摘要：
Systems and methods are provided for percutaneously suturing tissue. An elongated deployment member having a guide member coaxially disposed over a shaft member may be used to carry a needle deployment member. The needle deployment member may be carried at a distal end of the elongated deployment member and include a plurality of needles releasably secured to the needle deployment member, wherein each needle is routed coaxially within the distal end of the needle deployment member. The needle deployment member may further include a needle pusher driven by a link coaxially disposed within the shaft member, wherein the needle pusher is configured to advance each needle through the distal end of the needle deployment member and coaxially over the proximal end of the needle deployment member to position the plurality of needles at a piercing angle in a proximal direction.
