    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: Methods and devices for separating an implanted object, such as a pacemaker lead, from tissue surrounding such object in a patient's vasculature system. Specifically, the tissue separating device includes a handle, an elongate sheath and a circular cutting blade that may extend from the distal end of the sheath upon actuating the handle. The circular cutting blade is configured to engage the tissue surrounding an implanted lead and cut such tissue in a coring fashion as the device translates along the length of the lead, thereby allowing the lead, as well as any tissue remaining attached to the lead, to enter the device's elongate shaft. The tissue separating device includes a cam mechanism at the distal portion of the sheath that allows the user of the device to more accurately control the extension and rotation of the cutting blade upon being actuated by the handle.

    Abstract: The present disclosure relates generally to the use of medical devices for the treatment of vascular conditions. In particular, the present disclosure provides devices and methods for using electrically-induced pressure waves to disrupt vascular blockages. The present disclosure not only provides devices and methods for using electrically-induced pressure waves to disrupt vascular blockages, but the present disclosure also provides devices and method for assisting the guidewire in penetrating an occlusion, devices and method for using a sealable valve in the tip of the balloon catheter to reduce the overall size and diameter of the balloon catheter, thereby allowing the balloon catheter to penetrate smaller size blood vessels and devices. Given the persistence of coronary artery disease (CAD) and peripheral artery disease (PAD), there remains a need for improved therapeutic methods designed not only to reduce vascular blockages in the short term, but also to prevent future complications such as restenosis.

    Abstract: Methods and devices for separating an implanted object, such as a pacemaker lead, from tissue surrounding such object in a patient's vasculature system. Specifically, the tissue separating device includes a handle, an elongate sheath and a circular cutting blade that may extend from the distal end of the sheath upon actuating the handle. The elongate sheath, particularly its distal end, includes a non-uniform wall thickness having one or more thicker portions in the outer sheath, particularly the outer cam member, and/or one or more thicker portions in an inner member disposed radially inward of the blade.

    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).

In particular, the present disclosure provides devices and methods for using laser-induced pressure waves to disrupt vascular blockages. The present disclosure not only provides devices and methods for using laser-induced pressure waves to disrupt vascular blockages, but the present disclosure also provides devices and method for assisting the guidewire in penetrating an occlusion, devices and method for using a sealable valve in the tip of the balloon catheter to reduce the overall size and diameter of the balloon catheter, thereby allowing the balloon catheter to penetrate smaller size blood vessels and devices and method that use stationary light absorbing material in lieu of and/or in combination of using liquid medium that flows into a balloon for a balloon catheter. Given the persistence of coronary artery disease (CAD) and peripheral artery disease (PAD), there remains a need for improved therapeutic methods designed not only to reduce vascular blockages in the short term, but also to prevent future complications such as restenosis.
