Atherectomy-angioplasty devices, systems, and methods reduce the device costs, procedure times, and risks associated with clinician error and patient trauma that accompany separate atherectomy and angioplasty devices. An example atherectomy-angioplasty device includes a tubular body, an elongate rotor, a plaque-debulking element, and an elongate balloon. The tubular body includes a rotor lumen and an inflation lumen. The elongate rotor is disposed in the rotor lumen. The plaque-debulking element is configured to debulk atherosclerotic or restenotic plaques in a blood-vessel lumen of a patient. To do so, the plaque-debulking element is actuated by the elongate rotor when the elongate rotor is rotated around its longitudinal axis in the rotor lumen. The elongate balloon is over a distal portion of the tubular body. The elongate balloon is fluidly connected to the inflation lumen for inflating or deflating the elongate balloon, as desired, for preventing dispersion of atherosclerotic debris, angioplasty, or both.

The present invention can mechanically prop up or loosen a blood vessel; and through the axial shock wave generating electrode pair and the circumferential shock wave generating electrode pair, occluded plaques can be opened in the forward direction, and shock waves can be emitted in the circumferential direction to lyse or break up calcium deposits; and broken calcified plaques or aortic plaques and thrombi can also be captured.

A venting device (1; 101) is disclosed which can be connected to or is connected to a balloon catheter (2) of an angioplasty device (3), wherein the venting device (1; 101) has an inflation syringe (22) by means of the plunger (22a) of which pressurised fluid (6) can be displaced from a syringe cylinder (22b) of the inflation syringe (22), and wherein air (4) can also be drawn from the balloon catheter (2) into the syringe cylinder (22b) and displaced from it by means of the plunger (22a). The inflation syringe (22) is automatically rotatable or permanently arranged in a first position in which a tip (22e) of the inflation syringe (22) is directed upwards in such a way that in the first position an air collection area (26) for the air (4) aspirated from the balloon catheter (2) can be generated or is already generated in the syringe cylinder (22a) of the inflation syringe (22) adjacent to the tip (22e) and directly below the tip.Also revealed is an angioplasty device (3) with such a venting device (1; 101).

An angioplasty system is provided. The system comprises an inflation device for angioplasty devices within a blood vessel presenting stenosis, and includes a contrast fluid reservoir with a pressure-adjusting device; a connector; a pressure sensor; an electronic-actuation valve; safety features; powering features; a digital interface; a microprocessor with a first software; a memory; a connection of the microprocessor to the Internet or an intranet; a second artificial intelligence software; a database; and a radiological arch to acquire and process images of the blood vessel or the area where the blood vessel is located. The microprocessor is connected to the radiological arch and to the database, in such a way that the inflation device may learn to operate autonomously and adjust itself automatically taking into account previous data or treatment models.
