Abstract
Stent-valves (e.g., single-stent-valves and double-stent-valves), associated methods and systems for their delivery via minimally-invasive surgery, and guide-wire compatible closure devices for sealing access orifices are provided.
Claims20
A stent-valve delivery assembly for cardiac valve replacement, comprising:
- a delivery device including a stent-holder and an outer sheath;
- and
- a stent-valve including a valve component and a stent component housing the valve component, the stent component including at least two attachment elements matably attached to the stent-holder such that the stent-valve is held in position with respect to the delivery device by the stent-holder, wherein the stent-valve has a collapsed configuration for delivery within the outer sheath to an implantation site and a fully expanded configuration after implantation, wherein the stent-valve is configured to be partially expanded while maintaining attachment of the at least two attachment elements to the stent-holder;
- wherein the at least two attachment elements are configured to detach from the stent-holder and cause the stent-valve to expand from the partially expanded configuration to a fully expanded configuration.

A stent-valve delivery assembly for cardiac valve replacement, comprising:
- a delivery device including a stent-holder and an outer sheath;
- and
- a stent-valve including a valve component and a self-expandable stent component housing the valve component, the stent component including at least two attachment elements with geometrical openings removably attached to the stent-holder such that the stent-valve is held in position with respect to the delivery device by the stent-holder, wherein the stent-valve has a collapsed configuration for delivery within the outer sheath to an implantation site and a fully expanded configuration after implantation, wherein the stent-valve is configured to be partially expanded while maintaining attachment of the at least two attachment elements to the stent-holder.
