1. A dilation catheter device comprising, in combination:
- a shroud tube having a total preselected diameter effective for use in a preselected body lumen, said shroud tube including a means for moving said shroud tube in said lumen;
said shroud tube having a strain relief tube extending therethrough;
said strain relief tube having;
a distal end adapted to reversibly form a flared, funnel-shape and a collapsed shape for contacting the surface of a dilation balloon;
a proximal end terminating in means for moving said strain relief tube;
an internal diameter sufficient to accommodate an elongate flexible balloon catheter;
said balloon catheter extending therethrough;
said balloon catheter having;
a balloon fluid lumen extending therethrough from its proximal to its distal end;
a proximal end terminating in means for moving said balloon catheter;
a balloon mounted on said distal end of said balloon catheter, wherein;
the interior of said balloon is in fluid communication with said balloon fluid lumen;
said balloon is further adapted for inflation into an inflated configuration and deflation into a collapsed configuration;
said balloon has a cross section defining a first cross-sectional area when said balloon is in said inflated configuration and a second cross-sectional area smaller than said first area when said balloon is in-said collapsed configuration; and
, means for connecting said balloon fluid lumen with means for applying pressure and vacuum;
whereby said configuration of said balloon can be altered by altering the position of contact of said distal end of said strain relief tube with said surface of said balloon and by altering said pressure and said vacuum in said balloon fluid lumen.

Abstract
A dilation catheter device comprising a shroud tube having a total preselected diameter effective for use in a preselected body lumen, the shroud tube having a strain relief tube extending therethrough which is adapted to reversibly form a flared, funnel-shape and a collapsed shape for contacting the surface of a dilation balloon, whereby the configuration of the balloon can be altered by altering the position of contact of the distal end of the strain relief tube with the surface of the balloon. Methods for use of the device and articles of manufacture containing the device are also taught.
