    Abstract: Methods and devices for separating an implanted object, such as a pacemaker lead, from tissue surrounding such object in a patient's vasculature system. Specifically the tissue separating device includes a handle, an elongate sheath and a circular cutting blade that may extend from the distal end of the sheath upon actuating the handle. The circular cutting blade is configured to engage the tissue surrounding an implanted lead and cut such tissue in a coring fashion as the device translates along the length of the lead, thereby allowing the lead, as well as any tissue remaining attached to the lead, to enter the device's elongate shaft. The tissue separating device includes a cam mechanism at the distal portion of the sheath that allows the user of the device to more accurately control the extension and rotation of the cutting blade upon being actuated by the handle.

    Abstract: A dilation balloon is wrapped in one or more patterns with a wire or braided material having diamond abrasive or other abrasive material bonded thereto. The wire or braided material is vibrated in one or more ways to enhance the cutting action of the wire abrasive. The wire abrasive may be vibrated using high, low, or even ultrasonic waves transmitted to the wire abrasive via local or remote methods. Alternatively, the dilation balloon may be dilated with a contrast media that exhibits a high absorption to laser light. The contrast material is lased with a laser fiber or fibers inserted into the balloon interior, creating a substantial shockwave that vibrates the balloon and assists in the cracking or abrading of the surrounding plaque in contact with the dilation balloon. The cutting balloon may employ the abrasive coated wires described above or cutting blades.

    Abstract: A device for removing an implanted object from a body vessel includes an actuator having an elongated sheath extending therefrom, the elongated sheath including a proximal portion and a distal portion. A tubular outer member has a proximal end attached to the distal portion of the elongated sheath, with a ramped surface at a distal end of the tubular outer member which constricts a diameter of a bore formed in the tubular outer member. A tubular inner member is located within the tubular outer member, the tubular inner member including a proximal end operably connected to the actuator and a distal end opposite the proximal end, the distal end of the tubular inner member including a plurality of resiliently flexible blades positioned to interact with the ramped surface of the tubular outer member such that the ramped surface is operable to deflect the resiliently flexible blades radially inwardly as the tubular inner member is advanced distally within the tubular outer member.
