Publication number: 20130072869Abstract: A timed-release drug delivery assembly includes an expandable structure and drug microparticles. The expandable structure is defined by host material that causes expansion of the expandable structure. The expandable structure has a non-expanded state prior to exposure to a gastric environment during which a size of the expandable structure enables entry of the expandable structure into a stomach of a patient, and an expanded state after exposure to the gastric environment during which the size and shape of the expandable structure prevents exit of the expandable structure from the stomach. The drug microparticles are held at least in part by the host material to enable release of the drug microparticles into the gastric environment over a predefined period of time. The expandable structure may include, in the expanded state, a substantially hollow framework to avoid blocking a pyloric valve of the stomach.Type: ApplicationFiled: August 30, 2012Publication date: March 21, 2013Applicant: THE JOHNS HOPKINS UNIVERSITYInventors: Protagoras N. Cutchis, Steven M. Babin

Patent number: 7080646Abstract: The portable ventilators of the present invention provide a hands-free ventilatory support device in critical care, emergency and resource limited environments. The portable ventilators utilize ambient air and include a two dual head compressor system to provide a consistent air supply to the patient. The ventilator device is battery operated and is capable of providing up to 60 minutes of care.Type: GrantFiled: August 26, 2002Date of Patent: July 25, 2006Assignee: Sekos, Inc.Inventors: William P. Wiesmann, Protagoras N. Cutchis, Loland Alex Pranger

Patent number: 7032589Abstract: A portable ventilator for providing an air-recipient with compulsory respiration is provided with an outlet manifold and a single-expansion-chamber muffler configured so that airflow through an inhale outlet port of the muffler is pulse-free and a transmission loss, defined as the ratio of sound power generated by the at least one compressor and incident on the muffler to the sound power transmitted by the muffler, is sufficient to deaden the sound power of the compressor.Type: GrantFiled: January 23, 2003Date of Patent: April 25, 2006Assignee: The Johns Hopkins UniversityInventors: Charles W. Kerechanin, II, Dexter G. Smith, Jennifer A. Nix, Protagoras N. Cutchis

Patent number: 6848444Abstract: An emergency life support system including a patient ventilator for mechanical breathing assistance; a capnograph to monitor CO2 for ventilation effectiveness; a pulse oximeter for measuring blood stream oxygen saturation; a carbon dioxide sensor; an electrocardiograph (ECG) to monitor cardiac performance; an infusion pump; and alarms and a data recorder. The preferred embodiment uses an oxygen generator to deliver oxygen, to generate electric power to run the ventilation system, and to warm IV fluids and resuscitated air. The generator has electronically controlled valves and a modified valve system that offers the ability to select the oxygen concentration in the air delivered to the patient.Type: GrantFiled: July 31, 2001Date of Patent: February 1, 2005Assignee: The Johns Hopkins UniversityInventors: Dexter G. Smith, Protagoras N. Cutchis, William P. Wiesmann, Loland A. Pranger

Patent number: 6647983Abstract: A low-pressure valve enabling precise control of a fluid flow rate through the valve during cyclical operation of the valve. The valve is useful for controlling air delivery to a patient as part of a portable ventilator. The valve comprises a housing having an inlet 16 and two outlets 18 and 20. A wiper plate 22 and an orifice plate 24 are disposed inside of the housing. Transverse movement of the wiper plate 22 relative to the orifice plate 24, powered for example by a servomotor 34, simultaneously and alternatively covers and uncovers various openings 26 in the orifice plate 24. The total flow through the valve is thereby divided between the two outlets 78 and 20.Type: GrantFiled: March 6, 2001Date of Patent: November 18, 2003Assignee: The Johns Hopkins UniversityInventors: Dexter G. Smith, Michael P. Boyle, Protagoras N. Cutchis, William R. Allmon

Patent number: 5969504Abstract: An automatic battery power switch circuit which switches from n to n+m cells, where n and m are integers, in a battery. The circuit delivers a relatively constant voltage over a wide range of load current conditions. One embodiment switches based on load current. Another embodiment switches based on the output voltage of the circuit. The circuit provides a high speed automatic switch used in devices that require at least two power states, that can function as a voltage regulator, and that can significantly prolong functional battery life.Type: GrantFiled: March 6, 1998Date of Patent: October 19, 1999Assignee: The Johns Hopkins UniversityInventor: Protagoras N.
