Patent number: 10363407Abstract: Embodiments include a fiducial deployment system with a handle configured for actuation of the same, the handle including a collet mechanism actuatable for controlled, one-at-a-time deployment of fiducials. A fiducial may include one or more protuberances configured to engage one or more slots in a needle of the system. The needle may be configured to deliver a plurality of fiducials to a target location in serial fashion, one at a time. In certain embodiments, echogenic placement of fiducials may present certain advantages. The handle includes an actuation mechanism with a collet and plunger actuation member configured for incrementally or otherwise controlledly deploy one or more fiducials at a time by advancing a sty let through and/or retracting the body of a slotted needle in which fiducials are disposed with a fiducial protrusion extending into the needle slot, which also includes retaining structures that do not impede the needle lumen.Type: GrantFiled: May 14, 2015Date of Patent: July 30, 2019Assignee: Cook Medical Technologies LLCInventors: Michael Clancy, Darach McGrath, Triona Campbell, Patrick Mulcahy, Fionan Keady, Ciaran Toomey

Patent number: 10299769Abstract: An endoscopic tissue-sampling needle includes an elongate needle shaft having a proximal and a distal shaft portion. The proximal shaft portion includes an inner tubular core that may be constructed of a same material as the distal shaft portion, having a longer length and a smaller outer diameter than the distal shaft portion. The distal shaft portion extends into and is fixedly attached to an inner diameter of a distal shaft portion lumen. The distal shaft portion lumen is configured for collection of patient tissue, with a distal penetrating tip and/or a side aperture with a cutting edge configured to excise tissue from a target site in a patient body. The proximal shaft portion includes polymer coating around the inner tubular core, which is configured to provide an outer diameter for the proximal shaft portion that may be substantially the same as the outer diameter of the distal shaft portion.Type: GrantFiled: June 3, 2015Date of Patent: May 28, 2019Assignee: Cook Medical Technologies LLCInventors: Ciaran Toomey, Darach McGrath, Michael Clancy, Triona Campbell

Patent number: 10092388Abstract: A prosthesis and a method for directing flow through a passageway formed between a first bodily lumen and a second bodily lumen are provided. The prosthesis includes a body having a proximal portion, a distal portion and a lumen extending therethrough. The prosthesis also includes a sleeve operably connected to the body at a connected portion. The sleeve has a proximal portion, a distal portion, and a sleeve lumen extending therethrough. At least a portion of the body is positioned within at least a portion of the sleeve lumen and the distal portion of the sleeve is free from connection to the distal portion of the body and extendable away from the body to contact a wall of the first bodily lumen. The sleeve is configured to allow fluid flow through the sleeve lumen from the first bodily lumen to the second bodily lumen.Type: GrantFiled: November 12, 2015Date of Patent: October 9, 2018Assignee: Cook Medical Technologies LLCInventor: Ciarán Toomey

Patent number: 9855403Abstract: A medical device includes an elongate single-wire memory-metal body with a complete length that includes a proximal stylet length, an intermediate self-coiling stylet length, and a distal stylet length that is generally straight and non-self-coiling. The moment of force of the self-coiling stylet length is less than the moment of force of the medical endoscopy needle that is resistant to the stylet's self-coiling force. The device may further include being incorporated into an endoscopy needle system where the single-wire stylet body is disposed through a lumen of a medical endoscopy needle.Type: GrantFiled: October 16, 2013Date of Patent: January 2, 2018Assignee: Cook Medical Technologies LLCInventors: Nathaniel A. Irwin, Michael S. Clancy, Darach McGrath, Ciarán Toomey, Ronan Leahy, Fionan Keady

Patent number: 9782153Abstract: A notched tissue-collection needle configured similarly to a fine-needle-aspiration needle is provided with a cutting edge disposed in the notch and configured to excise tissue into the notch for collection. A stylet may be provided through a lumen of the needle during introduction into a patient body. The needle may be provided with echogenicity-enhancing features. A coated-coiled-wire sheath through which the needle is slidably disposed includes an overcoating that is thicker along a distal length and thinner along a mid-section length intermediate the proximal and distal lengths, and may include another thicker proximal-most portion adjacent the handle.Type: GrantFiled: February 21, 2017Date of Patent: October 10, 2017Assignee: Cook Medical Technologies LLCInventors: Ronan Leahy, Michael Stephen Clancy, Ciaran Toomey

Patent number: 9750532Abstract: Access needles and methods of using the needles are set forth in this disclosure. The needles can include a handle and a cannula having a proximal end operatively connected to the handle, a distal end, and a lumen extending through the body of the cannula. A protective sheath may surround the cannula. Further, a stylet may be removably disposed within the lumen of the cannula. The stylet includes a piercing tip at a distal end and a flexible body length extending proximally from the piercing tip to the handle. The flexible body of the stylet provides a path of fluid communication through the lumen of the cannula such that a contrast fluid can effectively pass through the lumen of the cannula. Methods of introducing cannulas to target locations within a body of a patient are also set forth in this disclosure.Type: GrantFiled: May 14, 2014Date of Patent: September 5, 2017Assignee: Cook Medical Technologies LLCInventors: Ciarán Toomey, Michael Dunning, Fionan Keady

Patent number: 9089359Abstract: The present embodiments provide apparatus and methods for facilitating endoscopic resection of tissue. In one embodiment, the apparatus comprises a first tube having proximal and distal regions, and a working lumen disposed within at least a portion of the distal region. A second tube is disposed circumferentially around at least a portion of the distal region of the first tube. A wire has a distal end that is securely attached to a distal region of the second tube. In use, rotation of the second tube relative to the first tube causes the wire to pass circumferentially over a distal face of the first tube to incise tissue disposed within the working lumen of the first tube.Type: GrantFiled: December 17, 2012Date of Patent: July 28, 2015Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Ciaran Toomey, Kieran Costello

Patent number: 8955520Abstract: A dual lumen catheter may be provided with one or more stents in a stent-deployment lumen and a wire guide disposed through a wire guide lumen. The wire guide may be directed to a target site in a patient body such as a biliary stricture. The catheter may be directed along the wire guide until it is in or adjacent the target site. A distalmost stent may be advanced out a distal side-facing aperture of the stent-deployment lumen into the target site by a pusher member that advances the stent or that holds the stent in place while the catheter is proximally withdrawn from around the stent. With the wire guide remaining substantially in place, the stent-deployment lumen can be reoriented and the steps repeated to place a second (and, if desired, subsequent) stent(s) next to—and generally parallel with—the first stent.Type: GrantFiled: July 19, 2012Date of Patent: February 17, 2015Assignee: Cook Medical Technologies LLCInventors: Paul Devereux, Ciarán Toomey, Sharon White
