Embodiment Construction

[0037] The devices, systems and methods of the present invention provide improved means and methods for oscillating a drilling member to recanalize complete or partial blockages in blood vessels, but may also be applied to clear blockages from other body lumens. The device of the invention comprises a spring member and a drill member at the distal end of the catheter, for example in the tip of the catheter, and a pulling member attached to the spring member or drill member and housed in the catheter. The apparatus provides therapeutic vibrations in the drilling member at the distal end of the catheter, ie in the catheter tip. The vibratable drilling member is operatively attached to the distal end of the spring member. Vibration of the drilling part is achieved by means of the spring member by pulling and releasing the pulling member.

[0038] More specifically, when pulled, the pulling member (which may be attached to the spring member or the drilling member) may compress th...

Abstract

An apparatus, system and method for re-canalization or opening a passage through an occlusion in a blood vessel is provided. The apparatus and method, which are appropriate for cardiovascular and peripheral vessels, use a pulling member and a spring member, for example a compression spring, to oscillate a drilling component. The drilling component at the distal end of the catheter tip has combined longitudinal stiffness for penetrating a total or partial occlusion and high axial (lateral) flexibility to improve deliverability and crossability of a catheter through a partially occluded vessel or a tortuous vessel, and may taper distally. The system of the invention includes the apparatus and a control unit to permit adjustment of the frequency or amplitude of oscillation of the drilling component. Also provided is a method for oscillating a drilling component using a pulling member and a spring member and a method of traversing an occlusion.

Description

technical field [0001] The present invention relates to a system for penetrating a complete occlusion of a blood vessel during percutaneous coronary intervention (PCI) or for improving the delivery capability of a percutaneous transluminal angioplasty (PTA) catheter through a partial occlusion of a blood vessel Energy-saving devices and methods of using the same. In particular, the device provides effective energy transfer to the distal end of the device by means of pulling force, so as to penetrate the obstruction with minimal energy loss, the device provides a distal end section combined with a Longitudinal stiffness to penetrate the obstruction and axial flexibility (or flexibility) for delivery capability. The device can also be applied in percutaneous interventional procedures in peripheral arteries. Background technique [0002] Effective treatments for disease conditions involving narrowing (narrowing or blockage) of the lumen of arteries have long been sought by me...
