Patent number: 11338115Abstract: An angioplasty balloon (1) comprises an elongate tube (16) having a relaxed delivery configuration and an expanded deployed configuration. The elongate tube (16) comprises a proximal neck portion (10), a distal neck portion (8), a main body region, a tapered proximal portion (11) extending between the main body region and the proximal neck portion (10); and a tapered distal portion (9) extending between the main body region (3) and the distal neck portion (8), the elongate tube has only three fins (4, 5, 6) which are integrally formed with the tube and which are spaced equidistant from one another about the exterior of the tube. The fins (4, 5, 6) project radially outwardly from the exterior surface of the tube and the fins (4, 5, 6) extending longitudinally only along part of the main body region (3), resulting in the end-sections of the balloon main body being fin-free.Type: GrantFiled: September 29, 2017Date of Patent: May 24, 2022Inventors: David Slattery, John Joseph Kelly, Jonathan Akehurst, John Paul Culloty, Tomás Christopher Brosnan, David Fleming

Patent number: 11110250Abstract: A catheter (1) comprising an elongate tubular body (2) having a proximal end (3), a distal end (4), and an inner lumen (5) extending through the elongate tubular body (2), wherein the elongate tubular body (2) comprises a proximal section (6) and a distal section (7), wherein at least the proximal section (6) comprises at least two layers, wherein the proximal end (3) is connected with a catheter hub (8) being an adapter of greater radial outside dimension than the elongate tubular body (2), wherein the catheter hub (8) has an inner lumen (9) of larger inside diameter than the elongate tubular body (2), and wherein the innermost layer (10) of the proximal section (6) extends into the catheter hub (8) and flares from the proximal section (6) to the catheter hub (8). The catheter ensures a smooth transition of a medical device, e.g. a stent to be transferred from a storage device like a sheath into the tubular body of the catheter.Type: GrantFiled: March 5, 2019Date of Patent: September 7, 2021Assignee: Phenox Ltd.Inventors: Volker Trösken, Hermann Monstadt, Ralf Hannes, David Slattery, Ken Beatty

Patent number: 10835721Abstract: A delivery system includes a catheter, and a drug coated angioplasty balloon mounted on the catheter. The balloon has a wrapped or folded delivery configuration and an expanded deployed configuration. A protective sleeve surrounds the drug coated balloon in the delivery configuration to minimise wash-off of drug from the balloon during delivery. The protective sleeve is retractable, so that once the drug coated balloon is at or near the treatment site, the sleeve can be retracted to allow the drug coated balloon to operate effectively. The protective sleeve can have a spacer mounted to or integral with the protective sleeve. The spacer in one case can comprise of interior ribs or ridges on the sleeve which minimise the surface area of the sleeve in direct contact with the drug coating on the balloon.Type: GrantFiled: June 10, 2016Date of Patent: November 17, 2020Assignee: Merit Medical Ireland LimitedInventors: David Slattery, Jonathan Akehurst, David Kelly, John Joseph Kelly

Publication number: 20140324149Abstract: A delivery system for delivering a self-expanding medical device such as a stent. The delivery system includes a sheath profiled or shaped to reduce instances of interference between a distal edge of the sheath and a vessel or with any lesion or lesions that might be present in the vessel. The sheath is formed by modifying a cylinder of sheath material to include three portions and an initiation slit that controls the rupturing of the sheath to facilitate delivery of the medical device. The initiation slit is positioned on the delivery system with respect to a configuration of a balloon portion of the system.Type: ApplicationFiled: April 4, 2014Publication date: October 30, 2014Applicant: CAPPELLA, INC.Inventors: David Slattery, Damian Kelly, Therese O'Connor, Joseph Kerins, Michael Gilmore, Mark Steckel

Patent number: 8252035Abstract: A medical device delivery system provides for a two-stage withdrawal of a deflated balloon portion of a catheter and the remains of a ruptured sheath. The deflated balloon portion is withdrawn from within an expanded medical device a predetermined distance before the remains of the ruptured sheath begins being removed from between the expanded device and a vessel wall. Initiating removal of the deflated balloon portion before the sheath reduces a total amount of drag that is exerted against a self-expanding medical device that has been deployed in a vessel.Type: GrantFiled: August 1, 2007Date of Patent: August 28, 2012Assignee: Cappella, Inc.Inventors: Therese O'Connor, Michael Gilmore, David Slattery, Damian Kelly

Publication number: 20090093869Abstract: A device for implantation in a vessel is provided with a geometry designed to reduce the drag experienced by the device when deployed using a sheathed delivery system. Sections of the device are provided with regions of high-points and low-points on the device's outer surface by curving one or more of the struts of the device. The high points serve as the contact points of the device with the sheath as the sheath and the delivery system are withdrawn from between the device and the vessel.Type: ApplicationFiled: October 4, 2007Publication date: April 9, 2009Inventors: Brendan Cunniffe, Michael Gilmore, David Slattery, Damian Kelly

Publication number: 20080319388Abstract: A medical device delivery system includes a self-expanding medical device mounted on a balloon portion of a catheter. A sheath is provided around the medical device to hold the device in place with the device staying in a compressed state. A series of perforations or an initial cut is provided in the sheath at a predetermined location, or within a predetermined range of locations, on the circumference of the sheath. The predetermined location or range of locations are determined with respect to the folds of the balloon portion.Type: ApplicationFiled: June 21, 2007Publication date: December 25, 2008Inventors: David Slattery, Damian Kelly, Michael Gilmore, Mark Steckel
