摘要:
A snare for deployment or retrieval of an implantable medical apparatus. The snare includes a shaft, and a tip distal of the shaft. The tip includes an extendable member capable of self-centering the implantable apparatus during a deployment or retrieval. The extendable member is selectively receivable in the tip, distally extendable from the tip, and rotatable relative to the tip. An activatable handle is engaged with the shaft. A wire has an end engaged with the handle and an end engaged with the tip. Upon activation, the wire is urged in a proximal direction, resulting in a flexure of the tip. An elongated mechanism has a proximal portion engaged with the handle, and a distal portion engaged with the tip extendable member. The elongated mechanism is configured for selectively controlling the receiving, deploying, and rotating of the extendable member.
