An elongate medical device having an axis comprises an inner liner, a jacket radially outward of the liner, a braid comprising metal embedded in the jacket, a sensor, and at least one wire electrically connected to said sensor. The at least one wire is one of: embedded in the jacket and optionally disposed helically around the braid; extending longitudinally within a tube which extends generally parallel to the device axis and wherein the tube is embedded in the jacket; and disposed within a lumen, wherein the lumen extends longitudinally within the jacket.

Method of fabricating an elongate medical device

A medical device configured for diagnosis or treatment of tissues within a body is provided. The device includes an elongate, deformable member configured to be received within a lumen in the body and having proximal and distal ends. A position sensor is disposed at the distal end. In one embodiment, a conductor is wound about the member. The conductor is connected to the position sensor and has a first winding pitch over a first portion of the deformable member and a second winding pitch, different from the first winding pitch, over a second portion of the deformable member. In another embodiment, the member defines a neutral longitudinal axis extending between the proximal and distal ends. A conductor extending between the proximal and distal ends is connected to the position sensor at a connection node on the neutral axis.

Reducing mechanical stress on conductors and connection points in a position determinable interventional medical device

A medical device comprising a corewire, sensor core, and coupler is presented. A portion of the corewire is disposed within a first end of the coupler, and a portion of the sensor core is disposed within a second end. Alternatively, the device comprises a corewire and a sensor assembly comprising a sensor core having first and second ends and a bore in the first end. A portion of the corewire is disposed within the bore. A method of manufacture comprises providing a corewire, sensor core, and coupler. The method further comprises inserting a portion of the corewire into a first end of the coupler, and a portion of the sensor core into a second end. Alternatively, the method comprises providing a sensor core having first and second ends, and a corewire. The method further comprises forming a bore in the first end, and inserting the corewire into the bore.

Sensor mounted flexible guidewire

A male coupler for a guidewire, the guidewire having a hollow walled tube, the male coupler comprising a connector section, coupled with the guidewire, a portion of the connector section having a diameter smaller than the diameter of the hollow tube, at least one conducting ring coupled with the connector section where the diameter of the connector section is smaller the diameter of the guidewire, wherein the diameter of connector section and the at least one conducting ring substantially equals the diameter of the guidewire.

Guidewire interconnecting apparatus

A guidewire for a medical device is disclosed. In one embodiment, the guidewire includes a corewire having a proximal end portion and a distal end portion, an elongate shroud disposed about the corewire, the shroud having a distal end, and a plug coupled with the distal end portion of the corewire and the distal end of the shroud, the plug having a distal, non-traumatic tip portion, an interior between the corewire and the shroud being configured to receive a sensor.

Medical device guidewire with a position sensor

Method of assembling a positioning sensor and associated wiring on a medical tool

A flexible guidewire comprising a hollow tube, having a proximal section and a distal section, the distal section having a distal tip, the outer diameter of the distal section gradually decreasing toward the distal tip, the outer diameter of the distal tip being larger than the smallest outer diameter of the distal section, the flexible guidewire further comprising a plug coupled with the distal tip of the hollow tube for creating a non-traumatic tip, and the flexible guidewire further comprising a tubular spring, being place around the distal section of the hollow tube for maintaining the outer diameter of the hollow tube over the length thereof and for supporting compressive loads.
