Abstract

An apparatus comprising: (a) a proximal tube having a proximal portion connectable to a suction apparatus, and having at least two channels extending distally along respective longitudinal axes from the proximal portion and being in fluid communication from the proximal portion; and (b) two or more formable or rigid hollow distal tubes, each terminating in a porous extraction port, each of the distal tubes having a proximal section configured to be retained in a respective one of the channels of the proximal tube, wherein the distal tubes are in fluid communication with the proximal portion of the proximal tube when retained in the proximal channels of the proximal tube. Each porous extraction port is sized for placement within a buccal sulcus or a lingual sulcus of a subject and, wherein each porous extraction port comprises a central lumen in fluid communication with a respective distal tube.

An apparatus comprising:

a proximal tube having a proximal portion adapted for connection to a suction and waste container apparatus, the proximal tube having at least two channels extending distally along respective longitudinal axes from the proximal portion and being in fluid communication with the proximal portion;
and
two or more formable or rigid hollow distal tubes each terminating in a porous extraction port at distal ends thereof, each of the distal tubes having a proximal section configured to be retained in a respective one of the channels of the proximal tube, wherein the two or more distal tubes are in fluid communication with the proximal portion of the proximal tube when retained in the channels of the proximal tube;
wherein each porous extraction port is sized for placement within a buccal sulcus or a lingual sulcus of a subject, and wherein each porous extraction port comprises a central lumen in fluid communication with one of the two or more distal tubes;
wherein the apparatus further comprising a bending tool configured to be used for bending at least one of the distal tubes to a desired shape, wherein the bending tool comprises:
a base sheet;
a first extension at a proximal section of the base sheet, the first extension extending perpendicularly to the base sheet, on a first surface of the base sheet;
a second extension located distally of the first extension, the second extension extending perpendicularly to the base sheet, on the first surface of the base sheet, the second extension having a curved shape curving about an axis perpendicular to the first surface of the base sheet;
a third extension extending perpendicularly to the base sheet, on the first surface of the base sheet, the third extension extending laterally and proximally from the second extension;
and a fourth extension extending perpendicularly to the base sheet, on the first surface of the base sheet, the fourth extension located distally from a lateral end section of the third extension, such that a gap is present between the third extension and the fourth extension.

wherein each of the distal tubes is configured for being rotatable about the longitudinal axis of a respective one of the channels while retained in the channel;
wherein the distal tubes are removably joinable to the proximal tube;
wherein the distal tubes are interference fit to the proximal channel;
wherein the longitudinal axes of the channels are parallel to each other;
wherein the two channels are in fluid communication latitudinally with each other, such that when the distal tubes are retained in the into the channels the proximal sections of the distal tubes touch each other and press against each other;
wherein at least one of the distal tubes has an intermediate section extending distally from the proximal section and a distal section extending distally from the intermediate section;
wherein the at least one of the distal tubes is:
(a) bendable such that the proximal section extends along a first axis, the intermediate section has a first bend that curves toward the proximal section, followed by a second bend, such that the distal section extends distally from the second bend substantially perpendicularly to the first axis;
or
(b) rigid and having the proximal section extending along a first axis, the intermediate section having a first bend that curves toward the proximal section, followed by a second bend, such that the distal section extends distally from the second bend substantially perpendicularly to the first axis;
and the apparatus further comprising a bending tool configured to be used for bending at least one of the distal tubes to a desired shape.
