| abstract |
Apparatus is provided, including a delivery tool (20) including a handle portion (24) and a shaft (22) slidable with respect to the handle (24). A proximal portion (241) of the shaft (22) is slidable into a lumen (23) of the handle (24). A spool (46) is removably couplable to the delivery tool and is implanted in an intraventricular site (5) of a ventricle. At least one longitudinal member (60, 62) is coupled to the spool (46). A portion of the longitudinal member (60, 62) is configured to be coupled to a first portion of heart tissue (7) that surrounds the ventricular space. The longitudinal member (60, 62) is wound around the spool (46) in response to rotation of the spool (46), and, responsively, draws the second end portion of the longitudinal member and the first portion of heart tissue (7) toward the spool (46). Other applications are also described. |
