Abstract
An extractor for removing an implanted lead from a patient. The extractor includes a lumen dimensioned to receive the lead therein, a cutter at the distal portion for cutting tissue adjacent the lead, a distal clamping structure and a proximal clamping structure The proximal clamping structure and lead are relatively movable to extract the lead.
Claims13
An extractor for removing an implanted lead from a patient, the extractor comprising
- a lumen dimensioned to receive the lead therein;
- a cutter at a distal portion for cutting tissue adjacent the lead;
- a distal clamping structure spaced proximally of the cutter;
- and
- a proximal clamping structure spaced proximally of the distal clamping structure, the proximal clamping structure including a first plurality of radially spaced apart clamping members, the proximal clamping structure movable axially with respect to the distal clamping structure to extract the lead from the patient, wherein the distal clamping structure is substantially stationary and enables relative movement of the lead in response to proximal movement of the proximal clamping structure but prevents relative movement of the lead in a reverse direction, the distal clamping structure including a second plurality of radially spaced apart clamping members.

- a cutter at a distal portion for cutting tissue adjacent the lead;
- a distal clamping structure spaced proximally of the cutter;
- and
- a proximal clamping structure spaced proximally of the distal clamping structure, the proximal clamping structure including a first plurality of radially spaced apart clamping members, the proximal clamping structure movable axially with respect to the distal clamping structure to extract the lead from the patient;
- and
- an override mechanism to release the proximal and distal clamping structures to enable removal of the extractor from the lead.
An extractor for removing an implanted lead from a patient, the extractor having a proximal portion, a distal portion and a lumen to receive the lead therein, a cutter at the distal portion for cutting tissue adjacent the implanted lead, the extractor and lead incrementally relatively movable to swallow the lead as tissue is cut by the cutter adjacent the lead, the extractor including clamping structure having a distal position and a proximal position and movable in a proximal direction from the distal position to effect extraction of the lead, and further movable in a distal direction to return the clamping structure to the distal position, the clamping structure including a first plurality of clamping members, and an actuator operatively connected to the clamping structure to move the clamping structure between proximal and distal positions, and a second clamping structure having a second plurality of clamping members positioned distal of the first plurality of clamping members, the second plurality of clamping members preventing relative movement of the lead in one direction while enabling relative movement of the lead in the opposite direction.
