Telescoping, self-driving, and laterally-pushing atherectomy devices are provided, each having a flexible sheath, a cutter with helical flutes, and a drive assembly. The drive assembly can have a flexible driveshaft rotatably translational with the lumen of the flexible sheath, a positive displacement pump to transport cut tissue, and a flexible drive shaft that can be longer than the flexible sheath for a reversible telescoping of the drive assembly from the lumen of the flexible sheath. The positive displacement pump can be a screw pump having a drive screw portion exposed for contact with a vascular lumen for a self-driving of the device through the vascular lumen. A reversibly-expandable, lateral pushing member can be included at the distal end of the flexible sheath for a lateral pushing of the cutter. Improved cutting heads, and methods of making them, are provided for cutting a combination of soft and hard plaque.

Hybrid atherectomy devices

Telescoping, self-driving, and laterally-pushing atherectomy devices are provided, each having a flexible sheath, a cutter with helical flutes, and a drive assembly. The drive assembly can have a flexible driveshaft that is rotatably translational with the lumen of the flexible sheath, a positive displacement pump that begins pumping at the distal end of the drive shaft adjacent to the helical flutes at the proximal end of the cutter, and the flexible drive shaft can be longer than the flexible sheath to enable a reversible telescoping of the drive assembly from the lumen of the flexible sheath. The positive displacement pump can be a screw pump having a drive screw portion extending beyond the flexible sheath, exposed for contact with a vascular lumen for the self-driving. And, the devices can have a reversibly-expandable, lateral pushing member at the distal end of the flexible sheath for the lateral pushing.

Telescoping atherectomy device

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.

Atherectomy devices and methods

A device for percutaneous venous valve repair generally including a catheter and a retractable and extendable member for deploying an object that affixes a portion of a venous valve leaflet to an adjacent vein wall. A related method for percutaneous venous valve repair is revealed to include percutaneously inserting a device as described herein into a peripheral vasculature of a living subject so as to affix at least a portion of a leaflet of a venous valve to an adjacent vein wall.

Atherectomy devices that are self-driving with controlled deflection

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.

Atherectomy apparatus, systems, and methods

Devices, systems, and methods are employed to restore patency to arterial lesions, e.g., by debulking restenosis in a blood vessel or within a stent or coil.

Improved automatic chest compression systems which use constricting belts, repeatedly inflating bladders, or reciprocating pistons to compress the chest. A bladder is placed between the chest and the particular mechanism used to compress the chest during CPR. The bladder maximizes the effectiveness of chest compressions.

CPR compression device and method

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.

Devices and methods for attaching a belt cartridge to a belt drive platform. A clip attached to the belt is inserted into a slot in the drive spool of the belt drive platform. The cover plate of the belt cartridge fits into a channel beam in the housing of the belt drive platform, thereby securing the cartridge to the housing. Belt guards, for protecting the cartridge, belt drive platform, patient and rescuer, are rotatably attached to the cover plate and are secured around spindles disposed on the sides of the housing.
