Method and device for treatment of edema
First Claim
1. A therapeutic pad system comprising:
- a bladder defining a flow space for a fluid, the bladder having a distal portion with an inlet port into the flow space, and a proximal portion with an outlet port from the flow space;
a pump disposed in a fluid circuit with the bladder, the pump operable to circulate a fluid through the bladder, providing the fluid through the distal inlet port and receiving the fluid from the proximal outlet port;
a flexible liner adapted to wrap about the bladder, the liner having a plurality of compressible channels; and
a binder adapted to wrap about the flexible liner, the binder having a plurality of elastic straps.

Abstract
A therapeutic pad system (200) is disclosed for the treatment of edema, wherein the pressure applied to the user by the pad encourages the proximal flow of lymph. A fluid is provided to one or more bladder-type pads (220) in the pad through an inlet port (218) at a distal end of the pad, and is expelled from the bladder through an outlet port (220) at the proximal end of the bladder, thereby producing a pressure gradient across the pad. The system includes a flexible and compressible liner (250) filled with a number of small foam pieces (258) that is adapted to be wrapped about the therapeutic pad, and a relatively rugged, outer binder (270) that is securable about the liner (250). An advantage of the present system is that it may be applied in a number of different modes and combinations providing many treatment options.

20. A therapeutic pad system for treating edema, the system comprising:
-
a flexible bladder having a distal end and a proximal end, an inlet port disposed near the distal end of the bladder, and an outlet port disposed near the proximal end of the bladder;
a fluid circulation assembly attached to the inlet and outlet ports of the bladder for circulating a fluid therethrough;
a liner adapted to receive the flexible bladder, the liner having a soft outer shell defining a closed volume, wherein the closed volume is filled with foam pieces;
a binder adapted to receive the liner and the bladder, the binder having a plurality of flexible straps for securing the system to a user. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

32. A method for treating edema comprising the steps of:
-
wrapping a portion of a body to be treated with a bladder having a distally disposed inlet port and a proximally disposed outlet port, wherein a fluid is circulated through the bladder, entering the bladder through the inlet port and exiting the bladder through the outlet port;
wrapping the bladder with a liner comprising a soft outer layer defining a container having a plurality of enclosed channels, the enclosed channels being filled with foam pieces;
affixing the liner compressively about the user with a binder that is adapted to wrap about the liner; and
selectively cooling the fluid circulated through the bladder. - View Dependent Claims (33, 34, 35, 36)
