In-situ formation of a valve
First Claim
Patent Images
1. An in-situ forming valve, comprising:
- an expandable component comprising a hollow portion, a distal end, and a proximal end;
a sheet component comprising a distal circumference and a proximal end, the distal circumference held in at least partial contact with the distal end of the expandable component, the proximal end of the sheet component further comprising at least two pinched regions; and
an at least one link attached to at least one point of the proximal end of the sheet, the link attached with the expandable component, the expandable component and link adapted to draw the proximal end of the sheet component into the hollow portion of the expandable component upon expansion of the expandable component, thereby forming a functional valve in situ.

Abstract
The present invention satisfies the long felt need for a more compact and durable valve which may be formed in situ. The present invention provides a self-deployable valve system, a method of delivery, and a method of manufacturing for the self-deployable valve system. The present invention delivers the necessary components for forming a complete valve system in situ. The collapsed subcomponents of the system lack any functional characteristics commonly associated with a valve before being expanded. However, once expanded, the system is transformed into a competent valve for use in a wide variety of applications.

12. An in-situ forming valve, comprising:
-
an expandable component comprising a hollow portion, a distal end, and a proximal end; and a sheet component at least partially enveloping the distal end of the expandable component, the sheet component having a first pre-implantation configuration and a second functional valvular configuration, the first pre-implantation configuration is configured to transform to the second functional valvular configuration; and wherein the expandable component and sheet component are adapted to draw the sheet component into the hollow portion of the expandable component upon expansion of the expandable component and thereby transform the sheet component into the second functional valvular configuration. - View Dependent Claims (13)

14. An in-situ forming valve, comprising:
-
an expandable component comprising a hollow portion, a distal end, and a proximal end; a plurality of prongs pivotally attached with the distal end of the expandable component; and a sheet component comprising a distal end and a proximal end, the proximal end of the sheet component adjustably attached with the each of the plurality of prongs, the prongs adapted to position the proximal end of the sheet component within the hollow portion of the expandable component upon expansion of the expandable component to form a functional valve in situ.

15. An in-situ forming valve, comprising:
-
an expandable component comprising a hollow portion, a distal end, and a proximal end; and a sheet component at least partially attached with the distal end of the expandable component, the sheet component having a first pre-formed configuration and a second functional valvular configuration, the first pre-implantation configuration is configured to transform to the second functional valvular configuration and reversibly transform into the first pre-formed configuration; and wherein the expandable component and sheet component are adapted to draw the sheet component into the hollow portion of the expandable component upon expansion of the expandable component and thereby transform the sheet component into the second functional valvular configuration.
