Abstract
The present disclosure relates to the field of body lumen drainage. Specifically, the present disclosure relates to implantable medical devices for facilitating the flow of fluids and materials between adjacent body lumens. In particular, the present disclosure relates to a drainage stent which maintains an open flow passage between fused tissue layers.
Claims20
A drainage system, comprising:
- an elongate tubular body having first and second opposing ends, the elongate tubular body comprising a first retention structure at the first end of the body and a cylindrical saddle region extending between the first retention structure and the second end of the body;
- and
- a funnel member configured to form an interference fit with the first retention structure,
- wherein:
- the funnel member is configured to move between a deployed configuration and a delivery configuration;
- in the delivery configuration, the funnel member is foldable towards the second end of the body along an outer surface of the first retention structure;
- and
- in the deployed configuration, the funnel member and elongate tubular body define an open central lumen providing a flow path therethrough.

A stent system, comprising:
- a stent having first and second opposing ends, the stent comprising a first retention structure at the first end of the stent and a saddle region extending between the first retention structure and the second end of the stent;
- and
- a funnel member configured to form an interference fit with the first retention structure,
- wherein:
- the funnel member is configured to move between a deployed configuration and a delivery configuration;
- when the funnel member is in the delivery configuration, the funnel member is foldable towards the second end of the stent along an outer surface of the first retention structure;
- when the funnel member is in the deployed configuration, the funnel member and the stent define an open flow path therethrough.
4 more elements
A delivery system, comprising:
- a conduit comprising an elongate tubular body including first and second retention structures, a cylindrical saddle region extending therebetween, and a funnel member configured to form an interference fit with the first retention structure,
- wherein:
- the funnel member and conduit are configured to move between a deployed configuration and a delivery configuration;
- in the delivery configuration, the funnel member is foldable towards the second end of the elongate tubular body along an outer surface of the first retention structure;
- and
- in the deployed configuration, the funnel member and elongate tubular body define a central lumen to provide a flow path therethrough;
- and
- a delivery device configured to carry the conduit and funnel member in the delivery configuration.
