    Abstract: The present disclosure relates to a system and method for coordinated laser delivery and imaging during an interventional procedure. A method may include activating an imaging source to provide a pulsed imaging signal and activating a laser source to provide a pulsed laser signal while the imaging source remains activated. The method may include coordinating the pulsed laser signal and the pulsed imaging signal to output each pulse of the pulsed laser signal and each pulse of the pulsed imaging signal in non-overlapping time windows. A system may include a controller in communication with the laser source and the imaging source for coordinating the output of the laser signal and the imaging signal.

    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: Catheter devices for ablation and removal of occlusions from blood vessels and methods of using the same are provided. Catheter devices are useful to ablate, cut, dislodge, and otherwise remove occlusions within a blood vessel that may limit or prevent proper circulation. Distal features of the catheter devices comprise arrangements of laser ablative or mechanical cutting features that generally provide enhanced surface areas and cutting functions. Spiral or helical arrangements are provided to aid in cutting operations.
