1. An implantable cardiac pacing system comprising:
- a housing configured to be implanted substantially within an anterior mediastinum of a patient, wherein the anterior mediastinum represents a non-vascular, extra-pericardial location;
one or more anchoring mechanisms positioned along a length of the housing, wherein the one or more anchoring mechanisms are configured to anchor the housing within the anterior mediastinum of the patient such that the housing is physically isolated from a pericardium of the patient, wherein the one or more anchoring mechanisms comprises one or more tines extending from the housing, and wherein the one or more anchoring mechanisms are configured to affix the housing to loose connective tissue or other structures of the anterior mediastinum;
a first electrode on the housing;
a second electrode on the housing; and
a pulse generator within the housing and electrically coupled to the first electrode and the second electrode, wherein the pulse generator is configured to deliver pacing pulses to a heart of the patient via a therapy vector formed between the first and second electrodes.

Abstract
Implantable leadless cardiac pacing systems and methods for providing substernal pacing using the leadless cardiac pacing systems are described. In one embodiment, an implantable leadless cardiac pacing system includes a housing, a first electrode on the housing, a second electrode on the housing, and a pulse generator within the housing and electrically coupled to the first electrode and the second electrode. The housing is implanted substantially within an anterior mediastinum of a patient and the pulse generator is configured to deliver pacing pulses to a heart of the patient via a therapy vector formed between the first and second electrodes.

19. A method comprising:
-
providing a leadless implantable pulse generator (IPG) substantially within an anterior mediastinum of a patient, the leadless IPG including a housing configured to be implanted substantially within the anterior mediastinum, wherein the anterior mediastinum represents a non-vascular, extra-pericardial location, one or more anchoring mechanisms positioned along a length of the housing, wherein the one or more anchoring mechanisms are configured to anchor the housing within the anterior mediastinum of the patient such that the housing is physically isolated from a pericardium of the patient, wherein the one or more anchoring mechanisms comprises one or more tines extending from the housing, and wherein the one or more anchoring mechanisms are configured to affix the housing to loose connective tissue or other structures of the anterior mediastinum, a first electrode on the housing, a second electrode on the housing, and a pulse generator within the housing and electrically coupled to the first electrode and the second electrode; generating one or more stimulation pulses with the implantable pulse generator; and delivering the one or more stimulation pulses to a heart of the patient via the first and second electrode of the leadless IPG implanted substantially within the anterior mediastinum. - View Dependent Claims (20, 21, 22, 23, 24, 25)
