摘要： Methods and apparatus are disclosed for loading a therapeutic substance or drug within a lumenal space of a hollow wire having a plurality of side openings along a length thereof that forms a hollow drug-eluting stent with a plurality of side drug delivery openings. Loading a drug within the lumenal space of the hollow stent includes a drug filling step, in which the drug is mixed with a solvent or dispersion medium. The lumenal space may be filled with the drug solution or suspension in a reverse fill process and/or a forward fill process. After the drug filling step, a solvent or dispersion medium extracting step is performed to extract the solvent or dispersion medium from within the lumenal space such that only the drug remains within the hollow stent. A stent cleaning step may be performed to an exterior surface of the hollow stent.

摘要： An aboveground sprinkling device for a spinkling system for lawns and gardens. The device has a sprinkler head at the center of its upper surface and has four sockets spaced at ninety-degree intervals around its side edge, all leading in to a central chamber immediately below the sprinkler head. An integral holding spike extends down from the bottom of the sprinkler head, preferably at the center, for holding the sprinkling device in a selected location. The spike is shaped to resist rotation. A set of plugs is provided to close the sockets that are not to be used. A hose or hoses can be secured to any one of the sockets or to several of them or to all of them to incorporate the device in a continuous sprinkler system employing a plurality of these sprinkling devices. The sockets not connected to hoses are plugged.

摘要： A method of recanalizing a chronic total occlusion (CTO) is disclosed. A catheter with a guidewire slidingly received therein is positioned proximally adjacent to the CTO. An occlusion weakening therapy effective to quickly soften and/or loosen the CTO is delivered to the CTO via the catheter. The occlusion weakening therapy includes at least one enzyme and a chelating agent which are selectively deliverable either together or separately depending on the type of material encountered by the guidewire. According to various methods, the enzyme(s) may be delivered if tissue is encountered, the chelating agent may be delivered if calcification is encountered, and both enzyme(s) and chelating agent(s) may be delivered if a fibrous cap is encountered. The distal end of the guidewire may be advanced into the CTO shortly after delivery of the occlusion weakening therapy and is manipulated through the CTO until the guidewire successfully crosses the CTO.
