A connection device for a deflectable medical device, such as a catheter, comprises an elongate planarity wire having a proximal end and a distal end, an elongate activation wire having a proximal end a distal end, a passage and an interface. The passage extends through the planarity wire near the distal end of the planarity wire. The distal end of the activation wire extends through the passage. The interface is between the passage and the activation wire, and may comprise one or more of the following: a hook and bore interface, a detent interface, a mechanical interface, or a metallurgical interface.

Apparatus and method for connecting elements in medical devices

A sensor for a medical device including a plurality of sensor segments. Each of the plurality of sensor segments can include a layer of magnetically-permeable material and a layer of electrically-conductive material disposed on the layer of magnetically-permeable material. In an example, the layer of magnetically-permeable material can be arranged in a partially-annular shape. The sensor segments can include an electrical connection formation that extends transverse to the layers of magnetically-permeable material and electrically-conductive material. The electrical connection formation can be electrically coupled with the layer of electrically-conductive material. The plurality of sensor segments can be electrically coupled with each other through an electrical coupling of the respective layer of electrically-conductive material of each sensor segment with the electrical connection formation of another sensor segment.

Integrated sensors for medical devices and method of making integrated sensors for medical devices

An integrated electrode structure can comprise a catheter shaft comprising a proximal end and a distal end, the catheter shaft defining a catheter shaft longitudinal axis. A flexible tip portion can be located adjacent to the distal end of the catheter shaft, the flexible tip portion comprising a flexible framework. A plurality of microelectrodes can be disposed on the flexible framework and can form a flexible array of microelectrodes adapted to conform to tissue. A plurality of conductive traces can be disposed on the flexible framework, each of the plurality of conductive traces can be electrically coupled with a respective one of the plurality of microelectrodes.

High density electrode mapping catheter

The present disclosure relates generally to catheter devices, including irrigated and non-irrigated ablation catheters. More specifically, this disclosure relates to irrigated ablation catheters including an irrigation lumen having at least one electronic device at least partially disposed therein. In many embodiments, the irrigation lumen further includes at least one sideport. In some embodiments, the electronic device has a distal end extending out of the irrigation lumen and into an electrode tip assembly. In some embodiments, a proximal end of the electronic device extends through the sideport in the irrigation lumen.

Ablation catheter having electronic device disposed within a lumen

Methods of manufacturing and assembling a catheter shaft may include depositing electrical traces on an interior surface of the shaft of the catheter, rather than using separate wires, forming a bore in a sensor, and electrically coupling the sensor to the trace through a bore in the sensor.

Catheter shaft with electrically-conductive traces

The present disclosure relates generally to medical devices, and more specifically to ablation catheters including bond joints formed to have improved strength and resistance to failure during use. In many embodiments an expanded bond-joint length and area and gap filling are used to increase the strength of the bond joint while decreasing relative variability. The bond joint length area is increased in a controlled manner so as to increase the overall strength of the bond joint by shifting the failure mode from the bond joint to a stronger area of the ablation catheter, such as the catheter shaft. Related methods of manufacturing such ablation catheters (or other medical devices including a bond joint) are also disclosed and described herein.

Medical devices including high strength bond joints and methods of making same

Methods of manufacturing a sensor for a medical de vice may include the application of semiconductor fabrication techniques to the manufacture of a sensor directly in a structure of the medical device or in a substrate that can be integrated into a medical device structure. The methods may be applied to manufacture position sensors, strain gauges, other transducers, and the like, and to integrate the sensors into a variety of medical device types including, but not limited to, elongate medical devices.

A medical device for the diagnosis or treatment of tissue in a body and method for fabricating the same are provided. The device includes an elongate, tubular, deformable shaft comprising a proximal end and a distal end. The device also includes an electronic subassembly () disposed within the shaft and a conductor () coupled to and extending from the electronic subassembly. The electronic subassembly includes a flexible substrate () and an electronic device (). The flexible substrate comprises an interior side () and an exterior side () opposite the interior side. The flexible substrate also defines a first conductive area (). The electronic device is mounted on the interior side of the flexible substrate, is coupled to the first conductive area, and is at least partially enclosed within the flexible substrate.

Medical device with a packaged electronic subassembly and method for fabricating the same

An elongate medical device handle may comprise a body defining an interior, an exterior, and a connector port extending between the interior and the exterior and defining an axis. The connector port comprises a portion having a polygonal cross-section taken transverse to the axis. In an embodiment, the polygonal cross-section may comprise a star shape. In an embodiment, a connector, such as a fluid connector, may be secured in the connector port using an adhesive.
