Patent number: 11304835Abstract: The invention provides an inflatable insertion device capable of being percutaneously introduced into a patient's body. The insertion device comprises an inflatable element having a distal end and a proximal end and which is operable between a collapsed condition and an inflated condition by introducing an inflating fluid therein. An elongate member extends internally of the inflatable element from its distal end. The internal member is capable of being withdrawn towards the proximal end of the inflatable element to result in the distal end of the element being withdrawn towards the proximal end internally of the element. The invention further provides a locating device comprising a catheter having a catheter tube fitted with one or more inflatable insertion devices at a distal end thereof.Type: GrantFiled: March 1, 2017Date of Patent: April 19, 2022Assignee: Strait Access Technologies Holdings (PTY)Inventors: Giuseppe Geldenhuys, Fourie Gildenhuys, Braden Sydney Clive Van Breda, Kenneth Stuart Park, Carl Nick Van Zyl, Jandré De Villiers, Peter Paul Zilla, Deon Bezuidenhout

Patent number: 11033388Abstract: The invention provides a non-occlusive dilation and deployment catheter device which includes a catheter having a distal end configured for entering a patient and a proximal end for manipulating the device. A distender is provided at or near the distal end which is movable between a collapsed configuration which enables introduction and removal thereof to and from an operative site in a vessel or other hollow organ of a patient, and an expanded configuration in which the distender assumes a radially expanded condition and defines a flow path therethrough. The distender includes a substantially tubular, radially expandable frame having a plurality of spaced apertures and at least one inflatable tube threaded through the apertures and shaped to extend in a spiral when inflated. The distender is movable to the expanded configuration by inflating the tube, and movable to the collapsed configuration from the expanded configuration by deflating the tube.Type: GrantFiled: May 5, 2016Date of Patent: June 15, 2021Assignee: Strait Access Technologies Holdings (PTY) LtdInventors: Thomas Gerhardt, Peter Rudi Haw, Jeremy Douglas Jarman, Giuseppe Geldenhuys, Kenneth Stuart Park, Braden Sydney Clive Van Breda, Edward Charles Mudge, Deon Bezuidenhout, Peter Paul Zilla

Patent number: 10792149Abstract: An expandable stent comprises a cylindrical wall made up of lattice members connected to each other, at least one first arm and at least one second arm. The first arm comprises: a first non-linear member that is connected at each of its axial ends to a lattice member at respective first junctions; a second non-linear member connected at each axial end to a lattice member; and at least one bridge member extending between the first member and the second member. The second arm comprises: a first non-linear member that is connected at each of its axial ends to a lattice member; a second non-linear member connected at each axial end to a lattice member; and at least one bridge member extending between the first member and the second member. The second member of the first arm is generally U-shaped, extending from its axial ends towards: (i) a first axial end of the stent; and (ii) towards the bridge of the first arm.Type: GrantFiled: April 26, 2017Date of Patent: October 6, 2020Assignee: Strait Access Technologies Holdings (Pty) LtdInventors: Grant Leigh Nelson, Kenneth Stuart Park, Braden Sydney Clive Van Breda, Deon Bezuidenhout, Peter Zilla, Harish Appa

Publication number: 20200254229Abstract: This invention relates to an airway dilation device comprising a catheter; an inflation tube within the catheter, and having a lumen defined by its inner wall; a duct within the catheter, for the insufflation of a fluid, the duct being sealed against any fluid flow between it and the tube; a cluster of balloons, arranged about the catheter, the balloons being manipulated between a stowed condition, in which the balloons are deflated, and a deployed condition, in which the balloons are inflated; and inflating means, for inflating the balloons; characterised in that, when stowed, each balloon is folded and staggered relative to each adjacent balloon, and such that continuous insufflation remains possible, even when deployed. This invention relates, further, to corresponding methods of deployment of devices.Type: ApplicationFiled: April 28, 2020Publication date: August 13, 2020Inventors: Matthew Ryece PROXENOS, Kenneth Stuart PARK, Markus LEHMANN, Gregory VIZIRGIANAKIS, Darlene Elizabeth LUBBE, Debbie Lee LLOYD

Patent number: 10631978Abstract: A prosthetic heart valve (10) which includes a stent (14) having three leaflets (12) attached thereto is provided. The stent (14) is compressible so as to be capable of being introduced into a patient's body through a minimally invasive procedure and has a ring-like body (16) defining in its height three arch-shaped elements (18). Each element (18) includes an arc (20) and a pair of haunches (22) extending from opposite sides thereof, with three commissural posts (26) formed by the haunches (22) of adjacent elements (18). The leaflets (12) each have an attachment edge (28) and a free edge (30) with a belly (32) extending therebetween. The leaflets (12) are movable between a coapted condition, in which the free edges (30) abut and prevent fluid flow through the valve (10), and an open condition, in which fluid flow through the valve (10) is permitted. The leaflets (12) are made from a polymeric material and are moulded directly onto the stent (14) so as to provide for continuous attachment thereof.Type: GrantFiled: April 17, 2014Date of Patent: April 28, 2020Assignee: Strait Access Technologies Holdings (Pty) LtdInventors: Kenneth Stuart Park, Harish Appa, Claude Visagie, Deon Bezuidenhout, Peter Paul Zilla
