Abstract: Described here are devices and methods for performing atherectomies. Generally, the atherectomy devices may comprise a handle, a cutter assembly, and a catheter or catheter assembly therebetween. The cutter assembly may include a cutter housing and a cutter comprising a first cutting element and a second cutting element, each of which may be rotated relative to the atherectomy device to cut occlusive material.

Abstract: The invention encompasses devices and methods used to keep the objective lens of a viewing or illuminating device, specifically an endoscope, free from obstructive fluid and dirt; specifically a device having a hollow body designed to fit over an endoscope, a transparent lens cover film that is retained within the device and that is threaded in front of the objective lens of an endoscope, thereby maintaining a clear and unobstructed transparent window in front of the endoscope lens, and an endcap configured to engage opposing edges of the lens cover film in a sealing manner.

Abstract: Described here are devices and components for use in performing an atherectomy. Generally, the atherectomy devices may have a handle, a cutter assembly, and a catheter or catheter assembly therebetween. The cutter assembly may include a housing and a cutter comprising a proximal cutter and a distal cutter, each of which may be rotated relative to the atherectomy device to cut occlusive material.

Abstract: The devices and methods generally relate to treatment of occluded body lumens. In particular, the present devices and method relate to removal of the occluding material from the blood vessels as well as other body lumens.

Abstract: Devices, systems, and methods are employed to perform an atherectomy in an identified region to restore patency to arterial lesions. A bioactive material is introduced into the identified region before, after or during performing the atherectomy. The bioactive material can be introduced, e.g., on a balloon coated with the bioactive material, which is expanded in contact with the identified region to deliver the bioactive material. The bioactive material can be, e.g., at least one of a restenosis-inhibiting agent, a thrombus-inhibiting agent, and an anti-inflammatory agent.

Abstract: The devices and methods generally relate to treatment of occluded body lumens. In particular, the present devices and methods relate to removal of the occluding material from the blood vessels as well as other body lumens. In some variations, the methods comprise providing a vascular device comprising a catheter body, a cutter assembly, a drive mechanism, a torque shaft, and a deflecting mechanism. The methods may further comprise operating the drive mechanism to cut occlusive material, operating the deflecting mechanism to deflect the cutter assembly, and rotating the distal end of the catheter body to sweep the cutter assembly.
