Abstract: Bifurcated delivery assemblies provide bilateral access to first and second branch lumens extending from a main body space or lumen in a patient. One or more interventional devices are combined with the delivery assemblies for delivery s into one or both of the branch lumens. Bilateral renal stenting or embolic protection procedures are performed using the combination delivery/interventional device assemblies. Fluids may also be injected or aspirated from the assemblies. A bifurcated catheter has a first fluid port located on one bifurcation branch, a second fluid port located on a second branch of the bifurcation, and a third fluid port positioned so as to be located within a vena cava when the first and second ports are positioned bilaterally within first and second renal veins.

Abstract: A locking clamp is provided that is used for securing at least one tube. The locking clamp has a first and second end axially opposed end pieces and a plurality of locking members extending between the first and second end pieces. Living hinges connect the first and second end pieces to the locking members and allow selective movement of the locking members between an unlocked position and a locked position. In the locked position, the locking members can extend in overlying partially coextensive relation to each other, and the one set of locking members can be defined in a substantially axially opposed, coplanar parallel relationship to the second set of locking members. The clamp may be used during high pressure applications to secure one tube in relationship to another tube.

Abstract: The present systems combines a drug delivery catheter and a dilator apparatus for use in lysing of clots wherein an internal dilator has a central lumen and an outer catheter is arranged coaxially about said internal dilator. An annular space for fluid passage is sealingly formed between an outer wall of the internal dilator and an inner wall of the outer infusion catheter. Apertures are located in the outer wall of the outer catheter for distributing fluid from the annular space. The internal dilator has a tip element and the outer catheter has an end opening so that together the end opening is occluded by the tip element which protrudes beyond the outer catheter when the outer catheter is arranged coaxially about the internal dilator and additionally the internal dilator is removable from the outer catheter to enable the introduction of a larger guide wire for further medical procedures.
