Abstract
Official abstract text for this publication.
A fibrin removal assembly includes a single helical coil with a plurality of windings. A plurality of cutting elements extends from the windings into the lumen of the coil. Each of the cutting elements has a cutting edge, and all cutting edges point in a blade direction relative to a circumferential direction that promotes a penetration of tissue by the cutting elements in a cutting direction about the longitudinal axis and evading in a rotational direction opposite to the cutting direction. The cutting elements may further have a dull edge acting as radially inward ramps for tissue during a rotation in the second rotational direction. The windings may be wound in a direction that translates into a proximal movement of the coil when the coil is rotated in the cutting direction and into a distal movement when the coil is rotated opposite to the cutting direction.
First claim
Opening claim text (preview).
What is claimed is: 1. A fibrin removal assembly comprising: a single helical coil having a plurality of windings defining a longitudinal lumen with a central longitudinal axis, and a plurality of cutting elements formed in one piece with the helical coil and extending from the windings into the lumen, each of the cutting elements having a cutting edge extending into the lumen, all cutting edges pointing in a blade direction relative to an circumferential direction, the blade di…
