| 20090012596 | Stent with Bioabsorbable Membrane - In at least one embodiment, the invention is directed to a stent having a tubular wall where at least a portion of the tubular wall comprises a bioabsorbable membrane. In the portion of the tubular wall containing the bioabsorbable membrane, the members (e.g. struts and connectors) of the stent are embedded in the bioabsorbable membrane. In at least one embodiment, the stent is also configured to elute a therapeutic agent. | 01-08-2009 |
| 20090012599 | Biodegradable Connectors - An expandable bifurcated stent is formed of a main body and a first branch. The body wall is made up of interconnected stent members that define a plurality of cells, at least one of which is a side opening. The first branch body extends from the body wall from at least two regions adjacent the side opening. At least one stent member adjacent the perimeter is bioabsorbable. | 01-08-2009 |
| 20090287289 | BIFURCATION STENT CRIMPING SYSTEMS AND METHODS - A stent crimping system and method for use in preparing a bifurcation catheter assembly for use in a patient. The catheter assembly includes main and side catheter branches and a stent. The stent includes a side branch aperture through which the side catheter branch extends. The stent is crimped onto the main and side catheter branches with a crimping mechanism in two crimping steps. In the first crimping step, only a distal end portion of the stent is crimped while the side catheter branch remains extending through the side branch opening of the stent and remains positioned outside of the crimping mechanism. In a second crimping step, the entire stent is crimped with the crimping mechanism. | 11-19-2009 |
| 20090299454 | Staggered Two Balloon Bifurcation Catheter Assembly and Methods - A catheter assembly and related methods directed to stent delivery systems that include a stent and a catheter assembly having first and second balloons. The stent includes a side branch aperture and expandable structure defining the side branch aperture. The expandable structure is configured to move into a radial outward orientation relative to a sidewall of the stent. The portions of the first and second balloons are positioned within the stent in a generally coaxial arrangement with the first balloon extending distally from the distal open end of the stent and the second balloon extending proximally from the proximal open end of the stent. The expandable structure of the stent is moved towards the radial outward orientation by advancing the second balloon at least partially distally through the side branch aperture. In some arrangements, the second balloon is at least partially inflated when advanced through the side branch aperture. | 12-03-2009 |
| 20090312702 | BIFURCATION CATHETER ASSEMBLY WITH DISTALLY MOUNTED SIDE BALLOON AND METHODS - A catheter assembly and related methods directed to a main balloon and a side balloon, wherein the side balloon is coupled in fluid communication with the main balloon at a location distal of the side balloon. In one example, a side inflation member couples the side balloon in fluid communication to the main balloon at a distal end portion of the main balloon. A side catheter branch of the catheter assembly, which defines a side guidewire lumen, can be operatively mounted to the side balloon at a side balloon connection point to help maintain alignment of the side catheter branch relative to the side balloon. | 12-17-2009 |
| 20090326643 | BALLOON FOLDING APPARATUS AND METHOD - A catheter assembly and related methods for preparing and assembling catheter assemblies. The catheter assembly includes main and side balloons. The main balloon includes side portions that are folded in opposite directions toward a bottom surface of the main balloon to place the main balloon in a folded state. The side balloon is typically positioned along a top surface of the main balloon. The folded balloons can be retained in a folded state with various retaining structures during further preparation and assembling of the catheter assembly. | 12-31-2009 |
| 20100030140 | LOCATING SIDE CATHETER BRANCH RELATIVE TO INFLATION PORTION - A side catheter branch of a catheter assembly is oriented with respect to the main or side balloons of a catheter assembly. In some examples, the orientation is accomplished by connecting the side catheter branch to the main and/or side balloons or waste portions thereof. In other examples, the side catheter branch is positioned within the folds of the main or side balloons during assembly of the catheter assembly. In this manner, the side catheter branch remains in a known orientation with respect to the main and/or side balloons prior to and/or after deployment. | 02-04-2010 |
| 20100030315 | BIFURCATION CATHETER ASSEMBLY AND METHODS - A catheter assembly includes a main catheter branch and a side catheter branch. The main catheter branch includes a main balloon, a side balloon and a side inflation member. The side inflation member intersects the side balloon at a location on the side balloon that is offset laterally from a central line passing from a distal most point on the side balloon to a proximal most point on the side balloon. The side balloon is configured to extend radially outward relative to the main balloon when the side balloon is inflated. The side catheter branch can be centrally aligned with the side balloon central line and be positioned laterally adjacent to the side inflation lumen. | 02-04-2010 |
| 20100030317 | BIFURCATION CATHETER ASSEMBLY SIDE CATHETER BRANCH CONSTRUCTION AND METHODS - A catheter assembly includes a main catheter branch and a side catheter branch. The main catheter branch includes a main balloon and a side balloon. The side catheter branch includes a transparent portion along at least a portion of a length of the side catheter branch. The transparent portion of the side catheter branch permits viewing of the side balloon through the transparent portion for alignment of the side balloon relative to the side catheter branch. The catheter assembly can further include a stent, wherein the stent includes a lateral branch opening. The transparent portion of the side catheter branch can also provide viewing of the side balloon through the side catheter branch to help align the side balloon with the lateral branch opening. | 02-04-2010 |
| 20100069882 | MEDICAL DEVICE WITH PREFERENTIAL BENDING - Medical devices such as catheters may provide advantages in flexibility, strength and other desired properties. Some medical devices may include a hypotube that has a plurality of slots disposed therein. The hypotube or another portion of the medical device may cause or permit the medical device to exhibit preferential bending in a single direction. | 03-18-2010 |
| 20100070023 | BIODEGRADABLE CONNECTORS - An expandable bifurcated stent is formed of a main body and a first branch. The body wall is made up of interconnected stent members that define a plurality of cells, at least one of which is a side opening. The first branch body extends from the body wall from at least two regions adjacent the side opening. At least one stent member adjacent the perimeter is bioabsorbable. | 03-18-2010 |
| 20100312322 | Medical Balloon Incorporating Electroactive Polymer and Methods of Making and Using the Same - An expandable medical balloon having at least one static state, at least one expanded state, and at least one deflated state, the expandable medical balloon including at least one active region, the at least one active region including electroactive polymer. | 12-09-2010 |
