Abstract: A catheter assembly includes a cap and a spring-biased tethering member coupled thereto. The cap includes first and second portions, and a transition zone extending therebetween. A girth of the first portion is sized to fit within a distal-most opening of the catheter assembly; and a girth of the second portion tapers from a first size at the transition zone, which is too large to fit within the distal-most opening, to a smaller size at a distal end of the cap. The spring-biased tethering member holds the cap in open and closed positions, when the cap first portion extends within the distal-most opening, and when the cap is separated from the distal-most opening, respectively. At the closed position, the first portion is approximately concentric with the distal-most opening, and at the open position, an entirety of the cap is laterally offset from the distal-most opening.

Abstract: Method and systems of determining adequacy of fixation of a medical lead type having a fixation helix are disclosed. The lead of the medical lead type is placed at a desired location within a patient's body and the fixation helix is screwed into tissue at that location. One or more parameters, associated with the lead, are measured at the location. Based upon the measured one or more parameters, determining a number of turns that the helix is embedded into the tissue at the location.

Abstract: An implantable device system for delivering electrical stimulation pulses to a patient's body includes a pulse delivery device having a piezoelectric element that is enclosed by a housing and produces voltage signals delivered to the patient's body in response to receiving ultrasound energy. The pulse delivery device includes a circuit having a rate limiter configured to filter voltage signals produced by the piezoelectric element a rate faster than a maximum stimulation rate.

Abstract: An implantable medical device system is configured to deliver cardiac pacing by receiving a cardiac electrical signal by sensing circuitry of a first device via a plurality of sensing electrodes, identifying by a control module of the first device a first cardiac event from the cardiac electrical signal, setting a first pacing interval in response to identifying the first cardiac event, controlling a power transmitter of the first device to transmit power upon expiration of the first pacing interval, receiving the transmitted power by a power receiver of a second device; and delivering at least a portion of the received power to a patient's heart via a first pacing electrode pair of the second device coupled to the power receiver.
