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.

Non-occlusive dilation and deployment catheter device

The invention provides a heart valve leaflet capture device () comprising a cardiac catheter probe having a proximal end for manipulating the device () and a distal end terminating in a transvalve element (). The transvalve element () 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 (). The leaflet gripping elements () are individually movable by operation of an associated actuating mechanism () between a radially retracted position, in which they are withdrawn with respect to the transvalve element (), and a capture position, in which they diverge outwardly at an acute angle from the transvalve element (). In the capture position, each leaflet gripping element () 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.

Heart valve leaflet capture device

An orientation device () for use in mitral valve repair surgery is provided and includes a catheter () catheter insertable percutaneously through the mitral valve into a chamber of a heart. At least one pressure sensor () and two generally arcuate commissural arms () are provided at or near the distal end () of the catheter (). The arms () are deployable from a stowed condition, in which the catheter () can be introduced percutaneously into the heart, to an operative condition in which they extend outwardly in generally opposite directions. Each arm () is shaped to be locatable within a mitral valve commissure and has an indentation () shaped to extend, in use, at least partially about a mitral valve commissure to limit movement of the device () relative to the mitral valve in the axial direction of the catheter ().
