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.

Physiological monitoring system

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 base may define a capacitive gap and a vent wherein the electrodes may be positioned within said capacitive gap such that at least a portion of the electrical contacts extend through the vent. The implant may include a coil in electric communication with the sensor, said coil may be positioned within said housing. A printed circuit board having at least one component may be attached to the floating base.

Pressure sensing implant

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.

Wireless sensor reader assembly

A wireless circuit includes a housing, such as a hermetic housing, and at least one antenna coil wound about a coil axis within the housing. The coil axis may be substantially parallel to at least one wall of the housing, wherein the wall parallel to the coil axis is substantially thinner than other walls of the housing.

Implantable sensor enclosure with thin sidewalls

A wireless circuit includes a housing having at least one opening, and sensor connected to the housing at the opening. The sensor includes a first layer having a first dimension and a second layer having a second dimension shorter than the first dimension. The second layer may be positioned entirely within the housing and a surface of said first layer may be exposed to an exterior of the housing.

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.

Pressure sensor, anchor, delivery system and method

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.

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 reader uses an ambient reading or other information to select a subset of the possible ring signal frequencies, and tunes or adjusts its circuits and algorithms to focus on that subset.
