摘要： An apparatus for evaluating a degree of recovery of a living subject from a surgical operation which the subject has undergone, the apparatus including a circulatory-organ-relating-information obtaining device for iteratively obtaining, after the operation, a piece of circulatory-organ-relating information relating to a circulatory organ of the subject, and a recovery-degree evaluating device for evaluating the degree of recovery of the subject, based on at least one piece of circulatory-organ-relating information obtained by the circulatory-organ-relating-information obtaining device.

摘要： An apparatus for monitoring fluid pressure includes a reusable base section, and a disposable dome section detachably connected to the base section. The disposable dome section defines a fluid pathway and includes a dome viewing segment in fluid communication with a flush segment and a stopcock segment. A pressure transducer sensor is disposed in the reusable base section and is adapted to produce electrical signals proportional to fluid pressures sensed in the fluid pathway. A usage indicator can be disposed in the base section to provide a visual indication of usage of the apparatus within a predetermined number of uses. A calibration port can be provided in the base section to allow for simple calibration by the user without violating the sterility of the apparatus. The ability to reuse the base section with the sensor component reduces the cost of the apparatus, while the disposability of the dome section with the fluid pathway ensures sterility for each use.

摘要： An implant device is provided which is responsive to an external interrogation circuit. The implant device includes a structure implantable within a living animal and operatively configured to carry out or assist in carrying out a function within the living animal. The device further includes an electrically passive sensing circuit integral with the structure for sensing a parameter associated with the function. In particular, the sensing circuit includes an inductive element wherein the sensing circuit has a frequency dependent variable impedance loading effect on the interrogation circuit in response to an interrogation signal provided by the exciter/interrogator element, the impedance loading effect varying in relation to the sensed parameter.

摘要： A method and apparatus for determining whether a patient with congestive heart failure (CHF) will benefit from pacing therapy through the use of an implantable cardiac rhythm management device. A patient's right ventricular and left ventricular pressures are measured, and the patient's PP_Area is calculated for each normal heartbeat that occurs during the testing period. Depending upon the value of the patient's mean PP_Area, it can be determined whether the patient will or will not respond well acutely to pacing therapy. A mean PP_Area value of greater than or equal to a predetermined threshold, which is about 0.3, indicates that the patient is a responder to pacing therapy, while a value of less than the predetermined threshold of about 0.3 indicates that the patient is a non-responder.
