A method for performing bronchial denervation, the method comprising an electromyography system having a cryoablation device with at least two recording electrodes. The electromyography system being configured to calculate a difference between a first electromyogram signal received from the first recording electrode and a second electromyogram signal received from the second recording electrode to generate a recorded electromyogram and compare the recorded electromyogram to a reference electromyogram.

Apparatus and method for targeted bronchial denervation by cryo-ablation

An implantable cardiac defibrillator (ICD) system includes an ICD implanted subcutaneously in a patient, a defibrillation lead having a proximal portion coupled to the ICD and a distal portion having a defibrillation electrode configured to deliver a defibrillation or cardioversion shock to a heart of the patient, and a pacing lead that includes a distal portion having one or more electrodes and a proximal portion coupled to the ICD. The distal portion of the pacing lead is implanted at least partially along a posterior side of a sternum of the patient within the anterior mediastinum. The ICD is configured to provide pacing pulses to the heart of the patient via the pacing lead and provide defibrillation shocks to the patient via the defibrillation lead. As such, the implantable cardiac system provides pacing from the substernal space for an extravascular ICD system.

Implantable cardioverter-defibrillator (ICD) system including substernal pacing lead

Devices and implantation methods utilizing subcutaneous placement into a patient are disclosed for the insertion, advancement and positioning of a subcutaneous implantable medical device (SIMD) such as a medical electrical lead. The device for implanting the SIMD is configured having a pre-biased distal curve for creating a pathway to an implant location within a substernal space.

Systems and methods for implanting a medical electrical lead

A reservoir of a system for deploying an implantable lead to an extravascular location delivers a flow of fluid through a lumen of one or both of a tunneling tool and an introducer of the system. In some cases, the tunneling tool includes a pressure sensor assembly for monitoring a change in a pressure of the flow through the lumen thereof. Alternately, or in addition, a flow-controlled passageway, through which the flow of fluid from the reservoir is delivered to the lumen of the introducer, includes a compliant chamber to hold a reserve of the fluid. Fluid from the reserve may be drawn into the lumen of the introducer as the tunneling tool is withdrawn therefrom. Alternately, the introducer may include a chamber located between two seals, wherein fluid that fills the chamber is drawn distally into the lumen of the introducer, as the tunneling tool is withdrawn therefrom.

Systems and methods for deploying an implantable medical electrical lead

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.

Substernal leadless electrical stimulation system

Devices, systems, and methods for treating pulmonary conditions, such as COPD and asthma, by denervating bronchial tissue using cryoablation. In one embodiment, a device for bronchial denervation comprises: an elongate body having a distal portion and a proximal portion opposite the distal portion; a treatment element at the distal portion of the elongate body; and a first recording electrode located distal to the treatment element and a second recording electrode located proximal to the treatment element, the first and second recording electrodes being configured to record electromyograms. In one embodiment, the device includes a fluid delivery element that is within the treatment element and that has a plurality of orifices aligned with an equatorial portion of the treatment element.

Substernal implantable cardioveter-defibrillator (ICD) systems and methods for providing substernal electrical stimulation therapy to treat malignant tachyarrhythmia, e.g., ventricular tachycardia (VT) and ventricular fibrillation (VF) are described. In one example, an implantable cardioveter-defibrillator (ICD) system includes an ICD implanted in a patient and an implantable medical electrical lead. The lead includes an elongated lead body having a proximal end and a distal portion, a connector at the proximal end of the lead body configured to couple to the ICD, and one or more electrodes along the distal portion of the elongated lead body. The distal portion of the elongated lead body of the lead is implanted substantially within an anterior mediastinum of the patient and the ICD is configured to deliver electrical stimulation to a heart of the patient using the one or more electrodes.

Implantable cardioverter-defibrillator (ICD) system including substernal lead

Implantable cardiac pacing systems and methods for providing substernal pacing are described. In one example, a cardiac pacing system includes a pacemaker implanted in a patient and an implantable medical electrical lead. The implantable medical electrical lead includes an elongated lead body having a proximal end and a distal portion, a connector configured to couple to the pacemaker at the proximal end of the elongated lead body, and one or more electrodes along the distal portion of the elongated lead body, wherein the distal portion of the elongated lead body of the lead is implanted substantially within an anterior mediastinum of the patient and the pacemaker is configured to deliver pacing pulses to a heart of the patient.

Substernal electrical stimulation system

An implantable medical lead having an elongated lead body extending from a proximal end to a distal end, at least one conductor extending within the lead body from the proximal end to the distal end, and a fixation member having a proximal end and a distal end, the proximal end of the electrode configured to be electrically coupled to the distal end of the lead body. The fixation member includes a first delivery port and a second delivery port for releasing a therapeutic agent from the fixation member to tissue of a patient, wherein the first delivery port is positioned along the proximal end of the fixation member to deliver the therapeutic agent to endothelial cells along an endothelial layer of tissue, and the second delivery port is positioned along the distal end of the fixation member and spaced a distance from the first delivery port to deliver the therapeutic agent to myocardial tissue within a myocardial layer of the tissue, and wherein no delivery ports are positioned within the distance that the second delivery port is spaced from the first delivery port.

Helical fixation member assembly having bi-directional controlled drug release

An implantable medical device has a housing having a proximal end, a distal end and an outer sidewall extending from the proximal end to the distal end. A fixation sheath includes a housing sheath portion extending along the outer sidewall of the housing, and a fixation member portion extending from the housing sheath portion. The housing sheath portion is advanceable from a first position along the outer sidewall of the housing in which the fixation member portion is retracted toward the proximal end of the housing to a second position along the outer sidewall of the housing in which the fixation member portion is deployed to extend away from the housing distal end for anchoring the implantable medical device at an implant site.
