Rotatable catheter device for crossing occluded vessel with guidewire
A newly granted patent (Publication Number: US11998311B2) discloses a catheter device designed for positioning a guidewire across a blocked section of a vessel. The catheter device features a catheter body with a central lumen and a steerable distal region that can bend laterally towards a specific side. The distal end of the catheter body includes spiral-shaped wedge members, with a driveshaft inside the central lumen that can rotate and extend a distal tip with cutting edges. The cutting edges align with the spiral shape of the wedge members when extended, allowing for precise cutting of blockages. The device can lock the distal tip in an extended position and bend the catheter body upon pushing the driveshaft longitudinally.
Additionally, the catheter device includes a handle for controlling the lateral bending of the catheter body and the extension/retraction of the distal tip. The handle features controls for rotation of the driveshaft and the distal tip, with indicators to show the extent of extension. The device can also lock the catheter body in a bent or straight configuration, with a luer connector for accessing the lumen. The method associated with the device involves advancing it through the vessel towards the blockage, extending the distal tip to expose cutting edges, rotating the tip to cut the blockage, and using a pushing force to steer the tip across the vessel while positioning the guidewire. The method also includes delivering fluid to the desired area within the vessel through the catheter device's lumen and locking the steerable distal region in a bent configuration by restricting the driveshaft's movement.
