Claims20
An injection catheter comprising a proximal end, a distal end, at least one injection lumen and at least one exit lumen wherein said injection lumen comprises an injection port through which bioactive material(s) can be delivered to a treatment site and wherein said exit lumen comprises an exit port through which fluids that would otherwise contribute to an increased volume and pressure in the area caused by the injection of said bioactive materials exits the area of the treatment site through said exit port and said exit lumen.
A method of delivering a bioactive material to a treatment site comprising maintaining nearly-constant pressure at said treatment site by using an injection catheter comprising a proximal end, a distal end, at least one injection lumen and at least one exit lumen wherein said injection lumen comprises an injection port through which bioactive material(s) can be delivered to said treatment site and wherein said exit lumen comprises an exit port through which fluids that would otherwise contribute to an increased volume and pressure in the area caused by the injection of said bioactive materials exits the area of the treatment site through said exit port and exit lumen.
