Abstract
Abstract Internal prosthesis for the substitution of a part of the human body particularly in vascular surgery, which has a body (2) with a substantially tubular configuration made of plastic material tolerated by the human body and suitable for being associated by its free ends through a suture, to the ends of one or more arteries: advantageously the body defining prosthesis is radiopaque (4) so that it can be easily detected by means of an X-ray apparatus.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
87 words
A prosthetic device for vascular surgery, comprising a substantially tubular body including plastic material and tolerated by the human body, wherein said tubular body has free ends for attaching to at least one artery, and wherein said tubular body has radiopaque annular portions which are continuous over the entire surface of said tubular body and spaced equidistant along said tubular body for detection of said tubular body by X-rays wherein the radiopaque annular portions do not alter the functional properties or special nature of the prosthetic device.
Claim 2
Dependent Claim
87 words
A prosthetic device for vascular surgery, comprising a substantially tubular body including plastic material and tolerated by the human body, wherein said tubular body has free ends for attaching to at least one artery, and wherein said tubular body has radiopaque annular portions which are continuous over the entire surface of said tubular body and spaced equidistant along said tubular body for detection of said tubular body by X-rays wherein the radiopaque annular portions do not alter the functional properties or special nature of the prosthetic device.
Claim 3
Dependent Claim
15 words
The device of claim 1 wherein said radiopaque annular portions are integral to said body.
Claim 4
Dependent Claim
13 words
The device of claim 1 wherein said radiopaque annular portions comprise a filament.
Claim 5
Dependent Claim
13 words
The device of claim 1 wherein said radiopaque annular portions comprise a fabric.
Claim 6
Dependent Claim
12 words
The device of claim 4 wherein said radiopaque annular portions are visible.
Claim 7
Dependent Claim
16 words
The device of claim 5 wherein each of said radiopaque annular portions has a different stain.
Claim 8
Dependent Claim
89 words
A prosthetic device for vascular surgery, comprising a substantially tubular body including plastic material and tolerated by the human body, wherein said tubular body has free ends for attaching to at least one artery, and wherein said tubular body has radiopaque similar portions integral to said body wherein said radiopaque portions are visible and continuous over the entire surface of said tubular body and spaced equidistant along said tubular body for detection of said tubular body by X-rays and wherein each of said radiopaque portions has a different stain.
Claim 9
Dependent Claim
89 words
A prosthetic device for vascular surgery, comprising a substantially tubular body including plastic material and tolerated by the human body, wherein said tubular body has free ends for attaching to at least one artery, and wherein said tubular body has radiopaque similar portions integral to said body wherein said radiopaque portions are visible and continuous over the entire surface of said tubular body and spaced equidistant along said tubular body for detection of said tubular body by X-rays and wherein each of said radiopaque portions has a different stain.
Claim 10
Dependent Claim
26 words
The device of claim 7 wherein said body has a stain and said stain of said body is different from said stains of said radiopaque portions.
