Abstract
Described are devices, methods, and systems useful for deploying one or more occlusive prostheses within the vasculature of a patient. Illustrative devices can include a deployment tube or sheath that contains an occlusive prosthesis, wherein a segment of the sheath is reversible by a user so as to deploy the prosthesis from the sheath lumen within a bodily lumen of a patient.
Claims24
A medical product for the delivery of a prosthesis within the vasculature of a patient, comprising:
- a sponge form prosthesis, said sponge form prosthesis having a proximal end and a distal end, wherein said sponge form prosthesis is movable between a constrained position and an expanded position;
- and
- a cannulated device, said cannulated device having a proximal end, a distal end, a lumen, and a reversible segment, wherein the reversible segment contains the sponge form prosthesis and is reversible by a user so as to deploy the sponge form prosthesis within the vasculature of a patient;
- wherein said sponge form prosthesis is expansible at least 100% by volume when wetted to saturation with deionized water.
1 more element
An endoluminal medical product, comprising:
- a percutaneous deployment sheath having a proximal end, a distal end, and a wall that defines a lumen;
- a sleeve having a proximal end, a distal end, and a lumen, wherein said sleeve is slidably received within said sheath lumen and said sleeve distal end extends from and reverses over said sheath distal end and wherein said sleeve is configured to deploy at least one bioremodelable prosthesis from a constrained position within said sleeve lumen to an expanded position within a patient's vasculature by reversing said sleeve around said distal end of said sheath;
- wherein said bioremodelable prosthesis is configured to radially expand from said constrained position to said expanded position sufficiently to contact outer surfaces of the bioremodelable prosthesis with a wall of the patient's vasculature;
- wherein the bioremodelable prosthesis comprises an occlusion device;
- wherein the occlusion device comprises a sponge form material;
- and
- wherein the sponge form material is expansible at least 100% by volume when wetted to saturation with deionized water.
