    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: Catheters for ablation and removal of occlusions from blood vessels are 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. A helical or partially-helical inner surface structure is provided in the catheter, the structure operable to remove or translate dislodged material(s).

    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.

    Abstract: Embodiments include a catheter system comprising an elongated housing having a housing channel disposed between a first proximal end and a first distal end. The first distal end includes a ramp, having an inclining proximal section and an apex section, and a nose section. The catheter system further includes a rail wire channel in communication with the ramp but not the nose section and a laser delivery member being at least partially disposed within the housing channel and movable therein. In some embodiments, the catheter system includes a rail wire fixedly attached to and terminating at the first distal end of the elongated housing, wherein the rail wire extends through the rail wire channel, and wherein the laser delivery member is slidably coupled to the rail wire.
