Publication number: 20130110057Abstract: 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: ApplicationFiled: January 28, 2011Publication date: May 2, 2013Applicant: Atrium Medical CorporationInventors: James Croteau, Theodore Karwoski, Joanne Krawczyk, Marc Larochelle, Patrick Lee, Nicholas Want

Publication number: 20130035637Abstract: A non-polymeric or biological coating applied to a radially expandable interventional medical device in a collapsed, wrapped, or folded configuration, the coating applied within at least one fold. Properties of the coating material applied to the medical device are adjusted or varied to result in a desired combination of coverage of the surface of the medical device, drug loading, and coating thickness. The coating is sterile, and is capable of being carried by a sterile medical device to a targeted tissue location within the body following radial expansion. The therapeutic coating transfers off the medical device due in part to a biological attraction with the tissue and in part to a physical transference from the medical device to the targeted tissue location in contact with the medical device.Type: ApplicationFiled: October 12, 2012Publication date: February 7, 2013Applicant: ATRIUM MEDICAL CORPORATIONInventor: Atrium Medical Corporation

Patent number: 7947015Abstract: A non-polymeric or biological coating applied to radially expandable medical delivery device provides uniform drug distribution and permeation of the coating and any therapeutic agents mixed therewith into a targeted treatment area within the body. The delivery device is expanded using the pressure of an inflation fluid. After expanding the delivery device to a pre-determined size and shape, the inflation fluid weeps through the porous surface of the delivery device. The coating releases the delivery device and floats on the inflation fluid until bonding to the tissue due to its affinity for the tissue. Once the coating bonds or affixes to the tissue, through an absorption mechanism by the tissue cells of the coating material, the coating and any therapeutics contained therein are delivered to the tissue. The fluid can contain a therapeutic agent, or can be otherwise biocompatible and/or inert.Type: GrantFiled: May 18, 2007Date of Patent: May 24, 2011Assignee: Atrium Medical CorporationInventors: Steve A.

Patent number: 7740793Abstract: A method of making a radially expandable fluid delivery device includes providing a tube of biocompatible fluoropolymer material with a predetermined porosity based on an extrusion and expansion forming process, applying a radial expansion force to the tube expanding the tube to a predetermined diameter dimension, and removing the radial expansion force. The tube is radially inelastic while sufficiently pliable to be collapsible and inflatable from a collapsed configuration to an expanded configuration upon introduction of an inflation force, such that the expanded configuration occurs upon inflation to the predetermined diameter dimension. The fluid delivery device is constructed of a microporous, biocompatible fluoropolymer material having a microstructure that can provide a controlled, uniform, low-velocity fluid distribution through the walls of the fluid delivery device to effectively deliver fluid to the treatment site without damaging tissue proximate the walls of the device.Type: GrantFiled: February 28, 2005Date of Patent: June 22, 2010Assignee: Atrium Medical CorporationInventors: Steve A.
