation to occur. The electrode may also be curved along its length, which tends to promote a "point" or small area contact between the electrode and the patient's tissue. The electrode may be mounted directly on the can or header of the cardiac stimulator or may be part of a separate pin electrode. If a pin electrode is used, a hood configuration can be used to surround at least part of the header, reducing rotation of the pin electrode. By making only a portion of the surface of the pin electrode conductive, and particularly edges or corners, an elongated electrode, as described herein, is formed which produces a higher electric current density and more efficient stimulation.
