A patterned coating on a prosthesis, for example a stent, and a method for forming the coating are disclosed. Additionally, an apparatus for forming the patterned coating is disclosed.

A flexible, sectioned plastic arm for a showerhead comprises a series of interconnected ball-and-socket (B&S) sections (10) with a proximal (shower pipe) end piece (12) and a distal (showerhead) end piece (14). Each B&S section has a proximal (cup or socket) end (10S) and a distal (ball) end (10B). The proximal end piece has a proximal end with female threads which can be screwed onto a shower pipe and a ball-shaped distal end for snapping into the socket of the most proximal section of the shower arm. The distal end piece has a proximal end with a socket for snapping onto the most distal end section of the shower arm and a distal end with male threads (12T) which can be screwed onto the showerhead. The arm has a through hole containing a series or chain of cylindrical brass or other metal sections, tubes, or sleeves (16). These prevent the arm from being bent too far, thereby to keep the B&S from separating. The two end tubes abut a pair of respective resilient spacers (18) or springs (18S), which in turn abut shoulders in the end pieces to keep the series of tubes in place. Inside the series of tubes is a flexible plastic tube (20) for carrying the water without leakage. A T-shaped end fitting (20T) is attached to each end of the plastic tube. These end fittings hold the tube in the arm. The top arm of the T of the distal end fitting sits in the bottom of the female threaded end of the proximal end piece. The top arm of the T of the distal end fitting sits on the very end of the male threaded end of the distal end piece.

A holder device may be attached to a water outlet tube which is extended from a wall, without drilling holes in the wall, and includes a housing having an inlet attached to the water outlet tube, and two or more outlet ports for attaching a shower head and a sprayer nozzle simultaneously. The housing includes an attaching device for attaching the sprayer nozzle to the housing. A controlling device may control the water to flow out through the outlet ports. The housing includes a casing having a chamber to receive a valve stem of the controlling device. The valve stem includes a passage for communicating the inlet with either or both of the outlet ports of the housing.

A flexible garden hose having an inner tube member made from elastic material and an outer tube member made from a non-elastic material. The inner tube member is secured to the outer tube member only at an inlet coupler and an outlet coupler. The inlet coupler is constructed to secure to a water supply provided from a conventional household water spigot. The outlet coupler is coupled to a flow restrictor allowing the inner tube member to equalize in pressure with pressurized water received from the water supply. Pressurized water expands the elongated inner tube member longitudinally along a length of the inner tube member and laterally across a width of the inner tube member thereby substantially increasing the length of the hose to an expanded condition wherein the hose contracts to a substantially decreased length when there is a decrease in pressurized water.

A hose which automatically expands longitudinally and automatically expands laterally upon the application of a fluid pressure is disclosed. The hose can automatically expand longitudinally up to six times its unexpanded or contracted length. Upon release of the fluid pressure within the hose, the hose will automatically contract to a contracted condition. The hose includes an inner tube made from an elastic material and an outer tube made from a non-elastic material. The inner tube is positioned concentrically within the outer tube in both a contracted condition and an expanded condition. The outer tube is secured to the inner tube only at a first end of the inner and outer tubes and at a second end of the inner and outer tubes. The outer tube moves laterally and longitudinally with respect to the inner tube when the tubes are transitioning between a contracted condition and an expanded condition.
