Abstract: An implant delivery system includes an implant, such as a wireless sensor, a first sheath, and a second sheath. The sheaths extend from a proximal end of the implant delivery system, and at least said first sheath extends to a distal end of said implant delivery system. The first sheath is positioned at least partially within said second sheath. The implant is connected to an exterior surface of the first sheath and positioned near an end of the second sheath. The first sheath and said second sheath are movable with respect to one another to deploy said implant to a desired location.

Abstract: Disclosed is a hemodynamic monitoring system, and method and associated harness device. The method and system are configured to allow a user that has received a permanent sensing implant within their vasculature to place a reader device in a hands free manner in communication with the implant through the chest of the user to measure at least one hemodynamic parameter such as pulmonary artery pressure. The reader device may be worn by the patient with a harness device to be configured to wirelessly communicate with said implant when the patient is in a specific patient state, such as resting, exercising, recovering, seated, or supine. The reader may be configured to take measurements from the implant when the patient is in the specific patient state, in order to acquire data from said implant related to said parameter and to upload said data to an external device.

Abstract: A wireless sensor reader is provided to interface with a wireless sensor. The wireless sensor reader transmits a narrowband, fixed frequency excitation pulse to cause the wireless sensor to generate a ring signal. The ring signal corresponds to the value of the physical parameter being sensed. The wireless sensor reader receives and amplifies the ring signal and sends the signal to a phase-locked loop. A voltage-controlled oscillator in the phase-locked loop locks onto the ring signal frequency and generates a count signal at a frequency related to the ring signal frequency. The voltage-controlled oscillator is placed into a hold mode where the control voltage is maintained constant to allow the count signal frequency to be determined. The low power, simple circuitry required to generate the excitation pulse allows the reader to be a small, battery operated unit. Alternative methods of frequency determination are also disclosed.
