International Classification:

H01R013/02

US Classification:

439218, 439222

Abstract:

A lead connector arrangement includes a non-cylindrically shaped connector pin coupled to a lead conductor and a connector sleeve assembly for receiving the non-cylindrically shaped connector pin. The connector sleeve assembly includes an insert with an axial bore formed therein that complements the shape of the non-cylindrical connector pin. According to one embodiment, the non-cylindrical connector pin may be provided in the form of a triangular, square, rectangular, or hexagonal shape. The axial bore has a complimentary shape to receive the connector pin. When the connector pin is threaded through the connector sleeve assembly using a pull-wire device, the pull-wire device may be unscrewed from the connector pin without causing axial rotation of the lead conductor when the connector pin is fully inserted within the axial bore.

International Classification:

A61N 1/39

US Classification:

607 5, 607 4, 607 7

Abstract:

An implantable medical device (IMD) provides for adaptive timing of the delivery of cardioversion shocks. In particular, the invention IMD provides for an adaptive cardioversion synchronization delay with respect to a cardiac event, such as a sensed P-wave or R-wave. When cardioversion with a first synchronization delay fails to terminate a tachycardia, for example, cardioversion may be attempted again with a second synchronization delay. The IMD may keep track of whether each synchronization delay is effective in terminating the tachycardia, and may employ a historically effective synchronization delay when applying cardioversion therapy to treat a subsequent tachycardia episode.

International Classification:

A61N 1/375

US Classification:

607037000

Abstract:

An improved connection system for coupling a device such as a pacemaker, cardioverter, defibrillator, nerve stimulator, muscle stimulator, implantable monitor or other medical device to a medical lead is disclosed. The connection system includes a coupling member designed to couple to the proximal end of the lead. This coupling member, which includes an inner lumen sized to form a press fit around the proximal end of the lead body, may be of a generally tubular construction. This coupling member includes connector means to enable a connector pin at the proximal end of the lead to mechanically and electrically couple to a device. The connector means may further include means for coupling both mechanically and electrically to a ring connector on the proximal end of a multi-polar lead. An insertion member may also be provided to allow the lead to be more easily inserted within the inner lumen of the coupling member.

International Classification:

US Classification:

607 20

Abstract:

A cardiac pacemaker of the type including a sensor responsive to the patient's metabolic demand for oxygenated blood and which varies the pacing rate in response to the output of the sensor. In the disclosed embodiment, a piezoelectric sensor bonded to the inside surface of the pacemaker's outer shield delivers a pulsatile sensor signal to activity circuitry, where the different peak values of the pulsatile signal correspond to different levels of patient activity. The activity circuit defines a plurality of sensor signal threshold levels. Rate control circuitry increases the pacing rate of the pacemaker by amounts corresponding to the threshold level exceeded by recent peak values of said pulsatile signal; peaks of said pulsatile signal which exceed only the lowest of the thresholds cause the smallest increase in the pacing rate, while sensor signals which exceed higher thresholds cause larger increases in the pacing rate. Several parameters, including upper and lower pacing rate limits and rate-response settings are selectable by means of an external programming device communicating with the pacemaker via radio-frequency telemetry.
