Abstract: Transcatheter guidewire delivery systems, catheter assemblies and associated methods for percutaneous guidewire delivery across heart valves are disclosed herein. A catheter assembly configured in accordance herewith includes an elongated tubular component and an alignment assembly at a distal portion of the tubular component and which is adapted to be located at a target location adjacent a heart valve of a patient. In one embodiment, the alignment assembly deploys to a shape set loop configuration with a side port in an open configuration positioned to allow advancement of a guidewire to exit the catheter in an aligned path with a leaflet coaptation region of the heart valve. In another embodiment, the alignment assembly has a plurality of spaced apart side ports that a guidewire may advance therethrough and toward the heart valve. In some embodiments, a wire guide is used to align the guidewire with a selected side port.

Abstract: Catheters (e.g., 10, 10', 210) for infusion of cardiovascular fluids into blood are disclosed. The cardiovascular fluid may, for example, comprise water highly supersaturated with a gas such as oxygen. Each catheter comprises one or more capillary tubings (or capillaries) through which a cardiovascular fluid flows. The distal end of each capillary (e.g., 20, 20') is mounted (e.g., potted) preferably flush with an external surface (e.g., 48) of a catheter sidewall (e.g., 38), while the proximal end (e.g., 28) of each capillary is in fluid communication with a cardiovascular fluid flowing through the lumen of the catheter. The combination of the catheter shape and the orientation of the distal end of each capillary relative to the longitudinal axis of the catheter provides control over the mixing pattern of the cardiovascular fluid with blood flowing within a vascular space such as an aorta.

Abstract: The present disclosure relates to a PTA (percutaneous transluminal angioplasty) balloon catheter, preferably high pressure type, optionally introducible as an over the wire catheter. The catheter possess the attribute of injecting fluid to the treated site through a dedicated opening proximal to the balloon member, for introduction of fluids such as contrast enhancing material and/or medication. In some embodiments, a single lumen is used, at least in part, both for fluids transfer and dispersion ("infusion") as well as for guide wire passage. In some such embodiments, a valve mechanism is used to sustain selective operability of the lumen so that fluids will disperse mostly or solely through the proximal dispersion opening rather than the guide wire distal exit opening.
