Abstract
Abstract This invention is methods and apparatus for occluding blood flow within a blood vessel (22). In a first series of embodiments, the present invention comprises a plurality of embolic devices (16) deployable through the lumen (12) of a conventional catheter (10) such that when deployed, said embolic devices (16) remain resident and occlude blood flow at a specific site within the lumen of the blood vessel (22). Such embolic devices (16) comprise either mechanical embolic devices that become embedded within or compress against the lumen of the vessel or chemical vaso-occlusive agents that seal off blood flow at a given site. A second embodiment of the present invention comprises utilization of a vacuum/cauterizing device capable of sucking in the lumen of the vessel about the device to maintain the vessel in a closed condition where there is then applied a sufficient amount of energy to cause the tissue collapsed about the device to denature into a closure. In a third series of embodiments, the present invention comprises the combination of an embolization facilitator coupled with the application of an energy force to form an intraluminal closure at a specified site within a vessel.

Claim 86
Dependent Claim
60 words
The device of Claim 79 wherein said device further comprises: an inflatable balloon mounted on said probe at a location proximal to said least one suction port and said at least one energy emitting member, said balloon being configured such that when inflated said balloon will substantially occlude the lumen of the blood vessel and will prevent blood flow therethrough.
Claim 87
Independent Claim
136 words
A device for closing the lumen of a blood vessel, said device comprising: an elongate transluminally insertable probe having a detachable core member mounted on the distal end thereof and an energy-transmitting pathway extending longitudinally through the probe, said probe being insertable into the lumen of a blood vessel such that the core member is located at the site at which it is desired to close the blood vessel lumen, energy being subsequently passable through the probe member to cause the blood vessel wall to constrict about and engage the core member, thereby closing the lumen of the blood vessel, said core member being thereafter detachable from said probe member such that the probe member may be extracted and removed from the body leaving the core member implanted within the constricted region of the blood vessel.
Claim 88
Independent Claim
161 words
A device for sealing the lumen of a blood vessel, said device comprising: an elongate catheter having a hollow lumen extending longitudinally therethrough and terminating in a distal opening; an energy-delivering member which is advanceable out of the distal opening of the catheter; said catheter being advanceable through a blood vessel to a location at which the distal end of the catheter is adjacent the site at which the blood vessel is to be closed, a quantity of non-protainaceous, energy-transmitting fluid being infusible through the lumen of the catheter so as to fill the lumen of the blood vessel adjacent the distal end of the catheter, said energy transmitting member being advanceable out of the opening of the catheter and into the energy-transmitting fluid such that energy delivered from the energy delivering member will be transmitted by the energy transmitting fluid to the surrounding wall of the blood vessel, thereby causing the blood vessel to constrict and close at that location.
