An anchor (10) for implantation in body tissue (12) to hold a line (14) comprises: an elastic material formed to have an unfolded configuration for placement within the body tissue (12), and a folded configuration for use prior to deployment of the anchor (10) and arranged to permit placement of the anchor (10) into an anchor tube (38) prior to deployment. The anchor (10) is arranged to be elastically deformed into the folded configuration by application of a constraining force, and will return to the unfolded configuration when no constraining force is applied. When the anchor (10) is in the unfolded configuration the anchor (10) has an elongate configuration comprising two anchor pins (82) extending in opposite directions with one either side of a centre (80) of the anchor (10), whilst when the anchor (10) is in the folded configuration the two pins (82) both extend in the same direction; and wherein ends (84) of the pins (82) are arranged to pierce the body tissue.
An anchor for implantation in body tissue to hold a line, the anchor comprising:
An anchor as claimed in any preceding claim, comprising openings through the material of the pins.
A catheter device comprising an anchor deployment mechanism and an anchor as claimed in any preceding claim.
A catheter device as claimed in any of claims 14 to 19, comprising a groove in a wall of the leaflet anchor tube for guiding the ejector unit via a guide pin on the ejector unit;
A catheter device as claimed in 19, wherein the narrowing is provided in order to signify that the anchor has been moved to the deployed position, whilst the ejector unit remains in the first configuration, and to inform the user that once the ejector unit is pushed further then the ejector unit will move to the second configuration.
