Abstract: An adaptor for coupling a proximal portion of an elongate surgical tool to a motorized robotic surgical device, the adaptor comprising: a recess shaped and sized for receiving a proximal portion of an elongate surgical tool; one or more movers positioned to contact and move a control component of the proximal portion; and transmission coupling which couples the one or more movers to motorized transmission of the robotic surgical device.

Abstract: A modular robotic surgical system comprising: a base; a plurality of tool-receivers arranged as separate units, each tool-receiver unit operable to move an elongate surgical tool received therein; a plurality of interface coupling pairs, each coupling pair comprising a first coupler as part of the base and a second coupler as part of each of the tool-receiver units; wherein each of the tool-receiver units is independently and interchangeably attachable to the base via the coupling pair.

Abstract: A modular robotic surgical system includes one or more tool-receiver units arranged as separate units, each tool-receiver unit operable to move a first elongate surgical tool received therein. The device also includes a base comprising one or more motors, the base operable to move a second elongate surgical tool attached to the base or received therein, the base serving as a mounting for the one or more tool-receiver units, each of the tool-receiver units is independently and interchangeably attachable to the base via a mechanical coupling interface which transfers one or more of: driving force for driving movement of the first elongate surgical tool received within the unit; electrical power supply to one or more components of the unit which drive movement of the first elongate surgical tool received within the unit; and data for controlling movement of the first elongate surgical tool received within the unit.

Abstract: Disclosed is a self-cleaning catheter system for fluid passage including a catheter, configured to be implanted in a body cavity of a subject and including at least one aperture fluidly coupling the catheter to the outside thereof, a cleaning unit configured for motion in the catheter such as to at least one of mechanically prevent, remove and mitigate occlusion in the at least one aperture, and an implantable controller. The cleaning unit is functionally associated with the controller, which is configured to (i) receive at least one signal indicative of a state of occlusion in the catheter, and (ii) provide an indication of the state of occlusion at least if the at least one signal indicates a blockage in the catheter and/or (iii) activate the cleaning unit if the at least one signal indicates a blockage of the catheter.

Abstract: A method and a kit for the prevention of venous stenosis associated with the use of hemodialysis AV shunts. The kit may use a bifurcated needle for providing access to the shunt or blood vessel. One of the arms is used for returning the blood to the subject after dialysis treatment, while the other arm is used for inserting a device for cleaning the vein, the device being either an autonomous crawling device, or a passive tethered device moved down the vein by the blood flow. The autonomous crawling device may be a series of sequentially inflatable chambers, the stenosis being cleared by pressure from the outer walls of the chambers when inflated and moved. The passive device may be an element having a flexible disc-like structure, whose flexible peripheral edge slides along the inner walls of the blood vessel, compressing or clearing the material attached thereto.
