Abstract

Methods for modifying a balloon of a catheter assembly are disclosed.

Claims

1. -20. (canceled)

21. A method of modifying a balloon of a catheter assembly, comprising:

inflating and/or deflating the balloon; and

while the balloon is being inflated and/or deflated, applying a substance on a surface of the balloon.

22. The method of claim 21, wherein the inflating and/or deflating step includes inflating and/or deflating the balloon so that the balloon assumes at least one of a hyper-inflated, intended expanded configuration and under-inflated state.

23. The method of claim 21, wherein the applying step includes depositing the substance within the balloon'"'"'s wall membrane, wherein the balloon'"'"'s wall membrane is enclosed at one end of the catheter assembly such that the enclosed wall membrane allows the balloon to inflate and deflate on the catheter assembly.

24. The method of claim 23, wherein the wall membrane is made from a porous material.

25. The method of claim 23, wherein the wall membrane is made from a non-porous material having pores formed thereon.

26. The method of claim 21, wherein the inflating and/or deflating the balloon step includes pulsating the balloon to a greater and/or smaller diameter, respectively.

27. The method of claim 21, wherein the inflating and/or deflating the balloon step includes monotonically increasing and/or decreasing the balloon pressure.

28. The method of claim 21, wherein the substance is inflated and deflated during the applying step.

29. A method of modifying a balloon of a catheter assembly, comprising:

inflating and/or deflating the balloon; and

while the balloon is being inflated and/or deflated, removing a fluid carrier for a substance disposed on the balloon surface.

30. The method of claim 29, further including the step of reducing the balloon to a deflated or collapsed configuration prior to or during a removing the fluid carrier from the balloon step.

31. The method of claim 29, further including the step of inflating the balloon to a greater extent prior to or during a removing the fluid carrier from the balloon step.

32. The method of claim 29, wherein the balloon is pulsed to a greater and/or smaller size during the removal of the fluid carrier.

33. The method of claim 29, wherein the balloon is inflated and deflated during the removing step.
