The device may also include a carrier defining a pusher thereon. The carrier may be configured to transition between a first state and a second state. In the first state, a distal portion of the carrier may extend within the working channel along a central longitudinal axis thereof. In the second state, the distal portion of the carrier may extend distally of the luminal body. The device may also include a plurality of anchors which may be disposed about the carrier. Also, at least a distal-most anchor of the plurality of anchors may define a surface configured to cooperate with the pusher and further defines a curved wall configured to cooperate with the pusher to rotate the plurality of anchors. ## Claims ### Claim 1 A medical device, comprising: a luminal body defining a working channel extending between a proximal end of the luminal body and a distal end of the luminal body; a carrier defining a pusher thereon, wherein the carrier is configured to transition between a first state and a second state, wherein in the first state, a distal portion of the carrier extends within the working channel along a central longitudinal axis thereof, and wherein in the second state, the distal portion of the carrier extends distally of the luminal body; and a plurality of anchors, each anchor of the plurality of anchors disposed about the carrier, wherein at least a distal-most anchor of the plurality of anchors defines a surface configured to cooperate with the pusher, and wherein at least the distal-most anchor of the plurality of anchors further defines a curved wall configured to cooperate with the pusher to rotate the plurality of anchors. ### Claim 2 (depends on 1) The medical device of claim 1, wherein the carrier is comprised of a shape memory material. ### Claim 3 (depends on 1) The medical device of claim 1, wherein the carrier has a distal tip configured to pierce tissue. ### Claim 4 (depends on 3) The medical device of claim 3, wherein the distal tip of the carrier is configured to be passed through a central lumen of each of the plurality of anchors. ### Claim 5 (depends on 1) The medical device of claim 1, wherein the plurality of anchors comprises at least the distal most anchor and a travel anchor, wherein the travel anchor is coupled to the distal most anchor via at least one suture member. ### Claim 6 (depends on 1) The medical device of claim 1, wherein each anchor of the plurality of anchors defines a recess configured to cooperate with the pusher, and wherein each anchor of the plurality of anchors defines a curved wall configured to cooperate with the pusher to rotate the plurality of anchors. ### Claim 7 (depends on 6) The medical device of claim 6, wherein each anchor of the plurality of anchors is coupled to an adjacent anchor of the plurality of anchors via at least one suture member. ### Claim 8 (depends on 1) The medical device of claim 1, further comprising: a handle coupled to the proximal end of the luminal body and including an actuator operably coupled with the carrier to move the carrier between the first and second states. ### Claim 9 (depends on 8) The medical device of claim 8, wherein the actuator is operably coupled to the carrier via a cam follower mechanism. ### Claim 10 (depends on 1) The medical device of claim 1, wherein each anchor of the plurality of anchors define a proximal extension and a distal recess. ### Claim 11 (depends on 10) The medical device of claim 10, wherein the proximal extension of each anchor of the plurality of anchors is configured to be matingly received within the distal recess of an adjacent anchor of the plurality of anchors. ### Claim 12 (depends on 10) The medical device of claim 10, wherein the proximal extension and distal recess of at least some of the plurality of anchors are radially offset from one another while the proximal extension and distal recess of the remaining anchors of the plurality of anchors are aligned along a common axis. ### Claim 13 A method of joining tissue, comprising: advancing a carrier distally of a working channel of a medical device comprising a luminal body defining the working channel so as to cause the carrier to transition between a first state and a second state, wherein in the first state, a distal portion of the carrier extends within the working channel along a central longitudinal axis thereof, and wherein in the second state, the distal portion of the carrier extends distally of the working channel; and positioning at least one anchor of a plurality of anchors adjacent tissue to be joined, wherein each anchor of the plurality of anchors is disposed about the carrier, wherein at least a distal-most anchor of the plurality of anchors defines a surface configured to cooperate with a pusher on an external surface of the carrier, and wherein at least a distal-most anchor of the plurality of anchors further defines a curved wall configured to cooperate with the pusher to rotate the plurality of anchors. ### Claim 14 (depends on 13) The method of claim 13, wherein positioning the at least one anchor of the plurality of anchors includes engaging the pusher with the surface so as to distally advance the at least one anchor while advancing the carrier. ### Claim 15 (depends on 13) The method of claim 13, wherein advancing the carrier includes actuating a cam follower mechanism. ### Claim 16 (depends on 13) The method of claim 13, wherein the carrier is comprised of a shape memory material. ### Claim 17 (depends on 13) The method of claim 13, wherein each anchor of the plurality of anchors is coupled to an adjacent anchor of the plurality of anchors via at least one suture member. ### Claim 18 A medical device, comprising: a luminal body defining a working channel extending between a proximal end of the luminal body and a distal end of the luminal body;
