    摘要: A catheter system (100) for treating a treatment site (106) within or adjacent to a vessel wall (108A) of a blood vessel (108) within a body (107) of a patient (109) includes an energy source (124), a catheter fluid (132), and an emitter assembly (129). The energy source (124) generates energy. The emitter assembly (129) includes (i) at least a portion of an energy guide (122A) having a guide distal end (122D) that is selectively positioned near the treatment site (106), (ii) a plasma generator (133), and (iii) an emitter housing (260) that is secured to each of the energy guide (122A) and the plasma generator (133) to maintain a relative position between the guide distal end (122D) of the energy guide (122A) and the plasma generator (133). The energy guide (122A) is configured to receive energy from the energy source (124) and direct the energy toward the plasma generator (133) to generate a plasma bubble (134) in the catheter fluid (132). The plasma generator (133) directs energy from the plasma bubble (134) toward the treatment site (106).

    摘要: Provided is a laser ablation catheter, including a laser optical fiber bundle, an adjustable head, an outer tube, an overtube and a connector. The outer tube wraps the laser fiber bundle. The adjustable head includes an adjustable stent, the adjustable stent is made of a shape memory material and is sleeved outside one end of the outer tube. The connector is connected to the other end of the outer tube, and the laser fiber bundle can be connected to a laser generator through the connector. The overtube is sleeved outside the adjustable stent for compressing the adjustable stent. At least one end of the adjustable stent is a movable end, and the movable end is slidingly connected to the outer tube. When the overtube is withdrawn, the movable end can provide conditions for the deformation of the adjustable stent.

    摘要: The present disclosure relates to a fat-removing surgical instrument. The present disclosure additionally arranges/provides, on a lipolyzed fat suction passage of a wave-guide tube, an optical fiber support which is made from an insulating material and which supports optical fibers in a restrained state while fixed to the wave-guide tube, so that the optical fibers are prevented from being deformed and coming in contact with the wave-guide tube, and thus, the optical fibers are induced, even though a variety of factors (for example, weight, contact with human tissue and the like) are applied to the optical fibers during fat removal surgery, to effectively avoid coming in direct contact with the wave-guide tube and being damaged thereby, while a series of deformations (for example, a curved shape and the like) are inhibited/controlled, on the basis of forceful restraint of the optical fiber support.
