of the trunk shown in the embodiment 80 in fig7 as 82 the braiding is then stopped and the wires are taped or clamped to the mandrel the wires leading to the spools are cut and the mandrel assembly and braided device are removed from the braider the finished device 80 has a trunk portion braided from single filaments or wires as is shown in fig7 in the embodiment with the loop braid the final braiding of the trunk may be accomplished on the same original 32 carrier braider used for braiding the legs but four of the spools i e every 8th spool would be empty however this would cause the final device to exhibit gaps between some of the braided wires this is not as desirable as using a braider with the exact number of needed spool carriers the gaps can be manually spaced more evenly prior to the final device heat treatment to be discussed in the following braiders are available in a wide variety of spool carrier numbers such as 4 200 or more in increments of four carriers as offered for example by steeger usa spartanburg s c the heat treatment process follows the braiding of the device in the case where the braiding process was accomplished on a mandrel that equals the final device size the braid may remain on the mandrel if the mandrel was made of metal or a material able to adequately handle the temperature of the device heat treatment heat treatment techniques are generally known to those skilled in the art u s pat no 5 725 552 to kotula et al incorporated herein in entirety by reference for example describes in great detail the heat treatment of braided medical devices made of nitinol wire and the.
