    摘要: A surgical fastening mechanism for releasably locking an implantable tether includes a housing having a central channel. The housing has an entry aperture, an exit aperture and a side channel extending therebetween. A roller element has a sidewall with an aperture therethrough and the roller is slidably disposed at least partially in the central channel such that the entry and exit apertures are at least partially aligned with the roller aperture. This permits passage of the tether therethrough. Rotation of the roller element in a first direction winds the tether around the roller thereby creating a friction interface between the roller element, the housing and the tether. A locking mechanism is operably connected with either the housing or the roller element and is adapted to prevent rotation of the roller in the central channel and also adapted to prevent release of the tether from the roller.

    摘要: Fastening mechanisms for releasably locking a tether are provided. The mechanisms find application with orthopedic internal-fixation implants and make the implants more reliable and their implantation less invasive. A method for releasably locking a tether comprises advancing the tether through a tether aperture in a clamp body. The tether enters the tether aperture in a first plane and exits in a second plane generally transverse to the first plane. Positioning a fastener element in a fastener aperture in the clamp body captures the tether between the clamp body and the fastener element thereby releasably locking the tether in position relative to the clamp body.
