The application relates to an arteriovenous fistula vein segment maturation rate improvement system, comprising: a catheter delivery system comprising: a catheter; first and second seals; the catheter and the first and second seals are configured to be positioned within a lumen of a vein segment to be treated; an angioplasty device for expanding a lumen of a vein segment; a first volume of brine; and a second volume of fluid, the fixative solution promoting cross-linking of proteins of the vein segment; the catheter delivery system is configured to deliver the fixative solution through the one or more ports to the space between the first and second seals after delivery of the first volume of saline and occupy the space for a predetermined time to crosslink proteins of the vein segment, and to deliver the fixative solution through the one or more ports to the first and second seals after delivery of the first volume of saline. And aspirating the fixative solution from the space through one or more ports after a predetermined time to prevent vascular injury response due to balloon angioplasty performed by the angioplasty device, thereby improving the maturation rate of the vein segment of the arteriovenous fistula.

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.

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.
