Abstract: Methods and systems for separating an object, such as a lead, from formed tissue are provided. Specifically, a tissue slitting device is configured to engage patient formed tissue at a slitting engagement point. While the object is subjected to a first traction force, the tissue slitting device is caused to move further into the engaged tissue and slit the tissue past the point of engagement. The slitting device causes the tissue to separate along an axial direction of the length of the formed tissue and releases at least some of the force containing the object. The methods and systems are well suited for use in cardiac pacing or defibrillator lead explant procedures.

Abstract: Laser energy delivery devices and methods are provided. A laser energy delivery device may include a housing, and a coupling is carried by the housing and adapted to couple to a laser energy generator. A sheath is carried by the housing, and the sheath includes a distal end adapted to be disposed in the subject. A plurality of transport members are carried by the sheath, and the plurality of transport members are adapted to receive laser energy at the coupling, transmit laser energy through the sheath, and deliver laser energy to the subject. A fluid-driven motor is carried by the housing and adapted to be driven upon receiving a fluid from a fluid source. A drive wire is carried by the sheath and eccentrically coupled to the distal end of the sheath, and the drive wire is adapted to be rotatably driven by the fluid-driven motor and rotates to eccentrically rotate the distal end of the sheath.

Abstract: Devices, methods and systems for removing unwanted tissue from within a patient's vasculature system are provided. Specifically, a laser ablation catheter having a tip with an open, arched-shaped cross section is described. The cross section of the tip enhances the catheter's ability to ablate, separate, and/or dilate the various layers within a patient's vasculature, thereby facilitating the removal undesirable lesions and fibrous tissue within a patient's vasculature.
