Patent number: 10751204Abstract: Methods and apparatus are disclosed for customizing an elution rate of a stent. The stent includes a hollow strut that forms the stent, the hollow strut defining a lumenal space, a drug formulation disposed within the lumenal space of the hollow strut, and at least one side port for eluting the drug formulation in vivo. When the stent is in the radially expanded configuration the hollow strut is deformable from a first configuration that has a first elution rate for the drug formulation to a second configuration that has a second elution rate for the drug formulation. The second elution rate is faster than the first elution rate. The hollow strut deforms from the first configuration to the second configuration upon application of an applied pressure above a predetermined threshold.Type: GrantFiled: June 8, 2017Date of Patent: August 25, 2020Assignee: Medtronic, Inc.Inventors: Cian Ryan, David Hobbins, Shane Nolan, Michael Sayers, Eamon Keane, Brian Dowling, Jonathan Cope, Conor O'Donovan

Patent number: 10561510Abstract: Methods and apparatus are disclosed for customizing an elution profile of a stent after manufacture of the stent has been completed. The stent includes a plurality of side ports for eluting a drug formulation within a lumenal space of a hollow strut that forms the stent. An effective diameter of at least one side port of the plurality of side ports of the stent is modified in order to customize an elution profile of the stent. In an embodiment hereof, the plurality of side ports are completely blocked or plugged with a filler material during the manufacture of the stent and at least a portion of the filler material is removed to increase an effective diameter of at least one side port of the plurality of side ports of the stent in order to customize an elution profile of the stent.Type: GrantFiled: June 8, 2017Date of Patent: February 18, 2020Assignee: MEDTRONIC VASCULAR, INC.Inventors: Shane Nolan, David Hobbins, Michael Sayers, Eamon Keane, Brian Dowling, Jonathan Cope, Conor O'Donovan, Risa Egerter, Lana Woolley, Marc Anderson

Patent number: 9917994Abstract: A selectively attachable and removable visual and tactile assessment tool or clip for use with a mobile device is provided. Clip is an elongate member forming a curvilinear shape having a magnifying lens at a distal end thereof. Clip has a transparent tubular member disposed between first and second openings through the body portion of the clip. Tubular member has varying internal diameters to simulate, for example, the constriction or stenosis of a patient's vessel lumen. Once clip is attached to mobile device and the magnifying lens is positioned over the camera of the mobile device, a catheter is inserted through tubular member. The magnifying lens enlarges the size of the catheter displayed on the screen of the mobile device.Type: GrantFiled: November 13, 2015Date of Patent: March 13, 2018Assignee: Medtronic Vascular, Inc.Inventors: Barry O'Connell, Brian Dowling, James Smedley

Publication number: 20070191882Abstract: A surgical device and tool for use in stabilizing tissue, such as an organ relative to a clamp, the surgical device having an elongate rigid member with a proximal end of the device having a stabilizing structure that rests against the skin of the subject and includes a vessel guide for guiding a blood vessel attached to the organ or tissue, and a tapered distal end that mounts on the clamp. The surgical tool includes the combination of a clamp and the above-mentioned surgical device, with the clamp having a hinge pin with tapered socket that receives mounted the distal end of the device and a flap positioned on the proximal end. The tool is used to stabilize an organ by placement of the stabilizing structure against the skin of the subject, guiding a blood vessel with the vessel hook, using the flap to hold tissue away from the organ, and clamping such vessel distal to the vessel guide. A ligature is then placed across the vessel between the vessel guide and the clamp.Type: ApplicationFiled: February 5, 2007Publication date: August 16, 2007Inventor: Brian Dowling
