Devices, systems, and methods for marking and/or reinforcing fenestrations in grafts are disclosed herein. In some embodiments, a radiopaque marker for a graft is provided. The marker can be secured to the graft in the area near a fenestration such that the marker is visible via radiographic imaging. The radiopaque marker can be in the form of a radiopaque thread, a radiopaque bead, a radiopaque additive, or a radiopaque adhesive. In some embodiments, the radiopaque marker is in the form of a circular disc shaped and sized to surround a fenestration, the circular disc being formed of a radiopaque material. The radiopaque marker can be configured to or can be attached to a reinforcement member configured to reinforce a fenestration such that one or more edges of the fenestration are protected and/or to aid in engagement with and sealing to a mating stent.

Technologies and implementations for a clip to connect coaxial cables onto a printed circuit board assembly (PCBA) are disclosed. The technologies and implementations facilitate improved signal integrity from the cable to various components of the PCBA. Additionally, the technologies and implementations help facilitate management of mechanical variations during connection of the coaxial cable.

In some embodiments, a wearable medical device system includes a processor configured to determine whether a patient requires electrical therapy to be provided via a plurality of therapy electrodes, the electrical therapy comprising discharging at least a portion of a stored electrical charge from an energy storage module, and if so, cause a fluid deploying mechanism to deploy a portion of the stored fluid to an interface between at least two therapy electrodes and the patient's skin prior to providing the electrical therapy, the deployed portion of fluid adapted to decrease the impedance measured by an impedance measurement circuit, and cause the fluid deploying mechanism to deploy an additional portion of fluid in response to the impedance measured by the impedance measurement circuit increasing above a threshold during the electrical therapy.

Patient electrodes, patient monitors, defibrillators, wearable defibrillators, software and methods may warn when an electrode stops being fully attached to the patient's skin. A patient electrode includes a pad for attaching to the skin of a patient, a lead coupled to the pad, and a contact detector that can change state, when the pad does not contact fully the skin of the patient. When the detector changes state, an output device may emit an alert, for notifying a rescuer or even the patient.

In embodiments, a wearable cardiac defibrillator system includes an energy storage module configured to store a charge. Two electrodes can be configured to be applied to respective locations of a patient. One or more reservoirs can store one or more conductive fluids. Respective fluid deploying mechanisms can be configured to cause the fluids to be released from one or more of the reservoirs, which decreases the impedance at the patient location, and decreases discomfort for the patient. In some embodiments an impedance is sensed between the two electrodes, and the stored charge is delivered when the sensed impedance meets a discharge condition. In some embodiments, different fluids are released for different patient treatments. In some embodiments, fluid release is controlled to be in at least two doses, with an intervening pause.

Detecting loss of full skin contact in patient electrodes

A wearable medical device includes a garment and a medical device. The medical device has a functionality that can transition between an operative state and an inoperative state. When the functionality is in the inoperative state, a protrusion extends so as to poke the patient, as an indication that steps need to be taken to make the device ready for use.

RFID-based sensors, RFID readers and software sense a changed condition. In one embodiment, an RFID-based sensor includes a base that may be placed at a location where a condition may change. The sensor includes an RFID tag that is coupled to the base. The sensor also includes a detector that can be electrically coupled to the RFID tag. If the condition changes, an electrical property of the detector also changes, impacting an operation of the RFID tag. The impacted operation can be detected by an RFID reader/interrogator so as to provide a notification. An advantage over the prior art is that the condition change can be sensed wirelessly over a domain that can be laborious or hazardous to access otherwise. Moreover, RFID based sensors can be made by modifying common RFID tags.
