    • The guidewire includes a core (12) and a coil (18) in composite cooperation to enable the guidewire (10) to be used within tortuous regions of the vasculature. The core (12) has a proximal region (14) and a distal region (16). The distal region (16) includes a flattened end (32) and a tang (36) for connecting the core (12) to the coil. The coil (18) has a proximal end, a distal end and a length extending between the proximal end and the distal end. The ratio between the proximal region and the coil diameter is 1.4:1 or greater. The guidewire includes three joints for attaching the coil to the core. A distal joint (30) attaches the distal end of the coil to the flattened end (32) of the core (12). A proximal joint attaches proximal end of the coil (18) to the core (12). A medial joint attaches the length of the coil to the tang. The three joints cooperate with the 1.4:1 ratio to improve torque transmission ability of the guidewire (10) to enable the guidewire to steer through vessels with bends of over 90 degrees and with lumen diameters of less than 3 mm.

    • Devices and methods for performing intrvenous vascular procedures without cardiac bypass. The devices include various embodiments of temporary filter devices (10), temporary valves (26, 100), and prosthetic valves (80, 85, 86, 90). The temporary filter devices (10) have one or more cannulae (2) which provide access for surgical tools for effecting repair of the cardiac valves. A cannula (2) may have filters (3) of various configurations encircling the distal region of the cannula, which prevents embolism material from entering the coronary arteries, and aorta. In one embodiment, a set of valve leaflets (70, 71) extend peripherally from the filter to prevent blood flow through peripheral arteries. The temporary valve devices (26) may also have one or more cannulae (2') which guide insertion of the valve into the aorta. The valve devices (26) expand in the aorta to occupy the entire flow path of the vessel. In one embodiment, the temporary valve (26) is a disc of flexible, porous material that acts to filter blood passing therethrough. In another embodiment, the temporary valve (100) has leaflets (111) which act in concert to alternately block or allow blood flow.

    • A synthetic fiber is formed with a plurality of longitudinally-extending cavities (16, 54 and 64) which hold a medicament that is intended to be absorbed into tissue brought into contact with the fiber. The fiber can be formed by dissolving a soluble polymer component (14) of an extruded plural-component fiber (10), leaving cavities (16), that extend inward from the outer surface of the fiber in the locations of the dissolved polymer. After the fiber has been exposed to a solvent, the cavities left by the dissolved component are filled with a medicament (18). Specifically, the cavities are filled with a medicament that is mixed with a viscous carrier which solidifies within the cavities. The fibers can be used to make sutures, textile prostheses for insertion into the body, and epidermal pads and bandages. Fibers having internal cavities (64), i.e., cavities not extending to the external surface of the fiber, can be formed by extruding a single-component fiber (60) from a spinneret orifice (72) having a number of T-shaped slots extending from a central hub. A medicament is introduced into the internal cavities by soaking the fiber in a liquid containing the medicament. The internal-cavity fiber is therefore formed of polymer having some capability for liquid transport, e.g., nylon.
