Abstract: An assembly for driving movement of an elongate surgical tool, comprising: a plurality of adjacent pairs of driving wheels, each pair of driving wheels having a space therebetween such that spaces of the plurality of pairs of driving wheels are axially aligned to form a channel for the elongate surgical tool to extend through; wherein at least one pair of driving wheels out of the plurality of pairs is arranged to lie on a plane different than a plane on which at least one other pair of driving wheels lies.

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 compact robotic device for driving movement of two or more elongate surgical tools configured for a telescopic arrangement when said two or more elongate surgical tools are at least partially received within said device, the device comprising: a housing comprising walls which define an inner volume including at least two inner pathways for accommodating the two or more elongate surgical tools; the housing encasing: a plurality of motors, and two or more tool actuation assemblies configured at a position of each of the two or more inner pathways; the actuation assemblies driven by the plurality of motors and configured to operably contact an elongate surgical tool at least partially received in the inner pathway to at least one of advance, retract and/or roll said elongate surgical tool.

Abstract: An assembly for driving linear movement and roll movement of an elongate surgical tool, comprising: an elongate shaft comprising a central lumen extending along the shaft long axis; the elongate shaft comprising a plurality of apertures extending across walls of the elongate shaft and into the central lumen; a set of wheels positioned opposing each other and aligned on two sides of the central lumen, the set of wheels at least partially extending through the apertures beyond the walls of the elongate shaft and into the central lumen to contact an elongate surgical tool received therein; the set of wheels being coupled to the elongate shaft and configured to rotate with the elongate shaft as a single unit when the elongate shaft is rotated about the shaft long axis.

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: 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.
