Patent number: 8920404Abstract: A catheter tip designed to reduce the outflow velocity and/or directional momentum of fluid being infused by a catheter having such a tip. In one variation, a plurality of channels is provided at the distal portion of the catheter to increase the outflow cross-sectional area. In another variation, the diameter of the catheter at its distal portion where the fluid exits is increased. In yet another variation, a bullet-shaped nose is implemented which may decrease turbulence at the distal end of catheter tip. The low velocity outflow catheter tip may also be implemented on a dual lumen catheter, such as a hemodialysis catheter, to reduce recirculation rate.

Patent number: 8864712Abstract: Various sealing structures are used in a front-loading injector, for preventing leakage of spilled fluid from an external surface of a syringe into the vicinity of the drive ram. For example, a sealing gasket may be incorporated into the front face of the injector housing, for mating to the rearward circular edge of the cylindrical body of a syringe. Alternatively, sealing and locking functions may be performed by a single structure on the rearward end of the syringe. Further, leakage may be prevented by including a non-planar sealing flange on the syringe, positioned on the syringe forward of the locking structure, or by a two-piece structure, including a syringe and a separate leakage stopping washer for surrounding the syringe to halt the flow of fluid along the exterior of the syringe. (As part of this aspect, or as an independent feature, the syringe may include an annularly discontinuous flange forward of the locking structure, for providing mechanical support for the syringe against the injector.Type: GrantFiled: February 22, 2007Date of Patent: October 21, 2014Assignee: Mallinckrodt LLCInventors: Frank M.
