A deflectable catheter shaft section is disclosed comprising an elongated body extending along a longitudinal axis with a distal end and a proximal end. First and second pull wires can extend along the elongated body and can have a proximal end and a distal end. First and second pull wire liners can be disposed over a portion of one of the first and second pull wires, respectively. Each of the first and second pull wires can have a proximal end and a distal end. A first gap can exist between the proximal end of the first pull wire liner and the proximal end of the elongated body and a second gap can exist between the proximal end of the second pull wire liner and the proximal end of the elongated body.

Deflectable catheter shaft section

An elongate medical device shaft may comprise an elongate body and an annular electrode disposed on the elongate body. The annular electrode may define a longitudinal axis and have an outer diameter. The outer diameter may be greater at an axial center of the electrode than at an axial end of the electrode. Additionally or alternatively, the elongate body may comprise three longitudinal sections having three wall thicknesses. The middle wall thickness may be less than the proximal and distal wall thicknesses and the distal wall thickness may be less than the proximal wall thickness. Additionally or alternatively, the shaft may comprise an inner cylindrical structure and an outer tube. The outer tube may comprise a first radial layer and a second radial layer that is radially-outward of the first radial layer, the first radial layer, second radial layer, and inner structure having different stiffnesses.

Elongate medical device including chamfered ring electrode and variable shaft

Improved hand assemblies and methods combining a number of the separate known devices used in transseptal catheterization procedures, including sheaths, dilators, and needle assemblies (including a puncture device and a stylet, for example). The hand assemblies provide cooperating members that reduce the overall complexity and increase safety of transseptal catheterization procedures.

Transseptal catheterization assembly and methods

The invention encompasses a catheter having an outer surface, a distal end, and at least one interior lumen, wherein the outer surface includes multiple aspiration passageways in fluid communication with an interior lumen. A preferred embodiment comprises multiple aspiration passageways formed into a helical pattern.
