1. A fluid collection device, comprising:
a fluid impermeable barrier at least partially defining a chamber, the fluid impermeable barrier also defining an opening extending therethrough, the opening configured to be positioned adjacent to a female urethra or have a male urethra positioned therethrough, the fluid impermeable barrier extending along a longitudinal axis;
at least one porous material disposed in the chamber;
at least one shape memory material being sized, shaped, and positioned to retain a selected geometric configuration, the at least one shape memory material exhibiting a length measured along a longitudinal axis of the at least one shape memory material, the length of the at least one shape memory material generally parallel to the longitudinal axis of the fluid impermeable barrier, the length of the at least one shape memory material 30% to 100% of a length of the fluid collection device; and
at least one cavity that directly receives the at least one shape memory material, the at least one cavity configured to have the at least one shape memory material inserted and/or removed therefrom.
 
15. A method to collect fluid, the method comprising:
positioning an opening of a fluid collection device adjacent to a female urethra or around a male urethra, the fluid collection device including:
a fluid impermeable barrier at least partially defining a chamber, the fluid impermeable barrier also defining an opening extending therethrough, the opening configured to be positioned adjacent to the female urethra or have the male urethra positioned therethrough, the fluid impermeable barrier extending along a longitudinal axis;
at least one porous material disposed in the chamber;
at least one shape memory material being sized, shaped, and positioned to retain a selected geometric configuration, the at least one shape memory material exhibiting a length measured along a longitudinal axis of the at least one shape memory material, the length of the at least one shape memory material generally parallel to the longitudinal axis of the fluid impermeable barrier, the length of the at least one shape memory material 30% to 100% of a length of the fluid collection device; and
at least one cavity that directly receives the at least one shape memory material, the at least one cavity configured to have the at least one shape memory material inserted and/or removed therefrom
shaping the fluid collection device into the selected geometric configuration, wherein the selected geometric configuration is complementary to contours of anatomy of a wearer in a region proximate to the female urethra or the male urethra of the wearer; and
receiving fluid from the female urethra or the male urethra into a chamber of the fluid collection device.
