Publication number: 20100070021Abstract: A stenting ring made of a tube or rolled-up sheet that has a characteristic wall thickness. The ring defines a lumen and is equipped with at least one marker made of a material different from that of the ring. The ring is expansible from a radially compact disposition with a relatively small circumference to a radially expanded disposition with a relatively large circumference. The ring exhibits in the compact disposition a serpentine arrangement of succeeding struts lying in alternate opposite directions to the longitudinal axis of the lumen. The marker has a thickness in the radial direction of the ring that is less than the characteristic wall thickness, and has a width that extends circumferentially around an arc of the ring. The marker is attached to the ring at a zone located at a point intermediate in the extent of said arc.Type: ApplicationFiled: December 5, 2007Publication date: March 18, 2010Applicant: C.R.

Publication number: 20100070016Abstract: A stent device delivery system, comprising a stent device pusher, a radially expandable stent device and an outer sheath. A tacky material provides a tackiness between the stent device pusher and an inner surface of the stent device. The tacky material is distributed along the length of the stent device. The tacky material serves to resist axial movement of the stent device relative to the stent device pusher as the outer sheath slides axially over the stent device, yet allows the stent device to peel from the tacky material and expand to a radially expanded state as the outer sheath slides axially over the stent device to release the stent device. The tacky material may be compressible such that the stent device is embedded in the compressible tacky material.Type: ApplicationFiled: September 15, 2009Publication date: March 18, 2010Applicant: C. R. Bard, Inc.Inventors: Juergen Dorn, Martina Hoffman, Beate Walter

Publication number: 20100036227Abstract: 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. Various aspects for visualizing and manipulating display of the ECG signal data acquired via the present system, together with aspects of various ECG sensor configurations, are also disclosed.Type: ApplicationFiled: September 10, 2009Publication date: February 11, 2010Applicant: C.

Patent number: 7654989Abstract: A ureteral access sheath comprises a sheath assembly having a main lumen and one or more secondary lumens. The sheath assembly can be configured with medical devices in both lumens, for example, a ureteroscope in the main working channel, and a guidewire, stone basket, grasper, laser fiber, or other surgical instrument in the secondary working channel. Or the sheath assembly can be configured with a medical device in one channel and the other lumen coupled to an irrigation means, such that irrigation of the surgical field can be efficiently accomplished even though the main working channel is substantially completely occupied by, e.g., a ureteroscope. Or the sheath assembly can be configured for irrigation through one lumen and aspiration through the other lumen, thereby creating a turbulent flow which washes the surgical field to facilitate removal of particles and debris.Type: GrantFiled: April 8, 2003Date of Patent: February 2, 2010Assignee: C.
