First Claim
1. An apparatus adapted for insertion in a body lumen having a surgical connection, the apparatus comprising:
- a first conduit insertable in the lumen, the first conduit having a distal end portion for being positioned spaced distally beyond the surgical connection, the first conduit directing fluid through the lumen and isolating the fluid from the surgical connection;
a second conduit insertable in the lumen, the second conduit having a distal end portion positioned adjacent the surgical connection, the second conduit being adapted to control the pressure in a space in which the surgical connection is exposed.

Abstract
An apparatus (50) is adapted for insertion in a body lumen (140) having a surgical connection (58). The apparatus (50) includes a first conduit (80) insertable in the lumen (140) and having a distal end portion spaced distally beyond the surgical connection (58). The first conduit (80) directs fluid through the lumen (140) and isolates the fluid from the surgical connection (58). The apparatus (50) also includes a second conduit (84) insertable in the lumen (140). The second conduit (84) has a distal end portion positioned adjacent the surgical connection (58). The second conduit (84) is adapted to control the pressure in a space (90) in which the surgical connection (58) is exposed.

15. A catheter system comprising:
-
a Foley catheter insertable through a urethra into a bladder, the Foley catheter having a proximal end portion for being positioned outside the urethra and an opposite distal end portion for being disposed in the bladder, the Foley catheter comprising a first conduit for emptying the bladder, an elastic bulb disposed on the distal end portion in the bladder, and a second conduit for delivering inflation fluid to the elastic bulb, the elastic bulb being inflatable to help retain the Foley catheter inserted in the bladder; and
a concentric tubular member encircling the Foley catheter, the tubular member having a proximal end portion positioned outside urethra and an opposite distal end portion that terminates before a proximal end of the elastic bulb, the tubular member defining a third conduit for controlling the pressure in a space defined between the tubular member and the bladder and urethra, a surgical connection between the bladder and urethra being exposed in the annular space. - View Dependent Claims (16, 17, 18, 19, 20)

21. A method for facilitating the healing of a surgical connection in a body lumen, comprising the steps of:
-
providing a first conduit in the lumen;
positioning a distal end portion of the first conduit distally beyond the surgical connection, the first conduit directing fluid through the lumen and isolating the fluid from the surgical connection;
providing a second conduit in the lumen;
positioning a distal end portion of the second conduit adjacent the surgical connection; and
regulating the pressure in a space in which the surgical connection is positioned via the second conduit. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
