In one aspect of the invention, at least one radiopaque filament is arranged for permanent attachment to a hollow tubular structure. The filament is desirably arranged in a linear direction traverse to a longitudinal length of the structure, the structure having a tubular wall that defines an inner surface and an outer surface and opposing first open end and second open end. The radiopaque filament improves external imaging of the tubular structure on fluoroscope or x-ray imaging equipment. | 09-11-2008 |
| 20080300673 | RADIOPAQUE COMPOSITIONS, STENTS AND METHODS OF PREPARATION - The invention relates to an implantable radiopaque stent adapted to be disposed in a body lumen. In one aspect of the invention, a plurality of elongate filaments including one or more radiopaque filaments are arranged to form a hollow tubular structure having a tubular wall that defines an inner surface and an outer surface and opposing first open end and second open end. One of the open ends of the stent is formed by an intersection of adjacent filament ends. A radiopaque compound is applied to the intersection, the radiopaque compound comprising radiopaque material and polymeric material. The radiopaque compound and radiopaque filament provide improved external imaging of the tubular structure on imaging equipment. | 12-04-2008 |

| 20090187240 | STENT WITH ANTI-MIGRATION FEATURE - An intraluminal prosthesis includes an outer three-dimensional (3D) anti-migration structure that is attached to the outer wall of a fully covered or partially covered stent to prevent migration and still allow stent removal at a later period of time. A method of manufacturing the intraluminal prosthesis includes attaching the anti-migration structure by usage of a polymer such as polyurethane. | 07-23-2009 |
| 20100057109 | ENDOSCOPIC SUTURING DEVICE - A suturing device for use in endoscopic procedures includes a head configured to be removably coupled to an elongate medical device and an actuator coupled to the head via an elongate flexible sheath. The suturing device is configured to pass a needle and suture through a selected tissue site upon actuation of the actuator. In another embodiment, a suturing device includes a head and a retaining portion configured to receive a guide wire. The suturing device can be inserted into a patient's body using the guide wire to guide and help position the head of the suturing device. In such an embodiment, the suturing device can also include an expandable member coupled to the head and that is configured to be expanded within a body lumen of a patient to help maintain a position of the head within the body lumen. | 03-04-2010 |
| 20100331960 | ENDOPROSTHESIS AND ENDOPROSTHESIS DELIVERY SYSTEM AND METHOD - An endoprosthesis includes a structure which is self-expandable from a reduced profile to an expanded profile. The structure has one or more longitudinal portions and a transverse central plane about which the one or more longitudinal portions are symmetric. A removable sheath retains the one or more longitudinal portions in the reduced profile. A release structure is coupled to the sheath for removal thereof from the one or more longitudinal portions to provide the self-expansion thereof to the expanded profile. A method for implanting the endoprosthesis into a body of a patient includes inserting the structure which is covered by the sheath into the body of the patient such that the structure has the reduced profile. The release structure is then actuated for removing the sheath from the one or more longitudinal portions to provide the self-expansion to the expanded profile. | 12-30-2010 |
| 20110251525 | SYSTEMS AND METHODS FOR TREATING LUNG TISSUE - A system for treating lung tissue includes a tube having a distal end, an anchoring device secured to the tube, the anchoring device configured to anchor at least a portion of the tube against an esophagus, a trachea, or a bronchus; and an ablation device carried within a lumen of the tube. | 10-13-2011 |
| 20110265908 | APPARATUS AND METHOD FOR MANUFACTURING A SINGLE WIRE STENT - A mandrel for manufacturing a stent from a single wire includes a cylindrical member having a plurality of pins at a proximal end region, a plurality of pins at a distal end region, and a plurality of indentations between the proximal pins and the distal pins. These indentations form a helical pattern on the outer surface of the cylindrical member. The single wire is wrapped around every proximal pin and distal pin on the mandrel by following the indentations in the mandrel. The single wire is slid through the indentation under any crossing section of wire and over the next crossing section of wire in an under-over pattern. | 11-03-2011 |
