Patent number: 8853184Abstract: Described herein are polysaccharide gel formulations including at least one inhibitor of polysaccharide degradation and methods of making the same. The methods described herein involve the steps of providing at least one polysaccharide and incorporating at least one inhibitor of degradation into the polysaccharide. In some embodiments, the incorporating step comprises 1) mixing the at least one inhibitor with the at least one polysaccharide at a highly hydrated state thereby encapsulating the at least one inhibitor in a polysaccharide network, and 2) dehydrating the polysaccharide network thereby controlling release kinetics or final swell ratio. In another embodiment, the incorporating step comprises 1) encapsulating at least one inhibitor into a biocompatible or biodegradable vessel and 2) combining the polysaccharide and the vessel into a gel formulation. The polysaccharide gel formulations described herein can be used for a variety of cosmetic applications.Type: GrantFiled: March 27, 2013Date of Patent: October 7, 2014Assignee: Allergan, Inc.Inventors: Dimitrios Stroumpoulis, Christopher S.

Publication number: 20140288363Abstract: An implantable device comprises a reservoir that contains a fluid for filling an inflatable portion of a gastric band. A device is coupled to the reservoir and includes stored potential energy having a first state and a second state. The first state represents a higher level of potential energy and the second state represents a lower level of potential energy. The implantable device further comprises a filling valve coupled between the reservoir and the gastric band, and the filling valve is configured to be opened in response to a first telemetric signal. The stored potential energy decreases from the first state to the second state when the filling valve is open, and a filling amount of the fluid moves from the reservoir to the gastric band when the stored potential energy decreases from the first state to the second state.Type: ApplicationFiled: March 25, 2014Publication date: September 25, 2014Applicant: APOLLO ENDOSURGERY, INC.Inventor: Dimitrios Stroumpoulis
