Patent number: 11896755Abstract: A chest drainage system including a collection device configured to receive fluid from the pleural cavity of a patient. A sensor is included to detect a pressure differential in the fluid. A display is configured to display a trend in occurrences of changes in pressure of the fluid over time in predetermined time increments based on a number of detections of pressure differentials that exceed a predetermined pressure differential during each of the predetermined time increments. The trend is correlative to the percentage of time that the patient is deemed to have an air leak in the pleural cavity in the predetermined time increments. The trend is derived from a ratio of the quantity of respiratory cycles of the patient for which the predetermined pressure differential is detected (QRCleak) in the predetermined time increments to the total quantity of respiratory cycles of the patient in respective predetermined time increments (QRCtotal).Type: GrantFiled: January 4, 2021Date of Patent: February 13, 2024Assignee: ATRIUM MEDICAL CORPORATIONInventors: James Croteau, Theodore Karwoski, Joanne Krawczyk, Marc Larochelle, Patrick Lee, Nicholas Want

Publication number: 20200254155Abstract: A method and apparatus for fluid removal from a patient includes a disposable fluid removal subassembly and a portable drive subassembly that manage controlled extraction of a fluid from a patient. The fluid removal subassembly is configured for accessing a fluid filled cavity of a patient and also coupled with a fluid flow inducer having an inflow fluid intake and an outflow fluid output. The entire fluid removal subassembly, inclusive of a connector, a fluid conduit, and the fluid flow inducer, but exclusive of the outflow fluid output and a collection bag, is fluidly sealed from an external environment, and un-vented to the external environment. The fluid removal system enables a closed-loop fluid path between the patient through to the fluid flow inducer, which is under direct control by the patient of flow rate and therefore resulting pressure in the fluid path.Type: ApplicationFiled: February 6, 2020Publication date: August 13, 2020Inventors: Theodore Karwoski, James Croteau, Jay Zimmerman

Patent number: 9314599Abstract: A pleural drainage system having an inflatable membrane and a method of using the system are disclosed. The pleural drainage system includes a pleural drainage catheter system. The pleural drainage catheter system includes an inflatable membrane and a drainage catheter integrally coupled to the inflation membrane, the drainage catheter defining a drainage lumen through which fluid is drawn from the pleural cavity, and an inflation lumen coupled for flow of inflation fluid to and from an interior of the inflatable membrane. The pleural drainage system further includes a suction system coupled to the drainage catheter and a fluid collector coupled to receive fluid from the drainage catheter. The pleural drainage system further includes an inflation system connected to deliver inflation fluid to the interior of the inflatable membrane. The pleural drainage system may be used to monitor an associated airleak in the pleural cavity of a patient.Type: GrantFiled: September 8, 2014Date of Patent: April 19, 2016Assignee: ATRIUM MEDICAL CORPORATIONInventors: Theodore Karwoski, James Croteau, Ralph Gillis, Joanne Krawczyk, Nicholas Want

Patent number: 8992493Abstract: A chest drainage system includes a collection device and a fluid pathway configured to extend from the collection device to a patient. The fluid pathway has a proximal portion configured to extend proximally toward the patient and a distal portion configured to extend distally from the patient. The chest drainage system also includes a pressure source including an accumulator configured to selectively provide sub-atmospheric pressure to the distal portion of the fluid pathway and a valve configured to selectively relieve pressure in the proximal portion of the fluid pathway. The system is configured to open the valve and to introduce the sub-atmospheric pressure from the accumulator of the pressure source when a predetermined pressure differential is detected between the proximal and distal portions of the fluid pathway.Type: GrantFiled: January 28, 2011Date of Patent: March 31, 2015Assignee: Atrium Medical CorporationInventors: James Croteau, Theodore Karwoski, Joanne Krawczyk, Marc Larochelle, Patrick Lee, Nicholas Want
