Abstract: The objectives for the designs presented herein can be for a variably flexible and kink-resistant catheter for vascular applications. The designs benefit from good compressive and tensile stiffness. A braided wire support structure can be disposed around an inner liner and an outer layer having a plurality of outer jackets of variable durometer. A metallic reinforcing layer can be cut from a hypotube and be used as the primary structure for catheter stiffness, reducing the reliance on and number of jackets to transition stiffness changes along the length of the catheter. The metallic reinforcing layer can have one or more ribbon cut segments and one or more axial hole patterns laser cut into the hypotube to progressively evolve the stiffness from proximally regions with more column stiffness and distal regions with greater lateral flexibility. The polymer jackets can be reflowed to bond the structure together.

Abstract: An autoinjector and method of injection are described. A power spring causes rotation of a drive nut about the central axis of the autoinjector that, in turn, causes a middle screw to rotate in the same direction as the drive nut and also to move in the distal direction while pushing a center screw in the distal direction that pushes the syringe and needle. The center screw also pushes a plunger that pushes the fluid out of the syringe. After injection, a locked retract screw is freed and rotates in the same direction as the middle screw causing the syringe to retract the syringe into the housing.

Abstract: The present disclosure provides improved methods for calibrating the zero position of at least one drive member of an injector system is disclosed. Automated methods of position calibration of the drive member of a fluid injector are disclosed. These methods address sources of error in positional accuracy and fluid delivery inaccuracies, such as disposable syringe tolerance and injector wear over time. According to other embodiments of the present disclosure, methods and fluid injector systems for determining and correcting for the amount of slack in a fluid injection apparatus are described. An understanding of the calibration and the amount of slack in a fluid injection system allows a processor to correct for the slack, thereby ensuring more accurate fluid delivery to the patient and more accurate imaging processes.
