Abstract: An apparatus for emitting a field comprising a core, a conductive winding with a first end, a second end, and an intermediate portion, where the conductive winding surrounds a portion of the core and is wound about a winding axis, a protrusion for aligning the apparatus where the protrusion is parallel with the winding axis, and a conductive connector extending from the conductive winding, wherein the conductive connector is electrically coupled with the conductive winding at the intermediate portion.

Abstract: A position sensor used in medical devices for use with medical positioning systems. The position sensor includes a core (80) having a body and one or more projections (841,842) extending from the body, wherein the core comprises a high-permeability material. The position sensor further includes a coil (74) surrounding the body, wherein the coil is configured to generate a voltage when subject to a magnetic field. The one or more projections extending from the body of the core are configured to concentrate the magnetic field into the coil and increase the voltage. Thus, various core designs are described which have projections which may increase the electrical and/or mechanical integrity of the position sensor and/or which may also induce magnetic flux flow within the position sensor thereby increasing the signals generated by the position sensor.

Abstract: A sensor may include a core and a coil. The core may include a rectangular substrate, a layer of magnetically-permeable material disposed on the substrate, and an adhesive rigidly coupling two ends of the substrate so as to form a tube with the rectangular substrate. The coil may be wound on the tube. The core may further include a layer of radiopaque material. The core may further include a flex pad for electrically coupling the coil with an external system.

Abstract: 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.
