Abstract
A device for selecting sperm includes a stack of a plurality of layers of a material. The stack has an inlet end and an outlet end. Each layer of the material includes a plurality of sperm selection microchannels. Each sperm selection microchannel has a respective microchannel inlet at the inlet end of the stack and extends to a respective microchannel outlet at the outlet end of the stack.
Claims18
A device for selecting sperm, comprising:
- a stack of a plurality of layers of a material, the stack having an inlet end and an outlet end;
- and
- a core, wherein the material is wrapped around the core to form the stack;
- wherein each layer of the material comprises a plurality of sperm selection microchannels, wherein each sperm selection microchannel has a respective microchannel inlet at the inlet end of the stack and extends to a respective microchannel outlet at the outlet end of the stack.
1 more element
A kit of parts for selecting sperm, comprising:
- a device comprising a stack of a plurality of layers of a material and a core, wherein the material is wrapped around the core to form the stack, wherein the stack has an inlet end and an outlet end, wherein each layer of the material comprises a plurality of sperm selection microchannels, and each sperm selection microchannel has a respective microchannel inlet at the inlet end of the stack and extends to a respective microchannel outlet at the outlet end of the stack;
- and
- a vessel having an interior volume;
- wherein the device is connectable to the vessel to position the microchannel inlets in the interior volume, and wherein at least one of the device and the vessel provides a sperm collection reservoir in fluid communication with the microchannel outlets.
1 more element
A method for fabricating a sperm selection device, comprising:
- a. creating a plurality of sperm selection microchannels in a material, wherein each sperm selection microchannel has a microchannel inlet and a microchannel outlet;
- b. arranging the material into a stack of a plurality of layers of the material by wrapping the material around a core, so that the microchannel inlets are at an inlet end of the stack and the microchannel outlets are at an outlet end of the stack.
