Patent number: 8535272Abstract: A catheter includes a proximal end, a distal end, a tubular member, and an inner member extending through the tubular member. The inner member is movable axially relative to the tubular member. The catheter also includes a seal member including a first portion and a second portion. The seal member extends between the tubular member and the inner member. The first portion of the seal member remains stationary relative to the tubular member, and the second portion of the seal member remains stationary relative to the inner member during relative axial movement between the tubular member and the inner member.Type: GrantFiled: April 30, 2012Date of Patent: September 17, 2013Assignee: St. Jude Medical, Atrial Fibrillation Division, Inc.Inventors: Huisun Wang, Dale Just

Patent number: 8500717Abstract: The present invention relates to a connection piece for an enteral transfer system and to an enteral transfer system with such a connection piece, and also to an arrangement composed of such a transfer system and of an enteral feed probe. The connection piece according to the present invention comprises a distal attachment piece for attachment of a connection piece of a probe tube of an enteral feed probe, and a proximal attachment piece for attachment of the connection tube of a transfer system. The distal attachment piece of the connection piece is conical or is designed in stepped fashion with several portions of different diameter. The distal attachment piece can therefore be releasably connected to the funnel-shaped connection pieces of different diameter of the probe tubes of the known feed probes. The connection piece according to the present invention can be used universally in this respect.Type: GrantFiled: October 23, 2007Date of Patent: August 6, 2013Assignee: Fresenius Medical Care Deutschland GmbHInventor: Michael Becker

Patent number: 8454579Abstract: Some embodiments disclosed herein relate to a medical connector having a backflow resistance module configured to prevent fluid from being drawn into the connector when a backflow inducing event occurs. In some embodiments, the backflow resistance module can include a variable-volume chamber configured to change in volume in response to a backflow-inducing event and a check valve configured to resist backflow. In some embodiments, the medical connector can include a fluid diverter configured to direct fluid flowing through the medical connector into the variable volume chamber to prevent fluid stagnation therein. In some embodiments, the medical connector includes a body member, a base member, a seal member, a support member, and a valve member.Type: GrantFiled: March 23, 2010Date of Patent: June 4, 2013Assignee: ICU Medical, Inc.Inventor: Thomas F. Fangrow, Jr.

Patent number: 8449528Abstract: A connector for coupling to a base of an indwelling device equipped with a circular hub having a radius, a top surface, a side surface, and a circumferential recess defined in the side surface. The connector has a resilient assembly including a plurality of release buttons extending from the resilient assembly and may include a conduit defining a fluid pathway through the connector. Each release button has a finger contact zone and a catch. The catch is configured to releasably engage the circumferential recess. The connector is coupled by positioning the connector on the circular hub and depressing the connector until the catches engage the circumferential recess such that the connector is configured to rotate completely about the circular hub. The connector is decoupled from the hub by pressing the release buttons to reversibly displace the respective catches radially to disengage from the circumferential recess.Type: GrantFiled: December 23, 2010Date of Patent: May 28, 2013Assignee: Kimberly-Clark Worldwide Inc.Inventors: Nathan C. Griffith, Donald J. McMichael, John A. Rotella, Scott M. Teixeira

Publication number: 20130085381Abstract: An infusion catheter assembly has the ability to infinitely titrate the length of a porous fluid distribution section in situ. The infusion catheter assembly thereby provides a length of infusion that can be infinitely varied over a prescribed range, to control the effective infusion length and the rate of infusion. Using the infusion catheter assembly, a physician has the capability to treat only the length of the vessel desired, thereby preventing excessive drug/patient exposures. The porous fluid distribution section can include an array of spaced apart apertures that vary in size and/or density along the length of the porous fluid distribution section, such that the flow rate remains essentially constant for a given inlet pressure independent of the effective infusion length.Type: ApplicationFiled: August 1, 2012Publication date: April 4, 2013Applicant: Venous Therapy, Inc.Inventors: Anthony J.
