Abstract: Catheter (1) having a functional element (4) having at least a deployed configuration and an elongated configuration, the functional element (4) comprising filaments (5) and first (6a) and second (6b) connectors, the first connector (6a) connected to a first end (5a) of the filaments, and the second connector (6b) connected to a second end (5b) of the filaments, wherein in the elongated configuration, the first connector (6a) is at a distal end (d-e) of the functional element and the second connector (6b) is at a proximal end (p) of the functional element, and in the deployed configuration, the functional element is configured to act as a filter penetrable to fluid, the filaments forming turn-around points (5c) forming a distal end (d-d) of the filter, wherein the first connector (6a) is proximal to the turn-around points (5c), the catheter further comprising an actuator (7) configured to move the first connector (6a) proximally and to thereby facilitate transformation of the functional element (4) from the e

Abstract: The present disclosure relates to an aspiration system configured for aspiration of vascular debris from the vasculature, the system comprising a catheter comprising at least one or two lumen(s) configured for accommodating vascular debris and transporting vascular debris toward a proximal end of the catheter by way of suction, at least first and second ports in fluid communication with the lumen(s) and for entry of vascular debris from the vasculature into the lumen(s), wherein the first and second ports are located at a distal part of the catheter and are distanced from each other, and the system is configured to facilitate aspiration of vascular debris by agitating vascular debris by providing coordinated pressure pulses, optionally suction pulses, at the first and second ports.

Abstract: The invention refers to a catheter (51) for aspiration, fragmentation and removal of removable material from blood vessels. The catheter (51) comprises a flexible tube (52), a flexible helical transport screw (62) inside of the flexible tube (52), a stopper element (82) for providing an abutment for the distal end (64) of the flexible helical transport screw (62). The stopper element (82) is provided spaced from the distal end of the catheter (51), thereby defining a distal region (56) of the catheter (51) extending from the stopper element (82) in direction to the distal end of the catheter (51) which is free of rotational elements inside. A suction opening (74) for aspiration of the removable material into the inside of the flexible tube (52) is provided in the distal region (56) of the catheter (51).

Abstract: The present disclosure is directed to a catheter comprising a bendable catheter wall defining a substantially central interior lumen of the catheter, the catheter wall including a sealed chamber accommodating a fluid, the chamber substantially neighbouring the interior lumen and structured to be responsive to kinking of the catheter wall, the catheter further comprising a pressure sensor in fluid communication with the fluid, the pressure sensor configured to measure a pressure of the fluid, the pressure sensor further comprising an interface for communicating the measured pressure to a control unit, the catheter configured to allow for measurement of a change of the pressure in the fluid in response to kinking of the catheter.
