    Abstract: A dilation balloon is wrapped in one or more patterns with a wire or braided material having diamond abrasive or other abrasive material bonded thereto. The wire or braided material is vibrated in one or more ways to enhance the cutting action of the wire abrasive. The wire abrasive may be vibrated using high, low, or even ultrasonic waves transmitted to the wire abrasive via local or remote methods. Alternatively, the dilation balloon may be dilated with a contrast media that exhibits a high absorption to laser light. The contrast material is lazed with a laser fiber or fibers inserted into the balloon interior, creating a substantial shockwave that vibrates the balloon and assists in the cracking or abrading of the surrounding plaque in contact with the dilation balloon. The cutting balloon may employ the abrasive coated wires described above or cutting blades.

    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 surgical device includes a handle, an elongate inner sheath and a circular cutting blade that extends 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 surgical 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 surgical device has a barrel cam cylinder in the handle assembly that imparts rotation of the blade and a separate cam mechanism in the tip of outer sheath assembly that imparts and controls the extension and retraction of the blade. The barrel cam cylinder and cam mechanism cooperate to cause the blade to rotate in a first direction and extend from and retract in the outer sheath due to a first actuation of the handle and to rotate in a second direction and extend and retract in the outer sheath due to a second actuation of the handle. The inner sheath and outer sheath are constructed of laser-cut hypotubes, thereby allowing the surgical device, particularly the sheath assembly, to have a smaller profile for navigating smaller sized vasculature.

    Abstract: A device for extending a lead according to some embodiments includes a body, a tubular member coupled to the body, the tubular member comprising an outer surface, wherein the outer surface is sized to insert into an inner lumen of a lead, the tubular member is movable between a first configuration in which the tubular member slides into the lead, and a second configuration in which at least a portion of the tubular member expands to engage an inner surface of the lead; and, an actuation mechanism operatively coupled to the tubular member, the actuation mechanism configured to move the tubular member between the first configuration and second configuration.

    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 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.
