Embodiments described herein relate to apparatus and techniques for aligning and coupling a sensor device to a wearable patch. A shoe apparatus is coupled to the wearable patch. The sensor device is coupled to the shoe apparatus via one or more connectors of the shoe apparatus. As the sensor device is inserted into the shoe apparatus, features of the shoe apparatus enable alignment of the sensor device with the shoe apparatus and the one or more connectors.

Self-aligning device to patch interface

Embodiments of the present disclosure generally relate wearable patches having rigid inserts. The rigid insert is positioned adjacent to one or more connectors, such as studs for receiving sockets to distribute the force transferred to a patient when reconnecting a socket to the stud. The rigid insert may be sized to maintain flexibility in areas of the wearable patch. An optional adhesive layer may be applied to the wearable patch adjacent the rigid insert to reduce the likelihood of delamination of the wearable patch.

Bridge connectors employing flexible planar bodies having signal pathways coupling control devices with biometric sensors are disclosed. Sensors are placed in contact with a patient to detect a health condition and generate an output signal based on the health condition. A control device is linked to the sensors to receive the output signal for collection, analysis, storage, display, and/or subsequent transfer. A bridge connector includes a planar body with predetermined flexibility and signal pathways extending between data ports. By removably coupling the bridge connector to the control device and the sensors secured to the patient, the control device may be physically supported by the patient with minimal discomfort and low-cost biometric sensors may be used. In this manner, sensor replacement costs are reduced and the useful lives of the sensors can be maximized as the designed flexibility of the bridge connector facilitates removable coupling with the biometric sensors.

Deflectable catheter systems, apparatuses and methods utilizing thermal expansion to influence catheter deflection. A representative embodiment includes a catheter having one or more pull wires or other tensioning elements. One end of the tensioning element(s) is connected at a distal portion of the catheter to facilitate shaft deflection upon pulling the tensioning element(s). A heat-sensitive control member(s) is coupled to a proximal portion of the tensioning element(s). The elongate tensioning element(s) is pulled in a proximal direction to deflect the distal portion of the catheter in response to a temperature change applied to the heat-sensitive control member.

Catheter having proximal heat sensitive deflection mechanism and related methods of use and manufacture

Disclosed herein are various deflectable catheter systems that utilize materials having negative coefficients of thermal expansion to cause the catheter to deflect. A representative embodiment of the present invention includes a catheter having a heat-sensitive control member located outside the distal end of the catheter, but which is in mechanical communication with the distal end of the catheter such that heat may be applied to the control member to cause the distal portion to deflect. The applied heat, however, does not introduce any significant heat into the distal end of the catheter. The system may also include a processor to estimate an amount by which the catheter has been deflected based in part on temperature information of the control member, or even resistance measurements for the control member. The system may also include calibration systems and methods. Also disclosed herein are methods of use and methods of manufacturing system that utilize materials having negative coefficients of thermal expansion as control members.
