Abstract

An implantable prosthetic for connection to a fluid flow pathway of a patient. The prosthetic is comprised of a primary tube structure which is in communication with a plurality of secondary tube structures each of which contains filters for trapping embolic particles, such as blood clots, air bubbles, thrombus. etc. within a fluid flow pathway within a patient. The prosthetic also contains a monitoring device to non-invasively the flow of fluids through a patient'"'"'s fluid flow pathway.

Claims

1. An implantable prosthetic device for connection to the fluid flow pathway of a patient, comprising:

a fluid flow structure having a proximal end, a distal end, a first section, a second section, and a third section, said first section extending from said proximal end to a first position between said proximal end and said distal end, said third section extending from a second position between said first position and said distal end, and said second section extending between said first position and said second position, said first section and said third section only including a single interior lumen, said single interior lumen of said first section having a first cross-sectional area,

wherein said second section includes a plurality of interior lumens, said single interior lumen of said first and third sections being in communication with each of said plurality of interior lumens of said second section, said single interior lumen of said first section being furcated at said first position to form said plurality of interior lumens of said second section, said plurality of interior lumens of said second section combining at said second position to form said single interior lumen of said third section, each of said plurality of interior lumens having a second cross-sectional area, said second cross-sectional area being substantially equivalent to said first cross-sectional area of said single interior lumen of said first section, said plurality of interior lumens of said second section and said single interior lumen of said third section only receiving fluid that flows through said single interior lumen of said first section; and

a filter disposed in each of said plurality of interior lumens of said second section.

2. The implantable prosthetic device of claim 1, wherein said first, second, and third sections of said fluid flow structure have a biocompatible exterior surface.

3. The implantable prosthetic device of claim 1, wherein said first, second, and third sections of said fluid flow structures are formed from polytetrafluoroethylene.

4. The implantable prosthetic device of claim 3, wherein said polytetrafluoroethylene is selected from the group consisting of expanded tetrafluoroethylene, stretched polytetrafluoroethylene, and stretched and expanded polytetrafluoroethylene.

5. The implantable prosthetic device of claim 1, wherein said first, second, and third sections of said fluid flow structures are formed from copolymeric material.

6. The implantable prosthetic device of claim 1, wherein said filter is comprised of a frame and a porous covering coupled to said frame such that said porous covering covers the space defined by said frame.

7. The implantable prosthetic device of claim 6, wherein the pore size of said porous covering is about 20 to about 300 microns.

8. The implantable prosthetic device of claim 6, wherein the said porous covering is a flexible polymeric material comprising regularly-spaced holes therein.

9. The implantable prosthetic device of claim 8, wherein said flexible polymeric material is chosen from the group consisting of polyurethane, polyethylene or a copolymer thereof.

10. The implantable prosthetic device of claim 8, wherein said flexible polymeric material is an elastomeric material capable of stretching to achieve the diameter of a fluid flow pathway.

11. The implantable prosthetic device of claim 1, wherein said filter is removable.

12. An implantable prosthetic device for connection to the fluid flow pathway of a patient, comprising:

a fluid flow structure having a proximal end, a distal end, a first section, a second section, and a third section, said first section extending from said proximal end to a first position between said proximal end and said distal end, said third section extending from a second position between said first position and said distal end, and said second section extending between said first position and said second position, said first section and said third section only including a single interior lumen,

wherein said second section includes a plurality of interior lumens, said single interior lumen of said first and third sections being in communication with each of said plurality of interior lumens of said second section, said single interior lumen of said first section being furcated at said first position to form said plurality of interior lumens of said second section, said plurality of interior lumens of said second section combining at said second position to form said single interior lumen of said third section, each of said plurality of interior lumens having a second cross-sectional area, said second cross-sectional area being substantially equivalent to said first cross-sectional area of said single interior lumen of said first section, said plurality of interior lumens of said second section and said single interior lumen of said third section only receiving fluid that flows through said single interior lumen of said first section, each of said plurality of interior lumens of said second section including at least one fluid flow indicator, said at least one fluid flow indicator operatively connected to indicate a fluid flow when subjected to a pressure created by said fluid flow; and

a filter disposed in each of said plurality of interior lumens of said second section.

13. The implantable prosthetic device of claim 12, wherein said at least one fluid flow indicator is a thin wire filament.

14. The implantable prosthetic device of claim 12, wherein said at least one fluid flow indicator is an impeller.
