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

Patent number: 10869902Abstract: A cured non-polymeric gel including a plurality of non-polymeric cross-links. The non-polymeric cross-links result from curing an oil or oil composition at selected curing conditions to achieve a desired amount of cross-linking to form the non-polymeric gel. The desired amount of cross-linking is selected based on a desired rate of degradation of the gel after the gel is implanted. The oil or oil composition comprises one or more of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), or alpha-linolenic acid (ALA).Type: GrantFiled: December 14, 2017Date of Patent: December 22, 2020Assignee: ATRIUM MEDICAL CORPORATIONInventors: Roger Labrecque, Philip McNamara, Joseph Ferraro, Lisa Rogers, Paul Martakos, Theodore Karwoski, Steve A.

Patent number: 10792312Abstract: A barrier layer and corresponding method of making provide anti-inflammatory, non-inflammatory, and anti-adhesion functionality for a medical device implantable in a patient. The barrier layer can be combined with a medical device structure to provide anti-adhesion characteristics, in addition to improved healing, non-inflammatory, and anti-inflammatory response. The barrier layer is generally formed of a naturally occurring oil, or an oil composition formed in part of a naturally occurring oil, that is at least partially cured forming a cross-linked gel. In addition, the oil composition can include a therapeutic agent component, such as a drug or other bioactive agent.Type: GrantFiled: September 20, 2017Date of Patent: October 6, 2020Assignee: ATRIUM MEDICAL CORPORATIONInventors: Joseph Ferraro, Lisa Rogers, Paul Martakos, Theodore Karwoski, Steve Herweck, Keith Faucher, Phillip McNamara

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: 10603153Abstract: A hernia patch supporting tissue in-growth conforms to a tissue wall upon surgical installation and fixation within a patient. The hernia patch can include a base and positioning straps. The base is formed of two layers that are affixed to each other around the perimeter of the patch, for example by stitching. A stabilizing washer is provided between the two layers, and the stitch is provided peripherally around the stabilizing washer, keeping the washer free-floating between the layers. The base, positioning straps, and stabilizing washer are formed of a structure that does not separate the layers of the implant or form a space in the form of a pocket, and promotes more uniform and confluent tissue incorporation or in-growth after implantation. The hernia patch may further include a hydrolysable bioabsorbable cross-linked coating of a fatty acid based material, such as an omega-3 fatty acid based material.Type: GrantFiled: November 23, 2015Date of Patent: March 31, 2020Assignee: ATRIUM MEDICAL CORPORATIONInventors: Anthony R Horton, Paul Martakos, Steve A Herweck, Theodore Karwoski, Joseph F Ferraro
