Procedural sheath adapter for vascular closure device

Abstract

A tissue puncture closure device includes an anchor, a sealing plug, a compaction member, a suture, a handle portion, a sheath attachment member, and a sheath adapter. The compaction member is configured to compress the sealing plug towards the anchor. The suture is coupled to the sealing plug and anchored. The handle portion is arranged proximal of the sealing plug and anchor. The sheath attachment member extends from the handle portion. The sheath adapter has a first end portion configured to mount to the sheath attachment member, and a second end portion configured to mount to a procedural sheath that is inserted into a tissue puncture.

What is claimed is: 
     
         1 . A tissue puncture closure device, comprising:
 an anchor;   a sealing plug;   a compaction member configured to compress the sealing plug towards the anchor;   a suture coupled to the sealing plug and anchor;   a handle portion arranged proximal of the sealing plug and anchor;   a sheath attachment member extending from the handle portion;   a sheath adapter having a first end portion configured to mount to the sheath attachment member and a second end portion configured to mount to a procedural sheath that is inserted into a tissue puncture.   
     
     
         2 . The device of  claim 1 , wherein the sheath adapter includes a sheath connection portion positioned at the second end portion and a closure device connection portion positioned at the first end portion, the closure device connection portion defining at least one aperture sized to receive the sheath attachment member. 
     
     
         3 . The device of  claim 1 , wherein the second end portion includes at least one flexible arm configured to provide a snap-fit connection with the procedural sheath. 
     
     
         4 . The device of  claim 2 , wherein the closure device connection portion defining first and second apertures sized to receive first and second portions of the sheath attachment member. 
     
     
         5 . The device of  claim 1 , wherein the sheath adapter includes a sheath connection portion positioned at the first end portion and a closure device connection portion positioned at the second end portion, the sheath connection portion including at least one latch member configured to extend into a recess of the procedural sheath. 
     
     
         6 . The device of  claim 1 , wherein the sheath adapter includes a sheath connection portion positioned at the first end portion and a closure device connection portion positioned at the second end portion, the sheath connection portion configured to provide an interference fit with an outer surface of the procedural sheath. 
     
     
         7 . A method of sealing a tissue puncture, comprising:
 providing a procedural sheath, a sheath adapter, and a tissue puncture closure device, the tissue puncture closure device including an anchor, a sealing plug, a suture coupled to the anchor and the sealing plug, and a compaction member;   inserting a distal end portion of the procedural sheath into a tissue puncture;   mounting the sheath adapter to a proximal end portion of the procedural sheath;   mounting the tissue puncture closure device to the sheath adapter.   
     
     
         8 . The method of  claim 7 , wherein mounting the tissue puncture closure device to the sheath adapter includes inserting the anchor and sealing plug of the tissue puncture closure device through the adapter. 
     
     
         9 . The method of  claim 7 , wherein mounting the tissue puncture closure device to the sheath adapter includes inserting at least one closure device connection member of the tissue puncture closure device into a closure device connection aperture of the sheath adapter. 
     
     
         10 . The method of  claim 7 , wherein mounting the tissue puncture closure device to the sheath adapter occurs after mounting the sheath adapter to the procedural sheath. 
     
     
         11 . The method of  claim 7 , wherein mounting the sheath adapter to a proximal end of the procedural sheath includes providing a snap-fit connection between a hub portion of the procedural sheath and a sheath connection member of the sheath adapter. 
     
     
         12 . The method of  claim 7 , wherein mounting the sheath adapter to a proximal end of the procedural sheath includes connecting the sheath adapter to a flushing port of the procedural sheath. 
     
     
         13 . The method of  claim 7 , wherein mounting the sheath adapter to a proximal end of the procedural sheath includes providing an interference fit between the sheath adapter and the procedural sheath. 
     
     
         14 . The method of  claim 7 , wherein the sheath adapter is releaseably mounted to the procedural sheath and the tissue puncture closure device is releaseably mounted to the sheath adapter. 
     
     
         15 . The method of  claim 7 , wherein mounting the tissue puncture closure device to the sheath adapter occurs after positioning the anchor in a vessel that defines the tissue puncture.
