Publication number: 20230309791Abstract: A control device for use with a steerable medical device comprises a steering shaft rotatable about a longitudinal axis thereof, a first steering cam is affixed to the steering shaft to rotate in unison therewith. A second steering cam is mounted on the steering shaft and freely rotatable about the longitudinal axis of the steering shaft independent of the steering shaft. A latch assembly is operatively connected to the first steering cam and the second steering cam and operable in an inactive configuration in which the first and second steering cams are positioned to maintain first and second steering wires in an un-tensioned or reduced tension state, and further operable in an active configuration in which the first and second steering cams are positioned to maintain the first and second steering wires in a tensioned state. A rotary knob assembly is also disclosed.Type: ApplicationFiled: December 16, 2021Publication date: October 5, 2023Inventors: Yun-Siung Tony YEH, Tahua YANG, David G. MATSUURA, Belinko K.

Patent number: 10752738Abstract: An aqueous elastomer dispersion includes a dispersed phase and an aqueous phase. The dispersed phase includes an elastomer including curable aliphatic conjugated-diene elastomers, such as polyisoprene, and a minor amount of at least one additive. The aqueous phase includes water and other optional components in either a soluble state or a dispersion state. The aqueous elastomer dispersion may be prepared by dissolving an elastomer, such as rubber, and additives in a solvent mixture and then converting the resulting solution into an aqueous emulsion. The aqueous emulsion is concentrated and the solvent is stripped from it to yield a dilute latex. The dilute latex that is obtained is concentrated again. Articles made from the aqueous elastomer dispersion include medical gloves, condoms, probe covers, dental dams, finger cots, catheters and the like.Type: GrantFiled: December 20, 2018Date of Patent: August 25, 2020Assignee: ALLEGIANCE CORPORATIONInventors: Shiping Wang, Seong Fong Chen, Ida Berger, Yun-Siung Tony Yeh, Wei Cheong Wong

Publication number: 20200206392Abstract: The invention described herein relates to a therapeutic, moisturizing coating composition for elastomeric articles which is applied directly onto the skin-contacting surface of the article as part of the manufacturing process. The coating composition is thermally stable and subsequently hydrates when contacted with a moisturized skin surface to convert into a liquid “lotion” form during wearing of the article. The coating composition provides therapeutic benefits to the wearer's skin as a result of wearing the article, such as improved skin moisturization, softness of feel, improved skin elasticity and firmness, and reduced redness and irritation. The invention is particularly useful in medical gloves, including examination and surgical gloves.Type: ApplicationFiled: January 24, 2020Publication date: July 2, 2020Inventors: Shiping WANG, Yun-Siung Tony YEH, James OWENS, Wei Cheong WONG
