1. An endovascular stapling apparatus for delivering a staple to a vessel of a patient, the apparatus comprising:
- a plurality of clips each including a bridge interconnecting opposing legs, the clips being configured to self-transition to a natural state in which the legs each form a loop from a biased state in which the legs are relatively straight as compared to the natural state;
an elongate housing defining a channel within which the clips are retained in the biased state, the housing forming a deployment window open to the channel; and
a deployment rod slidably disposed within the channel and configured to interface with the clips;
wherein the deployment rod is configured to selectively move at least one of the clips toward and away from the deployment window in response to a corresponding user-applied force such that each of the clips are consecutively releasable from the deployment window with movement of the deployment rod.

Abstract
An endovascular stapling apparatus for delivering a staple to a vessel of a patient, including a plurality of clips, a housing, and a rod. Each of the clips includes a bridge and legs that self-transition from a biased state to a natural state in which the legs each form a loop. The housing defines a channel and a window open to the channel. The clips are retained within the channel in the biased state. The rod is slidably disposed within the channel, selectively moves the clips toward and away from the window, and releases the clips from the window.

17. An endovascular stapling apparatus for delivering a staple to a vessel of a patient, the apparatus comprising:
-
a plurality of clips each including a bridge interconnecting opposing legs, the clips being configured to self-transition to a natural state in which the legs each form a loop from a biased state in which the legs are relatively straight as compared to the natural state; and a delivery instrument comprising; an actuator, a delivery assembly including; a housing forming a channel and a deployment window open to the channel, a deployment rod slidably disposed within the channel, the deployment rod including a proximal region connected to the actuator, wherein the channel is sized to constrain the clips to the biased state and the deployment rod is configured to interface with the clips; a catheter forming a lumen within which at least a portion of the housing is disposed, an introducer extending distal the housing; and a guide wire slidably associated with the instrument; wherein in an initial, loaded state of the apparatus, the actuator is operable to repeatedly move the deployment rod relative to the housing in partially deploying, withdrawing, and fully deploying each of the clips from the deployment window.

18. A method of delivering a staple through a bodily lumen, the method comprising:
-
providing an endovascular stapling apparatus including; a plurality of clips each including a bridge interconnecting opposing legs, the clips being configured to self-transition from a biased state in which the legs are relatively straight to a natural state in which the legs each form a loop, a delivery assembly including; a housing defining a channel within which the clips are retained in the biased state, and forming a deployment window open to the channel, a deployment rod slidably disposed within the channel and configured to interface with the clips, a catheter forming a lumen within which the housing is at least partially disposed; delivering the delivery assembly into the bodily lumen; positioning the deployment window at a target site of the bodily lumen; proximally retracting the deployment rod relative to the housing to deploy a portion of a first clip from the deployment window; evaluating a position of the partially deployed first clip relative to the bodily lumen; distally advancing the deployment rod relative to the housing to at least partially withdraw the portion of the first clip back into the housing; repositioning the delivery assembly relative to the bodily lumen; and proximally retracting the deployment rod relative to the housing to fully deploy the first clip through the deployment window. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
