20090132025COMPOSITE STENT WITH INNER AND OUTER STENT ELEMENTS AND METHOD OF USING THE SAME - A composite stent structure includes separate and distinct stent elements or members: an outer stent element and an inner stent element removably attached to the outer stent element. The outer element may be, for example, a bioabsorbable stent typically constructed of a relatively non-resilient material such that the outer bioabsorbable stent element may not be self-expanding and subject to migration within the lumen over time. In contrast, the inner element may be, for example, a removable SEMS used to urge and maintain the outer element in position in the body lumen. The temporary inner SEMS may retain the composite structure (including the underlying inner element) in position until such time as the outer element is appropriately incorporated into the surrounding tissue or some other criteria occurs such that the removal of the SEMS is indicated. The SEMS may then be detached from the outer element and removed from the body lumen.05-21-2009
20090315208BIOABSORBABLE STENTS WITH REINFORCED FILAMENTS - According to an aspect of the present invention, a stent is provided, which contains at least one filament that has a longitudinal axis and comprises a bioabsorbable polymeric material. Polymer molecules within the bioabsorbable polymeric material are provided with a helical orientation which is aligned with respect to the longitudinal axis of the filament. The stent is at least partially bioabsorbed by a patient upon implantation or insertion of the stent into the patient.12-24-2009

20080300673RADIOPAQUE 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
20090048653ENDOPROSTHESIS HOLDER - An endoprosthesis holder includes a proximal connector structure having an outer surface. A distal connector structure has an outer surface. An intermediate connector structure is connected to the proximal and distal connector structures such that the intermediate connector structure is between the proximal and distal connector structures. The intermediate connector structure includes one or more intermediate transverse structures and one or more axial structures. The one or more intermediate transverse structures are connected to one another and to the proximal and distal connector structures by the one or more axial structures. The intermediate connector structure has an outer surface. An outward protrusion is connected to one or more of the outer surfaces of the proximal connector structure or distal connector structure or intermediate connector structure.02-19-2009
20090312834CONTINUOUS DOUBLE LAYERED STENT FOR MIGRATION RESISTANCE - The present invention relates to stent structures having improved migration resistance. In particular, the invention relates to mesh stents, such as braided or twisted stent designs, where at least a portion of the stent is folded back over itself to form a multi-layered stent device. Such multi-layered portions provide for migration resistance, among other advantages.12-17-2009
20100152612ENDOSCOPES HAVING MULTIPLE LUMENS FOR TISSUE ACQUISITION AND REMOVAL AND RELATED METHODS OF USE - Embodiments of the invention include an endoscope including multiple lumens for tissue acquisition and removal and related methods of use.06-17-2010

20120017913Tracheostomy Tube Loading Catheter - There is provided a tracheostomy tube loading catheter with a handle, mid-section, tip portion and guiding catheter portion, where the guiding catheter and tip portions are non-detachably attached to the mid-section, and where the loading catheter has a cannula therethrough.01-26-2012
20120017916Dilator With Integrated Guiding Catheter - There is provided a device for performing a tracheotomy. The tracheostomy dilator has a body, tip and guiding catheter which are non-detachably attached to each other. The dilator has a cannula sized to accommodate a guide wire. After the trachea has been dilated, the entire device may be removed, leaving only the guide wire in the stoma, and a tracheostomy tube may be inserted over the guide wire and into the trachea. This substantially reduces the number of components and steps required for a successful tracheostomy procedure.01-26-2012
