Systems, methods and devices are described including a catheter adapter subassembly including a magnetic feature. Systems include such a catheter adapter subassembly and a needle subassembly including a magnetic feature, and relative movement of the catheter adapter subassembly and the needle subassembly can be determined using a magnetometer.

A process for coating parylene onto a metal surface, such as a medical device, that has been textured by a series of laser pulses. The laser pulses can be overlapping or rastered. The textured portion of the metal surface and parylene coating can form a strong mechanical interlock. The bond created by using the laser texturing process can result in a cohesive failure of the parylene and not an adhesive failure of the bonding.

A medical device and a method and process for at least partially forming a medical device, which medical device has improved physical properties.

A catheter may be used for treating chronic venous insufficiency (CVI) by remodeling a venous valve within a vein. The catheter is advanced through the vein to a position proximate the venous valve, the catheter including a hollow needle extendable out a first side wall of the catheter and an inflatable balloon located on a second, opposing, side wall of the catheter. The inflatable balloon is inflated in order to urge the catheter towards a vessel wall opposite that of the inflatable balloon. The hollow needle is advanced at least partially into the vessel wall opposite that of the inflatable balloon and a bulking agent is injected near the venous valve in order to remodel the venous valve. The bulking agent may be injected within a subintimal space within the vessel wall, or into an advential space outside of the vessel wall.
