Expandable branching stent prostheses and methods of deployment for the same are discussed herein. An expandable branching stent prosthesis may include a trunk portion, a first branching portion, and a second branching portion that are for deployment at, respectively, a trunk, a first branch, and a second branch of a branching implant site of an anatomical system. Methods for deploying the expandable branching stent prostheses include delivering a deployment system including the expandable branding stent prostheses, a balloon, a distal end of a floss wire, and in some cases a sock to the branching implant site; connecting, to the floss wire, a distal end of a snare wire delivered to the branching implant site via the second branch, and using the two floss wires to manipulate the deployment system to effectuate the deployment. In some cases, the sock may be pulled down over the balloon after the deployment.

Some of the present methods include, and some embodiments of the present systems are configured for gaining access to a patient's vessel by way of the vessel (i.e. from the inside out). Some embodiments facilitate gaining access to an occluded vessel, where part of the access path is through the occlusion.

Devices and methods used to selectively occlude a blood vessel are disclosed. The devices include a catheter having a balloon disposed at a distal end and a connector coupled to a proximal end of the catheter. A handle is coupled to the connector. A slide actuator is disposed within the handle. A seal wire is coupled to the slide actuator. When the slide actuator is in a distal position, the seal wire seals a vent port distal of the balloon to prevent inflation fluid from flowing from the balloon. When the slide actuator is in a proximal position, the seal wire is displaced proximally to unseal the vent port and allow fluid to flow from the balloon and distally out of the vent port resulting in self-deflation of the balloon.

A stent for treating a patient that may comprise a body with a first end portion with a first opening and a second end portion with a second opening opposite the first opening. A stent may include a lumen that extends from the first opening to the second opening. The stent includes a single fenestration disposed in a sidewall of the body between the first opening and the second opening. The single fenestration is disposed in a center portion of the body of the stent in a length direction.
A balloon expandable branching stent prosthesis are discussed herein. The balloon expandable branching stent prosthesis includes a trunk portion including a trunk portion stent frame, a first branching portion including a first branching portion stent frame, a second branching portion including a second branching portion stent frame, and a cover coupling the trunk portion stent frame, the first branching stent frame, and the second branching stent frame together forming a bifurcated stent, wherein the trunk portion stent frame, the first branching portion stent frame, and the second branching portion stent frame are spaced apart from each other with the cover disposed therebetween. A crotch portion of the balloon expandable branching stent prosthesis is disposed between the trunk portion, the first branching portion, and the second branching portion and the crotch portion is reinforced to prevent radial infolding of the cover.
