Patent number: 9119719Abstract: A method includes positioning an anchor deployment manipulator at least partially within a lumen of a sleeve of an annuloplasty ring, the sleeve having a lateral wall shaped to define the lumen, and the lumen extending longitudinally along a length of the sleeve. A portion of the sleeve that contains a distal end of the deployment manipulator is placed into an atrium in a vicinity of an annulus of an atrioventricular valve. An anchor is deployed from the distal end of the deployment manipulator through the lateral wall of the sleeve into cardiac tissue, while the distal end of the deployment manipulator is positioned such that a central longitudinal axis of the deployment manipulator through the distal end of the deployment manipulator forms an angle of between 45 and 90 degrees with the lateral wall of the sleeve at a point at which the anchor penetrates the lateral wall.Type: GrantFiled: January 24, 2013Date of Patent: September 1, 2015Assignee: VALTECH CARDIO, LTD.Inventors: Yuval Zipory, Oz Cabiri, Yossi Gross

Patent number: 9066719Abstract: Some embodiments relate to a device for delivering shape-memory staples. The device comprises a grippable portion comprising a first actuator; and a delivery portion coupled to the grippable portion. The delivery portion comprises retention walls for retaining the staples within the delivery portion in an elastically deformed configuration and release apertures for releasing the staples to adopt a deployed configuration based on their shape memory. The delivery portion is configured to cause one end of each staple to protrude from the delivery portion in response to actuation of the first actuator. In some embodiments a striking mechanism is coupled to the grippable portion and configured to communicate a striking blow to the delivery portion.Type: GrantFiled: March 11, 2010Date of Patent: June 30, 2015Assignee: ENDOGENE LIMITEDInventors: Mikhail Soutorine, Artem Nicolaevich Chernov-Haraev
