Abstract
Abstract A distensible artificial tubular graft structure is provided that has a compliance gradient. The graft may be used to repair a patient's body organ tubing. For example, the graft may be used to replace or supplement portions of a patient's vascular system. The ends of the graft structure may have compliances that are matched to the compliances of the body organ tubing to which they are attached. Distensible compliance-matched connector structures may be used to attach the graft to the body organ tubing.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
82 words
A graft for installation in the body of a patient between portions of body organ tubing with different compliances, comprising a distensible artificial tubular graft structure with a substantially smooth compliance gradient along the length of the artificial tubular graft structure, wherein the distensible artificial tubular graft structure comprises a tubular elastic structure having pores, wherein the compliance of the distensible artificial tubular graft structure is determined at least in part by the quantity of the pores in the tubular elastic structure.
Claim 2
Dependent Claim
82 words
A graft for installation in the body of a patient between portions of body organ tubing with different compliances, comprising a distensible artificial tubular graft structure with a substantially smooth compliance gradient along the length of the artificial tubular graft structure, wherein the distensible artificial tubular graft structure comprises a tubular elastic structure having pores, wherein the compliance of the distensible artificial tubular graft structure is determined at least in part by the quantity of the pores in the tubular elastic structure.
Claim 3
Dependent Claim
85 words
A graft for installation in the body of a patient between portions of body organ tubing with different compliances, comprising a distensible artificial tubular graft structure with a substantially smooth compliance gradient along the length of the artificial tubular graft structure, wherein the distensible artificial tubular graft structure comprises a tubular elastic structure having pores, wherein the compliance of the distensible artificial tubular graft structure is determined at least in part by the size and the quantity of the pores in the tubular elastic structure.
Claim 4
Dependent Claim
85 words
A graft for installation in the body of a patient between portions of body organ tubing with different compliances, comprising a distensible artificial tubular graft structure with a substantially smooth compliance gradient along the length of the artificial tubular graft structure, wherein the distensible artificial tubular graft structure comprises a tubular elastic structure having pores, wherein the compliance of the distensible artificial tubular graft structure is determined at least in part by the size and the quantity of the pores in the tubular elastic structure.
