Patent number: RE38459Abstract: An injectable physiologically acceptable aqueous phase fluorocarbon emulsion, which has substantially no free fluorocarbon, has an excellent stability is prepared by a process of the invention. Typically, more than about 99.8 wt. % of the fluorocarbon remains in the size range of about 0.2 to 0.4 microns even after being stored at room temperature for one year or more in sealed containers under a non-oxidizing atmosphere. The emulsion is useful in medical applications, for example, coronary angioplasty, cancer therapy, among others.Type: GrantFiled: January 21, 1999Date of Patent: March 9, 2004Assignee: Thomas Jefferson UniversityInventors: Stuart Raynolds, Robert H.
