Patent number: 10828018Abstract: The present invention relates devices capable of continuous and simultaneous expression of components of a multi-part biomedical composition with variable mixing ratios. The device has at least two syringes that contain the inter-reactive components of the multi-part biomedical composition. At least the barrel of the first syringe has a first retention compartment having a cross-sectional area dimension that is larger than the cross-sectional area of a second retention compartment. The first piston has a cross-sectional dimension that matches the inside cross-sectional dimension of the small dimensioned retention compartment, while a ring-shaped gasket is located within the large dimensioned retention compartment and has an outside cross-sectional dimension that matches an interior dimension of the large dimension retention compartment.Type: GrantFiled: August 21, 2018Date of Patent: November 10, 2020Assignee: Ethicon, Inc.Inventors: Dennis D. Jamiolkowski, An-Min Jason Sung, Leo B. Kriksunov

Publication number: 20200038215Abstract: A transient implantable device for placement within a gastrointestinal tract controls absorption of nutrients. The device includes a float that connects with a bypass tube. The device maintains its position within the gastrointestinal tract by floating on gastric fluid within the stomach. The device is further placed in a way where consumed food can pass around the device normally through the digestive tract, or food can pass through the device. The bypass tube includes a series of openings that are selectively obstructed by a film to control material entering and exiting from the bypass tube.Type: ApplicationFiled: August 1, 2018Publication date: February 6, 2020Inventor: An-Min Jason Sung

Patent number: 10226569Abstract: Exoskeletal devices or sleeves that can be used with the delivery tube of an applicator device to help dispense fluids, typically flowable biocompatible materials such as hemostatic agents, adhesives, or sealants, onto specific sites in the human body for a medical reason are disclosed. The exoskeletal devices or sleeves are rigid, pre-shaped, and snappably or slidably affixed to the delivery tube. The exoskeletal devices or sleeves do not come into contact with the flowable biocompatible fluid being dispensed, and they can be placed at any position along the delivery tube to address different application situations. Once the exoskeletal device or sleeve is in place, it can optionally be locked onto the delivery tube to prevent further sliding under stresses when pushed against tissue. Multiple exoskeletal devices or sleeves can also be used to achieve more complicated shapes for hard-to-reach anatomical sites.Type: GrantFiled: April 25, 2016Date of Patent: March 12, 2019Assignee: Ethicon, Inc.Inventors: An-Min Jason Sung, Dennis D.

Patent number: 7332227Abstract: A non-volatile lubricious coating composition is provided for use with medical devices, such as hypodermic needles, catheters, and the like. The coating composition includes a first siloxane polymer having a very low viscosity less than about 50 centistokes, a second siloxane polymer having a high viscosity greater than about 1,000 centistokes, a reactive silicone polymer which is capable of crosslinking upon exposure to radiation, such as a UV curable silicone acrylate, and a photoinitiator to accelerate cross-linking of the reactive silicone polymer. The coating composition may further include an aminofunctional siloxane polymer to promote adhesion to metal surfaces when used with needles. The coating composition provides flowability without the need for any volatile organic solvent, and is capable of curing to provide adhesion and lubricity.Type: GrantFiled: March 4, 2004Date of Patent: February 19, 2008Assignee: Becton, Dickinson and CompanyInventors: Lori Hardman, Mark Spinti, Jie Jane Ren, An-Min Jason Sung, Brian James Pelkey, Shang-Ren Wu, Lawrence Korona
