METHOD AND APPARATUS FOR SENSING RESPIRATORY PRESSURE IN AN IMPLANTABLE STIMULATION SYSTEM
First Claim
Patent Images
1. A method of treating a respiratory dysfunction, the method comprising:
- positioning a sensor portion of a lead, via an intercostal access point, into an implanted location in which the sensor portion is coupled relative to respiratory pressures of a pleural space;
sensing, via the sensor portion at the implanted location, at least one of a temperature and the respiratory pressure; and
identifying a respiratory event based on a substantial change in the amplitude of at least one of the sensed temperature and the sensed respiratory pressure.

40. An implantable respiratory sensor system comprising:
-
a sensor lead including a lead body and a directional sensor portion, the directional sensor portion extending from the lead body and including a housing that contains at least; a pressure transducer located on a single side of the housing to define a directionality of the sensor portion; and a temperature transducer that is electrically independent of the pressure transducer; a first anchor located at a fixed position on the lead body that is spaced proximally from the sensor portion by a distance of about 3 to 9 centimeters, the first anchor configured with a pair of elements extending generally outward from opposite sides of the lead body to maintain the single side in an orientation facing toward the lungs; a second anchor located on the lead body proximal to the first anchor and being selectively movable along a length of the lead body. - View Dependent Claims (41, 42)
