Abstract
A system and method for quickly detaching an implant and for locating the detachment zone of a detachable implant. A sensor determines a sudden change in the local environment as the sensor passes from within a microcatheter to being exposed to the vasculature. The sensor may be a temperature sensor, ultrasonic sensor, pressure sensor or the like. If the detachable implant assembly uses a heater coil to detach the implant, the heater coil may be used as a sensor. Additionally, the implant itself may be used as a sensor if a change in electrical resistance is detectable as the implant exits the microcatheter and changes shape.
Claims11
A method for determining when an implant has advanced out of a microcatheter, the method comprising the steps of:
- advancing an implant through a lumen of a microcatheter;
- obtaining sensor data representative of an environment through which the implant is advancing;
- monitoring the sensor data to determine when the implant has advanced out of the microcatheter.
A method of deploying an implant from a pusher, the method comprising the steps of:
- advancing an implant through a lumen of a microcatheter;
- obtaining sensor data representative of an environment through which the implant is advancing;
- monitoring the sensor data to determine when the implant has advanced out of the microcatheter;
- and
- deploying the implant based on said monitoring.
