Abstract: A flexible, elongated catheter tube having distal and proximal ends and a laser cut section there between. The laser cut section makes up a majority of the catheter length and is cut in a continuous helical pattern forming interlocking teeth which can be sinusoidal, triangular, square or like shapes, preferably sinusoidal. The interior of the tube has a polymeric layer which forms the internal lumen of the catheter. The exterior of the tube has a polymer coating. A short portion of the distal end is uncut and is followed by a narrower terminal section which can be tapered for better blockage penetration. The interlocking teeth disengage and reengage in a fish-scale manner without undergoing plastic deformation of the metal tube and without substantial polymer separation from the tube exterior.

Abstract: Implantable valve for treating venous insufficiency having a self-expanding frame encased in polymer having a distal section for blood in-flow, a bulbous center section and a proximal section for blood out-flow. Polymeric leaflets have proximal ends forming an S-shaped valve outlet, or a valve outlet which spirals toward the proximal section. The valve opens and closes in response to venous blood flow and has distal portions which are integral with the inner polymer surface of the distal end of said bulbous section. The leaflets define a predominantly biomimetic sinus region with the bulbous section. Opening of the valve induces flushing of blood from the sinus region for smooth non-traumatic blood flow through said valve.

Abstract: The stent of the present invention combines a helical strut band interconnected by coil elements. This structure provides a combination of attributes that are desirable in a stent, such as, for example, substantial flexibility, stability in supporting a vessel lumen, cell size and radial strength. The structure of the stent of the present invention provides a predetermined geometric relationship between the helical strut band and interconnected coil.

Abstract: A flexible stent structure includes a plurality of axially spaced strut portions defining generally tubular axial segments of the stent and constructed to be radially expandable. A helical portion is interposed axially between two strut portions and has a plurality of helical elements connected between circumferentially spaced locations on the two strut portions. The helical elements extend helically between those locations and the length of a helical element is sufficient so that, when the stent is in a radially expanded state, it can simultaneously withstand repeated axial compression or expansion and bending.

Abstract: A self expanding flexible or balloon expandable flexible device includes a helical strut member helically wound about an axis of the stent. The helical strut member comprises a plurality of helical strut elements. A plurality of individual helical elements are helically wound about the axis of the device in the same direction of the helical strut member with the helical elements extending between and interconnecting points on subsequent windings of the helical strut member. The device can be a flow diverter, anchor, revascularization device or filter. A self expanding flexible bifurcation device can include at least one leg. The at least one leg comprising the helical strut member and the plurality of individual helical elements helically wound about the axis of the device in the same direction of the helical strut member with the helical elements extending between and interconnecting points on subsequent windings of the helical strut member.

Abstract: The present invention relates to a stent providing a high percentage of vessel coverage, preferably at least about 50% of the portion of the vessel covered by the helical elements of the stent. The stent comprises helical elements interposed between strut members in which the helical elements are connected to the strut members by linking elements. The portion of the stent having helical elements provides a high percentage of covered area for example, in an aneurysm area. The linking elements provide part of a mechanism that allows vessel coverage to be maintained as the stent is deployed from a crimped state to an expanded state allowing the helical elements to change its helix angle (the angle at which the helical elements progresses around the circumference and along the length of the stent) and thereby the pitch of the helical elements as the stent is expanded.

Abstract: A stent in the form of a thin-walled, multi-cellular tubular structure is provided. The tubular structure has a longitudinal axis and the stent includes a plurality of circumferential sets of strut members. Each set of the strut members is longitudinally displaced from each other and connected to each other by longitudinally extending links. Each set of the strut members forms a closed and cylindrical portion of the stent. Further, each set of the strut members includes a plurality of connected curve sections and diagonal sections. The sets of the strut members further include end sets of strut members located at each end of the stent and central sets of strut members located between the end sets of the strut members. The diagonal sections of the end sets of the strut members have a center portion and two ends.

Abstract: The reconstrainable stent delivery system of the present invention comprises a proximal end and distal end which include inner and outer members. A pusher is positioned at the proximal end of the inner member. A slider is located coaxially with the inner member and is positioned within the inner diameter of the stent. The slider can rotate about and move longitudinally along one of an inner shaft or tube, such as the guide wire tube, such that the proximal end of the stent can move distally as the stent deploys. A pusher can be used on the guide wire tube such that the guide wire tube, pusher, and stent move proximally relative to the outer sheath and re-constrain the stent in the outer sheath. Furthermore, the pusher and guide wire tube could move distally as the outer sheath retracts proximally for stent deployment to accommodate foreshortening.
