Abstract: An apparatus including a cannula having a dimension suitable for insertion into a blood vessel and an expandable body coupled thereto, the expandable body comprising a first expandable member and a second expandable member to isolate a length of the vessel upon expansion within the blood vessel. The expandable body having an intermediate expandable member along a working length between the first expandable member and the second expandable. A method including introducing a cannula and an expandable body coupled thereto into a blood vessel at a point coextensive with a treatment site and expanding a first expandable member and a second expandable member of the expandable body to isolate a length of the vessel adjacent the treatment site. The method further including delivering a treatment agent to a vessel region between the first expandable member and the second expandable member while inflating and deflating an intermediate expandable member.

Abstract: The invention is directed to a system for removably securing a stent which generally includes an expandable member of a catheter assembly, the expandable member having outwardly extending protrusions. An expandable stent is crimped onto the expandable member such that the protrusions extend into the gaps in the stent. The stent is secured in place on the expandable member while advancing the system through tortuous body lumen passages. The stent is implanted at the desired location in the body lumen by inflating the expandable member and thereby expanding the stent into the body lumen. The protrusions are pulled away from and out of the stent gaps by deflating the expandable member and retracting the remainder of the system.

Abstract: A catheter assembly is provided for use in delivering and implanting a stent in a body lumen, such as in a coronary artery. An elongated catheter body includes an expandable member or balloon having a folded configuration and an expanded configuration wherein a plurality of pre-formed grooves extending generally circumferentially around the balloon when the balloon is in its folded configuration. An intravascular stent is removably crimped over the balloon and is at least partially retained on the balloon by the grooves. Upon inflation of the balloon, the grooves will flatten out thereby releasing the stent and allowing the stent to expand radially outwardly into contact with the body lumen or coronary artery.

Abstract: A balloon catheter for dilating a stenotic region of a patient's body lumen such as an artery or for the implantation of an expandable stent within a patient's body lumen. The balloon of the catheter has a plurality of canted wings which are inclined at an angle of about 15° to about 75°, preferably about 30° to about 60° from a line tangent to an inner tubular member extending within the interior of the balloon.

Abstract: A catheter system for removably securing a stent which generally includes an inner tubular member and an outer tubular member with an expandable member disposed about the inner tubular member. A deformable material is disposed between the expandable member and the inner tubular member. An expandable stent is crimped onto the expandable member and is retained in place by compressing the deformable material. Used with a stent delivery system, the catheter system is inserted into a body lumen such as an artery. The stent is secured in place while advancing the system through tortuous body lumen passages. The stent is advanced to the desired location in the body lumen and implanted by inflating the expandable member and thereby expanding the stent into the body lumen. The stent is released from the system by deflating the expandable member and withdrawing the catheter system from the body.

Abstract: A binocular assembly which is held in optical alignment with a human being's eyes and without the use of a human being's hands. The binocular assembly includes a support member, a pair of optical systems positioned and mounted on the support member for magnifying items within view of the human beings eyes, an adjustment to laterally adjust and position the pair of optical systems laterally relative to one another to accommodate spacing between the human beings eyes, and a fastener for engaging the human being's head and securing the binocular assembly about the head of the human being.
