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

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.
