LEAD EXTRACTION METHODS AND APPARATUS

摘要

An apparatus configured to control a lead extraction tool for assisting in removal of an implanted lead. The apparatus comprises at least one valve configured to control fluid flow to the lead extraction tool. When the at least one valve is open, the at least one valve is configured to allow fluid stored in the apparatus to flow thereby applying, when the apparatus is fluidly coupled to the lead extraction tool, fluid pressure to at least one component of the lead extraction tool. The apparatus further comprises at least one controller configured to control opening and/or closing of the at least one valve.

1. A system for assisting in removing an implanted lead, the system comprising:
a device for separating tissue from the lead, the device comprising:
a body having a proximal portion and a distal portion, the body adapted to accommodate the lead;at least one expansion component capable of increasing a distance between the proximal portion and the distal portion at least in part by fluid pressure applied to the at least one expansion component;a separating component coupled to the at least one expansion component such that when fluid pressure is applied to the at least one expansion component, the separating component is forced in a forward direction along the lead to assist in separating tissue from the lead;at least one proximal anchoring component capable of providing pressure on the lead that resists movement of at least part of the proximal portion along the lead at least in part by fluid pressure applied to the at least one anchoring component to provide an anchor for the separating component to assist in separating tissue from the lead; andat least one distal anchoring component capable of providing pressure on the lead that resists movement of at least part of the distal portion along the lead at least in part by fluid pressure applied to the at least one distal anchoring component; and a control unit configured to operate the device, the control unit comprising at least one controller configured to cause fluid pressure to be applied to the at least one proximal anchoring component, the at least one expansion component, and the at least one distal anchoring component in a predetermined sequence.
