A tissue stabilizer for endoscopically stabilizing a target tissue within a patient's body, the tissue stabilizer comprising: a shaft sized to allow insertion through an endoscopic cannula; and a manipulatable foot connected with the shaft, wherein the manipulatable foot comprises a first toe portion and a second toe portion, the first and second toe portions (1042, 1046) being rotatably coupled with the shaft by an adjustable ankle, the adjustable ankle providing that at least one of the first and second toe portions (1042, 1046) are rotatable with respect to the shaft, the tissue stabilizer characterised in that: the manipulatable foot further comprises a first angular strut and a second angular strut, the first angular strut coupled at a proximal end to the adjustable ankle and coupled at a distal end to the first toe portion, the second angular strut coupled at a proximal end to the adjustable ankle and coupled at a distal end to the second toe portion; wherein the first toe portion is spaced apart from, and substantially parallel to, the second toe portion when the first angular strut and the second angular strut are pivoted about the ankle in a deployed position; and wherein the first toe portion lies overlapping at least a portion of the second toe portion when the first angular strut and the second angular strut are pivoted about the ankle in a furled position. a shaft sized to allow insertion through an endoscopic cannula; and a manipulatable foot connected with the shaft, wherein the manipulatable foot comprises a first toe portion and a second toe portion, the first and second toe portions (1042, 1046) being rotatably coupled with the shaft by an adjustable ankle, the adjustable ankle providing that at least one of the first and second toe portions (1042, 1046) are rotatable with respect to the shaft, the tissue stabilizer characterised in that: the manipulatable foot further comprises a first angular strut and a second angular strut, the first angular strut coupled at a proximal end to the adjustable ankle and coupled at a distal end to the first toe portion, the second angular strut coupled at a proximal end to the adjustable ankle and coupled at a distal end to the second toe portion; wherein the first toe portion is spaced apart from, and substantially parallel to, the second toe portion when the first angular strut and the second angular strut are pivoted about the ankle in a deployed position; and wherein the first toe portion lies overlapping at least a portion of the second toe portion when the first angular strut and the second angular strut are pivoted about the ankle in a furled position. the manipulatable foot further comprises a first angular strut and a second angular strut, the first angular strut coupled at a proximal end to the adjustable ankle and coupled at a distal end to the first toe portion, the second angular strut coupled at a proximal end to the adjustable ankle and coupled at a distal end to the second toe portion; wherein the first toe portion is spaced apart from, and substantially parallel to, the second toe portion when the first angular strut and the second angular strut are pivoted about the ankle in a deployed position; and wherein the first toe portion lies overlapping at least a portion of the second toe portion when the first angular strut and the second angular strut are pivoted about the ankle in a furled position.
