Latest Patents
One of Troein's latest patents is the "Percutaneous Venous Catheter." This innovative catheter features a first fluid-pervious segment for implantation in the body and a second extravascular segment made of a flexible tube surrounded by a vapor-barrier sheath. A cuff marks the boundary between the two segments, and a connector fitting is mounted to the free end of the extravascular segment, ensuring a continuous fluid path between the fitting and the tip. The vapor barrier in the extravascular segment prevents fluid transpiration through the catheter wall, which can lead to occluding thrombus formation at the catheter tip.

It includes a rigid base with a flat undersurface and a low profile, supporting one end of a needle that projects perpendicularly from the base. A flexible tube is secured to the base in fluid communication with the needle, and the opposite end of the tube is terminated by a connector. The set also features a compliant pad mounted to the base undersurface to ensure proper seating against the patient's skin during insertion.
