Publication number: 20070276428Abstract: An apparatus and method comprising at least one intragastric member made of a digestive-resistant or substantially indigestible material that is introduced into a bag located in the gastric lumen of a mammal for the treatment of obesity. One or more intragastric members are loaded into a delivery tube in a partially compacted first configuration and delivered to an overtube. The overtube includes a proximal end, a distal end and a lumen configured to receive the intragastric members in the first configuration for delivery to the bag located in the gastric lumen wherein the intragastric member is expanded to a second configuration. The apparatus further comprises a constraining element engaged with the bag to secure the intragastric member upon delivery into the gastric lumen.Type: ApplicationFiled: December 21, 2006Publication date: November 29, 2007Inventors: Frederick Haller, John Karpiel, Donagh O'Sullivan, Brian Rucker, Maximiliano Soetermans, William Voorhees

Publication number: 20070208218Abstract: An endoscopic wire guide apparatus for insertion through an insertion tube of an endoscope having an accessory port, the endoscope being configured for advancement into a patient. The apparatus comprises a wire guide disposed through the insertion tube for delivery into the patient. The wire guide has a distal portion and a proximal portion. The distal portion has a first diameter and the proximal portion has a second diameter less than the first diameter. The first diameter is more rigid than the second diameter. The second diameter is configured to allow the proximal portion to collapse when proximally extending through the accessory port of the endoscope and the distal portion extends at least partially beyond the distal end of the insertion tube.Type: ApplicationFiled: March 5, 2007Publication date: September 6, 2007Applicant: WILSON-COOK MEDICAL INC.Inventor: Frederick Haller

Publication number: 20070142702Abstract: A medical device for allowing a physician to unhand a scope or other instruments while maintaining control of the scope or other instruments during a medical procedure. The medical device includes at least one dock and a harness for attaching the dock to the physician's body. The harness can be adjustable, or sized to fit a specific physician. During a procedure, a physician outfitted with the medical device can place a scope and/or other instrument in the dock(s). Once the scope and/or other instrument is placed in the dock(s), the physicians hands are free to perform other procedures, while the physician continually controls the relative position of the scope with respect to the physician or the patient.Type: ApplicationFiled: November 29, 2006Publication date: June 21, 2007Applicant: Wilson-Cook Medical Inc. D/B/A Cook EndoscopyInventors: Frederick Haller, Kenneth Kennedy

Publication number: 20060142703Abstract: An elongate catheter shaft having a side port aperture through a side wall of the catheter shaft between proximal and distal ends of the shaft. The side port aperture is open to a lumen. Embodiments of the present invention are directed to stiffening structure disposed in the immediate vicinity of the side port aperture. The stiffening structures may be disposed on or be continuous with, for example, an exterior surface, an interior lumenal surface, within a wall of the catheter shaft, or some combination thereof. The stiffening structures described herein are directed to biasing the catheter shaft in the region of a side port aperture in a straight or curved configuration that resists undesired flexure in the region of the side port aperture.Type: ApplicationFiled: December 6, 2005Publication date: June 29, 2006Applicant: Cook IncorporatedInventors: Matthew Carter, Kenneth Kennedy, Frederick Haller, David Hardin, Cheri Matney, Brian Rucker, David Waller, Jacques Deviere, Patricia Chilton

Publication number: 20060030864Abstract: A method and apparatus for uncoupling a wire guide from and elongate medical device comprising a catheter shaft having a wire guide lumen extending there through, wherein the material surrounding the wire guide lumen is selected or adapted to facilitate splittability for removal of the wire guide. The catheter shaft is coextruded and comprises a plurality of materials. The portion of the shaft adjacent the wire guide lumen is formed from a first material and the balance of the shaft is formed from a second material. The first material is selected or adapted to facilitate splittability as compared to the second material. The first material may have a lower durometer than the second material. A peel tool for separating the wire guide from the catheter shaft is also provided.Type: ApplicationFiled: September 26, 2005Publication date: February 9, 2006Inventors: Kenneth Kennedy,, Matthew Carter, Frederick Haller, David Hardin,, David Waller, John Karpiel

Publication number: 20050143770Abstract: A method and apparatus for releasably securing a wire guide to an elongate medical device for introduction into a work site with the bodily lumen of a patient. An elongate engagement member is configured to engage the wire guide while it is coupled to the elongate medical device and is configured so as to prevent relative movement between the wire guide and the elongate medical device.Type: ApplicationFiled: December 7, 2004Publication date: June 30, 2005Inventors: Matthew Carter, Frederick Haller, Kenneth Kennedy, Brian Rucker, Stephen Deal, Juan Ayala

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

Patent number: 5786531Abstract: Internal combustion engine cylinder compression ratio measurement is provided by applying a train of pressure pulses to an engine cylinder, measuring time rate of change in pressure within the cylinder and estimating a volume of air within the cylinder from the measured time rate of change. The cylinder air volume may be compensated for such effects as change in cylinder air temperature away from a calibration temperature or cylinder leakage. The time rate of change in pressure is measured at an engine angular position corresponding to a known volume within the cylinder, for example an engine angular position corresponding to the cylinder top dead center position, and cylinder compression ratio is determined from the estimated volume of air in the cylinder and the known cylinder volume.Type: GrantFiled: February 27, 1997Date of Patent: July 28, 1998Assignee: General Motors CorporationInventors: Earl O.
