Abstract: A medical tool may comprise a sheath and an elongate instrument. The sheath may comprise a tubular shaft member including a sheath channel and a guard member coupled to a distal portion of the tubular shaft member. The guard member may comprise a rigid distal section and a flexible proximal section that is more flexible than the rigid distal section. The elongate instrument may be sized for passage within the sheath channel. The elongate instrument may comprise a flexible tubular section and a rigid tip extending from a distal portion of the flexible tubular section.

Abstract: A medical tool comprises an elongated tubular section comprising a body wall. The body wall includes a plurality of slits. The tool further comprises a rigid needle tip coupled to a distal end of the elongated tubular section. The tool further comprises a flexible jacket covering at least a portion of the elongated tubular section. The tool further comprises an elongated flexible member coupled to a proximal end of the elongated tubular section. A distal portion of the elongated flexible member covers a proximal portion of the flexible jacket, and a proximal portion of the elongated flexible member extends into at least a portion of the plurality of slits.

Abstract: A catheter system may comprise an articulation joint including a first pair of links and a second pair of links. Each link may include a central channel enclosed at least in part by radially extending arcuate segments. The first pair of links may include a first link and a second link, and the second pair of links may include the second link and a third link. The system may also comprise a first pair of springs coupled between the first and second links. The system may also comprise a second pair of springs coupled between the second and third links. The system may also include control wires extending through the first pair of springs and a control wires extending through the second pair of springs. The spring walls may share a radial dimension with the link walls.

Abstract: A system may comprise a catheter including a wall having an inner surface defining a main lumen. The system may also comprise a device including an elongate flexible shaft configured to be slideably inserted within the catheter main lumen and a structure disposed around an outer surface of the elongate flexible shaft. The structure may be configured to engage with a plurality of flat surfaces comprising a portion of the inner surface to prevent rotation of the device within the main lumen.

Abstract: A medical device comprises an elongate sheath defining a first lumen and comprising a distal portion and a flexible proximal portion. The medical device further comprises an elongate instrument slidably disposed at least partially within the first lumen. The elongate instrument comprises a flexible tubular proximal section and a rigid distal section defining a second lumen. The medical device further comprises an instrument handle coupled to a proximal end of the elongate instrument. The medical device further comprises a sheath handle coupled to a proximal end of the elongate sheath. The sheath handle is configured to at least partially receive the instrument handle. The medical device further comprises a holding mechanism coupled to the sheath handle. The holding mechanism is rotatable to engage the elongate instrument to maintain the rigid distal section of the elongate instrument in an extended position from the distal portion of the elongate sheath.
