The electronics module comprises a housing and a processor disposed within the housing (101). An interface element (121, 123) interfaces with the sensing component so as to receive signals from the sensing component and provide the same to the processor. A sensor (105) is disposed within the housing (101). The sensor (105) monitors a property of the environment external the electronics module (100) through the housing (101). The housing (101) is constructed such that the sensor (105) has line of sight through the housing (101).

Disclosed are devices and methods for estimating blood pressure, which implement a pulse-transit-time-based blood pressure model that can be calibrated. Some implementations provide reliable and user friendly means for calibrating the blood pressure model using blood pressure perturbation methods and multiple sensors.

A method and system of universal, secure attachment with attachment detection mechanism, of a wearable sensor-unit to any article of clothing worn around the body in order to measure vital signals of a person, such as motion, movements and activity levels. The method and system permits: reliable attachment to any article of clothing; an attachment in any position to clothing or fabric worn by a person; and detection for the wearable sensor attachment to an article of clothing to minimize false alarms.

Embodiments relate to an insertion device that includes: a plunger coupled with a lock collar. The insertion device houses contents including: a striker including self-locking striker snap arm(s) where the striker is kept from firing by a striker spring captured between the plunger and the striker when the insertion device is in a cocked position; a sensor assembly; and a needle carrier that holds a piercing member, the needle carrier captured between the striker and a needle carrier spring where a self-releasing snap(s) keeps the needle carrier cocked, where the plunger prevents the self-releasing snap(s) from repositioning and releasing the needle carrier. The striker fires the needle carrier such that the self-locking striker snap arm(s) are positioned to allow the striker to snap down. The needle carrier is then retracted when the user releases the plunger and the piercing member is encapsulated within the insertion device.

An elongate medical device having an axis comprises an inner liner, a jacket radially outward of the liner, a braid comprising metal embedded in the jacket, a sensor, and at least one wire electrically connected to said sensor. The at least one wire is one of: embedded in the jacket and optionally disposed helically around the braid; extending longitudinally within a tube which extends generally parallel to the device axis and wherein the tube is embedded in the jacket; and disposed within a lumen, wherein the lumen extends longitudinally within the jacket.

An implantable medical device, battery and method include memory configured to store program instructions. At least one of circuitry or a processor are configured to execute the program instructions in connection with at least one of monitoring a biological signal or administering a therapy. The device includes a battery comprising a cell stack that includes an anode, a cathode, and one or more separator layers electrically insulating the anode from the cathode. The device includes a case having a feedthrough port and a feedthrough assembly disposed in the feedthrough port. The feedthrough assembly includes a ferrule having a lumen. An inner conductor is disposed within the lumen of the ferrule. The inner conductor is formed from a material having a first composition and a first coefficient of thermal expansion (CTE). An insulating core is disposed within the lumen of the ferrule and separates the inner conductor from the ferrule. The insulating core is formed from a material having a second composition and a second CTE. The first CTE of the inner conductor is equal to or greater than the second CTE of the insulating core and the first and second compositions are molecularly bonded with one another to form a hermetic seal between the inner conductor and the insulating core.
