Apparatus and methods for delivering fasteners during valve replacement |
摘要 |
A fastener delivery tool includes a belt including pairs of features for releasably engaging tines of respective fasteners in a relaxed state defining a loop. The tool includes a loading chamber for receiving a fastener from the belt, a retaining member for limiting movement of the fastener within the loading chamber, an ejection track communicating with the loading chamber, a handle including an actuator, and a tongue and pusher member coupled to the actuator. Activation of the actuator advances the tongue to transform the fastener from the relaxed state to a U-shaped constrained state, and advances the pusher member to direct the fastener from the loading chamber down the ejection track. |
