Publication number: 20230233323Abstract: An anchor for implantation in body tissue has a number of hooks for engagement with the body tissue. The anchor is made of an elastic material such that it can be elastically deformed into a folded position by application of a constraining force, and will return to an unfolded position when no constraining force is applied. A plugging device is combined with one or more parts of the anchor to provide enhanced contact with the body tissue. The plugging device encircles at least one of the hooks. The anchor may be combined with a line which is a part of the plugging device. The line is optionally joined to the anchor by a knotting configuration having a plurality of loops around the anchor. At least one loop of the plurality of loops encircles at least two of the hooks.Type: ApplicationFiled: May 28, 2021Publication date: July 27, 2023Inventors: Nikolai HIORTH, Hans Emil HIORTH

Publication number: 20220117734Abstract: A catheter device is described. The device is for implanting a leaflet anchor (10) into the heart as part of a procedure for implanting an artificial chordae line (14). The catheter device comprises: a leaflet anchor (10) for attachment to the leaflet (12) of the heart; and a leaflet anchor deployment mechanism (6), (30), (38) for deploying the leaflet anchor (10). The leaflet anchor deployment mechanism (6), (30), (38) allows for retraction and repositioning of the leaflet anchor (10) after deployment of the anchor (10) into the leaflet (12) via an ejector unit (36) having a grasping device (50) with a first configuration arranged to permit deployment of the leaflet anchor (10) into the leaflet (12) without disengagement of the leaflet anchor (10) from the ejector unit (34), and a second configuration in which the leaflet anchor (10) is reversibly released from the ejector unit (36).Type: ApplicationFiled: November 29, 2019Publication date: April 21, 2022Inventors: Nikolai HIORTH, Hans Emil HIORTH

Publication number: 20220023045Abstract: 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.Type: ApplicationFiled: November 29, 2019Publication date: January 27, 2022Inventors: Nikolai HIORTH, Hans Emil HIORTH
