Publication number: 20230263995Abstract: Systems and methods are described for removing an embolus in a cerebral vessel of a patient. The assembled system of devices includes a catheter having a catheter lumen and a distal end and a catheter advancement element extending through the catheter lumen. A tapered distal end region of the catheter advancement element extends distal to the distal end of the catheter. The assembled system of devices is advanced together towards an occlusion site in a cerebral vessel of a patient visible on angiogram. The occlusion site includes an angiographic limit of contrast and an embolus downstream of the angiographic limit of contrast. The catheter advancement element is advanced to a location past the angiographic limit of contrast without crossing the embolus. The catheter is advanced to position the distal end of the catheter at a treatment site located past the angiographic limit of contrast and aspiration applied.Type: ApplicationFiled: April 7, 2023Publication date: August 24, 2023Inventors: Tony M. Chou, Joey English, Warren T. Kim, Ian J. Clark

Patent number: 9585647Abstract: A closure element applying medical device for repairing a fistula is described. The closure element applying medical device can be configured for repairing any type of fistula that provides an abnormal channel from one body part to another body part (e.g., organ to organ, organ to vessel, and/or vessel to vessel). Examples of fistulas that can be repaired with the present invention include anorectal fistulas, enteroenteral fistulas, enterocutaneous fistulas, vesicovaginal fistulas, arteriovenous fistulas, perilymph fistulas, rectovaginal fistulas, ureterocolon fistulas, and the like. The medical device can include a closure element, a shaft, a carrier assembly, and controller systems. The medical device can also include a locator assembly. Additionally, the closure element applying medical device can include endoscope components so as to function also as an endoscope.Type: GrantFiled: November 12, 2014Date of Patent: March 7, 2017Assignee: ABBOTT LABORATORIESInventor: Ian J.

Patent number: 8858594Abstract: Devices and methods are disclosed herein for a closure device. A closure device includes a body movable from a pre-deployed configuration towards a deployed configuration, a plurality of tissue-engaging portions extending from the body. At least two of the tissue-engaging portions are separated by a first distance in the deployed configuration and a second distance in the pre-deployed configuration in which the first distance is smaller than the second distance. The closure device also includes a plurality of device capture features secured to the body. The device capture features are configured to move the tissue-engaging portions to a separation greater than the first distance.Type: GrantFiled: December 18, 2009Date of Patent: October 14, 2014Assignee: Abbott LaboratoriesInventor: Ian J.

Patent number: 8226681Abstract: Devices and methods for managing access through tissue is disclosed. The device includes a body. The body is movable from a pre-deployed configuration towards a deployed configuration. The device includes a plurality of tissue engaging portions that extend from the body. At least a portion of the tissue engaging portions are obtuse. At least two of the tissue engaging portions are separated by a first distance in the deployed configuration and a second distance in the pre-deployed configuration. The first distance is smaller than the second distance. The method includes deploying a closure element to tissue adjacent a tissue opening to substantially close the opening following a first procedure. The method also includes selectively opening the opening in the tissue by advancing a distal end of a medical device through the deployed closure element as a part of or before a second procedure.Type: GrantFiled: June 25, 2007Date of Patent: July 24, 2012Assignee: Abbott LaboratoriesInventors: Ian J.

Patent number: 7993303Abstract: A support catheter that can puncture a heart septum with a guidewire without buckling and that can access difficult to reach arteries such as carotid or renal arteries from the aorta under difficult circumstances is provided. The support catheter comprises a catheter body having a proximal end, a distal end, and an interior wall surface defining a first lumen extending from the proximal end toward the distal end. A second lumen is disposed between the interior wall surface and an outer surface of the catheter body. A plurality of stiffening members is disposed around the second lumen, the plurality of stiffening members being engageable to selectively stiffen the catheter body. In another configuration, the catheter further comprises a second plurality of stiffening members disposed between the first lumen and the second lumen.Type: GrantFiled: April 20, 2007Date of Patent: August 9, 2011Assignee: Abbott LaboratoriesInventors: Randolf Von Oepen, Ian J.
