Abstract
A medical device system and method are disclosed for treating obstructive sleep apnea. The system includes a pulse generator and a medical electrical lead including multiple electrodes carried by a distal portion of an elongated lead body. The method includes advancing the distal portion within protrusor muscle tissue below the oral cavity and delivering electrical stimulation pulses via the electrodes to sustain a protruded state throughout a delivery time period to sustain a protruded state of a patient's tongue throughout the therapy delivery time period. The therapy delivery time period may span multiple respiration cycles.
Claims18
A medical device system, comprising:
- a first medical electrical lead comprising:
- a first elongated lead body extending from a first proximal end to a first distal end with a first distal portion proximate the first distal end, the first distal portion configured for percutaneous implantation;
- and
- a first plurality of electrodes spaced apart along the first distal portion for implantation within a first portion of a protrusor muscle tissue, wherein the first plurality of electrodes are configured to be implanted proximate, and without attaching, to a first nerve of the first portion of the protrusor muscle tissue and proximate to a first motor point of the first portion of the protrusor muscle tissue;
- a second medical electrical lead comprising:
- a second elongated lead body extending from a second proximal end to a second distal end with a second distal portion proximate the second distal end, the second distal portion configured for percutaneous implantation;
- and
- a second plurality of electrodes spaced apart along the second distal portion for implantation within a second portion of the protrusor muscle tissue, wherein the second plurality of electrodes are configured to be implanted proximate, and without attaching, to a second nerve of the second portion of the protrusor muscle tissue and proximate to a second motor point of the second portion of the protrusor muscle tissue;
- and
- a pulse generator configured to:
- receive the first proximal end and the second proximal end;
- and
- deliver electrical stimulation pulses to activate the first portion of the protrusor muscle tissue via the first plurality of electrodes and to activate the second portion of the protrusor muscle tissue via the second plurality of electrodes to cause a tongue of a patient to advance, wherein to deliver electrical stimulation pulses, the pulse generator is configured to deliver the electrical stimulation pulses to the first motor point of the first portion of the protrusor muscle tissue and deliver the electrical stimulation pulses to the second motor point of the second portion of the protrusor muscle tissue.
A method comprising:
- advancing a hollow delivery tool percutaneously into protrusor muscle tissue of a patient;
- advancing a first distal portion of a first elongated lead body of a first medical electrical lead percutaneously into the protrusor muscle tissue to position a first plurality of electrodes carried by the first distal portion within the protrusor muscle tissue, wherein the first plurality of electrodes are configured to be implanted proximate, and without attaching, to a nerve of the protrusor muscle tissue and proximate to a motor point of at least one protrusor muscle of the protrusor muscle tissue;
- advancing the first distal portion into the protrusor muscle tissue laterally adjacent to a medial plane of the protrusor muscle tissue to position the first plurality of electrodes along a first side of the protrusor muscle tissue;
- and
- advancing a second distal portion of a second medical electrical lead percutaneously into the protrusor muscle tissue laterally adjacent to the medial plane of the protrusor muscle tissue on a second side opposite the first side of the protrusor muscle tissue to position a second plurality of electrodes carried by the second distal portion along the second side of the protrusor muscle tissue.
