Patent number: 10065029Abstract: A dilator may include a leading portion that includes a leading end coupled to a leading stem. The dilator may further include a trailing portion that includes a trailing end coupled to a trailing shaft. The dilator may also include a segmented body disposed between the leading end and the trailing end. The segmented body may include a plurality of segments disposed circumferentially around the leading stem. The leading stem may extend through a passageway of the segmented body, an opening of the trailing end and a channel of the trailing shaft. The leading stem and the trailing shaft may be configured to move longitudinally relative to one another to radially outwardly expand the segmented body.Type: GrantFiled: March 3, 2015Date of Patent: September 4, 2018Assignee: Cook Medical Technologies LLCInventors: Tyler J Bunch, Ram H Paul, Jr., Gary L Neff

Patent number: 9814490Abstract: An elongate access sheath comprises a proximal portion and a lumen. The proximal portion supports a control handle, a brake pad, a tension gear, and a locking trigger. A deflector filament extends through the lumen and is coupled to the tension gear. The tension gear includes an outside and an inner engagement portion. The brake pad comprises a slot and an outside engagement portion. The locking trigger includes a pin disposed within the brake pad slot. The control handle includes a lever and an engagement portion. Upward movement of the lever engages the engagement portion with the outside engagement portion of the tension gear to rotate the tension gear in a first direction and slides the deflector filament to bend the lumen distal portion. Translation of the locking trigger engages the brake pad and the tension gear to prevent rotation of the tension gear in an opposite second direction.Type: GrantFiled: October 22, 2014Date of Patent: November 14, 2017Assignee: Cook Medical Technologies LLCInventors: WenHong Neoh, Robert M. Eells, Jeffrey S. Melsheimer, Kristen Michelle Van Wyk, Tyler J. Bunch

Patent number: 8758231Abstract: In at least one embodiment of the present invention, an access sheath for positioning in a patient's body is provided. The access sheath comprises an elongated member having a proximal portion extending to a distal portion and a plurality of lumens formed therethrough including a working lumen and a first additional lumen. The first additional lumen is configured to receive an optical system or an irrigation system. The proximal portion has a stiffening section that includes a first coil and one of a braiding and a second coil which are disposed about the working lumen in concentric relationship with each other. The distal portion has a tip and a first deflection section and a second deflection section. The first deflection section is proximal to the tip and distal to the second deflection section. The first deflection section is configured to be actuated to bend at a first angle to position the tip. The second deflection section is configured to bend at a second angle to reposition the tip.Type: GrantFiled: May 12, 2010Date of Patent: June 24, 2014Assignee: Cook Medical Technologies LLCInventors: Tyler J. Bunch, Walter N. Ryan

Patent number: 8734426Abstract: A drainage catheter includes an elongated tubular member, a locking assembly engaged with a proximal end of the tubular member, and a tension member for drawing a distal end of the tubular member into a desired configuration. The locking assembly includes a connector, a locking arm, and a locking mechanism. The connector has an exterior surface profile that corresponds with an interior surface profile of the locking arm. The locking arm is pivotably attached to the connector to enable pivoting movement of the locking arm between an unlocked position and a locked position whereby the tension member is secured between the locking arm and the connector when the arm is in the locked position. The locking assembly may alternatively comprise a connector and a sliding sleeve or a connector having a clamping element disposed therein.Type: GrantFiled: October 15, 2010Date of Patent: May 27, 2014Assignee: Cook Medical Technologies LLCInventors: Mahfuza Ahmed, Tyler J. Bunch, Charles W. Agnew, Kate Duncan, James B. Hunt, Bonita L. Nickless, Nancy L. Hutchinson

Patent number: 7803130Abstract: A disposable access sheath having a deflectable tip is provided. The access sheath is very flexible and allows a physician or other medical professional to provide diagnostic or therapeutic services to a remote body cavity. The access sheath has a deflectable tip that is able to bend at least 90° or 180° or more. This flexibility allows the physician or medical professional to make a very tight turn to visualize or treat the body cavity being treated. The access sheath may include a visualization system, a working channel, an irrigation channel, or other desirable features. The access sheath may include an interface at the proximal end of the working channel for insertion of an instrument for diagnosis or treatment of a human or mammalian patient.Type: GrantFiled: January 4, 2007Date of Patent: September 28, 2010Assignees: Vance Products Inc., Sabin CorporationInventors: Walter N.
