Title: Electroactive polymer-based actuation mechanism for linear surgical stapler
Inventor: SWAYZE JEFFREY S
IPC: A61B17/072
Filed: 2006-09-28
Abstract: Methods and devices are provided for actuating and/or articulating a surgical stapler. In one embodiment, a surgical stapler is provided having a stapling mechanism or end effector that is movably coupled to a distal end of an elongate shaft. An electrically expandable and contractible actuator, such as an electroactive polymer actuator, can be used to pivotally or angularly adjust a position of the stapling mechanism relative to the elongate shaft by delivering energy to the electroactive polymer actuator. In another embodiment, an electroactive polymer actuator can be used to actuate the staple applying assembly, thereby driving one or more staples, and preferably at least two linear rows of staples, into tissue. The actuator can alternatively or additionally drive a blade distally to cut tissue being stapled.

Title: Parfried frozen french fry having high solids content
Inventor: HAMANN MICHAEL L
IPC: A23L19/18
Filed: 2005-04-21
Abstract: Improved parfried and frozen French fry potao strips and a related production process are provided, wherein the French fry strips exhibit a relatively high solids content and a correspondingly low moisture content in the parfried frozen state. Elongated cut French fry strips are initially blanched and then subjected to an extended dry step for removing moisture therefrom. Following the dry step, the potato strips are partially rehydrated by contacting the external surfaces thereof with a moisture-laden agent such as a batter coating, followed by a single parfry step and prompt freezing. The parfried frozen potato strips exhibit a high solids content on the order of about 33-42%. These high solids strips can be finish prepared by finish frying, or by alternative methods such as heating in a convection oven, with the finish prepared potato strips exhibiting a desirable set of taste, texture and color attributes.

Title: Nut seal assembly for coaxial connector
Inventor: MONTENA NOAH
IPC: H01R24/38
Filed: 2005-04-28
Abstract: An integrated seal assembly (60) and a connector (10) incorporating the seal assembly for connecting a coaxial cable (12) to an externally threaded port (100). The seal assembly includes a bellows-type seal having an elastically deformable tubular body and a plurality of sealing surface, and an integral joint-section (65) intermediate an exterior end (58) and a posterior end (59) that assists in the axial deformation of the seal in response to axially-directed force. One of the sealing surfaces is made to engage a corresponding surface of an internally threaded nut (40). The nut and attached seal form an integral seal assembly. A coaxial cable connector (10) includes a connector body (20). One end of the body attaches a coaxial cable (12), the seal assembly being rotatably attached to the other end. The connector is engageable with an externally threaded port via the internally threaded nut component of the connector. The anterior end of the seal fits over the port and a sealing surface of the seal is capable of sealing axially against a shoulder of the port while the seal body covers the otherwise exposed externally threaded port. Upon tightening of the nut on the port, the seal deflects in the axial direction to accommodates a variety of distances between the connector and the shoulder of the port. Additionally, the seal is capable of expanding to allow a second sealing surface to contact and seal against a variety of smooth outside diameters of the port. The versatility of the seal allows an operator to use one connector on a wide variety of externally threaded ports without the risk of a faulty seal at the connection or a poor connection due to an improper seal.

Abstract: Formulations have been developed to treat or reduce the spread of respiratory infections, especially chronic or drug resistant infections, particularly tuberculosis (TB), severe acute respiratory syndrome (SARS), meningococcal meningitis, Respiratory syncytial virus (RSV), influenza, and small pox.  Formulations include a drug or vaccine in the form of a microparticle, nanoparticle, or aggregate of nanoparticles, and, optionally, a carrier, which can be delivered by inhalation. Giving the drugs via an inhaler sidesteps the problems associated with oral or injectable drugs by bypassing the stomach and liver, and delivering the medication directly into the lungs. In one embodiment, the particle containing the agent is a large porous aerosol particle (LPPs). In another embodiment, the particles are nanoparticles, which can be administered as porous nanoparticle aggregates with micron diameters that disperse into nanoparticles following administration. Optionally, the nanoparticles are coated, such as with a surfactant or protein coating. The formulation may be administered as a powder or administered as a solution or via an enteral or non-pulmonary parenteral route of administration. The formulation is preferably administered as a pulmonary formulation. In the preferred embodiment for treatment of TB, the vaccine is a BCG vaccine that is stable at room temperature, or is an antibiotic effective against TB, such as capreomycin or PA-824, loaded at a very high percentage into the microparticles or nanoparticles. In one embodiment, a patient is treated with formulations delivering both antibiotic and vaccine.
