Publication number: 20150196392Abstract: 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: January 16, 2014Publication date: July 16, 2015Applicant: Cook Medical Technologies LLCInventors: John C. Sigmon, Jr., Jillian Haac, Michelle D. Martinez, Shaun D. Gittard, Devesh Amatya, Vihar C. Surti

Patent number: 9060779Abstract: The present embodiments provide systems and methods for deploying at least one clip device. In a first embodiment, the system comprises a first clip device having first and second arms. The first clip device and an associated sliding ring are configured to be selectively advanced through a lumen of an inner catheter. Selective positioning of an outer catheter over a distal region of the inner catheter causes a distal region of the inner catheter to bow radially inward to form a constriction that securely engages the sliding ring of the first clip device, thereby allowing for partial closure and repositioning of the first clip device. In an alternative embodiment, a delivery system includes a single catheter having a tapered distal region, such that upon ejection of the sliding ring from the distal end of the catheter, the sliding ring is dimensioned to abut the distal end of the catheter. In any of the embodiments, multiple clips may be sequentially loaded and deployed using the delivery systems.Type: GrantFiled: August 3, 2011Date of Patent: June 23, 2015Assignee: COOK MEDICAL TECHNOLOGIES LLCInventor: Michelle D.

Publication number: 20140163317Abstract: 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: ApplicationFiled: December 6, 2013Publication date: June 12, 2014Applicant: Cook Medical Technologies LLCInventors: John C.

Publication number: 20120209070Abstract: 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: February 29, 2012Publication date: August 16, 2012Applicant: COOK MEDICAL TECHNOLOGIES LLCInventors: David Keith Piech, Deepthi Jampala, Vihar C.
