A catheter includes an elongate shaft, an electrode assembly, a connective stem, a coupler, a first magnetic position sensor, and a second magnetic position sensor. The electrode assembly includes microelectrodes. The connective stem includes a first connective stem member and a second connective stem member. The connective stem defines a first sensor receptacle and a second sensor receptacle in an exterior surface of the connective stem. The coupler is configured for coupling with the connective stem. The first magnetic position sensor is disposed in the first sensor receptacle and elongated along a first sensor longitudinal axis. The second magnetic position sensor disposed in the second sensor receptacle and elongated along a second sensor longitudinal axis that is not parallel to the first sensor longitudinal axis.

Irrigated high density electrode catheter

A method of assembling a prosthetic heart valve includes providing a collapsible and expandable stent having an annulus section and an aortic section. The annulus section has a first diameter in a relaxed condition and a second diameter less than the first diameter in a collapsed condition. A constraint is applied to the stent to constrain the annulus section to a predetermined diameter between the first and second diameters. Applying a cuff and/or a plurality of leaflets to the stent in the constrained condition enables less material to be used. The resultant prosthetic valve is therefore able to be collapsed to a smaller diameter for introduction into a patient.

Valve assembly method for crimp profile

An apparatus for detecting relative positioning of medical devices located within a human body, the apparatus comprising an inner elongate member comprising a plurality of electrodes and a first sensor member, where the first sensor member is located a known distance from each of the plurality of electrodes, and an outer elongate member comprising a first sensor, and an outer sensor member located between the first sensor and an inner wall of the outer elongate member, where the inner elongate member is configured to move within the outer elongate member and the first sensor is configured to sense a signal generated by movement of the inner elongate member relative to the outer elongate member, and a position detection module including an electronic control unit configured to detect a position of the first sensor member relative to the first sensor based on the signal.

System and apparatus for detecting catheters relative to introducers

The present disclosure provides a means of holding, securing, or self-locking an actuating mechanism, such as a plunger-type or slide-type actuating mechanism, on a medical device having a deflected distal region using pinch points without the need for a secondary restraining or locking mechanism within the medical device. The present disclosure also provides a means to reduce the force experienced by a user during the deflection of a medical device such that use fatigue is lessened or eliminated. Various embodiments of the present disclosure are set forth herein.

Medical device including an actuator restraining assembly

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.

Magnetic sensor for tracking the location of an object

A position sensor used in medical devices for use with medical positioning systems. The position sensor includes a core () having a body and one or more projections () extending from the body, wherein the core comprises a high-permeability material. The position sensor further includes a coil () 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.

Core designs for miniature inductive coil sensors

Various embodiments of the present disclosure can include a catheter. The catheter can include an elongate shaft that extends along a longitudinal axis. The elongate shaft can include a shaft proximal end and a shaft distal end. A magnetically permeable shaft strip can be disposed along a particular shaft length of the elongate shaft. The magnetically permeable shaft strip can longitudinally extend along the elongate shaft.

Medical device sensor

A prosthetic heart valve for replacing a native valve includes a collapsible and expandable stent having a proximal end and a distal end, the stent being formed of a plurality of struts forming cells. A valve assembly is disposed within the stent, the valve assembly including a plurality of leaflets and a cuff. At least one runner is coupled to a cell and configured to transition from a first configuration to a second configuration when the stent moves from the collapsed condition to the expanded condition.

Valve assembly for crimp profile

An irrigated high density electrode catheter can comprise a catheter shaft. The catheter shaft can include a proximal end and a distal end and can define a catheter shaft longitudinal axis. A flexible tip portion can be located adjacent to the distal end of the catheter shaft. An irrigated coupler can be disposed on the distal end of the catheter shaft and can be configured to discharge fluid over the flexible tip portion.

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.
