Abstract: A medical device is provided comprising a shaft comprising a first segment and a second segment. The first segment is configured to buckle upon application of a first critical force. The second segment includes an outer surface and an inner surface and is configured to buckle upon application of a second critical force. The second critical force is lower than the first critical force. The medical device further comprises a coil disposed radially inwardly of the inner surface of the second segment.

Abstract: A deflectable medical device incorporates a strut that is configured to reduce or eliminate axial shortening of the deflectable portion of the medical device, for example, the deflectable distal end portion of a catheter or access sheath. The strut may is coaxially disposed in the medical device in the section that is contemplated to undergo the repeated deflection. The strut provides improved column strength and axial restoration. The strut may be stent-like device, an elongate device having opposing ends coupled by a connecting lattice involving a plurality of helical connecting elements or a tube having a plurality of circumferentially-extending slots arranged in longitudinally-extending rows.

Abstract: A circuit configured for connecting an electrode to a catheter or sheath is disclosed. The circuit includes a member having a longitudinal axis and configured to extend along at least a portion of the length of the catheter or sheath. The circuit further includes a trace printed on the member, where the trace includes at least a longitudinal segment extending generally along at least a portion of the longitudinal axis and a transverse segment extending generally transverse to the longitudinal axis. In an embodiment, the circuit further includes a pad integral with and extending from the circuit proximal the transverse segment of the trace. A catheter or sheath assembly comprising the circuit and an electrode connected to the circuit is also disclosed. A method of forming a catheter or sheath assembly is also provided.

Abstract: A method of manufacturing a catheter shaft includes extruding an inner polymeric layer having a main lumen and two or more side lumens spaced about the main lumen; forming an outer polymeric layer about the inner polymeric layer; and inserting at least one elongate member, such as a wire, through each side lumen of the inner polymeric layer. The side lumens are less than about 1/5 the size of the main lumen. The method may further include the step of forming a braided layer between the inner polymeric layer and the outer polymeric layer. In an alternate embodiment, the method includes co-extruding an inner polymeric layer and a multi-lumen layer, the multi-lumen layer having two or more side lumens; forming an outer polymeric layer about the multi-lumen layer; and inserting at least one elongate member through each side lumen. Catheter assemblies made according to the described methods are also disclosed.
