Local Biomechanical and/or Antimicrobial Ligation Device

Abstract

A ligation device is disclosed that is capable of containing a fluid, e.g., a biomechanical medium or an antimicrobial solution. The ligation device comprises an upper clip and a lower clip, each having a locking feature that enables the upper clip and the lower clip to be movably attached to each other.

1 - 11 . (canceled) 
     
     
         12 . A surgical fastener comprising:
 a fastener member having a backspan and at least two prongs generally perpendicular to the backspan; and   a retainer portion having a connector and at least two members attached to the connector, each member having an aperture to receive and to retain the prongs, the retainer portion defining a reservoir configured to store a fluid therein, wherein the fastener member is releasably secured to the retainer portion, the connector being flexible and allowing movement of the at least two members toward and away from each other.   
     
     
         13 . A surgical fastener comprising:
 a fastener member having a backspan and legs generally perpendicular to the backspan with at least one leg housing a reservoir; and   a retainer portion with a connector and at least two columnar members attached to the connector, each columnar member having an aperture to receive and retain the legs, a cutting feature extending from at least one of the at least two columnar members.   
     
     
         14 . The surgical fastener of  claim 12  further comprising: a locking surface extending from at least one prong that is removably attached to a locking surface extending from at least one aperture. 
     
     
         15 . The surgical fastener of  claim 12  further comprising a membrane seal at an opening of the aperture. 
     
     
         16 . The surgical fastener of  claim 13  further comprising a membrane seal at an opening of the reservoir. 
     
     
         17 . The surgical fastener of  claim 12 , wherein the prongs have a sharp distal tip. 
     
     
         18 . The surgical fastener of  claim 12 , wherein the fluid is either an antimicrobial solution or a biomechanical medium. 
     
     
         19 . The surgical fastener of  claim 12 , further comprising a groove located on the inner surface of the retainer portion. 
     
     
         20 . The surgical fastener of  claim 14 , wherein each prong defines a distal end that is disposed within the respective member of the retainer portion when the fastener member is releasably secured to the retainer portion. 
     
     
         21 . The surgical fastener of  claim 12 , wherein at least one of the at least two prongs includes a groove and the retainer portion includes a protrusion configured to releasably engage the groove. 
     
     
         22 . The surgical fastener of  claim 21 , wherein the fastener member is separable from the retainer portion when the groove is separated from the protrusion of the retainer portion. 
     
     
         23 . The surgical fastener of  claim 12 , wherein the retainer portion defines a gap between the at least two members. 
     
     
         24 . The surgical fastener of  claim 12 , wherein the fastener member is removable from the retainer portion by moving the at least two prongs toward one another.
