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.
Claims15
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 configured to engage the lead;
- and
- a proximal clamping structure spaced proximally of the distal clamping structure and configured to engage the lead, the proximal clamping structure including a first plurality of radially spaced apart clamping members, the proximal clamping structure relatively movable axially with respect to the distal clamping structure to extract the lead from the patient.
An extractor for removing an implanted lead from a patient, the extractor having a tubular portion defining a lumen to receive the lead therein, a proximal portion, a distal portion, a cutter at the distal portion for cutting tissue adjacent the implanted lead, and a carrier movable with respect to the tubular portion, 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 carried by the carrier, the 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 engageable with the lead, the clamping members extendable from the carrier and movable by the carrier upon movement of the carrier longitudinally with respect to the tubular potion, 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.
