Abstract

An apparatus for delivering bioabsorbable fasteners of the type having two cannulated legs to secure the two sides of an incision in tissue comprises a housing containing a magazine with one or more fasteners positioned on a reciprocally movable fastener support. Needle guide tubes and the legs of the front-most fastener are in slidable contact with at least one alignment surface configured to axially align them. An actuator is operated by a user to move two needles within the needle guide tubes to insert each needle into a cannulated leg. A timing lever acts on the fastener support in concert with the actuator movement to remove support of the front-most fastener after the needles are inserted. The needle guide tubes transfer force to the fastener, to push it out of the magazine and along a path through the center of a bifurcated foot, to insert it into the tissue.

Claims4

Dependent claims

Apparatus for delivering one bioabsorbable fastener from a group of one or more such fasteners, each of the fasteners including a first leg and a second leg, the apparatus comprising:

a first needle and a second needle;
an actuator for use by a user of the apparatus to move the first and second needles;
a first tube and a second tube, the first and second tubes for guiding the movement respectively of the first and second needles when the actuator is used by the user to move the first and second needles;
at least one alignment surface configured to axially align the first and second tubes with the first and second legs respectively;
and
a magazine comprising a fastener support configured to support the bioabsorbable fasteners to guide one of the fasteners at a time into contact with the at least one alignment surface where the moving first and second needles engage with first and second legs respectively to deliver said one fastener, wherein the fastener support moves as a result of the actuator being used by the user to release said one of the fasteners from the magazine.
