A medical device for the diagnosis or treatment of tissue in a body and method for fabricating the same are provided. The device includes comprises a first shaft and a second shaft. The first shaft includes a longitudinal axis, and the second shaft includes a second shaft axial end disposed within the first shaft. The second shaft is connected to the first shaft by a first nested lap joint formed between the first shaft and the second shaft.

A deflectable catheter shaft with compression resistance coils configured to create different curve shapes when the catheter is steered or deflected in different directions. One or more compression resistance coils may include an elongated-pitch section. The compression resistance coils may be pull wire compression coils or body compression coils.

Asymmetric catheter curve shapes

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.

The present disclosure provides a guide wire system comprising (a) a guide wire having a distal end and a proximal end, wherein the guide wire comprises a superelastic material, (b) a first connector coupled to the proximal end of the guide wire, (c) a second connector coupled to the guide wire between the distal end and the proximal end, (d) an electromagnetic sensor coupled to the distal end of the guide wire, and (e) a polymeric tube surrounding the guide wire and at least a portion of the electromagnetic sensor.

Image guided surgery system guide wire and methods of manufacturing and use

A medical device is configured for diagnosis or treatment of a tissue within a body. The medical device comprises an elongate member and a position sensor. The elongate member is configured to be received within the body, and has a lumen extending between a proximal end and a distal end. The position sensor is disposed within the lumen proximate the distal end of the deformable member. The position sensor comprises a coil wound to form a central passage and configured to generate a current flow when subject to a magnetic field, and a high-permeability antenna having at least a portion disposed outside the central passage to concentrate the magnetic field into the coil and increase the current flow.
