Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
124 words
An intravascular method of treating a ruptured artery comprising the steps of locating the area of the rupture, isolating the area of hemorrhage by sealing proximal and distal sites in the area, suctioning clotted blood hemorrhaged from the rupture into the artery through one of the sealed sites, implanting an artificial sleeve in the artery by introducing it intravascularly in a configuration of sufficiently small size to pass freely within the artery from a site remote from the rupture, permanently expanding the sleeve in the artery at the area of the ruptured artery wall, and allowing the expanded sleeve to remain in the artery indefinitely to conduct blood flowing through the artery and prevent loss of such blood flow through the ruptured wall area.
Claim 2
Dependent Claim
124 words
An intravascular method of treating a ruptured artery comprising the steps of locating the area of the rupture, isolating the area of hemorrhage by sealing proximal and distal sites in the area, suctioning clotted blood hemorrhaged from the rupture into the artery through one of the sealed sites, implanting an artificial sleeve in the artery by introducing it intravascularly in a configuration of sufficiently small size to pass freely within the artery from a site remote from the rupture, permanently expanding the sleeve in the artery at the area of the ruptured artery wall, and allowing the expanded sleeve to remain in the artery indefinitely to conduct blood flowing through the artery and prevent loss of such blood flow through the ruptured wall area.
Claim 3
Dependent Claim
23 words
A method as set forth in claim 1, wherein the distal and proximal sites are sealed by expanding intravascularly introduced balloon means therein.
Claim 4
Dependent Claim
26 words
A method as set forth in claim 1, wherein a bypass conduit is temporarily intravascularly introduced to conduct blood flow between opposite sides of said sites.
Claim 5
Dependent Claim
28 words
A method as set forth in claim 1, wherein the sleeve is formed of a material which increases in rigidity after being expanded in place within the artery.
Claim 6
Dependent Claim
35 words
A method as set forth in claim 1, wherein blood clot dissolving agent is injected to the blood mass surrounding the ruptured artery wall prior to and/or during evacuation of blood from the hemorrhaged area.
Claim 7
Dependent Claim
17 words
A method as set forth in claim 5, wherein said blood clot dissolving agent is injected intravascularly.
