1. A portable handheld device comprising:
a compliant surface engageable with a nose;
a body;
a head;
an irrigant reservoir;
an aspirant reservoir;
a first irrigant port;
a second irrigant port;
an aspirant port;
a first channel;
a second channel; and
a pump,
wherein the head, the irrigant reservoir, the aspirant reservoir, the first irrigant port, the aspirant port, the first channel, and the second channel are removably connectable to the body,
wherein the first channel has a first channel center longitudinal axis, wherein the second channel has a second channel center longitudinal axis, wherein when the head is removably connected to the body, the first channel is to one side of the second channel such that the first channel center longitudinal axis is offset from the second channel center longitudinal axis, such that the first channel center longitudinal axis passes through the first irrigant port, and such that the second channel center longitudinal axis passes through the aspirant port,
wherein when the head is removably connected to the body, the first channel is between the first irrigant port and the second irrigant port,
wherein when the head is removably connected to the body, the first channel is between the first irrigant port and the irrigant reservoir,
wherein when the head is removably connected to the body, the second channel is between the first irrigant port and the second irrigant port,
wherein when the head is removably connected to the body, the second channel is between the first irrigant port and the irrigant reservoir,
wherein when the head is removably connected to the body, the first irrigant port and the aspirant port are the same distance from the body,
wherein when the head is removably connected to the body, the first irrigant port and the aspirant port are distal the second irrigant port,
wherein when the head is removably connected to the body, the irrigant reservoir and the aspirant reservoir are proximal the first irrigant port,
wherein when the head is removably connected to the body, the irrigant reservoir and the aspirant reservoir are proximal the second irrigant port,
wherein when the head is removably connected to the body, the irrigant reservoir and the aspirant reservoir are proximal the aspirant port,
wherein when the head is removably connected to the body, the first irrigant port and the aspirant port are between the irrigant reservoir and the aspirant reservoir,
wherein when the head is removably connected to the body, the compliant surface is between the irrigant reservoir and the aspirant reservoir,
wherein when the head is removably connected to the body, the irrigant reservoir and the aspirant reservoir are on opposite sides of the portable handheld device,
wherein the first channel is positionable relative to the body in a first channel first position and a first channel second position, and wherein an end of the first channel is the same distance from the body when the first channel is in the first channel first position and when the first channel is in the first channel second position,
wherein the second channel is positionable relative to the body in a second channel first position and a second channel second position, and wherein an end of the second channel is the same distance from the body when the second channel is in the second channel first position and when the second channel is in the second channel second position,
wherein the irrigant reservoir comprises a first tapered shape,
wherein the aspirant reservoir comprises a second tapered shape,
wherein the first tapered shape is different than the second tapered shape, and
wherein the portable handheld device is configured to aspirate alone, irrigate alone, sequentially aspirate and irrigate, sequentially irrigate and aspirate, or simultaneously aspirate and irrigate.
