The function of a strain relief loop of an implantable medical lead is preserved by inhibiting restriction of the strain relief loop from tissue growth onto the strain relief loop. The restriction may be inhibited by either obstructing tissue growth and/or by utilizing a mechanical advantage to overcome the restriction. The tissue growth may be obstructed be isolating the interior of the strain relief loop such as by enclosing the strain relief loop or including an object within the loop. The mechanical advantage to overcome restriction from tissue growth may be provided in various ways such as utilizing a spring loaded mechanism or a structure such as an elastic mesh, tube, or mold having an inherent bias toward a steady state position.

Disclosed is an ultrasonic probe in which a supporting member is provided with a buffer unit to mitigate an outside impact. The ultrasonic probe includes a transducer rotatably provided, a shaft having the transducer mounted thereto, and a supporting member rotatably supporting the shaft, wherein the supporting member is provided with a buffer unit to mitigate an outside impact.

The invention describes an implantable pressure sensor having a housing, wherein the housing has walls and two or more pressure transfer membranes bounding an internal volume, wherein the pressure transfer membranes are not coplanar.

Embodiments of a wearable device are provided. The wearable device comprises a reusable component and a disposable component. The disposable component comprises a patient engagement substrate comprising adhesive on a bottom side, an electrode on the bottom side, a disposable component electrical connector, and a disposable component mechanical connector. The reusable component comprises a plurality of sealed housings mechanically coupled to each other and movable with respect to each other, each of the plurality of housings containing one or more of a capacitor and a controller, a reusable component mechanical connector adapted to removably connect to the disposable component mechanical connector, and a reusable component electrical connector adapted to removably connect to the disposable component electrical connector. The device can comprise a cardiopulmonary physiologic monitor or an automatic external defibrillator, among other types of devices.

The distal end of the catheter can be constructed to include one or more features to provide strain relief to wiring of multiple single axis sensors. In some examples, the multiple single axis sensors and associated wiring can be manufactured over a flexible tube that can be placed over a movable support member. In some examples, wiring can be wound an increased number of consecutive traverse turns on a distal and/or proximal side of a single axis sensor, and a shrink sleeve may be positioned over the traverse turns. In some examples a wire shield transition point can be positioned on a straight portion in a proximal direction to the distal portion of the catheter.

An exemplary system and method are disclosed for a wearable soft bioelectronic system configured with strain isolators that can isolate its sensor electrode or other sensors in proximity or in contact with the skin from temporary stretching and relative motion of the skin due to gross body movements, e.g., walking. The exemplary system employs hard-soft materials and an isolation structure that facilitates the use of a wearable sensor that can be placed on the surface of the skin and minimize motion artifacts in the acquired signals during physical motion by the wearer. The exemplary system can employ stretchable sensors in combination with the strain isolators.

An oximeter probe includes sensor head with a probe face having one or more sensor structures to make measurements, a handle, and an elastic member connected between the handle and the base. A user can hold the handle while measurements are made and the elastic member permits the handle to flex relative to the sensor head with one or more sensor structures.

A pressure resistant medical cable enclosure is provided, including a clamshell, a printed circuit board, and at least one overmold, wherein the clamshell is configured for assembly over the printed circuit board for a medical cable, one overmold provided at least partially around the clamshell layer with minimal overlap between the overmold and the printed circuit board in the vertical direction.
