    Abstract: 一無線感測器之讀取器可供作為一無線感測器之介面。無線感測器之讀取器發射一窄頻帶，固定頻率之激發脈波，以致使無線感測器產生一振鈴信號。無線感測器之讀取器接收並放大該振鈴信號，並將信號送至一鎖相迴路。鎖相迴路中之一電壓控制振盪器鎖定於振鈴信號頻率上，並以與振鈴信號頻率相關之一頻率而產生一計數信號。電壓控制振盪器被置於一固持模態中，其中其控制電壓被維持常定以容許計數信號之頻率得以被判定。產生激發脈波的此低功率而簡單的電路可容許讀取器成為小型，以電池操作的裝置。其相關之頻率判定方法亦同時於此揭示。

    Abstract: Disclosed is a physiologic monitoring system comprising a central hub in communication with a management portal for communicating physiologic measurements taken from a plurality of peripheral devices on a patient. At least one non-invasive peripheral device may measure physiologic data from a patient and be in communication with said central hub. A system including an invasive peripheral device may be associated with said patient and be in communication with said central hub. The central hub may be scalable to collect and communicate measurements from the non-invasive peripheral device and the invasive peripheral device. The at least one non-invasive peripheral device may include a blood pressure cuff, an oxygen sensor, a weight scale, and an ECG monitor. The invasive peripheral device may include a wireless sensor reader that may be adapted to measure physiologic data from a sensor implant placed within the cardiovascular system of said patient.

    Abstract: Disclosed is a self-test device and method for assessing the functional performance of a reader device that is configured to interface with a wireless sensor. The self-test device may be configured to analyze the accuracy of a signal transmitted from the reader device or the accuracy of a signal received by the reader device. In one embodiment, the reader device may be configured to engage the self-test device to allow the reader to transmit a signal, such as a short pulse of energy or a short burst of radio frequency energy to cause the self-test device to output a resonant signal. The self-test device may receive the transmit signal from the reader and evaluate it against predetermined values. The evaluated signals may be used to assess the accuracy of the transmit signal of the reader device to identify potential calibration issues and initiate remedial action by an automated system or human intervention if needed. The self-test device may be built into a docking station where the reader is placed when not in use.

    Abstract: A method for monitoring a right atrial pressure (RAP) and a left atrial pressure (LAP) for diagnosis of a heart condition includes positioning a transseptal device with respect to a pulmonary artery to monitor at least one flow characteristic of blood through the pulmonary artery. The transseptal device is configured to generate one or more signals representative of the at least one flow characteristic. A right ventricular end diastolic pressure (RVEDP) and a left ventricular end diastolic pressure (LVEDP) are detected to facilitate monitoring the heart condition.

    Abstract: Disclosed is an implant and method of making an implant. The implant having a housing that defines a cavity. The housing includes a sensor comprising a base attached to a diaphragm wherein said base may be positioned within said cavity. The sensor may be a capacitive pressure sensor. The diaphragm may be connected to the housing to hermetically seal said housing. The sensor may include electrical contacts positioned on the diaphragm. The attachment between the base and the diaphragm may define a capacitive gap and at least one discontinuity configured to enhance at least one performance parameter of said implant.

    Abstract: Disclosed are a reader device, system, and method for communicating with a wireless sensor. The reader device may be configured to analyze the strength of a response signal transmitted from the wireless sensor in response to an excitation pulse generated by the reader device. In one embodiment, the reader device may be configured to engage be placed in a plurality of modes to allow the reader to transmit a signal, such as a short pulse of energy or a short burst of radio frequency energy to cause the wireless sensor to output a resonant signal. The reader device may receive the resonant signal from the wireless sensor and evaluate it against predetermined values. The evaluated signals may be used to assess the strength and the proximity of the reader device relative to the wireless sensor as it is implanted in a patient.
