Publication number: 20140148687Abstract: Method and medical devices for generating and stabilizing micro or nano bubbles, and systems and methods for therapeutic applications using the bubbles, is provided. Two novel bubble generating means are provided: in-line capillary tubes and mix chambers flow focusing, and cross flow bubble generation with optimized bubble detachment means. A method and medical device to stabilize bubble sizes and improve bubble size homogeneity through rectified diffusion is disclosed. A method and system to facilitate acoustic activation of therapeutic agents using ultrasound energy is provided.Type: ApplicationFiled: February 4, 2014Publication date: May 29, 2014Applicant: Artenga Inc.Inventors: James A.

Patent number: 8679051Abstract: Method and medical devices for generating and stabilizing micro- or nano-bubbles, and systems and methods for therapeutic applications using the bubbles, are provided. The micro-bubbles may be used to enhance therapeutic benefits such as ultrasound-guided precision drug delivery and real-time verification, acoustic activation of large tumor masses, enhanced acoustic activation through longer retention of therapeutic agents at the point of interest, enhancement of high intensity focused ultrasound treatments, light activation of photodynamic drugs at a depth within a patient using extracorporeal light sources, probes, or sonoluminescence, and initiation of time reversal acoustics focused ultrasound to permit highly localized treatment.Type: GrantFiled: January 7, 2010Date of Patent: March 25, 2014Assignee: Artenga IncInventors: James A Keenan, Junjie Gu, Philippe Joel Genereux, Adrian T Bienkinsop, David H Gerwing, Sebastien Roy Fournier, Sarah Katherine Dobbin

Patent number: 8257338Abstract: Medical apparatus and processes controllably generate medically useful micro or nano bubbles of medically desirable and controllably selectable size, size distribution, homogeneity and concentration (and/or other key bubble parameters) for patient infusion, and/or which may incorporate therapeutic or other agents for patient infusion and/or may be combined with therapeutic or other agents prior to infusion into patients. The bubble generation apparatus and processes controllably permit the adjustment and selection of key bubble parameters through bubble generation actuation and orientation techniques and through selection of bubble fluid compositions in order to facilitate medical research and/or to optimize treatment for imaging, therapy, sonoporation, inertial and non-inertial cavitation, and acoustic activation, among other medical uses. Disposable cartridges containing such bubbles are provided and may include means for patient infusion.Type: GrantFiled: May 5, 2008Date of Patent: September 4, 2012Assignee: Artenga, Inc.Inventors: James A. Keenan, Adrian Blenkinsop, Phillipe Genereux
