Catheter device for guidewire positioning in occluded vessels
The patent US11998311B2 describes a catheter device designed for positioning a guidewire across an occluded portion of a vessel. The device features a catheter body with a central lumen and a steerable distal region that can bend laterally. The distal end of the catheter includes spiral-shaped wedge members, and a driveshaft within the lumen is capable of rotating and moving longitudinally. This driveshaft is connected to a distal tip equipped with one or more cutting edges arranged in a spiral pattern, which aligns with the wedge members when extended. The device allows for locking the distal tip in an extended position and is designed to bend toward a predetermined side when a longitudinal force is applied.
Additionally, the catheter device includes a handle that facilitates control over the lateral bending of the catheter body and the extension and retraction of the distal tip. The handle may feature controls for rotation and longitudinal movement, with specific components for sliding and rotating actions. The device can be motor-driven, allowing for clockwise and counterclockwise rotation of the distal tip. The method outlined in the patent involves advancing the catheter through a vessel, extending the distal tip to expose the cutting edges, and rotating the tip to cut through the occlusion while steering the device. The catheter also allows for fluid delivery through its lumen and includes mechanisms for locking the steerable region in a bent configuration, enhancing its usability in medical procedures.
