Abstract: Methods of forming a cutting element include leaching a diamond table of the cutting element and subsequent to leaching the diamond table of the cutting element, forming a chamfer on the diamond table of the cutting element at an interface between a cutting surface of the diamond table and an outer side surface of the diamond table. Methods of forming earth-boring tools include forming a cutting element and securing the cutting element to a body of the earth-boring tool. Forming the cutting element includes including leaching a diamond table of the cutting element and subsequent to leaching the diamond table of the cutting element, forming a chamfer on the diamond table of the cutting element at an interface between a cutting surface of the diamond table and an outer side surface of the diamond table.

Abstract: A multicatheter subsystem is provided for a steerable catheter robotic system. The subsystem includes a flexible output sheath, a plurality of flexible multi-lumen assemblies and a plurality of robotic instruments for performing a surgical procedure. The plurality of flexible multi-lumen assemblies extends through the outer sheath. Each of the multi-lumen assemblies has a proximal end and a distal end. Each of the robotic instruments is operatively and removably attachable to the distal end of one of the multi-lumen assemblies such that each instrument is teleoperable independently of every other robotic instrument. At least a first of the robotic instruments includes a plurality of interconnected articulating segments. Each of the articulating segments is operatively and removably attachable to a different one of the multi-lumen assemblies.

Abstract: A surgical arrangement includes an endoscope having an insertion tube with an imaging system disposed on its distal end and at least one instrument channel extending therethrough. A catheter subsystem of a steerable catheter robotic system is removably insertable into the instrument channel. The catheter subsystem includes a flexible outer sheath having a proximal end and a distal end. At least one flexible multi-lumen assembly extends through the outer sheath. The multi-lumen assembly has a proximal end and a distal end.
