Patent number: 9789278Abstract: A catheter assembly includes a catheter, a collar, and an extension tube assembly. The catheter includes a leading end portion and a trailing end portion. The collar is supported on the trailing end portion of the catheter. The extension tube assembly includes a first section and a second section, each section independent of the other section and including a substantially rigid body portion and a compressible extension tube portion. The body portion of each of the first and second sections is independently engageable with the trailing end portion of the catheter. The collar is configured to engage the first and second sections of the extension tube assembly to secure the extension tube assembly to the trailing end portion of the catheter.Type: GrantFiled: September 20, 2012Date of Patent: October 17, 2017Assignee: Covidien LPInventors: Kurt Haggstrom, Robert Frechette

Patent number: 9713694Abstract: A medical catheter assembly includes a catheter hub, an elongate catheter member extending from the catheter hub and having at least one longitudinal lumen for passage of fluids, an extension tube extending from the catheter hub and defining an internal lumen in fluid communication with the at least one longitudinal lumen of the catheter member and a clamp positionable about the extension tube. The catheter hub defines a reduced profile to facilitate passage of the catheter hub through a surgical tunnel. The clamp includes first and second clamp sections and defines a longitudinal clamp axis. The clamp has a longitudinal opening for passage of the extension tube and a movable member adapted to move from a first position to a second position to substantially close the internal lumen. The first and second clamp sections are separable to facilitate transverse positioning of the clamp sections about the extension tube.Type: GrantFiled: April 2, 2013Date of Patent: July 25, 2017Assignee: Covidien LPInventors: Richard Braga, Robert Frechette, Brett Haarala

Patent number: 7182746Abstract: A catheter is provided including a tubular body having a proximal end and a distal end. The body includes a first lumen and a second lumen with a septum disposed therebetween. The proximal end includes a valve and a hub that are integral with the body. The hub includes a first conduit and a second conduit. The valve includes a first port and a second port that are rotatable, about a longitudinal axis of the body, to establish fluid communication between the lumens and the conduits. The distal end of the tubular body may be configured for insertion with a subject. The conduits may be connectable to a medical apparatus.Type: GrantFiled: February 11, 2005Date of Patent: February 27, 2007Assignee: Sherwood Services AGInventors: Brett Haarala, Robert Frechette, Kurt Haggstrom, Scott MacMeans, Elise Tordella
