Device for insertion into a body cavity, and method of fabrication thereof

A method of fabricating a device for inserting into a body cavity, the method comprising:

• forming an insertion member configured to be inserted into the body cavity;
• providing at least one expandable member coupled to the insertion member, the at least one expandable member capable of being expanded to apply pressure onto tissue within the body cavity;
• forming a first member configured for storing a first endothermic reactant therein;
• and
• forming a second member configured for storing a second endothermic reactant therein;
• and
• configuring the first and second members for allowing, in a state of the device, the first and second endothermic reactants to cooperate to effect an endothermic reaction to generate an endothermic product,
• wherein said providing the at least one expandable member comprises configuring the at least one expandable member to receive at least one of the first endothermic reactant, the second endothermic reactant and the endothermic product through a channel within the insertion member,
• wherein at least the first member is configured to be compressible to cause the device to be in said state, wherein compressing the first member reduces a volume within the first member, thereby forcing the first endothermic reactant stored in the first member and/or the second endothermic reactant stored in the second member to flow to cooperate with each other to effect the endothermic reaction, and pressuring the at least one of the first endothermic reactant, the second endothermic reactant and the endothermic product to flow through the channel into the at least one expandable member for expanding the at least one expandable member, and
• wherein said forming an insertion member comprises configuring the insertion member to comprise a plurality of compartments arranged successively along the insertion member, each compartment having coupled therewith a respective expandable member, each of the respective expandable members capable of being expanded in response to the at least one of the first endothermic reactant, the second endothermic reactant and the endothermic product received from the respective compartment, wherein a plurality of valves are arranged in the channel of the insertion member, each valve arranged between adjacent compartments associated therewith and configured to allow the at least one of the first endothermic reactant, the second endothermic reactant and the endothermic product to flow through the valve from a first compartment of the adjacent compartments to a second compartment of the adjacent compartment when a pressure acting on the valve is equal to or exceeds a threshold pressure, the first compartment being closer to the first member than the second compartment.
