Abstract: An embolic implantation system configured to deliver an embolic implant intravascularly to a treatment site includes an elongated delivery tube to which the embolic implant is detachably attached by a flexible loop extending through a retaining ring or opening on the embolic implant and an elongated detachment member or pull wire extending through the delivery tube and flexible loop. The pull wire has a bump near its distal end that inhibits the pull wire from moving further distally when the bump presses distally against the flexible loop and/or retaining ring. The flexible loop and retaining ring thereby serve as a distal obstruction obstructing distal movement of the bump and thereby distal movement of the pull wire into the implant.

Abstract: A battery-powered tracking component may be attached to a sterilization case. The tracking component may collect, store and transmit usage information associated with the sterilization case. The supplying of power to the tracking component may be temporarily stopped during autoclave processes. As the high temperatures and pressurized steam of autoclave processes may drain an active battery, the lifespan of the battery may be elongated by deactivating the battery during the autoclave processes. A temperature sensor may detect when the temperature of the sterilization case rises above a threshold indicating a start of the autoclave process, and when the temperature of the sterilization case falls below a threshold indicating an end of the autoclave process. The usage information may include a count of autoclave processes and durations of time periods between autoclave processes. The usage information may be used to determine times at which autoclave processes are performed.
