Abstract
A deployment system is provided. The deployment system includes an expandable stent prosthesis. The expandable stent prothesis includes a trunk portion, a first branching portion attached to the trunk portion, and a second branching portion attached to the trunk portion. The first branching portion is configured to secure the second branching portion when the expanded stent prosthesis is in a collapsed configuration.
Claims20
A deployment system comprising:
- an expandable stent prosthesis comprising:
- a trunk portion;
- a first branching portion attached to the trunk portion;
- and
- a second branching portion attached to the trunk portion;
- wherein the first branching portion is configured to secure the second branching portion when the expanded stent prosthesis is in a collapsed configuration.
3 more elements
A deployment system comprising:
- an expandable stent prosthesis comprising:
- a trunk portion;
- a first branching portion attached to the trunk portion;
- and
- a second branching portion attached to the trunk portion;
- a floss wire extending through the first branching portion and the second branching portion, a distal end of the floss wire extending out of a distal end of the second branching portion;
- wherein an application of a force on the distal end of the floss wire is configured to transition the expandable stent prosthesis from a first collapsed configuration into a second collapsed configuration.
4 more elements
A method of deploying a medical appliance, the method comprising:
- delivering, to a branching implant site comprising a trunk, a first branch, and a second branch, a deployment system via the first branch, the deployment system comprising:
- an expandable stent prosthesis comprising:
- a trunk portion;
- a first branching portion attached to the trunk portion;
- and
- a second branching portion attached to the trunk portion;
- a floss wire extending through the first branching portion and the second branching portion;
- and
- a distal end of the floss wire extending out of a distal end of the second branching portion;
- delivering a distal end of a snare wire to the branching implant site via the second branch;
- connecting the distal end of the floss wire and the distal end of the snare wire together at the branching implant site;
- and
- transitioning the expandable stent prosthesis from a first collapsed configuration in which the first branching portion secures the second branching portion to a second collapsed configuration in which the first branching portion is unsecured from the second branching portion, via displacement of the snare wire.
