Abstract
A suture retriever and method for manipulating suture during endoscopic surgical procedures. The suture retriever has an elongated housing provided with a needle tip and a lateral opening situated near the tip. A suture engaging hook is extendable through the lateral opening and away from the axis of the housing in order to snare a suture. The hook is situated at the distal end of an elongated flexible support which is pre-formed in order to enable the hook to be laterally displaced from the axis of the needle tip when the support is moved distally relative to the lateral opening. When a suture is engaged by the hook, the latter is retracted proximally in order to place and hold the suture adjacent the lateral opening.
