LEADLESS PACING SYSTEM INCLUDING SENSING EXTENSION

摘要

A leadless pacing system includes a leadless pacing device and a sensing extension extending from a housing of the leadless pacing device. The sensing extension includes one or more electrodes with which the leadless pacing device may sense electrical cardiac activity. The one or more electrodes of the sensing extension may be carried by a self-supporting body that is configured to passively position the one or more electrodes proximate or within a chamber of the heart other than the chamber in which the LPD is implanted.

1. A system comprising:
a leadless pacing device comprising:
a stimulation module configured to generate pacing pulses;a sensing module;a processing module;a housing configured to be implanted within a chamber of a heart of a patient, wherein the housing encloses the stimulation module, the sensing module, and the processing module; anda first electrode electrically coupled to the sensing module and the stimulation module; and an extension extending from the housing and comprising:
a body mechanically connected to the housing and comprising a conductor electrically connected to at least one of the sensing module or the stimulation module;a second electrode carried by the body and electrically connected to the conductor; andan eyelet at a proximal end of the extension.
