A radiopaque lined heat shrinkable tubing is disclosed. A non-limiting example of a radiopaque lined heat shrinkable tubing is a multilayer construction having an inner layer and an outer layer, wherein the inner layer includes a thermoplastic that is highly loaded with a radiopaque filler, and the outer layer includes a fluoropolymer heat shrink tube.

Some examples of the disclosure are directed to medical balloon comprising a balloon base having an interior surface and an exterior surface, wherein the balloon base includes a base material (105), and one or more fibers (107) embedded within the base material. Some examples of the disclosure are directed to a medical balloon comprising a balloon base having an interior surface and an exterior surface, wherein the balloon base includes a base material (205), and one or more 3D printed fibers (207a) on a respective surface of the balloon base. Some examples of the disclosure are directed to manufacturing methods for forming one or more medical balloons.

Aspects of the invention relate to composite markers that employ a gel carrier to carry two or more contrast materials, each detectable by a detection modality different than one another. Kits and methods for forming these composite markers and methods of marking a target site in a mammalian subject employing these composite markers are also discussed herein.

A magnetic resonance compatible catheter. The catheter incorporates directional high intensity ultrasound. The catheter may include imaging coils visible through magnetic resonance imaging. The location and placement of the catheter may be controlled by steering wires within lumen in the catheter guided by the location information from the magnetic resonance imaging.

A coated medical device (10) including a structure (12) adapted for introduction into a passage or vessel of a patient. The structure is formed of preferably a non-porous base material (14) having a bioactive material layer (18) disposed thereon. The medical device is preferably an implantable stent or balloon (26) of which the bioactive material layer is deposited thereon. The stent can be positioned around the balloon and another layer of the bioactive material posited over the entire structure and extending beyond the ends of the positioned stent. The ends of the balloon extend beyond the ends of the stent and include the bioactive material thereon for delivering the bioactive material to the cells of a vessel wall coming in contact therewith. The balloon further includes a layer of hydrophilic material (58) positioned between the base and bioactive material layers of the balloon.

An embryo replacement catheter has a flexible extruded shaft of a transparent polyurethane with a bore extending along its length. Gas bubbles of a diameter in the range 5 to 10 are incorporated into the thickness of the wall of the shaft by adding gas during extrusion. The bubbles are selected to increase the visibility of the catheter under ultrasound imaging whilst still enabling material flowing along the catheter to be seen.
