Trocar site closure assembly

摘要

Embodiments of this invention relate to trocar site closures including a head with a plurality of arm receiving passages therethrough, an arm received by each of the passages, each passage having a discontinuity which allows each arm to be pulled inward but deters outward movement, and each arm having a grappling portion. The head and arms are inserted into a patient wound, such as a trocar site. The arms engage with tissue surrounding the wound. A pulling force is exerted on the arm proximal ends, drawing the distal ends of the arms toward the head and at least partially closing the wound. The head and at least a portion of the arms remain in the patient, and are preferably made of a biocompatible material. Embodiments of this invention also relate to an insertion device used to insert the closure into the wound and at least partially close the wound.

主权项

1. A trocar site closure system, comprising:
a trocar site closure including: a. a head, said head having a plurality of arm receiving passages therethrough, each of said plurality of arm receiving passages having a discontinuity therein; b. a plurality of arms, each of said plurality of arms having a distal end and an opposed proximal end, each said arm having a grappling portion; c. each of said plurality of arms is received by one of said plurality of arm receiving passages, and where said discontinuity in each said arm receiving passage permits movement of said arm received when said arm is pulled from said proximal end, but where said discontinuity in each said arm receiving passage deters movement of said arm received when said arm is pulled from said distal end; wherein each said arm receiving passage is from an exterior opening in said head to an interior opening in said head and where said arm received in said arm receiving passage has a portion terminating in said distal end extending from said exterior opening and a portion terminating in said proximal end extending from said interior opening; and wherein each said discontinuity is a ramp, said ramp sloping upward from a location toward said exterior opening in said head to a location toward said interior opening in said head.
