An implantable vital sign sensor including a housing including a first portion, the first portion defining a first open end, a second open end opposite the first end, and a lumen there through, the first portion being sized to be implanted substantially entirely within the blood vessel wall of the patient. A sensor module configured to measure a blood vessel blood pressure waveform is included, the sensor module having a proximal portion and a distal portion, the distal portion being insertable within the lumen and the proximal portion extending outward from the first open end.

A biometric information presentation system that enables efficient training by obtaining biometric information without giving a subject a sense of discomfort. The biometric information presentation system uses a garment-type biometric information measuring apparatus including at least fabric having a 20% elongation stress of 20 N or less. A garment pressure of the garment-type biometric information measuring apparatus is 0.1 kPa or more and 1.5 kPa or less. A skin contact-type electrode is provided at a portion of the garment-type biometric information measuring apparatus at which a garment pressure is 0.3 kPa or more. The garment-type biometric information measuring apparatus is worn by the subject. From obtained electrocardiographic information is calculated an RRI, an indicator of parasympathetic activity and indicator of sympathetic activity. The biometric information presentation system presents this calculated result on a terminal device and presents an action based upon the result to achieve the efficient training.

A subcutaneously implantable device includes a housing including a receiving portion at a back end of the housing, a clip attached to the receiving portion, and an electrode. The clip is configured to move within the receiving portion between an open position and a closed position to increase or decrease an opening between the housing and the clip to anchor the device to a muscle, a bone, and/or a first tissue. The clip includes an anchoring portion that extends across a top of the housing, a mast portion within the receiving portion of the housing, and an anchoring structure extending from the anchoring portion. The anchoring structure is configured to attach to the muscle, the bone, and/or the first tissue. The electrode is configured to contact an organ, a nerve, the first tissue, and/or a second tissue. Circuitry in the housing is in electrical communication with the electrode and is configured to provide monitoring, therapeutic, and/or diagnostic capabilities with respect to the organ, the nerve, the first tissue, and/or the second tissue.

An implantable medical device, such as a sensor for monitoring a selected internally detectable physiological parameter of a patient, is attached to a fixation assembly that is deployable within the patient to position and orient the sensor to enable it to perform its function. The fixation assembly is formed having at least one flexible asymmetric connector where each fixation member includes a plurality of loops, wherein a first loop of the plurality of loops has a maximum pitch that is different from a maximum pitch of a second loop of the plurality of loops. The attachment of the housing and the fixation assembly includes providing a tubular member that is welded to the housing and crimped over a section of the fixation assembly.

Electrical sensing/stimulation apparatuses for positioning at least one electrode within body tissue are provided. An electrical sensing/stimulation apparatus may comprise an elongate lead body having at least one internal lumen, at least one sensing/stimulation electrode, a deployable/retractable displacement member that moves or biases at least one electrode towards a prescribed direction by the user, a tissue attachment mechanism for affixing the distal segment of the device to body tissue, and an atraumatic distal lead body termination. In a retracted configuration, the attachment mechanism is positioned substantially within the distal segment of the lead body, and in the deployed configuration, the attachment mechanism extends from the axis of the lead body to engage body tissue.

Provided is a sensor module, a method for manufacturing a sensor module, and a blood pressure measurement device that can improve the holding force onto a soft portion. A sensor module 63 of a blood pressure measurement device 1 includes: a sensor base 72; a pressure sensor portion 71 fixed to the sensor base 72; a sensor head cover 73 including, on an outer surface, an opening 73a in a region that comes into contact with a wrist 100 and an inner surface 73g formed with unevenness, the sensor head cover 73 being fixed to the sensor base 72 and forming a gap portion 79 that communicates with the opening 73a between the inner surface 73g, the sensor base 72, and the pressure sensor portion 71; and a soft portion 74 disposed in the gap portion 79 and, at least, filling up the opening 73a and covering the pressure sensor portion 71.

The digital connectivity of individual groups of networked mobile communication devices, electronic wearable, mobile and stationary gadgets with networked repositories-rendered functional and interactive touch-screens for rendering decades of early opportunities for, for preempting and treating and for concomitantly festering compliances for fostering said preemptions, treatments of atherosclerostic vascular diseases and metabolic syndrome.

An apparatus for estimating bio-information includes a sensor part configured to measure a pulse wave signal and a contact force of an object, while the object is in contact with the sensor part. The apparatus further includes a processor configured to extract a first feature from the measured pulse wave signal and the measured contact force, select one estimation model from a plurality of estimation models, based on a second feature of a user corresponding to the object, and estimate the bio-information, by inputting the extracted first features in the selected estimation model.

A grasping instrument for clamping tissue includes an outer tube, first and second jaw members supported by the outer tube, a carriage mounted within the outer tube and configured for longitudinal movement between an initial proximal position and an advanced distal position to cause corresponding movement of the first and second jaw members between an approximated condition and an open condition, a piston operatively coupled to the carriage, an inflatable membrane disposed within the piston and being selectively inflatable to a predefined internal pressure to cause corresponding distal longitudinal movement of the piston a predetermined distance and to cause proximal longitudinal movement of the carriage to apply a clamping force to the tissue disposed within the first and second jaw members and an indicator bar having visual indicators corresponding to various degrees of thickness of the tissue disposed within the first and second jaw members.
