Publication number: 20140102469Abstract: Methods for covalently binding a silicone polymer to hair or nails using UV light, a catalyst, a reactive solution, and compositions related thereto. The methods can include synthesizing a photo-reactive silicone and bonding the photo-reactive silicone polymer to hair, nails, or keratin. The methods can also include applying a vinyl-containing silicone polymer and a catalyst, or an aldehyde functionalized silicone polymer and reactive composition, to covalently bond the silicone polymer to hair, nails, or keratin. An advantage of covalently bonding silicone polymer to hair or nails can be that the silicone polymer add strengthens and shine to hair and nails, but are more resistant to washings with soap and shampoo than non-covalently bound silicone polymers.Type: ApplicationFiled: October 12, 2012Publication date: April 17, 2014Applicant: LIQWD, INC.Inventors: William Gunter LOUDON, Dean Vegas CHRISTAL, William Jeffrey BERTRAND

Publication number: 20130096482Abstract: A stylet having a non-round cross-sectional shape which is specifically adapted to reduce the adhesion or “stickiness” of contact between the stylet and the interior surface of the lumen of an elastomeric catheter through which it extends. The stylet may be “pre-loaded” into the catheter.Type: ApplicationFiled: October 18, 2011Publication date: April 18, 2013Applicant: MEDTRONIC XOMED, INC.Inventors: William Jeffrey Bertrand, Robert C.
