ROSES SYSTEM FOR ENDOVASCULAR SURGERY

This document illustrates all the new features of the ROSES system (RObotic System for Endovascular Surgery) which Is extended by angioplasty to all possible endovascular applications, starting with the increase in size of the passage hole through the RA to allow not only thrust, of catheters and stents of large diameter, but even the passage of hemostatic valves, and then move on to the description of disposable catheters and guides not for angioplasty, then moving on to the RA handling trolley which also allows the measurement of the forces that the organism of the patient opposes the advancement of the catheters, but even that which meets the guide in the advancement inside the catheter. The curvature control system of a catheter is then illustrated, ending with the definition of a new family of RAs that can control two independent rotations and four further independent parameters.

The invention relates to a tube (100) with a hollow cylindrical elastic base structure (102) for insertion into a blood vessel (200) of a vascular system (202). The tube (100) comprises an outer anisotropic surface structure (104) comprising a geometrical anisotropy between a direction circumferential to the tube and a direction longitudinal to the tube (100). The anisotropic surface structure (104) is configured for establishing an anisotropic friction between the anisotropic surface structure (104) and an inner surface of the blood vessel (200). The anisotropic friction results in a surface propulsion of the tube (100), when the tube (100) is rotated around a central longitudinal body axis (106) of the tube (100). The tube (100) further comprises a magnetic material (108) distributed circumferentially around the tube (100) and configured for establishing within an external magnetic field a rotation of the tube (100) around the central longitudinal body axis (106) of the tube (100).

Systems and methods for guidance of intraluminal devices within the vasculature

System for guiding an instrument within a vascular network of a patient are disclosed. In some embodiments, the system receives a medical image from a medical imaging device and identifies a distal tip and a direction the instrument in the image. The system may then determine a waypoint for the distal tip of the instrument based at least in part on the position and direction of the distal tip of the instrument. The system may then generate a trajectory command for moving the instrument through the vascular network from the current position to the waypoint. The system may operate in a closed loop. The system may provide the trajectory command to a robotic medical system configured to move the instrument according to the command.
