Patent number: 11291573Abstract: A delivery system is provided for self-expanding medical devices, such as stents. The delivery system has a restraining sheath that maintains the stent in a compressed state prior to deployment. The restraining sheath terminates distally from the deployment handle, and a wire connects the restraining sheath to the deployment handle. The restraining sheath is withdrawn from the stent to deploy the stent by pulling the wires proximally at the deployment handle.Type: GrantFiled: March 13, 2014Date of Patent: April 5, 2022Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Sean Cummins, Dean R. Puckett, Brent A. Mayle, James C. Merk, Tawnya Wood, Tiffani L. Cannon

Patent number: 10182834Abstract: A method of treating a thrombus is provided wherein a device is advanced to the vicinity of the thrombus, a thrombolytic agent is applied to the thrombus, and an expandable basket of the device is expanded to capture at least a portion of the thrombus within the expandable basket. The device includes a catheter having a distal portion, a lumen and a plurality of openings on the outer surface of the catheter, through which the thrombolytic agent is supplied. The device further includes a sheath and may include a collar which assists in expanding the expandable basket as the sheath is moved relative to the catheter.Type: GrantFiled: January 8, 2016Date of Patent: January 22, 2019Assignee: Cook Medical Technologies LLCInventors: James C Merk, Dean R Puckett, Darin J Voorhies, Brent A Mayle, Keith R Milner

Publication number: 20180296379Abstract: A medical instrument is provided including, an expandable tip which is embedded within a sheath. The expandable tip comprises a plurality of fingers which extend distally from the embedded portion. The plurality of fingers are heat set in a first position so that the distal ends of the fingers define a distal opening, where the distal opening has a smaller diameter than the embedded portion of the expandable tip. The plurality of fingers is reversibly expandable to a second position, creating a larger distal opening to deploy an expandable accessory.Type: ApplicationFiled: June 21, 2018Publication date: October 18, 2018Applicant: Cook Medical Technologies LLCInventors: Dean R. Puckett, Brent A. Mayle
