Embodiments of the present invention are directed to medical implants/stents, systems, and methods of treatment using such stents. Some embodiments of the invention include a self-expanding stent having a tubular first wall structure of a first diameter, where each end portion of the first wall structure is formed into a second wall structure of a second diameter larger than the first diameter. A membrane covers at least the first wall structure and the stent includes an interlaced, helicoidally wound wire forming a mesh-like structure.

An expandable venous valve having a support structure that configured to enlarge the area adjacent to the valve structure such that the flow patterns of retrograde flow are modified in a way that facilitates the flushing of the pockets at the base of the valve area to prevent stagnation of bodily fluid, which in the venous system, can lead to thrombus formation. The enlarged pocket areas can be created by forming an artificial sinus adjacent the valve structure in an unsupported section of vessel wall between two support frame section or the support frame can comprise an expanded-diameter intermediate or proximal section that forms an artificial sinus adjacent the valve structure. In another group of embodiments, the attachment pathway between opposing leaflets and the support frame and/or vessel wall comprises a proximal portion that places the leaflets in extended contact with one another and a distal portion forms a large angle with respect to the adjacent walls such that a large pocket is created at the base of the leaflets. In one embodiment, the attachment pathway extends distally along a pair of substantially parallel longitudinal attachment struts to create an extended leaflet contact area, then angles circumferentially and distally from the former along distal attachment struts to define the bottom edge of the leaflets.

A pseudo-frustoconical shaped unitary rubber end unit for an ambulatory device, such as a cane, comprising, a bottom hexagonal base and a top circular rim, wherein said base is about four times the diameter of said rim and functions to provide significantly enhanced support and stability; and a central cylindrical “socket” created by six deeply recessed side walls and a resultant six member rib-like frame that functions to optimize device's shock absorption capabilities and forward propulsion of the user. The hexagonal base may be asymmetrical or symmetrical, and the ribs may be of uniform or non-uniform dimensions. The hexagonal base and the rib-like frame act synergistically to compress and rebound under loads creating a twisting “spring assist” action that both absorbs shock and helps propel users forward. The broad base has a slightly recessed underside permitting the mobility device to be self-standing.

A catheter insertion aid for facilitating urethral insertion of a catheter comprising a hollow device having opposing flexible sides with a slit opening running between said first end and said second end of said device. The slit opening being used for removal of the catheter insertion aid from around the catheter while the catheter is still in place in the vagina. The geometry of the first end of the device being smaller than the second end of the device allowing for easy penetration by the smaller end between the labia folds. The opposing flexible sides of the device when held in a compressed position allow for easy insertion of the device between the labia folds and with the release of the compressed position, the flexible sides expand presenting the urethra for easy insertion of the catheter. A kit containing a catheter insertion aid and a catheter is also disclosed. Alternative embodiments involving a V-shaped tapered device and a device with hinged finger cups and elevations for labia spread are disclosed.
