Patent number: 10465094Abstract: A silicone coating process that improves the durability of silicone coatings on the surfaces of surgical needles and other medical devices. The silicone coated surgical needles or medical devices produced by this process have both superior lubricity and durability for ease of repeated and successive passes through tissue. The coating compositions used in the novel process contain an excess amount of polymethylhydrosiloxane cross-linker. After curing, the process utilizes gamma radiation to treat the lubricious coatings. The coatings have improved durability and performance. The penetration performance of needles coated by this novel method remains constant and flat over at least one hundred repeat passes through tissue or tissue simulation media. This provides a consistent or flat tactile response from the needles to the hand of the surgeon during a lengthy closure process, rather than an unpredictably increasing force profile.Type: GrantFiled: December 8, 2016Date of Patent: November 5, 2019Assignee: Ethicon, Inc.Inventor: Duan Li Ou

Patent number: 10442564Abstract: The printing device, first, as shown in FIG. 2A, forms white layers (90) by a first white inkjet head on the surface of the can body (10). Next, as shown in FIG. 2B, irradiation of ultraviolet rays by a first irradiation lamp (261) is performed and the white layers (90) are cured. Then, the can body (10) is moved to a second white inkjet head and, as shown in FIG. 2C, more white ink is loaded on some of the white layers (90) formed by the first white inkjet head. As a result, the thickness of some of the white layers (90) is increased. Next, the can body (10) passes successively under multiple color inkjet heads. As a result, color ink layers (91) are formed on the surface of the can body (10) and the white layers (90), as shown in FIG. 2D.Type: GrantFiled: September 8, 2014Date of Patent: October 15, 2019Assignee: SHOWA ALUMINUM CAN CORPORATIONInventors: Shinichi Ojima, Asumi Suwa, Kazunori Ikeda, Tetsuo Kashiwazaki
