Patent number: 7875003Abstract: In a pre-filled Foley catheter for urine drainage, the conventional clip for releasing sterile water from a bulb (21) at the proximal end of the catheter, to fill the anchor bulb (20) at the distal end of the device, is replaced by a plug (25) which has an annular portion connected to a thin stem (27) by a circle of weakness. Snapping the stem (27) from the annulus provides a tactile signal through the opaque latex lumen that the catheter has been actuated. There is no separate clip to be disposed of. The interface between the latex and the plug remains undisturbed. Further improvement in the shelf-life and convenience of use of the catheter is delivered by the use of a sleeve, which can be of shrink-wrap material, around the bulb (21) and optionally also around the drain coupling (15) of the catheter. Apparatus for placing the plug and the sleeve is also described.Type: GrantFiled: November 29, 2005Date of Patent: January 25, 2011Assignee: C. R. Bard, Inc.Inventors: Roger Howard Meek, David Evans

Publication number: 20110015533Abstract: An integrated catheter placement system for accurately placing a catheter within a patient's vasculature is disclosed. In one embodiment, the integrated system comprises a system console, a tip location sensor for temporary placement on the patient's chest, and an ultrasound probe. The tip location sensor senses a magnetic field of a stylet disposed in a lumen of the catheter when the catheter is disposed in the vasculature. The ultrasound probe ultrasonically images a portion of the vasculature prior to introduction of the catheter. ECG signal-based catheter tip guidance is included in the integrated system to enable guidance of the catheter tip to a desired position with respect to a node of the patient's heart. Stylets and catheters including various multiple bipolar and monopolar electrode configurations are also disclosed.Type: ApplicationFiled: September 29, 2010Publication date: January 20, 2011Applicant: C.R.

Publication number: 20100331823Abstract: A proximally trimmable catheter is disclosed. In one embodiment, the catheter includes a multi-lumen catheter tube, one or more extension tubes, and a hub for fluidly connecting the two. In a first unlocked state, the hub is axially slidable along the catheter tube. The hub includes tube pins that are in fluid communication with the extension tubes. A cutting member is positioned to longitudinally cut the catheter tube during axial sliding of the hub along the catheter tube such that distal portions of the tube pins remain disposed within the lumens of the catheter tube. When positioned as desired, the hub is locked into a second locked state and is no longer axially slidable along the catheter tube. The tube pins are fluidly sealed within the lumens of the catheter tube as to establish fluid communication between the extension tubes and the lumens via the tube pins.Type: ApplicationFiled: June 25, 2010Publication date: December 30, 2010Applicant: C.
