Provided is a traction device for curved balloon catheter, which is characterized by comprising: a catheter () with a handle () at one end, a locator () and a traction balloon () arranged outside the catheter (), which one or more cavities are arranged in the catheter (), the catheter part is provided with at least one hole, at least one cavity fills and discharges the traction balloon () with fluid through the hole, the traction balloon () bends to one side when filled with fluid, and the handle () can drive the catheter () and the traction balloon () to rotate, thus realizing a simple and reliable traction.

Traction device for curved balloon catheter and traction method

A sensing guidewire device used to measure physiological parameters within a living body. In one embodiment, the device is used to measure the fractional flow reserve (FFR) across a stenotic lesion in a patient's vasculature. The device includes a sensor that is adapted to be affixed near the distal end of a guidewire. The guidewire contains a corewire, processed to enclose electrical conductors in a sealed, off-centered interstice or channel, with an outer diameter approximate to the outer diameter of the device, running substantially the full length of the device, and has a homogenous outer surface. The enclosed eccentric channel provides space for electrical conductors to move freely. The corewire can have a tapered segment to create desirable flexibility. A solid connector comprised of alternating conductive and insulating elements for connecting the conductors to an external device is disclosed. The guidewire can be advanced through a patient's blood vessels, returning pressure measurements across vessel blockages that allow for accurate assessment of blockage severity and lead to better clinical outcomes.
