Patent number: 7070722Abstract: A process for producing a sterile foam for medical or veterinary use is provided. A physiologically acceptable formulation for application to a body as a foam contains a foamable gelling agent. The formulation is foamed and treated with a precipitant which is calcium citrate or a calcium ion. The precipitant is combined with the foamable gelling agent before or during the foaming of the gelling agent. The foam thus obtained is allowed to cure and is then immersed in a bath of the precipitant. The treated foam is dried and sterilized by exposure to gamma-irradiation or ethylene oxide.Type: GrantFiled: October 7, 1999Date of Patent: July 4, 2006Assignee: Giltech LimitedInventors: Tom Gilchrist, Eilidh Trainer

Patent number: 6447805Abstract: A composition suitable for implantation in soft tissue (for example at or around a body orifice) in order to augment the volume of soft tissue is produced. The particles, which are desirably irregularly shaped, are formed from a biodegradable phosphate glass, and may have an average particle diameter of 50 &mgr;m to 2000 &mgr;m, preferably 50 &mgr;m to 300 &mgr;m. The particles are used with a carrier medium for injection into soft tissue such as the bladder submucosa. This procedure can be applied to treat conditions such as vesicoureteric reflux. Additionally the procedure could be used cosmetically.Type: GrantFiled: February 15, 2000Date of Patent: September 10, 2002Assignee: Giltech LimitedInventor: David Michael Healy

Patent number: 6187290Abstract: There is described a foamable formulation comprising a foamable carrier and an active ingredient which may be admixed with the carrier or packaged separately and dispersed into the carrier during the foaming process. Alginate gel is a preferred foamable carrier. The foam produced from such a formulation, and a foam sheet produced by drying the foam, also form part of the invention. The formulation, foam and foam sheet are especially useful for medical applications, for example in treating burns. As apparatus to store the components of the formulation and to generate the foam is also described.Type: GrantFiled: May 7, 1997Date of Patent: February 13, 2001Assignee: Giltech LimitedInventors: Thomas Gilchrist, Eilidh Gilchrist
