Abstract
The present invention provides a minimally-invasive percutaneous device that can be positioned within the body of a subject to aid in the movement or pumping of a bodily fluid. In one embodiment, the device comprises a plurality of pump units configured to transform from a first compressed configuration where the pump units are organized in a serial arrangement into a second expanded configuration where the pump units are reorganized into a parallel arrangement.
Claims12
A device for promoting the movement of a bodily fluid comprising:
- at least one pump having:
- a sealed motor connected to an impeller, and
- a housing defining a fluid inlet and outlet;
- and
- a shell having:
- a contiguous and impermeable exterior wall and an interior wall forming a lumen, and one or more anchors positioned on the exterior wall of the shell for displacement from an inner-vessel wall and configured for attachment of the device to a desired implantation site;
- wherein the pump is attached to the shell such that at least a portion of the pump and the fluid outlet is positioned within the lumen of the shell, and wherein the shell is configured to increase a velocity of fluid exiting the shell and generate a venturi effect.
A device for promoting the movement of a bodily fluid comprising:
- at least one pump comprising:
- a sealed motor connected to an impeller, and
- a housing defining a fluid inlet and outlet;
- and
- a shell comprising:
- a contiguous and impermeable wall forming a lumen, and one or more anchors positioned on the exterior wall of the shell for displacement from an inner-vessel wall and configured for attachment of the device to a desired implantation site;
- wherein the pump is positioned within the shell such that at least a portion of the pump and the fluid outlet is positioned within the lumen of the shell.
A device for promoting the movement of a bodily fluid through a target vessel comprising:
- at least one pump comprising:
- a sealed motor connected to an impeller, and
- a housing defining a fluid inlet and outlet;
- and
- a shell comprising:
- a contiguous and impermeable wall forming a lumen, and one or more anchors positioned on the exterior wall of the shell for displacement from an inner-vessel wall and configured for attachment of the device to a desired implantation site;
- wherein the pump is positioned within the shell such that at least a portion of the pump and the fluid outlet is positioned within the lumen of the shell, and wherein an inner diameter of the shell is less than an inner diameter of the target vessel.
