摘要:
Aspects include methods and apparatuses for determining change over time in one or more measured regions of a body using a plurality of data sets obtained by analysis of applied signals to said region. The method may include transmitting and receiving one or more of electromagnetic wave signals, applied acoustic wave signals and electrical signals transmitted through or reflected off of a portion of the measured body region.

The invention relates to methods and devices for remote or distributed continuous monitoring of physiologically relevant states. The invention provides for methods to automatically detect deviations or other states in physiological parameters and automatically alert a measured subject, user or other authorized party. The device provides for a universal platform for sensors, and further provides for the automatic compensation or distribution of devices or bioactive agents at appropriate levels and/or intervals in response to deviations or other states sensed in various physiological parameters.

Systems and techniques for monitoring hydration. In one implementation, a method includes measuring an electrical impedance of a region of a subject to generate an impedance measurement result, and wirelessly transmitting the data to a remote apparatus. The probe with which impedance is measured may in the form of a patch adhesively secured to the subject.

Systems and techniques are provided for monitoring hydration. In one implementation, a method includes measuring an electrical impedance of a region of a subject to generate an impedance measurement result. The result may be correlated with a blood loss condition.
摘要:
A structure for and method of manufacture of structures for implantation within the tissue of a mammalian subject are disclosed. These structures can be utilized in applications such as the delivery of therapeutic drugs to the tissue of the subject or the sampling of biofluids for the purposes of diagnosis. In one embodiment of the invention, a rigid structure has defined ingrowth features on a surface intended to contact tissue of the subject and defined passage features which provide a fluid path from the surface intended to contact tissue to another surface. The dimensions of these defined features vary based on the particular application, as the ingrowth features are of a dimension and spacing to promote ingrowth of the surrounding tissue, and the passage features are of a dimension to inhibit the passage through the structure of cells from the surrounding tissue.

The invention relates to a parenteral therapeutic agent delivery device. The therapeutic agent delivery device has a disposable section and an implant section suitable for long term implantation within the tissue of a subject. When necessary, the disposable section can be detached from the implant section, and a new disposable section can be attached. The disposable section may contain a reservoir containing the therapeutic agent, a pump for dispensing the therapeutic agent, controlling circuitry for regulating the dispensing of the therapeutic agent, and transceiver circuitry and an antenna for wireless communication with external devices.
摘要:
A medical device with an implantable portion comprises, in part, an encapsulation sensor. In preferred embodiments, the encapsulation sensor comprises at least two electrodes and a circuit configured to sense impedance between the electrodes. Cell accumulation and fibrous capsule growth causes an increase in impedance. Functionality of the sensor can be evaluated based at least in part on the sensed impedance.
