Publication number: 20070239103Abstract: The present invention provides a medical system comprising an elongated medical device having a longitudinal lumen, such as a catheter or a needle, and a stylet configured to be inserted into and subsequently removed from the longitudinal lumen. The stylet is configured to have at least one indicator that indicates that the distal end of the stylet is about to exit the lumen as the stylet is being withdrawn during use. Each indicator alerts the user that the stylet is almost completely withdrawn from the lumen such that the user may take proper precautions and prevent the stylet from inadvertently and uncontrollably exiting the lumen. Each indicator may be located in the proximity of the distal end of the stylet and present either a visual, physical, or audible indication. Additionally, the present invention provides a method that indicates the longitudinal position of a stylet relative to an elongated medical device.Type: ApplicationFiled: December 7, 2006Publication date: October 11, 2007Inventors: David Hardin, Victor Clark, Rig Patel

Publication number: 20060247530Abstract: An endoscopic ultrasound-guided system and method for monitoring the location of a device contained within intraluminal and extraluminal regions of a patient is described. The endoscopic ultrasound-guided system includes a linear echoendoscope, a device, and a wire guide. The device and wire guide contain echogenic surfaces which enable transducers placed at the distal end of the linear echoendoscope to ultrasonically monitor the location of the devices. When the echogenic surface of the device encounters incident ultrasound waves emitted from a series of linear array transducers, a real-time ultrasonic image of the device is generated as the incident ultrasound waves reflect off the echogenic surfaces and propagate back towards the transducers. The surgeon receives the real-time ultrasonic image of the device and then can determine the location of the device within the intraluminal or extraluminal region of the patient.Type: ApplicationFiled: February 28, 2006Publication date: November 2, 2006Applicant: Wilson-Cook Medical Inc.Inventors: David Hardin, Kenneth Kennedy, Brian Rucker, Gregory Skerven

Publication number: 20050070794Abstract: A method and apparatus for introducing a first elongate medical device and short wire guide that are coupled together into a work site and remotely disconnecting them within the work site such that a secondary device comprising a catheter member can be introduced over the wire guide to the work site, and/or a second wire guide can be introduced to the work site via a passageway of the primary access device. A system of indicia, such as radiopaque or viewable markers, permits the operator to monitor the relative alignment of the devices within the work site to determine when uncoupling has occurred. In one example of the method, a wire guide and primary access device (e.g., a sphincterotome) is coupled to the wire guide and introduced via a duodenoscope into the biliary system. After performing a first medical operation, the devices are uncoupled with the wire guide being left within the biliary system such that a secondary access device, such as a balloon, biopsy device, stent delivery catheter, dilator, etc.Type: ApplicationFiled: July 29, 2004Publication date: March 31, 2005Inventors: Stephen Deal, Matthew Carter, Frederick Haller, David Hardin, Kenneth Kennedy, Brian Rucker, Gregory Skerven, David Waller
