A coated medical device () including a structure () adapted for introduction into a passage or vessel of a patient. The structure is formed of preferably a non-porous base material () having a bioactive material layer () disposed thereon. The medical device is preferably an implantable stent or balloon () of which the bioactive material layer is deposited thereon. The stent can be positioned around the balloon and another layer of the bioactive material posited over the entire structure and extending beyond the ends of the positioned stent. The ends of the balloon extend beyond the ends of the stent and include the bioactive material thereon for delivering the bioactive material to the cells of a vessel wall coming in contact therewith. The balloon further includes a layer of hydrophilic material () positioned between the base and bioactive material layers of the balloon.

A medical device and a method of treating stress urinary incontinence are provided. The device includes a cannula with a plurality of apertures. A plurality of needles is disposed within a lumen of the cannula. A handle includes a housing and a shifter mechanism to translate the plurality of needles from a first position in which the needles are disposed within the lumen of the cannula, to a second position in which a distal portion of each needle extends out of the lumen through respective apertures. The handle also includes a slot including a transversal track defining a potential range of rotational motion of the shifter mechanism with respect to the housing, and a plurality of longitudinal tracks defining a potential range of translational motion of the shifter mechanism with respect to the housing. The shifter mechanism may also rotate the cannula with respect to the handle.

Multi-needle injection device

A medical device () includes a structure () adapted for introduction into a patient, the structure () being formed of a preferably non-porous base material () having a roughened or textured surface (). The structure () is conveniently configured as a vascular stent with a base material () of stainless steel, nitinol or another suitable material. The medical device () also includes a layer () of a bioactive material posited directly upon the roughened or textured surface () of the base material () of the structure (). The surface () of the base material () is roughened or textured by etching or by abrasion with sodium bicarbonate or another suitable grit. A preferred roughened or textured surface () is thought to have a mean surface roughness of about 10 &#x3bc;in. (about 250 nm) and a surface roughness range between about 1 &#x3bc;in. and about 100 &#x3bc;in. (about 25 nm and about 2.5 &#x3bc;m). The particularly preferred use of sodium bicarbonate as the abrasive to provide roughness or texture to the surface () of the base material () of the structure () is additionally advantageous in the low toxicity of the sodium bicarbonate to production workers, the ease of product and waste cleanup, and the biocompatibility of any residual sodium bicarbonate.
