Abstract

Surgical instruments, guides, and methods for closure of fascia and other tissue sites are disclosed. A suture passer guide comprises an elongate body with first and second passages for guiding a suture passer. The long axes of the elongate body, the first passage, and the second passage, preferably lie in three separate parallel planes. A suture passer comprises a housing having a needle tip portion and a first suture grasping surface. An elongate body is located at least partially within the housing and is configured to slide within the housing. The elongate body has a second suture grasping surface at the distal end. The first and second suture grasping surfaces preferably are spaced from the needle tip portion.
