Bertron, Tallahassee, Fla., John Wiley Horton, Tallahassee, Fla., and Brian J. Boothe, Raleigh, N.C., have developed a patent (7,967,779) for a "powder and liquid mixing syringe." The abstract of the patent published by the U.S. Patent and Trademark Office states: "A mixing syringe having a first sealed chamber containing a powder (powder housing) and a second sealed chamber containing a liquid (liquid housing). When the user needs to inject a patient, he or she holds the mixing syringe approximately upright and depresses a plunger. This motion causes a piercer to pierce a foil seal separating the two chambers. The liquid then drops down into the powder housing. The liquid flows through a passage in a piston located in the powder housing, where it then comes in contact with the powder itself. As the user continues pressing the plunger downward, the piercer comes to rest within the piston and seals the passage through the piston, thereby locking the piercer and piston together. The device is then ready for an injection. As the plunger is further depressed, the piston expels the powder and liquid mixture through a needle." The patent application was filed on Jan. 11, 2008 (12/008,510). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=7,967,779.PN.&OS=PN/7,967,779&RS=PN/7,967,779 Written by Anjali Jha; edited by Jaya Anand. *** Cook Medical Technologies Assigned Patent for Implantable Drainage Device with Planar Dual Curved Portion ALEXANDRIA, Va., July 4 -- Cook Medical Technologies, Indiana, has been assigned a patent (7,967,770) developed by Linsun Li, Nanjing, China, and Wenfeng Lu, Pfafftown, N.C., for an "implantable drainage device with planar dual curved portion."

The drainage devices house a drainage lumen that may extend through the curvilinear portion, which may be dimensioned to retain the drainage device within a body vessel and provide a desired fluid conductance through a tortuous portion of the drainage lumen within the curvilinear portion. The curvilinear portion may include two or more planar bends facing in opposite directions. The drainage device is preferably a biliary stent or drainage catheter constructed of thermoplastic material resilient enough to permit the bends of the curvilinear portion to straighten in response to placement of a guidewire through the drainage lumen, and to permit a portion of the tubular member to again form the plurality of bends when the guidewire is removed from the drainage lumen. In a second embodiment, methods of implanting the drainage devices within a body vessel, such as a biliary duct, are provided. For example, the drainage device may be a biliary stent implanted within the Papilla of Vater (e.g, within a biliary or pancreatic duct) without traversing the Sphincter of Oddi."
