Abstract: A system for ablation and removal of occlusions from blood vessels is provided. Laser cutting systems and mechanical cutting systems are provided in catheter devices, the cutting systems operable to ablate, cut, dislodge, and otherwise remove occlusions within a blood vessel that may limit or prevent proper circulation. Pulsed aspiration systems are further provided, the pulsed aspiration systems operable to remove ablated, cut, or dislodged material without excessive or unnecessary removal of blood and fluid.

Abstract: Methods, devices and systems for separating an implanted object, such as a lead attached to a cardiac conduction device, from formed tissue within a blood vessel are provided. The methods, devices and systems for separating a lead from the tissue relate to dilating the tissue surrounding the lead from underneath the tissue and/or between the lead and the tissue.

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: A system and devices for ablation and removal of occlusions from blood vessels is provided. Laser culling systems and mechanical cutting systems are provided in catheter devices, the cutting systems operable to ablate, cut, dislodge, and otherwise remove occlusions within a blood vessel that may limit or prevent proper circulation. Catheter systems comprise distal end features adapted to cut and remove al least portions of an occlusion that generally correspond to dimensions of an inner lumen of a catheter.

Abstract: Lead tip removal is accomplished by first stabilizing an area around the lead tip attachment site in the heart wall. A balloon located at the tip of the lead when inflated expands substantially perpendicular to the lead, stabilizing the area around the lead tip. Upon further inflation, the balloon expands substantially parallel with the lead, causing the lead tip to pull away from the heart wall. In another embodiment, a sheath is inserted over the lead and advanced to the heart wall. A passive or active stabilization device is attached to the sheath tip to stabilize the area around the lead tip. In another embodiment, a balloon is located at the tip of the sheath that, when inflated, expands substantially perpendicular to the lead, stabilizing the area around the lead tip. The lead tip is removed with less force due to the stabilization provided to the lead tip area.

Abstract: This disclosure discusses various methods and devices for capturing plaque that is to be removed from a blood vessel after the plaque has been separated from the blood vessel or remaining plaque.

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.
