20080221670 | RADIOPAQUE POLYMERIC STENT - The invention relates to an implantable radiopaque stent adapted to be disposed in a body lumen. 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 |
20100204534 | Flexible Multi-Lumen Brachytherapy Device - A flexible, multi-lumen brachytherapy device includes a plurality of loose lumens extend through a hub towards a single point of attachment at a distal rigid section. Because the lumens are attached at only a single distal location, the lumens are free to move axially and rotatably, thereby increasing the overall flexibility of the device to thereby decrease intermittent device movement while increasing patient comfort. A novel keyed stylet can be selectively inserted to increase the rigidity of the device as needed. The ability to dynamically modify the rigidity of the brachytherapy device provides a comprehensive brachytherapy solution that satisfies concerns of the patient, the surgeon and the radiologists. | 08-12-2010 |

20110029065 | Reconstrainment Band with Reduced Removal Interference - The reconstrainment band includes a hollow generally tubular shaped band having proximal and distal ends and having an exterior surface for engaging a stent and an interior surface for engaging a delivery tube. The exterior surface has at least one fin projecting therefrom along the longitudinal axis of the band. The fin has at least one obtusely shaped surface relative to the longitudinal axis and facing one of the ends. The reconstrainment band is included in a delivery device for intraluminally positioning and deploying a radially distensible stent. Reconstrainment of a partially deployed stent is provided by the delivery device. | 02-03-2011 |
20110218610 | Dilatation and stent delivery system and related methods - The invention relates to a system for dilatation of a body passage and delivery of a stent into the body passage of a patient, and related methods of using such a system. The dilatation and stent delivery system may comprise a dilatation catheter having an expandable member on a distal end, and a stent delivery catheter configured to retain a stent and deliver the stent to a body passage. The stent delivery catheter defines a lumen sized to receive the dilatation catheter and permit movement of the dilatation catheter relative to the stent delivery catheter. | 09-08-2011 |

20140018901 | Apparatus for Loading and Delivering a Stent - A stent loading and deployment device includes an outer elongate tubular member having opposed proximal and distal ends and an inner elongate tubular member having opposed proximal and distal ends and slidably disposed within the outer tubular member. When the distal ends of the outer tubular member and the inner tubular member are axially aligned, a stent deployment region is defined there in between. The device further includes a stent loading member having opposed proximal and distal ends and slidably disposed between the outer tubular member and the inner tubular member. The distal end of the stent loading member is slidable to a distal position past the distal end of the outer tubular member for receiving a stent and is further slidable toward the proximal end of the outer tubular member to a location past the stent deployment region for disengagement of a stent from the stent loading member. | 01-16-2014 |
