Device for preparing an implanted medical apparatus for extraction
View Patent ↗A device for preparing an elongated implanted medical apparatus, such as a cardiac lead, for extraction from the body of a patient. The device includes a first handle and a second handle. At least the first handle has a surface for receiving the implanted apparatus therealong. A wire member having a first end and a second end is positioned to span a distance between the surface of the first handle, and the second handle. The wire member first end is removably engaged with the first handle, and the wire member second end is removably engaged with the second handle. The wire member is sized and arranged to enable the wire member to be wound around a length of the implanted apparatus to facilitate extraction of the apparatus with a lead extraction device.
1. An assembly for removal of an implanted cardiac lead from a body passageway of a patient, comprising:
a cardiac lead disposed in a body passageway of a patient;
a first handle and a second handle, each of said handles comprising a handle body having a ledge surface engaged with a length of the cardiac lead therealong, each of said handle bodies having a channel extending inwardly from said ledge surface into an interior of said handle body, and having an aperture communicating with said channel, each handle further comprising a tab having a first end and a second end, said tab first end engaged with said handle body and said tab second end having a pin member engaged therewith, said pin member removably receivable in said channel via said aperture; and
a wire member having a first looped end and a second looped end, said wire member first looped end received in said channel of the first handle through an opening in said ledge surface, said wire member first looped end configured and arranged to be maintained in said channel when said pin member is received therein; and said wire member second looped end received in said channel of the second handle through an opening in the ledge surface, said wire member second looped end configured and arranged to be maintained in said channel when said pin member is received therein;
wherein said wire member is dimensioned to span a distance between said respective ledge surfaces; and
wherein said wire member is wrapped about the cardiac lead.
2. The assembly of claim 1 , wherein said cardiac lead has a free proximal end and a lumen extending therein, and further comprising a locking stylet receivable in said lumen, wherein said wire member is wrapped around said free proximal end of said cardiac lead while said locking stylet is received in said lumen.
3. The assembly of claim 1 , wherein said handles comprise a generally rigid composition, said tabs comprise a generally flexible composition, and said wire comprises an annealed metal alloy.
4. The assembly of claim 1 , further comprising an elongated tether member engaged with the wire member and capable of extending in a lateral direction therefrom.
5. The assembly of claim 1 , further comprising an extraction device configured such that a distal end of said extraction device is receivable over said cardiac lead.
