摘要： Systems and methods for treating thrombosis by driving the drugs or lytic agents through the thrombus by pressure, are disclosed. The system preferably comprises a guide catheter with an occlusion balloon for isolating the region proximal to the thrombus, a guide wire with an occlusion balloon for isolating the region distal to the thrombus and an infusion catheter for delivering drugs or other agents into the region distal to the thrombus under pressure. A lumen of the guide catheter is preferably provided to evacuate material proximal to the thrombus, decreasing the pressure in the proximal to the thrombus. The lumen can be coupled to a thrombus filter to remove thrombolytic material from the drug or lytic agent evacuated from the proximal region. The filtered drug or lytic agent can then be redelivered into the distal region. Recycling of the drug or lytic agent in this manner decreases the costs of the procedure. The systems and methods of the invention can be used to treat other blockages in lumens or vessels in the body or to deliver drugs or other agents to lumens, vessels or cavities within the body, as well.

摘要： A method described includes positioning an x-ray emitter at a treatment area, where the x-ray emitter is connected to a cable, setting a voltage source at a source voltage, and measuring a current through the x-ray emitter. The method may include comparing a current flowing through the emitter with a limit and a low limit. The method further includes increasing the source voltage if the current is higher than the high limit. The method includes determining the high limit and the low limit based on the source voltage and the desired radiation. An apparatus of the invention includes an x-ray emitter with a voltage source and a current sensor. The apparatus may include a current comparison device for comparing the measured current with a high limit and a low limit, and further include a voltage source control. A current integrator for integrating a current from the x-ray emitter may also be included.
