Patent number: 11478611Abstract: A catheter delivery system (10) includes: (i) an introducer sheath (12); (ii) a catheter (14) disposed at least partially within the introducer sheath and movable axial along the introducer sheath; (iii) an invaginating tube (16) sealably secured at or near a first axial end (16a) of the invaginating tube to the introducer sheath at or near a first axial end (12 a) of the introducer sheath; (iv) a runner (28) slidably connected to the catheter; (v) the invaginating tube being sealably secured at or near a second axial end (16b) of the invaginating tube to the runner, such that the runner with inavaginating tube secured thereto is sealably connected to the catheter and movable axially along at least a portion of the catheter; and (vi) means for pressurising the annular space defined between the introducer sheath, the catheter and the invaginating tube.Type: GrantFiled: August 28, 2018Date of Patent: October 25, 2022Assignee: Strait Access Technologies Holdings (Pty) LtdInventors: Edward Charles Mudge, Preyen Agasthian Perumall, Deon Bezuidenhout, Peter Paul Zilla, Roman Gottardi

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: 10925736Abstract: A valve leaflet connecting device includes: a base; and first and second followers extending from the base. A first arm extends from the first follower in a direction away from the second follower and away from the base to define an acute angle between the first follower and first arm for capturing a first leaflet there between.Type: GrantFiled: June 10, 2018Date of Patent: February 23, 2021Assignee: Strait Access Technologies Holdings (Pty) LtdInventors: Michael Alan Cousins, Gary Steven Rowsell, Preyen Agasthian Perumall, Jeremy Douglas Jarman, Edward Charles Mudge, Travis Foster Henchie, Heather Madeleine Coombes, Peter Paul Zilla, Deon Bezuidenhout

Patent number: 10779944Abstract: The invention provides a heart valve leaflet capture device (250) comprising a cardiac catheter probe having a proximal end for manipulating the device (250) and a distal end terminating in a transvalve element (256). The transvalve element (256) is configured to pass through a heart valve generally parallel to a longitudinal axis of the catheter and includes two or three leaflet gripping elements (252). The leaflet gripping elements (252) are individually movable by operation of an associated actuating mechanism (260) between a radially retracted position, in which they are withdrawn with respect to the transvalve element (256), and a capture position, in which they diverge outwardly at an acute angle from the transvalve element (256). In the capture position, each leaflet gripping element (252) defines a convergent capture zone that is directed towards the edges of a target valve leaflet and in which the target valve leaflet may be captured.Type: GrantFiled: December 18, 2015Date of Patent: September 22, 2020Assignee: Strait Access Technologies Holdings (Pty) LtdInventors: Michael Alan Cousins, Thomas Gerhardt, Edward Charles Mudge, Jeremy Douglas Jarman, Heather Madeleine Coombes, Peter Paul Zilla, Deon Bezuidenhout

Patent number: 10368852Abstract: An orientation device (200) for use in mitral valve repair surgery is provided and includes a catheter (202) catheter insertable percutaneously through the mitral valve into a chamber of a heart. At least one pressure sensor (216, 218) and two generally arcuate commissural arms (208, 210) are provided at or near the distal end (204) of the catheter (202). The arms (208, 210) are deployable from a stowed condition, in which the catheter (202) can be introduced percutaneously into the heart, to an operative condition in which they extend outwardly in generally opposite directions. Each arm (208, 210) is shaped to be locatable within a mitral valve commissure and has an indentation (212) shaped to extend, in use, at least partially about a mitral valve commissure to limit movement of the device (200) relative to the mitral valve in the axial direction of the catheter (202).Type: GrantFiled: June 26, 2014Date of Patent: August 6, 2019Assignee: STRAIT ACCESS TECHNOLOGIES HOLDINGS (PTY) LTDInventors: Thomas Gerhardt, Michael Alan Cousins, Peter Rudi Haw, Jeremy Douglas Jarman, Edward Charles Mudge, Heather Madeleine Coombes, Deon Bezuidenhout, Peter Paul Zilla
