Catheter for removing tissue from blood vessels using lasers
The patent US12042223B2 outlines a method for removing undesired tissue from a vessel using a specialized catheter equipped with a tip section and an aspiration lumen. This method integrates a laser system and an aspiration system to effectively detach and remove tissue. The process begins with generating an aspiration force to draw the undesired tissue into the catheter. Concurrently, laser energy is transmitted from the catheter's tip, utilizing optical elements that modify the biological characteristics of the tissue. The design ensures that the cutter, which detaches the tissue, is positioned outside the laser's optical path, allowing for precise operation. The method also includes monitoring the treatment and controlling the detachment and removal of the tissue based on real-time feedback.
Further details of the method reveal that the optical elements may consist of multiple optical fibers arranged parallel to the catheter's central axis, with the laser energy characterized by specific wavelengths and pulse parameters. The cutter is designed with inner and outer blades, potentially coated to enhance sharpness, and is strategically placed to ensure effective detachment of the modified tissue. The method emphasizes the importance of monitoring throughout the procedure, allowing for adjustments to the laser energy and aspiration as needed. This innovative approach aims to improve the efficiency and safety of tissue removal in medical procedures.
