Manually separable multi-lumen vascular graft
First Claim
1. An implantable vascular prosthesis comprising plural longitudinally parallel tube structures, each of said tube structures comprising a wall defining a longitudinally extending biocompatible exterior surface and an interior lumen of predetermined diameter for channeling fluid flow therethrough, said parallel tube structures being releasably connected to one another via a thickened wall portion extending over at least a portion of the longitudinal extent of said exterior surfaces to permit manual spatial separation of said tube structures.

Abstract
A vascular prosthesis has a plurality of tubular structures, each of which is manually separable from the others. Each tube structure has a biocompatible exterior surface and a lumen of predetermine diameter. Fluid, such as blood, is channelled through the lumina upon implantation in an arterial or venous pathway. Each of the tube structures is separable from the others over at least a portion of the axial extent of the exterior surface.

- 1. An implantable vascular prosthesis comprising plural longitudinally parallel tube structures, each of said tube structures comprising a wall defining a longitudinally extending biocompatible exterior surface and an interior lumen of predetermined diameter for channeling fluid flow therethrough, said parallel tube structures being releasably connected to one another via a thickened wall portion extending over at least a portion of the longitudinal extent of said exterior surfaces to permit manual spatial separation of said tube structures.
- 6. An implantable vascular prosthesis comprising first and second longitudinally parallel tube structures, each of said structures comprising a wall consisting of polytetrafluoroethylene and defining a longitudinally extending biocompatible exterior surface and an interior lumen of predetermined diameter for channeling blood flow therethrough, said lumina being of unequal diameters and converging to form a single lumen at one end of the vascular prosthesis, said tube structures being releasably connected to one another over at least a portion of the longitudinal extent of said exterior surfaces to permit manual spatial separation of said tube structures.
- 12. An implantable vascular prosthesis comprising plural longitudinally parallel tube structures, each of said tube structures comprising a wall defining a longitudinally extending biocompatible exterior surface and an interior lumen of predetermined diameter for channeling fluid flow therethrough, said parallel tube structures being releasably connected to one another via a bead of material extending over at least a portion of the longitudinal extent of said exterior surfaces to permit manual spatial separation of said tube structures.
- 17. An implantable vascular prosthesis comprising plural longitudinally parallel tube structures, each of said tube structures comprising a wall defining a longitudinally extending biocompatible exterior surface and an interior lumen of predetermined diameter for channeling fluid flow therethrough, said parallel tube structures being releasably connected to one another over at least a portion of the longitudinal extent of said exterior surfaces to permit manual spatial separation of said tube structures wherein the diameter of the lumen of one of the plural tube structures is different from the diameter of the lumen of at least one other of the plural tube structures.
- 21. An implantable vascular prosthesis comprising plural longitudinally parallel tube structures, each of said tube structures comprising a wall defining a longitudinally extending biocompatible exterior surface and an interior lumen of predetermined diameter for channeling fluid flow therethrough, said parallel tube structures being releasably connected to one another over at least a portion of the longitudinal extent of said exterior surfaces to permit manual spatial separation of said tube structures wherein at least two of the lumina converge to form a single lumen at one end of said tube structure.
