Abstract: The present invention provides moldable compositions that are capable of drying and hardening if left in open air at room temperature for a period of time. Embodiments of the moldable compositions comprise water, at least one polar polymeric resin (e.g., polyvinyl alcohol), at least one thickening agent (e.g., boric acid, borate salt, or hydrate of a borate salt), at least one humectant (e.g., glycerin, propylene glycol, etc.), at least one filler (e.g., corn starch, tapioca, or arrowroot), optionally at least one releasing agent (e.g., mineral oil) and optionally at least one additive.

Abstract: An intravascular catheter capable of both rapid-exchange and over-the-wire modes of operation having a relatively long proximal shaft portion, a relatively short distal section and an intermediate shaft section, which connects the proximal shaft section and the distal shaft section. In one embodiment, the intermediate shaft section includes a guide wire port and a first guide wire lumen which extends throughout both the intermediate and distal shaft section, and a second guide wire lumen which extends throughout the entire catheter shaft. In another embodiment, the intermediate shaft section includes a y-lumen junction which allows a first guide wire lumen introduced at the intermediate shaft section and a second guide wire lumen extending from the proximal end of the catheter shaft throughout the proximal shaft section to merge and communicate with a single distal guide wire lumen which extends from the intermediate shaft section to the distal end of the catheter shaft.
