Implantable medical device system having implantable cardioverter-defibrillator (ICD) system and substernal leadless pacing device
First Claim
1. An implantable cardiac system comprising:
- an implantable cardioverter-defibrillator (ICD) system comprising;
an ICD configured to be implanted subcutaneously in a patient; and
an implantable defibrillation lead having a proximal portion coupled to the ICD and a distal portion having a defibrillation electrode configured to deliver a defibrillation shock to a heart of the patient; and
an implantable leadless pacing device communicatively coupled to the ICD, the leadless pacing device including;
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,wherein the housing is configured to be implanted substantially within an anterior mediastinum of the 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.

Abstract
Implantable cardiac systems and methods for providing substernal pacing in an ICD system are described. In one example, an implantable cardiac system comprises an ICD system and an implantable leadless pacing device (LPD) communicatively coupled to the ICD system. The ICD system includes an ICD and an implantable defibrillation lead having a proximal portion coupled to the ICD and a distal portion having a defibrillation electrode configured to deliver a defibrillation shock to a heart of the patient. The LPD 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 of the LPD is implanted substantially within an anterior mediastinum of the patient and the pulse generator is configured to deliver pacing pulses to a heart via the first and second electrodes.
