A system and method are provided for managing atrial-ventricular (AV) delay adjustments. An AV interval is measured that corresponds to an interval between an atrial paced (Ap) event or an atrial sensed (As) event and a sensed ventricular (Vs) event. A candidate AV delay is set based on the AV interval and a bundle branch adjustment (BBA) value. A QRS characteristic of interest (COI) is measured while utilizing the candidate AV delay in connection with delivering a pacing therapy. The BBA value is adjusted and the candidate AV delay is reset based on the BBA value as adjusted. A collection of QRS COIs and corresponding candidate AV delays are obtained and one of the candidate AV delays is selected as a BBA AV delay. The pacing therapy is managed, based on the BBA AV delay.

Systems and methods for managing atrial-ventricular delay adjustments

Methods for implanting a pulse generator (PG) within a pectoral region of a chest of a patient and devices having the PG. The PG has a housing that includes a PG electrode. Methods also include implanting at least one lead having first and second electrode segments with the first electrode segment positioned along an anterior of the chest of the patient and the second electrode segment positioned along at least one of a posterior of the patient or a side of the patient. The first and second electrode segments are positioned subcutaneously at or below an apex of a heart of the patient, wherein the PG electrode and the first and second electrode segments are configured to provide electrical shocks for antiarrhythmic therapy.

Implantable medical systems and methods including pulse generators and leads

Methods, devices and program products are provided for determining an early battery depletion condition for a battery powered device. The method determines a charge consumption drawn externally from a battery cell by the device for a select period of time, obtains a measured cell voltage for the battery cell of the medical device, calculates a projected cell voltage based on the charge consumption and usage conditions, and declares an early depletion condition based on a relation between the measured and projected cell voltages.

Method and device for detecting early battery depletion condition

Methods and devices include making an incision at a single site of a patient. The single site located at an anterior of a chest or abdomen. The method also includes inserting a tunneling tool through the incision at the single site and preparing a first tunnel to a subcutaneous posterior location. A path of the first tunnel at least one of i) extends over a plurality of Intercostal gaps of the chest or ii) extends along and within one of the intercostal gaps. The method also includes positioning a first lead having an electrode within the first tunnel and preparing a second tunnel to a subcutaneous parasternal location along the chest. The method also includes positioning a second lead having an electrode within the second tunnel and positioning a pulse generator within a subcutaneous pocket and operatively coupling the first and second leads to the pulse generator.

Single-site implantation methods for medical devices having multiple leads

Methods for implanting a puke generator (PG) within a pectoral region of a chest of a patient and devices having the PG. The PG has a housing that includes a PG electrode. Methods also include implanting at least one lead having first and second electrode segments with the first electrode segment positioned along an anterior of the chest of the patient and the second electrode segment positioned along at least one of a posterior of the patient or a side of the patient. The first and second electrode segments are positioned subcutaneously at or below an apex of a heart of the patient, wherein the PG electrode and the first and second electrode segments are configured to provide electrical shocks for antiarrhythmic therapy.

A leadless implantable medical device (IMD) may include an electrode, a housing, and an energy transfer component. The housing retains a pulse generator configured to provide stimulation energy for delivery to a tissue of interest, a power supply, a memory storing programmable instructions, and a processor communicatively coupled to the memory. The processor is responsive to the programmable instructions to control operation of the leadless IMD. The electrode is securely affixed to the tissue of interest. The housing includes first and second body portions mated to one another at a detachable interface. The electrode is coupled to the second body portion. The energy transfer component is distributed between the first and second body portions and is configured to convey at least one of stimulation energy or sensed signals across the detachable interface when the first and second body portions are mated to one another.
