Patent number: 9895227Abstract: An expandable prosthesis having an imageable structure comprising one or more elements visually distinguishable by an external (e.g., radiographic or ultrasonic) imaging system, the structure being located about a first axis that corresponds to a structural feature of the prosthesis that is configured to perform a specific function particular to that axis. The imageable structure is configured to assist in the rotational orientation of the prosthesis during placement within the implantation site. In one embodiment, the prosthesis comprises a venous valve that includes imageable elements or structure, such as a pair of radiopaque markers, that defines the orifice of the valve structure such that the orifice can be oriented with a particular anatomical feature under imaging, such as to align the orifice with the long axis of the vessel.Type: GrantFiled: April 11, 2012Date of Patent: February 20, 2018Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Brian C. Case, Jacob A. Flagle, Michael L. Garrison, Andrew K. Hoffa, Ray Leonard, II

Patent number: 9421096Abstract: An expandable venous valve having a support structure that is configured to enlarge the area adjacent to the valve structure such that the flow patterns of retrograde flow are modified in a way that facilitates the flushing of the pockets at the base of the valve area to prevent stagnation of bodily fluid, which in the venous system, can lead to thrombus formation. The enlarged pocket areas can be created by forming an artificial sinus adjacent the valve structure in an unsupported section of vessel wall between two support frame sections or the support frame can comprise an expanded-diameter intermediate or proximal section that forms an artificial sinus adjacent the valve structure.Type: GrantFiled: July 16, 2012Date of Patent: August 23, 2016Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Brian C. Case, Michael L. Garrison, Andrew Hoffa, Darin G. Schaeffer, Jacob A. Flagle

Patent number: 8444666Abstract: A filter may have an apical hub and a plurality of divergent legs. A first attachment member may be separate from, but attached to the second end of at least one of the plurality of divergent legs. A second attachment member may be separate from, but attached to a stent. The first and second attachment members may be separate from, but attachable to one another to releasably attach the filter to the stent. One of the first attachment member and the second attachment member may include an attachment wire that is positioned in a lumen of a tubular member or one of the first attachment member and the second attachment member may comprise a cannula. In some implementations, an upward motion applied to the retrieval connection member may disengage at least one attachment wire of the first attachment member from the second attachment member.Type: GrantFiled: September 12, 2003Date of Patent: May 21, 2013Assignee: Cook Medical Technologies LLCInventors: Dusan Pavcnik, Brian C.

Patent number: 7955376Abstract: A medical device comprises a support structure and one or more graft members comprising a valve portion and a constraining portion. The support structure has a first, unexpanded configuration and a second, expanded configuration. The constraining portion is adapted to substantially prevent the support structure from achieving the second, expanded configuration. The valve portion is adapted to permit fluid flow through a body vessel in a first direction and substantially prevent fluid flow through the vessel in a second, opposite direction.Type: GrantFiled: October 10, 2006Date of Patent: June 7, 2011Assignee: Cook Medical Technologies LLCInventors: Thomas A.

Patent number: 7909862Abstract: Methods and devices for delivering and deploying expandable intraluminal medical devices at a desired point of treatment within a body vessel are provided. A delivery device is provided, inserted into a body vessel, and navigated through the vessel to place an associated expandable intraluminal medical device at a desired point of treatment. Once the desired location is reached, an elongate member on which the expandable intraluminal medical device is disposed is spaced from a wall surface of the body vessel using an expandable wire basket, balloon, or other suitable structure. The expandable intraluminal medical device is deployed from the delivery system, which can ultimately be withdrawn from the body vessel.Type: GrantFiled: March 19, 2004Date of Patent: March 22, 2011Assignee: Cook Medical Technologies LLCInventors: Michael L.

Publication number: 20100057191Abstract: An valve prosthesis, such as an artificial venous valve, having a support frame and leaf structure comprising one or more leaflets in which the outer edge of each leaflet engages the inner circumference of the bodily passageway along a serpentine path urged against the passageway by an expandable frame, while the inner edges move in response to fluid to restrict retrograde flow. Optionally, one or more elements can extend from the support frame/leaf structure to provide centering support and/or protection from the leaflet adhering to the vessel wall. In one embodiment, the centering support structure comprises a second or third expandable frames attached to and extending from the proximal and/or distal ends of main valve structure and support frame. In another embodiment, one or more support elements extend outward from the valve support frame to engage the vessel wall to provide greater longitudinal stability.Type: ApplicationFiled: October 7, 2009Publication date: March 4, 2010Inventors: DUSAN PAVCNIK, THOMAS A.
