Publication number: 20240058059Abstract: Systems for enabling delivery of very high peak power laser pulses through optical fibers for use in ablation procedures preferably in contact mode. Such lasers advantageously emit at 355 nm wavelength. Other systems enable selective removal of undesired tissue within a blood vessel, while minimizing the risk of damaging the blood vessel itself, based on the use of the ablative properties of short laser pulses of 320 to 400 nm laser wavelength, with selected parameters of the mechanical walls of the tubes constituting the catheter, of the laser fluence and of the force that is applied by the catheter on the tissues. Additionally, a novel method of calibrating such catheters is disclosed, which also enables real time monitoring of the ablation process. Additionally, novel methods of protecting the fibers exit facets are disclosed.Type: ApplicationFiled: August 30, 2023Publication date: February 22, 2024Applicant: Eximo Medical Ltd .Inventors: Yoel ZABAR, Oren Meshulam STERN, Ilan BEN OREN

Publication number: 20230149033Abstract: Systems and methods for dynamically modulating aspiration in response to sensed conditions. An aspiration system can include a catheter configured to be inserted within a vasculature of the subject, a canister coupled to the catheter, a pressure source that generates a vacuum pressure through the catheter for aspirating the fluid, a sensor configured to sense a parameter associated with at least one of the catheter, the canister, or the pressure source, and a computer system coupled to the sensor. The computer can cause the pressure source to initiate the vacuum pressure throughout the catheter, receive a measurement of the parameter from the sensor, determine whether the measurement violates a threshold associated with the parameter, and modulate the vacuum pressure at the catheter tip in response to a determination that the measurement violates the threshold.Type: ApplicationFiled: November 16, 2022Publication date: May 18, 2023Applicant: Eximo Medical Ltd.Inventors: Yoel ZABAR, Ilan BEN OREN, Oren Meshulam STERN, Eitan Yaacov POLLACK

Publication number: 20200237440Abstract: New devices and methods for deflecting a catheter progressing within a lumen, into a preferred direction, typically in order to accomplish ablative removal of obstructive material within that lumen without the danger of uncontrolled catheter deflection risking perforation of the lumen. The catheter may ride on a guide wire, or it may be free riding down the lumen, limited by the passages available in the obstructive material, and generating its own passage by debulking the material within the lumen. The types of deflection required may be radial or lateral. A number of novel configurations are described, including improvements to the slotted wall catheter, by selection of the shape, spacing and location of the slots. Other implementations include a catheter with a novel spring configuration, which can release itself from a situation in which the catheter becomes stuck when widening an initial narrow bore in an obstructed vessel.Type: ApplicationFiled: April 3, 2020Publication date: July 30, 2020Applicant: EXIMO MEDICAL LTDInventors: Yoel ZABAR, Ilan BEN OREN, Oren Meshulam STERN, Shay GRANOT
