1. A method of treating an undesired varicose, reticular or spider vein in a venous system of a patient, the undesired vein having opposing side walls and extending from a proximal end to a distal end, the method comprising the steps of:
substantially emptying the vein of blood between its proximal end and distal end; introducing a medically acceptable adhesive into the substantially emptied vein; and applying pressure to the vein to cause the opposing side walls of the vein to be adhered together in a collapsed configuration by the adhesive, wherein the method further comprises a step of: substantially emptying of blood at least one blood vessel that connects with the undesired vein, prior to the step of introducing the adhesive, such that when the adhesive is introduced the adhesive does not enter into blood vessels that surround said at least one blood vessel that connects with the undesired vein, as there is no blood flow to allow the adhesive to enter into these blood vessels, and wherein in this step blood is emptied from said at least one blood vessel that connects with the undesired vein by compression, using either: (i) an inflatable cuff which is placed over the part of the body containing the at least one blood vessel that connects with the undesired vein and is inflated to apply pressure to said at least one blood vessel, in order to expel blood from the at least one blood vessel, wherein the inflatable cuff includes a non inflatable section which is a cut-out section that is shaped and sized to allow direct access to a section of skin located over the undesired vein, or (ii) a tourniquet that is placed over the part of the body containing the at least one blood vessel connecting with the undesired vein and is used to apply pressure to said least one blood vessel, in order to expel blood from the at least one blood vessel, wherein the tourniquet includes a cut-out window section that is shaped and sized to allow direct access to a section of skin located over the undesired vein, with the cut-out section of the inflatable cuff or the cut-out window section of the tourniquet being sized so as to be locatable over the undesired vein while substantially not covering any major blood vessels connecting with or in the vicinity of the undesired vein, such that the inflatable cuff or tourniquet allows blood to be expelled from said at least one blood vessel connecting with the undesired vein without restricting access to the undesired vein. |
