    Abstract: A bifurcation stent delivery catheter (400) includes a first branch balloon (410), a second branch balloon (450) adjacent the first branch. A centering balloon (510) is optionally disposed distal of the second branch balloon. The balloons are coupled by a coupling device to a main shaft of a catheter. The coupling device allows axial forces to be transmitted from the main shaft to the balloons while allowing the balloons to rotate axially relative to the main shaft with ease. The coupling device functions as an axial rotational joint. The coupling device can have a flexible tubular member that connects the balloons to the main shaft, the tubular member having a torsional flexibility greater than that of the main shaft. The coupling device can have a tubular wall having a cut extending circumferentially around the tubular wall and protective boot covering the cut. The coupling device can have a wound member that allows the axial rotation.

    Abstract: A catheter arrangement is arranged to permit a guide wire to be fed laterally from the region of an expandable working element. The catheter includes an elongate flexible tubular member and an inflatable structure carried by a distal portion of the flexible tubular member. The flexible tubular member has a guide wire lumen and at least one fluid supply lumen that is in fluid communication with the inflatable structure. The inflatable structure includes at least one, and preferably two, inflatable members. In this case, the inflatable members are radially spaced about the guide wire lumen such that at least one gap is formed between them. The distal end of a guide wire is then advanced through the guide lumen and out of a side opening such that it passes laterally between the inflatable members and can readily be directed into a second branch of a vessel bifurcation while the device is positioned in a first branch.

    Abstract: A method for improving the retention between the surfaces of medical devices. The method includes coating a surface of one medical device such as a stent with a coating that includes a functional group and coating a surface of another medical device such as a balloon with a coating that includes an identical or different functional group. The method further includes interacting the coated surfaces to produce a plurality of bonds between the surfaces, thereby improving retention.

    Abstract: A dual lumen guidewire support catheter for accurately crossing a chronic total occlusion in a vessel is disclosed. The dual lumen guidewire support catheter includes a first lumen portion and a second lumen portion sharing a common side and a common distal end. The first lumen portion can be a rapid exchange or over-the-wire portion, while the second lumen portion is an over the wire portion. One or both of the portions can include a discontinuity to enable removal of a guidewire following placement through or at an occlusion or lesion.

    Abstract: The present invention concerns a novel bifurcated (20) stent apparatus for use in treating lesions at or near a bifurcation point in bifurcated vessel. More particularly, a dedicated bifurcation stent apparatus is fabricated from a single tube structure for use in a bifurcated body vessel having a main lumen and a side lumen. The stent apparatus includes a first stent portion (26) comprised of a first stent pattern that is configured for radial expansion into a generally cylindrical main body. A second stent portion is integrally formed with the first stent portion, and includes a second stent pattern configured to form a first branch leg (31) and a second branch leg (32). Collectively, the first stent portion, and the branch legs form a crocodile cut shape. Each branch leg is of a cylindrical shell-shaped arc segment in a first condition, and each of the first branch leg and the second branch leg is patterned for manipulation and radial expansion, in a second condition, into a generally cylindrical first body and a generally cylindrical second body, respectively.
