A lead locking device has a lead insertion member having a proximal end and a distal end and has a lead engaging assembly. The lead insertion member defines a lumen extending along a longitudinal axis between the distal end and the proximal end of the lead engaging assembly. A mandrel disposed in the lumen of the lead engaging assembly extends along substantially the entire length of the lumen and protrudes beyond the most proximal end of the lead insertion member. The mandrel includes a distal portion in slidable contact with at least a portion of the lead engaging assembly. The lead engaging assembly has a first configuration while being inserted into a lumen of a lead and a second configuration while engaging the lead from within the lumen of the lead. The lead engaging member has at least two expansion jaws that, in the first configuration, define a substantially cylindrical body. The expansion jaws translate radially outwardly from the longitudinal axis to engage the lumen of the lead when in the second configuration.

Lead locking device and method

The invention provides an apparatus for cutting an endocardial lead within a patient. The apparatus includes a tubular member and a tension member disposed therein. The tension member includes a distal end and a proximal end. A blade is affixed to the distal end of the tension member and an adjustment mechanism is adapted to adjust the tension member and blade between an extended position and a retracted position. The adjustment mechanism includes a female member, a male member and an anchor. The anchor is affixed to the proximal end of the tension member and the male member. Insertion and withdrawal of the male member within the female member moves the tension member and the blade between the extended position and the retracted position. An alternate embodiment includes a capture mechanism or guide wire for drawing the apparatus and lead closer together before extending the blade and cutting the lead.

Endocardial lead cutting apparatus

A lead locking device has a lead engaging member with a mandrel extending along a lumen and attached to the distal end of the lead engaging member such that it extends beyond the proximal end of the lead engaging member. The lead locking device also has a loop handle attached to the proximal end of the mandrel. The lead engaging member has a first configuration which is narrower than a second configuration and is sufficiently long to extend along substantially the entire length of a lead to be removed from a patient's body. At the distal end, a spring coil is disposed around a tapered section of the mandrel to improve tracking of the lead locking device through the inner lumen of a pacing or defibrillator lead.

A coupler for interfacing a light source, such as a laser, and a fiber optic cable is disclosed. The coupler includes a slide mount having a channel that is adapted to receive optical fibers. The channel extends from a proximal end of the slide mount to a distal end of the slide mount. The proximal end of the slide mount is adapted to fit into an aperture of the light source and the distal end of the slide mount is adapted to transmit light to the fiber optic cable. The coupler also includes a clamp that is mounted on the slide mount adjacent to its proximal end. The clamp covers at least a portion of the channel, thereby securing the optical fibers within the channel without the use of an adhesive.

Proximal coupler for optical fibers

A lead locking device has a lead engaging member with a mandrel extending along a lumen and attached to the distal end of the lead engaging member such that it extends beyond the proximal end of the lead engaging member. The lead locking device also has a loop handle attached to the proximal end of the mandrel. The lead engaging member has a first configuration which is narrower than a second configuration and is sufficiently long to extend along substantially the entire length of a lead to be removed from a patient's body. Methods of removing a lead from a patient's body include attaching a lead locking device along substantially the entire length of the lead and applying traction to the proximal end of the lead locking device.
