Abstract: A medical device is taught, including an elongate catheter body defining a proximal segment, a distal segment, and a first lumen therethrough; a tube attached to the distal segment of the catheter body, the tube defining a proximal end, a distal end, and a second lumen therethrough; wherein the proximal end of the tube is attached to the catheter body at a first joint; wherein the distal end of the tube is attached to the catheter body at a second joint; and wherein a portion of the tube extending between the first and second joints is movable with respect to the catheter body. The medical device may further comprise a deflection element attached to the distal segment of the catheter body.

Abstract: Cut-pattern designs creating a frame structure from a solid tube, which may be used as a portion of medical device, such as a catheter. The tube includes a plurality of units of cutout segments which are distributed in a band around a circumference of the tube. A tube can have multiple different zones, each having units with varying cutout segments. The cutout segments can have varying cutout surface area allowing the flexibility of the tube to be modified at any point along the tube by altering the cutout surface area with zones having greater cutout surface areas as compared to another zone are more flexible. The tube can be incorporated into a catheter.

Abstract: A crystallized bioabsorbable polymer scaffold comprises a polymer composition of poly (L-lactide-co-tri-methylene-carbonate) or poly (D-lactide-co-tri-methylene-carbonate) or poly (L-lactide-co-?-caprolactone) or poly (D-lactide-co-?-caprolactone) in the form of block copolymers of blocky copolymers, wherein the scaffold is cold-bendable.

Abstract: The present invention is an inflatable balloon which is enclosed by an expandable cover which becomes increasingly porous/permeable during expansion. The balloon is coated or enclosed with a matrix which contains a pharmaceutically active agent. During expansion of the balloon, the pharmaceutically active agent is released or extruded through the expandable cover into a body cavity such as an artery or vein. The present invention also provides for a method of treating a disease or condition by delivering the inflatable balloon to a particular body cavity.
