A trocar site closure clip includes a generally triangular central body, a pair of arms extending from the body, and an elongated support extending from the body between the arms. In use, the clip is advanced into a patient through a trocar, the trocar removed, then the clip partially retracted to engage and pierce the patient's tissue. The biodegradable clip remains in the patient's tissue, at least partially blocking the trocar site, and degrades over time as the patient heals.

Trocar site closure clip

A trocar site closure clip includes a generally triangular central body, a pair of arms extending from the body, and an elongated support extending from the body between the arms. In use, the clip is advanced into a patient through a trocar, the trocar removed, then the clip partially retracted to engage and pierce the patients tissue. The biodegradable clip remains in the patients tissue, at least partially blocking the trocar site, and degrades over time as the patient heals.

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.
