Abstract:
1. A tissue anchor comprising: a. an elongate tube having a central bore, a closed distal end and a proximal end, wherein said tube has at least first and second apertures angularly spaced about a circumference of the tube; b. an elongate member having a portion sized for receipt and axial movement in said central bore between a first position and a second position, wherein said elongate member includes a longitudinal axis; c. a first anchor member attached to said portion of the elongate member and having a first free distal end carrying a first tissue-penetrating barb; d. a second anchor member attached to said portion of the elongate member and having a second free distal end carrying a second tissue-penetrating barb; and e. wherein said first and second anchor members are configured and positioned so that when said portion of the elongate member is in said first position each of said first and second anchor members is at least partially received in said elongate tube and when said portion of said elongate member is in said second position said first anchor member projects through said first aperture and extends transversely relative to said longitudinal axis with the first free distal end positioned outwardly of the elongate tube at a first angular orientation relative to said elongate tube, and said second anchor member projects through said second aperture and extends transversely relative to said longitudinal axis with the second free distal end positioned outwardly of the elongate tube at a second angular orientation relative to said elongate tube, said first and second angular orientations being circumferentially spaced from one another about said elongate tube.
