Patent number: 9155864Abstract: A system for controlling fluid flow in a catheter assembly is disclosed. The system comprises an intravenous catheter assembly with a catheter adapter. The catheter adapter comprises an inner lumen with a septum disposed within a portion of the inner lumen. The septum has a barrier capable of being deformed from a relaxed position to a biased position. The barrier further comprises a slit having a closed configuration and an opened configuration. The slit is in the closed configuration when the barrier is in the relaxed position and in the opened configuration when the barrier is in the biased position. The barrier is configured to be mechanically deformed from the relaxed position to the biased position by a septum actuator that advances against a proximal surface of the barrier without traversing the barrier.Type: GrantFiled: October 4, 2012Date of Patent: October 13, 2015Assignee: Becton, Dickinson and CompanyInventors: Marty L. Stout, Austin Jason McKinnon

Patent number: 9114241Abstract: A flushable catheter assembly having features to enable selective activation of fluid flow through the catheter assembly is disclosed herein. A septum is placed within the catheter adapter of the catheter assembly and includes a pathway that is closed prior to being biased open via a septum activator also positioned within the catheter adapter. A plurality of air vent channels is interposed between the septum and the inner surface of the catheter adapter to permit “flashback” of blood during insertion of the catheter into a patient. The septum activator is advanced through the pathway of the septum as a coupler is attached to a proximal opening of the catheter adapter.Type: GrantFiled: October 28, 2013Date of Patent: August 25, 2015Assignee: Becton, Dickinson and CompanyInventors: Marty L. Stout, Weston F. Harding, S. Ray Isaacson, Jonathan Karl Burkholz, Austin Jason McKinnon

Patent number: 9089671Abstract: Systems and methods for sealing and venting a septum of an intravenous catheter device. Implementations of the present invention include a compact, molded septum that is retained within an inner lumen of a catheter adapter such that slowed or stopped flow of air and/or a fluid is permitted to pass between the compact septum and an inner wall surface of the catheter adapter via one or more fluid pathways. In some instances, a snap ring is provided to secure the position of the compact septum within the catheter adapter, a fluid pathway being provided through the snap ring.Type: GrantFiled: October 3, 2012Date of Patent: July 28, 2015Assignee: Becton, Dickinson and CompanyInventors: Marty L.

Patent number: 8679063Abstract: A system for controlling fluid flow in a catheter assembly is disclosed herein. An intravenous catheter assembly has a catheter adapter and a needle hub, and the catheter adapter has an inner lumen. A septum is disposed within a portion of the inner lumen, and a slit is formed through the septum. A Parylene coating is disposed within the slit of the septum, the Parylene coating has a thickness of between approximately 0.00005 to 0.0005 millimeters. An introducer needle has a first end coupled to the needle hub and the second end extending through the inner lumen of the catheter adapter. A middle portion of the introducer needle is positioned within a portion of the septum.Type: GrantFiled: March 7, 2011Date of Patent: March 25, 2014Assignee: Becton, Dickinson and CompanyInventors: Marty L.

Publication number: 20140058336Abstract: A medical device is presented, which includes a fluid pathway and a septum slidably housed within the fluid pathway. The septum can be opened by a septum actuator disposed in a fixed position within the fluid pathway. In some examples, both the septum actuator and the septum have at least one surface exposed to the fluid pathway. An anti-pathogenic material can be applied to these surfaces.Type: ApplicationFiled: August 22, 2012Publication date: February 27, 2014Applicant: BECTON, DICKINSON AND COMPANYInventors: Jonathan Karl Burkholz, S.
