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. A method for preparing an elongated implanted medical apparatus for extraction from the body of a patient, comprising:
positioning a device for engagement with a free end of the elongated implanted medical apparatus, the device comprising a first handle, a second handle, and a wire member spanning a distance between the handles, the wire member having a first end removably engaged with the first handle and a second end removably engaged with the second handle;
aligning the elongated implanted apparatus along a surface of the first handle;
winding the second handle around a length of the elongated implanted apparatus in a proximal direction from the first handle such that the wire is wrapped around said length; and
removing said first and second handles from said wire wrapped around said length of the elongated implanted apparatus.
2. The method of claim 1 , wherein the surface of the first handle comprises a ledge, and the implanted apparatus is aligned along said ledge of the first handle.
3. The method of claim 1 , wherein the elongated implanted apparatus comprises a cardiac lead having one or more cables extending therein, at least one of said cables extending laterally through an outer surface of said cardiac lead, and wherein said winding step comprises wrapping the wire around said cardiac lead and said laterally extending cable.
4. The method of claim 3 , wherein said cardiac lead includes a lumen extending therein, further comprising a step of introducing a first end of a locking stylet into said lumen, and wherein said winding step comprises wrapping the wire around the cardiac lead, the laterally extending cable, and a second end of the locking stylet.
5. The method of claim 4 , further comprising a step of advancing a lead extraction device over the cardiac lead, laterally extending cable, and second end of the locking stylet having said wire wrapped therearound.
