Patent number: 10368977Abstract: The present embodiments describe an endograft having at least two branches extending from two fenestrations on the endograft body, and methods for deploying the same. In one example, the system comprises one internal branch that is relatively straight, and one external branch that is helically curved. The fenestrations may be circumferentially located on substantially the same side of the endograft main body, and distal regions of the branches may be circumferentially located on substantially opposite sides of the main body. The branches may be longitudinally non-overlapping. Connection stents may be configured to extend from the branches to provide fluid communication with peripheral vessels. Peripheral vessels may include the coronary or renal arteries. In another example, the branches are both external to the main endograft body.Type: GrantFiled: December 29, 2015Date of Patent: August 6, 2019Assignee: Cook Medical Technologies LLCInventors: Derek Eller, Jarin Kratzberg, Saylan Lukas

Patent number: 10206801Abstract: The present embodiments provide prosthesis deployment systems. In one embodiment, a sleeve has proximal and distal regions and a lumen extending therebetween, and further comprising a first exit aperture, a first entrance aperture, and a second exit aperture. A trigger wire is disposed at least partially within the lumen of the sleeve. A prosthesis has a delivery state and an expanded state, and further has first and second regions. In the delivery state, the trigger wire extends out of the lumen through the first exit aperture of the sleeve, restrains the first region of the prosthesis, reenters the lumen through the first entrance aperture of the sleeve, extends out of the lumen through the second exit aperture of the sleeve, and restrains the second region of the prosthesis.Type: GrantFiled: December 16, 2015Date of Patent: February 19, 2019Assignee: COOK MEDICAL TECHNOLOGIES LLCInventor: Derek Eller

Patent number: 10188538Abstract: An endovascular prosthesis delivery system is disclosed. The system comprises: an inner cannula; a prosthesis releasably secured to the inner cannula, the prosthesis having a radially-inwardly contracted delivery configuration and a radially-expanded deployed configuration, wherein the prosthesis comprises at least two suture loops secured to an outer surface of the prosthesis and circumferentially spaced from each other; a releasable trigger wire extending along at least a portion of the length of the prosthesis, wherein the releasable trigger wire is wound around at least a portion of the inner cannula and wherein the releasable trigger wire engages at least one of the at least two suture loops to retain the prosthesis in the radially-inwardly contracted delivery configuration.Type: GrantFiled: December 30, 2015Date of Patent: January 29, 2019Assignee: Cook Medical Technologies LLCInventors: Derek Eller, Saylon Lukas

Publication number: 20180243085Abstract: Selective fluid barrier valve devices and methods of treatment are described herein. An embodiment of a selective fluid barrier valve device comprises a housing, an actuator, a sleeve, a wire member, and a connector. The sleeve defines a passageway that extends through the sleeve. The actuator is moveable between a first position and a second position. When the actuator is in the first position, the sleeve is in a first configuration such that fluid can pass through the passageway defined by the sleeve. When the actuator is in a second position, the sleeve is in a second configuration such that fluid is prevented from passing through the passageway defined by the sleeve.Type: ApplicationFiled: April 24, 2018Publication date: August 30, 2018Inventor: Derek Eller
