The invention disclosed herein is a tissue-anchoring system, including a tissue-anchoring device and tissue anchors. The tissue-anchoring device includes a housing and a tissue anchor positioned on the tissue-anchoring device that will be inserted into a tissue or secured onto a tissue. The device may optionally have a plunger assembly slidably positioned in the housing to assist advancing anchor into a tissue. The tissue anchor has a barb end and a shaft. The barb end is adapted to resist removal from a tissue after the anchor has been inserted. The tissue anchor shaft and the barb end may be hollow. The anchor shaft has an attachment member distal from the barb end for direct attachment to a tissue or for attachment of sutures or slings. The tissue anchors may include an adjustment mechanism for intra- or post-operative adjustments.
A tissue anchor system comprising a delivery device and a tissue anchor, said delivery device having a housing, a plunger slidably positioned in said housing, said anchor having a barb end and a barb with a tip shaped to penetrate soft tissue positioned thereon, and an attachment member, said anchor being advanced away from said housing upon operation of said plunger, said barb adapted to resist removal from a tissue once inserted.
An adjustable tissue anchor comprising a housing, said housing having a barb end and a remote end, said housing having an interior having a first interleaving member, and an anchor shaft, said anchor shaft sized to be positioned in said housing, said anchor shaft having a second interleaving member, said first interleaving member and said second interleaving member cooperating, when said anchor shaft is positioned in said interior, to adjustably fix the position of said anchor shaft with respect to said housing, said anchor further having an attachment member.
An adjustable tissue anchor system comprising a delivery device and an anchor, said delivery device having a housing with a hollow barrel portion, said hollow barrel portion having a tip end, said anchor positioned in said hollow barrel portion, said anchor having a barb end with a barb positioned on said barb end and a hollow chamber axially extending therethrough, said hollow chamber having a first interleaving member, said anchor further having a central shaft, said central shaft substantially positioned in said hollow chamber and being moveably positioned through said hollow chamber of said anchor, said central shaft having a tip end, an attachment end, and a second interleaving member, said first and second interleaving members being engageable to resist movement of said central shaft with respect to said hollow chamber.
An adjustable tissue anchor system comprising a delivery device and an anchor, said delivery device having a housing, said housing being adapted to retain said anchor when inserting said anchor into a tissue, said anchor having a hollow chamber axially extending therethrough, said hollow chamber having a barb end, a barb positioned on said barb end, and a first interleaving member, said anchor further having a central shaft substantially positioned in said hollow chamber, and being moveably positioned through said hollow chamber of said anchor, said central shaft having a tip end, an attachment end, and a second interleaving member, said first and second interleaving members being engageable to resist movement of said central shaft with respect to said hollow chamber.
An adjustable tissue anchor comprising:
