A method and apparatus are disclosed for using photoplethysmography to obtain physiological parameter information related to respiration rate, heart rate, heart rate variability, blood volume variability and/or the autonomic nervous system. In one implementation, the process involves obtaining (2502) a pleth, filtering (2504) the pleth to remove unwanted components, identifying (2506) a signal component of interest, monitoring (2508) blood pressure changes, monitoring (2510) heart rate, and performing (2512) an analysis of the blood pressure signal to the heart rate signal to identify a relationship associated with the component of interest. Based on this relationship, the component of interest may be identified (2514) as relating to the respiration or Mayer Wave. If it is related to the respiration wave (2516), a respiratory parameter such as breathing rate may be determined (2520). Otherwise, a Mayer Wave analysis (2518) may be performed to obtain parameter information related to the autonomic nervous system.

An anchor and procedure for placing a medical implant, such as for monitoring physiological parameters. The anchor includes a central body in which a medical implant can be received. arms and members extend radially from first and second ends, respectively, of the central body. Each member defines a leg extending toward distal portions of the arms to provide a clamping action. The anchor and its implant are placed by coupling first and second guidewires to first and second portions of the anchor, placing an end of a delivery catheter in a wall where implantation is desired, inserting the anchor in the catheter with the guidewires to locate the anchor within the wall, deploying the arms of the anchor at one side of the wall followed by deployment of the members at the opposite side of the wall, and thereafter decoupling the guidewires from the anchor.

A cardiac care product, based on the distributed sensor based mobile/remote monitoring system, is also disclosed. The product comprises a distributed sensor system including at least one patch for wirelessly monitoring a physiological parameter; and a biostrip for providing analysis of the blood of a person. The product further includes a mobile device for receiving signals from the distributed sensor system. The mobile device has one mechanism that includes a real-time wireless monitoring of the physiological parameter and a second mechanism that monitors the analysis of the blood.

The present invention monitors and interprets physiological signals and spontaneous breathing events to detect the onset of arousal. Once the onset of arousal is determined, the present invention determines adjustments that are needed in the operation of a therapeutic device to avoid or minimize arousals. In one embodiment, the present invention includes one or more sensors which detect a patient's physiological parameters, a controller which monitors and determines the onset of arousal based on the physiological variables received from the sensor, and a therapeutic treatment device which is controlled by the controller. The sensor can be a combination of one or more devices which are able to monitor a physiological parameter that is used by the present invention to determine the onset of arousal or the onset of a sleep disorder. The sensors can be integrated into one unit or may operate independent of the others.

The RFID apparatus is arranged to be in electrical communication with at least the pair of drive electrodes or the pair of detection electrodes. Methods of using the device are also provided.

Described herein are apparatuses (e.g., garments, including but not limited to shirts, pants, and the like) for detecting and monitoring physiological parameters, such as respiration, cardiac parameters, and the like.

A system for monitoring blood pressure and other physiologic parameters is provided. The system is designed such that it can be delivered to the patient with ease and minimal invasion. The system contains at least one self contained implantable sensing device consisting of a sensor, an electrical circuit for signal conditioning and magnetic telemetry, a biocompatible outer surface and seal, an anchoring method, and an external readout device. The implant is small in size so that it may be delivered to the desired location and implanted using a catheter, although direct surgical implantation is also possible. The circuit, sensor, and antenna for telemetry are packaged together and sealed hermetically to the biologic environment. The larger readout unit remains outside the body but proximal to the implant for minimizing communication distance.

An anchor for a medical implant, a method of manufacturing an anchor, and a delivery system and method for delivering a medical implant, such as for monitoring physiological parameters, for example, for diagnosing and/or monitoring and/or treating cardiovascular diseases, such as CHF and CHD. The anchor includes a base member, arms, legs, features for securing the medical implant to the base member, and features for connecting the anchor to a connector. The anchor has a deployed configuration in which the arms radially project from a first end of the base member and the legs radially project from an opposite end of the base member. When deployed, the arms and legs terminate at extremities that are opposing but not aligned with each other.

A physiological monitoring system for noninvasively monitoring physiological parameters of a subject, comprising a fitness monitoring system for monitoring physiological parameters of a subject engaged in a physical activity, in accordance with one embodiment of the invention, includes (i) a monitoring garment adapted to cover at least a portion of a subject's torso, (ii) a magnetometer subsystem including a first magnetometer and a second magnetometer, wherein the first and second magnetometers are responsive to changes in distance therebetween, wherein the magnetometer subsystem is configured to generate and transmit a signal representative of a change in the distance between the first and second magnetometers, wherein the first and second magnetometers are incorporated into the monitoring garment, and wherein the first and second magnetometers are proximate to the subject's chest region when the monitoring garment is worn by the subject.

The stretchable conductive ink patterns may be stretched more than twice their length without breaking or rupturing.

A method for providing and adjusting cerebral cooling in response to changes in a physiological parameter. A spray having a boiling point between 38-300° C. is delivered to the surface of a patient's nasal cavities. The spray causes cooling by direct heat transfer through the nasopharynx and hematogenous cooling through the carotids and the Circle of Willis. A physiological parameter, such as cerebral temperature, changes in cerebral blood flow or brain oxygenation is monitored. The delivery rate of the spray is adjusted in response to the physiological parameter.
