摘要： An implantable medical device system and associated method monitor changes in transimpedance in a body tissue due to changes in cardiac pulsatility. A first dipole is used to deliver a non-stimulating electrical current. The first dipole includes a first electrode and a second electrode adapted to be deployed along a first body location. A second dipole is used to measure a voltage resulting from the non-stimulating electrical current being conducted through a portion of a patient's body. The second dipole includes a third electrode and a fourth electrode different than the first electrode and the second electrode and adapted to be deployed along a second body location spaced apart from the first body location.

摘要： A method and apparatus for positioning a lead within an anatomy is disclosed. The apparatus can be tracked relative to the anatomy to determine the position of selected portions of the anatomy. The positions of the portions of the anatomy can be used in determining an appropriate lead length to be positioned within the anatomy. Additionally, a determination of a lead length can be based upon statistical or acquired data of a selected population, according to an appropriate method.

摘要： A system and method for identifying the location of a medical device (42) within a patient's body may be used to localize the fossa ovalis for trans -septal procedures. The systems and methods measure light reflected by tissues encountered by an optical array. An optical array (44) detects characteristic wavelengths of tissues that are different distances from the optical array. The reflectance of different wavelengths of light at different distances from an optical array may be used to identify the types of tissue encountered, including oxygenated blood in the left atrium as detected from the right atrium through the fossa ovalis.

摘要： A delivery tool of a system for deploying medical diagnostics and/or therapy includes a deployment member and a sheath. An elastic cantilever element secured to a tubular sidewall of the deployment member, in proximity to a distal opening of a lumen formed by the sidewall, is spring biased to extend outward from the sidewall. When the cantilever element is received within the sheath, a sheath sidewall pushes the cantilever element inward, against the spring bias thereof, and a radius of curvature of the cantilever element approximately conforms to that of an outer surface of the deployment member sidewall. A helical track for receiving passage of a medical device helix fixation element therein may extend around a perimeter of the deployment member lumen, wherein a distal terminal end of the track is located in close proximity to the distal opening and generally opposite a free end of the cantilever element.

摘要： A medical device configured to convert an analog signal using an adaptable bit number. The medical device includes an analog-to-digital (A/D) converter for receiving an analog signal. The A/D converter has a full scale range and a total number of bits spanning the full scale range. The A/D converter converts the analog signal to a digital signal over conversion cycles using an adaptable bit number so that on at least a portion of the conversion cycles an adapted number of bits spanning a portion of the full scale range less than the total number of bits is used by the A/D converter to convert the analog signal.
