Abstract:
1. A device for simultaneously placing a plurality of suture loops in an ideal pattern across free edge of an opening in a vessel made by percutaneous entry into the body, when the vessel may be calcified, comprising, a. a centerboard in the shape of a flat board having a distal end and a proximal end, and a length therebetween, a width terminating in edges, a thickness between a front face and a back face, and a longitudinal axis being equidistant from the edges and the front face and the back face, and the width being pre-selected to be about one half the circumference of the free edge of the opening in the vessel to be closed, and circumference, the length of the threaded post protruding from the proximal end of the centerboard on the longitudinal axis, and a semi-circular suture cove on the distal end of the centerboard in the shape of a slot between the front face and the back face open on the distal end of the centerboard, b. a plurality of needle openings each having a proximal end and a distal end with a centerline therebetween, each of the centerlines being parallel to the longitudinal axis, and each of the needle openings being open to the front face and the back face of the centerboard and each of the centerlines being located at about a right angle to an approximately straight line across the width of the centerboard just proximal to the suture cove, c. a plurality of needle pairs slidably received within the plurality of needle openings, each having two needles, in two parts, a needle nose and a needle shaft, held together by a temporary connection, wherein the needle shafts are attached to the distal ends of the needle openings and the needle noses point toward the proximal ends of the needle openings and each of the needle noses contains a nose indent, d. a plurality of separator wire channels each having a distal end and a proximal end and a length therebetween, wherein the distal ends of the separator wire channels are open to the plurality of needle openings, e. a plurality of cross slots, located near the proximal end of the centerboard each of the cross slots having a distal end and a proximal end with an opening therebetween being open to the front face and the back face of the centerboard and the distal end of the cross slots being open to the proximal ends of the plurality of separator wire channels, f. a guidewire channel having a proximal end, a distal end and a length therebetween located approximately along the longitudinal axis and having a diameter less than the thickness of the centerboard, and the guidewire channel having a distal port near the distal end of, and open to the back face of the centerboard and a proximal port near the proximal end of, and open to the front face of the centerboard, g. a plurality of separator wires, slidably received within one of the plurality of separator wire channels, and each of the separator wires having a distal end comprising a wedge shape and configured to separate the needle noses when pushed between one of the plurality of a needle pairs, h. a plurality of cross wires slidably received within one of the plurality of in cross slots, and each of the cross wires having two ends and a center point half way between the two ends wherein each of the cross wires is attached at their center point in a right angle to the proximal end of one of the plurality of separator wires, i. a frame for slidably receiving the centerboard therein, the frame having a rectangular box shape and providing finger grips, wherein each of the two ends of the cross wires is attached to the frame, j. a plurality of suture loops stored in the suture cove each of the suture loops having two ends with one of the two ends attached to one of the needle noses of each of the plurality of needle pairs, k. an outboard having a proximal end, a distal end, and a length therebetween, and along the length are two legs attached to a blockhead, each of the legs being of a shape, like a long flat board and like the centerboard but with edges turned in a U-shape toward the other lea wherein the centerboard can slidably be received and the two legs are attached to the blockhead located toward the proximal end of the outboard, and on the distal ends of the legs are foot protuberances having a length, a thickness, and a width, the width being equal to the width of the legs, the thickness being equal to the thickness of the leas and the length extending at a right angle a short distance from the distal ends of the legs making the feet appear turned at a right angle away from the centerboard located between the legs, l. the blockhead having an outside thickness, an outside width and a length, the length extending from the proximal end of the outboard to the outboard legs, the outside thickness being sufficient to overlap the legs, the outside width being about equal to the width of the centerboard near the legs and about equal to the width of the legs near the proximal end of the outboard, and the blockhead has three sets of internal dimensions, the internal dimensions of an unthreaded hole being such as to slidably receive the threaded post and extending from the proximal end of the outboard in the distal direction to a centerboard slot being of dimensions to slidably receive the centerboard and extending distally to a frame slot being of dimensions to slidably receive the frame and extending distally to the legs, m. a plurality of needle nose housings, each being in the shape of a funnel with a narrow end and a wide end, and being of a size for slidably receiving the needle nose and with the narrow end of the funnel in the foot and the wide end of the funnel on the foot at the distal end of the outboard, each of the needle nose housings being located directly opposite one of the needle noses when each of the plurality of needle noses is separated by the wedge ends, and the needle nose housings have housing detents that are located to engage the needle indents, n. a screw turner with the threaded hole in center that self-aligns to engage the threads on the threaded post when the threaded post is in the threaded hole.
