Publication number: 20180125573Abstract: A bipolar sphincterotome may include an elongate tubular member, a cutting wire, and a return path. The return path may include a conductive ink portion disposed on an outer surface at a distal portion of the tubular member. The return path may also include a return wire disposed within the tubular member that is electrically coupled to the conductive ink portion. In some example embodiments, the return wire may be disposed within a lumen configured to have two or more functions, one of which being to house the return wire. Additionally, in some example embodiments, the conductive ink portion may be circumferentially disposed on the outer surface to provide visual access to a wire guide lumen. Also, for some example embodiments, the bipolar sphincterotome may include two electrically isolated return paths.Type: ApplicationFiled: December 18, 2017Publication date: May 10, 2018Applicant: Cook Medical Technologies LLCInventors: Tyler Evans McLawhorn, Vihar C.

Publication number: 20170143942Abstract: A valve insertion device for traversing a wire guide through a valve within an intraluminal passage. A wire guide is positioned near the outflow of a valve within an intraluminal passage. Alongside the wire guide, a pressure sensor is positioned to detect the pressure of the fluid in the intraluminal passage. As the valve opens, the fluid pressure at the outflow of the valve increases. This information is sent from the pressure sensor to a control system. From this information, the control system can determine when the valve will open and can actuate an advancement system to move the wire guide to traverse the open valve. After traversing the valve, various catheters and sheaths may be advanced over the wire guide through the valve.Type: ApplicationFiled: December 6, 2016Publication date: May 25, 2017Inventors: John C. Sigmon, JR., Jillian Haac, Michelle D. Martinez, Shaun D. Gittard, Devesh Amatya, Vihar C. Surti

Publication number: 20170042609Abstract: A conductive coating may be adhered to a structure comprising a hydrophobic and/or adhesion-resistant surface. The conductive coating may have a polymer backbone with conductive particles suspended in the backbone. In some embodiments, the conductive coating may be applied directly to the surface. In other embodiments, the conductive coating may be indirectly applied by first applying a primer adhesive to the outer surface, and then applying the conductive coating over the primer adhesive. An example structure may be a catheter of an endoscopic medical device, such as a bipolar sphincterotome, where the conductive coating functions as a return electrode.Type: ApplicationFiled: October 31, 2016Publication date: February 16, 2017Applicant: Cook Medical Technologies LLCInventors: Shaun Gittard, Gregory J.

Publication number: 20170035594Abstract: The present disclosure provides a support device for a gastrointestinal implant. The support device may include a lumen configured to extend through a submucosal tunnel and a mouth located at a proximal end of the lumen and in fluid communication with the lumen. The mouth may be configured to face proximally within a gastrointestinal tract to receive GI contents, and the mouth may be configured to direct the GI contents into the lumen. The support device may further include a support structure, where the lumen extends through the support structure, and where the support structure is configured to apply an outward radial force on an inner wall of the gastrointestinal tract. An artificial tunnel may extend distally from the support structure, may form at least a portion of the lumen, and may be configured to extend through the submucosal tunnel.Type: ApplicationFiled: August 2, 2016Publication date: February 9, 2017Applicant: Cook Medical Technologies LLCInventors: John Crowder Sigmon, JR., Greg James Hardy, Shaun D.

Patent number: 9451875Abstract: A flexible lens is mounted to the end of an elongate medical device having a camera, such as an endoscope. The lens is generally solid and is made from a translucent, flexible, and resilient material. In a medical environment, the lens can be pressed against a vessel wall in a patient to enlarge the area viewed by the camera, and can further adapt to the shape of the wall to limit trauma on the patient. When pressed against the vessel wall, the lens can become longitudinally compressed, while becoming wider. The wider and compressed shape of the lens will push blood away from the viewing area to increase the clarity of the camera's field of view.Type: GrantFiled: December 6, 2013Date of Patent: September 27, 2016Assignee: Cook Medical Technologies LLCInventors: John C.

Publication number: 20160227995Abstract: A medical system generally comprises a camera head, a beam, and a guide sheath. The camera head is connected to the beam which is bendable in a first direction and resists bending in a second direction opposite the first direction. The guide sheath slidably receives the beam, the beam extending through a distal end of the guide sheath such that the camera head projects from the distal end of the guide sheath. The guide sheath includes first and second sheath portions, and in an operative configuration the first sheath portion is angled relative to the second sheath portion to define a first bend. The beam is oriented relative to the guide sheath such that, as the beam is slid relative to guide sheath, the beam bends in the first direction through the first bend, and a projecting portion of the beam resists bending in the second direction.Type: ApplicationFiled: April 15, 2016Publication date: August 11, 2016Inventors: David Keith Piech, Deepthi Jampala, Vihar C.
