Catheter for laser-assisted removal of undesired tissue
The patent US12042223B2 outlines a method for removing undesired tissue from a vessel using a specialized catheter equipped with a tip section that integrates both laser and aspiration systems. The method involves generating an aspiration force through an aspiration lumen to remove the undesired tissue while simultaneously transmitting laser energy from the catheter's tip. This laser energy, which can be configured to modify the biological characteristics of the tissue, is delivered through optical elements, such as a plurality of optical fibers. The catheter's design ensures that the cutter, which detaches the tissue from the vessel wall, is positioned outside the laser's optical path, allowing for precise operation. The method also includes monitoring the treatment process and controlling the detachment and removal of the tissue based on real-time feedback.
Further details of the method specify the characteristics of the laser energy, including a wavelength of approximately 355 nm, pulse widths of 10 nanoseconds, and power levels ranging from 30 to 60 mJ/mm². The system is designed to operate with a pulse frequency of 10-100 Hz and energy per pulse between 10-100 mJ. The catheter's tip section features a dual-blade cutter, with the optical fibers positioned between the inner and outer blades, enhancing the efficiency of the tissue removal process. The method emphasizes the importance of monitoring and controlling the treatment to ensure effective removal of the undesired tissue while minimizing damage to surrounding structures.
