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: 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: 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.

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: 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: A system and devices 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. Catheter systems comprise distal end features adapted to cut and remove at least portions of an occlusion that generally correspond to dimensions of an inner lumen of a catheter.

Abstract: The present disclosure is directed, in one embodiment, to a wire centering sheath system in which wires outwardly extend from a sheath to brace against a vessel wall. The wire centering sheath system may be used to center endovascular devices.

Abstract: An endovascular device monitoring system is provided that determines, based on movement of the endovascular device past a selected reference location, at least one of a movement rate of a endovascular device and position of a distal end of a endovascular device in a body of a patient.

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.
