<p>A device may include a distal assembly (130) including a first plurality of legs (240a), a second plurality of legs (240b), and a distal tip (235), and further include a first driver (260a) and a second driver (260b), a proximal end of at least one leg of the first plurality of legs may be coupled to the first driver, and a proximal end of at least one leg of the second plurality of legs may be coupled to the second driver. The medical device may include a first longitudinally extending hollow member (270a) movably positioned along the first driver and a second longitudinally extending hollow member (270b) movably positioned along the second driver. Movement of the first longitudinally extending hollow member relative to the first driver may converge legs of the first plurality of legs, and movement of the second longitudinally extending hollow member relative to the second driver may converge legs of the second plurality of legs.</p> |
