Abstract
A leadless pacing device may include a housing having a proximal end and a distal end, and a set of one or more electrodes supported by the housing. The housing may include a first a distal extension extending distally from the distal end thereof. One or more electrodes may be supported by the distal extension. The leadless pacing device may be releasably coupled to an expandable anchor mechanism.
Claims20
A leadless cardiac device configured for deployment within a patient's vasculature at a location near the patient's heart, the leadless cardiac device comprising:
- an elongated housing configured to be positioned within the patient's vasculature proximate the patient's heart, the elongated housing having a proximal end and a distal end;
- a power source disposed within the elongated housing;
- circuitry disposed within the elongated housing and operatively coupled to the power source, the circuitry configured to pace the patient's heart and/or sense electrical activity of the patient's heart;
- a first electrode fixed relative to the elongated housing and operatively coupled to the circuitry;
- a second electrode fixed relative to the elongated housing and operatively coupled to the circuitry, the second electrode spaced from the first electrode and positioned along a side wall of the elongated housing;
- a distal extension extending distally from the distal end of the elongated housing, the distal extension including at least one electrode positioned near a distal end thereof and operatively coupled to the circuitry;
- and
- an expandable anchoring mechanism releasably coupled to the elongated housing, the expandable anchoring mechanism having a collapsed configuration for delivery and an expanded configuration that locates the leadless cardiac device within the patient's vasculature.
A leadless cardiac device configured for deployment within a patient's vasculature at a location near the patient's heart, the leadless cardiac device comprising:
