a first neck; a first head connected to the body, wherein the first head comprises a compliant outer surface configured to seal against a nostril, and wherein the first head is configured to be detached from the body; a first port in the first head; an irrigant reservoir in direct fluid communication with the first port, and wherein the first port is configured to deliver an irrigant to outside of the head; a first channel in the first head, wherein the first channel terminates at the first port; a second port configured to receive an aspirant from outside of the first head; a second channel in the first head, wherein the second channel terminates at the second port, and wherein the first channel is to one side of the second channel; an aspirant reservoir in direct fluid communication with the second port; and a fluid control system comprising a pump, wherein the fluid control system is configured to control an irrigation delivery pressure of the irrigant outside of the first head, and wherein the fluid control system is configured to control an aspiration pressure into the first head. ### Claim 2 (depends on 1) The device of claim 1, wherein the fluid control system is configured to control the aspiration pressure concurrent with the irrigation delivery pressure. ### Claim 3 (depends on 1) The device of claim 1, further comprising an irrigant reservoir seal on a side of the first head. ### Claim 4 (depends on 3) The device of claim 3, wherein the irrigant reservoir is in fluid communication with the irrigant reservoir seal. ### Claim 5 (depends on 4) The device of claim 4, wherein the first head and first neck are configured to be detached together from the remainder of the device. ### Claim 6 (depends on 5) The device of claim 5, further comprising a second head and second neck, wherein the second head and second neck are configured to be attached to the remainder of the device in place of the first head and first neck after the detachment of the first head and first neck. ### Claim 7 (depends on 1) The device of claim 1, wherein the first neck is configured to articulate. ### Claim 8 (depends on 1) The device, of claim 1, wherein the first channel has a first axis, and wherein the second channel has a second axis, and wherein an extension of the first axis distal to a terminus of the first channel intersects an extension of the second axis distal to a terminus of the second channel. ### Claim 9 (depends on 1) The device of claim 1, wherein at least a length of the first channel is nonparallel with at least a length of the second channel. ### Claim 10 A portable, handheld device for irrigating with an irrigant and aspirating biological tissue and/or secretions comprising: a body; a first neck; a first head connected to the body, wherein the first head comprises a compliant outer surface configured to seal against a nostril, and wherein the first head is configured to be detached from the body; a first port in the first head; an irrigant reservoir in direct fluid communication with the first port, and wherein the first port is configured to deliver an irrigant to outside of the head; a first channel in the first head, wherein the first channel terminates at the first port; a second port configured to receive an aspirant from outside of the first head; a second channel in the first head, wherein the second channel terminates at the second port, and wherein at least a length of the first channel is nonparallel with at least a length of the second channel; an aspirant reservoir in direct fluid communication with the second port; and a fluid control system comprising a pump, wherein the fluid control system is configured to control an irrigation delivery pressure of the irrigant outside of the first head, and wherein the fluid control system is configured to control an aspiration pressure into the first head. ### Claim 11 (depends on 10) The device of claim 10, wherein the fluid control system is configured to control the aspiration pressure concurrent with the irrigation delivery pressure. ### Claim 12 (depends on 10) The device of claim 10, further comprising an irrigant reservoir seal on a lateral side of the first head. ### Claim 13 (depends on 10) The device of claim 10, wherein the irrigant reservoir is in fluid communication with the irrigant reservoir seal. ### Claim 14 (depends on 13) The device of claim 13, wherein the first head and first neck are configured to be detached together from the remainder of the device. ### Claim 15 (depends on 14) The device of claim 14, further comprising a second head and second neck, wherein the second head and second neck are configured to be attached to the remainder of the device in place of the first head and first neck after the detachment of the first head and first neck. ### Claim 16 (depends on 10) The device of claim 10, wherein the first neck is configured to articulate. ### Claim 17 (depends on 10) The device of claim 10, wherein the first channel has a first axis, and wherein the second channel has a second axis, and wherein an extension of the first axis distal to a terminus of the first channel intersects an extension of the second axis distal to a terminus of the second channel. ### Claim 18 A portable, handheld device for irrigating with an irrigant and aspirating biological tissue and/or secretions comprising: a body; a first neck; a first head connected to the body, wherein the first head comprises a compliant outer surface configured to seal against a nostril, and wherein the first head is configured to be detached from the body; a first port in the first head; an irrigant reservoir in direct fluid communication with the first port, and wherein the first port is configured to deliver an irrigant to outside of the head; a first channel in the first head, wherein the first channel terminates at the first port; a second port configured to receive an aspirant from outside of the first head; a second channel in the first head, wherein the second channel terminates at the second port, and wherein the first channel has a first axis, and wherein the second channel has a second axis, and wherein an extension of the first axis distal to a terminus of the first channel intersects an extension of the second axis distal to a terminus of the second channel; an aspirant reservoir in direct fluid communication with the second port; and a fluid control system comprising a pump, Wherein the fluid control system is configured to control an irrigation delivery pressure of the irrigant outside of the first head, and wherein the fluid control system is configured to control an aspiration pressure into the first head. ### Claim 19 (depends on 18) The device of claim 18, wherein the fluid control system is configured to control the aspiration pressure concurrent with the irrigation delivery pressure.
