| 20090299460 | Bifurcated Stent and Delivery System - A delivery system has a stent and a balloon The stent has a first section made of a plurality of interconnected framework members which define a plurality of potential side branches. The balloon is a dual lumen balloon that can inflate from the proximal end to the distal end with a plurality of protrusions and/or herniations. | 12-03-2009 |
| 20100030143 | FOLDING APPARATUS AND METHODS FOR BIFURCATION POST-DILATATION BALLOON - A post dilatation balloon catheter includes a balloon member having a proximal portion, a distal portion and a circumferential bulge portion. The circumferential bulge portion extends around a circumference of the balloon member and is positioned at a location between the proximal and distal portions of the balloon member. The circumferential bulge portion inflates to a maximum inflated dimension that is greater than a maximum dimension of the proximal and distal portions of the balloon member. The balloon member is arranged into a folded state by folding at least one of the distal and proximal portions of the balloon member in a separate step from folding the circumferential bulge portion. | 02-04-2010 |
| 20100069837 | Balloon Assembly and Method for Therapeutic Agent Delivery - A balloon assembly includes an elongated balloon, one or more cutting elements engaged to the balloon, and one or more therapeutic agents disposed within an opening defined by the cutting blades. The balloon assembly converts energy into heat to enhance elution of the therapeutic agent at the treatment site | 03-18-2010 |
| 20100137973 | Layered Bifurcation Stent - An implantable medical device has an outer stent with a tubular body disposed about a longitudinal axis. The outer stent includes members defining openings which are in fluid communication with a flow path. At least one opening is larger than adjacent openings when the outer stent is in an expanded state, and is positioned between the ends of the outer stent. The at least one larger opening is a side branch opening having a perimeter. The device also has an inner stent with a tubular body disposed within the outer stent and about a longitudinal axis. The inner stent has a branch portion with deployable petals positioned adjacent to the side branch opening of the outer stent. The petals are biased against the perimeter of the side branch opening such that the petals are restrained from opening outward when the outer stent is in an unexpanded state. | 06-03-2010 |
| 20100152711 | OFFSET COUPLING REGION - The invention provides a medical device delivery system comprising an offset coupling region interposed between an elongated hypotube guide member or catheter and a support segment. The medical device to be delivered is disposed about the support segment and contained and/or constrained within a containment element. The medical device may be released from the containment element by moving an actuation element from a first position to a second position. The offset coupling region allows the actuation element to exit a lumen within the guide member and to engage the containment element in the first position while traveling along a line generally coaxial with the lumen of the guide member. | 06-17-2010 |
| 20100152830 | Single Wire Stent Delivery System - A stent delivery system for deployment at a bifurcated vessel includes a catheter and a balloon. The length of the balloon is defined by a proximal balloon region and a distal balloon region. The proximal balloon region is disposed about a first longitudinal axis and the distal balloon region is disposed about a second longitudinal axis. The balloon has an unexpanded state and an expanded state, and a bend along its length. The proximal balloon region intersects the distal balloon region at the bend. In both the unexpanded state and the expanded state, at least one of the first longitudinal axis and the second longitudinal axis define an oblique angle relative to the main vessel longitudinal axis. | 06-17-2010 |
| 20110054593 | SHEATHLESS EMBOLIC PROTECTION DEVICE - An intravascular distal protection device, comprising a guidewire having a proximal end and a distal end, a filtering material disposed about the guidewire, the filtering material having a proximal edge defining a proximally facing opening when in an expanded position, a hoop wire having a proximal end and a distal end and slidably attached to the proximal edge, the hoop wire wrapped in a helical coil about the guidewire in a first contracted position and defining a hoop at the proximal end of the filtering material in the expanded position, and an actuation member attached to the hoop wire and extending at least substantially to the proximal end of the guidewire and configured to move the hoop wire between the first contracted position and the expanded position. | 03-03-2011 |

| 20110125180 | EMBOLIC PROTECTION DEVICE - The disclosure relates to an embolic filter, a support structure therefor, and methods for maintaining said filter in a compact state prior to deploying the filter. | 05-26-2011 |
| 20110137333 | EMBOLIC PROTECTION DEVICE - The disclosure describes an embolic filter and a support structure therefor. | 06-09-2011 |
| 20110137334 | Electroactively Deployed Filter Device - A medical device for capturing emboli from a blood vessel. An example medical device may include an elongated guide member. The elongated guide member may include a proximal end, a distal end, a first conductive lead, and a second conductive lead. The medical device may also include a power source connected to the first conductive lead and the second conductive lead. The medical device may also have a filter having a proximal end and a distal end, wherein the proximal end is coupled to the first and second conductive leads. The activation of the power source may transition the filter from a first compressed shape to a second expanded shape. | 06-09-2011 |
| 20110150965 | MEDICAL DEVICES HAVING ADHERENT POLYMERIC LAYERS WITH DEPTH-DEPENDENT PROPERTIES - According to one aspect of the invention, a method of forming a medical device is provided, which includes: (a) contacting a substrate with a solution that contains (i) one or more types of polymers, (ii) a solvent that contains one or more types of solvent species, and (iii) one or more optional agents, for example, one or more therapeutic agents, among others; and (b) removing the solvent from the solution, thereby forming a polymeric layer on the substrate. The composition of the solution is changed over the course of forming the polymeric layer. In another aspect of the invention, a medical device is provided, which includes a substrate and a polymeric layer over the substrate. The polymeric layer contains a copolymer that contains differing first and second monomers. The lower surface of the polymeric layer contacting the substrate has a surface concentration of the first monomer relative to the second monomer that is higher than that of the upper surface of the polymeric layer opposite the substrate. | 06-23-2011 |
