    Abstract: A balloon catheter or stent delivery system for medical treatment of a patient has a proximal hub, a balloon, and an improved shaft design. The catheter shaft has a rapid-exchange configuration, and a tubular outer body that includes a hypotube extending from the catheter proximal end to a position at or near a proximal leg of the balloon. An inner tubular body defines a guidewire lumen extending from a distal guidewire port at the catheter distal end to a proximal port located at a position between the balloon and the hub. A distal leg of the balloon is directly or indirectly affixed to the inner body, and a proximal leg of the balloon is affixed to the distal end of the outer body. The hypotube has an aperture for accepting the inner body proximal end, and a circumferential cut pattern. The cut pattern adds flexibility, and may extend from the hypotube distal end to a position proximal of the proximal guidewire port. The cut pattern may have any desired shape, including a spiral, a helical undulating path, or an overlapping serpentine path with inflection points, for example. The hypotube has a fluid-tight covering such as a heat-shrink polymer, so the outer body supports pressure of an inflation medium. The proximal guidewire port may be positioned on or between the individual portions of the cut pattern, or at a position beyond the cut pattern.

    Abstract: The disclosure relates to a method for coating a target. The method includes providing a target and an electrospinning apparatus. The target comprises a first surface and an opposing second surface. The electrospinning apparatus comprises a mandrel, a mask including an aperture, a reservoir loaded with a solution, and an orifice fluidly coupled to the reservoir. The mandrel is located adjacent the target second surface. The orifice is located at a distance from the target first surface. The mask is located intermediate the orifice and the target first surface. The solution is electrospun through the mask aperture onto the target first surface. In one example the target is an endoluminal prosthesis.

    Abstract: An expandable stent for medical implantation is described which has a generally cylindrical structure with a central longitudinal axis. At least a portion of the generally cylindrical structure is formed from an arrangement of circumferentially curved structural members. The portion expands from a compressed state to an expanded state by a spiraling motion of each of the structural members about the central longitudinal axis. In the compressed state, each of the structural members may nest within an open region formed by segments composing the structural member, such that the portion of the generally cylindrical structure has no overlapping regions. A ratio of a circumferential length of each structural member to a spacing between adjacent structural members may be in the range of about 1.8 to about 2.3.
