## Abstract

A method is provided for treating a gland or duct of a patient. In a particular embodiment, an obstruction in a gland or duct and the orifice thereof can be alleviated; in another, a substance can be injected thereinto; in yet another, the gland can be aspirated. The method includes the step of inserting an elongated probe into a gland or duct via an orifice thereinto. In some embodiments the probe can have a longitudinal lumen therethrough, with at least one distal hole through the probe wall in fluid communication with the lumen. The lumen can be used in concert with a source of suction for removing debris from the gland or duct, and/or with a source of a fluid and pumping means, for injecting a substance into the gland or duct.

## Claims

### Claim 1

A device for treating a gland or duct of a patient comprising:
a probe having an unsharpened elongated distal end with an outer diameter of approximately 150 μm or less and a length of approximately 6 mm or less;
wherein the probe has a longitudinal lumen extending therealong defined by a probe wall and a distal hole through the probe wall in fluid communication with the lumen, the distal hole positioned in the probe distal end;
wherein the elongated distal end is stainless steel; and
wherein the outer diameter of the elongated distal end is less than that of an adjacent portion of a remainder of the probe to which the elongated distal end is attached.

### Claim 2 (depends on 1)

The device recited in claim 1, further comprising a pump element in fluid communication with the lumen for pumping fluid through the lumen and out the distal hole.

### Claim 3 (depends on 1)

The device recited in claim 1, wherein the distal hole comprises a plurality of distal holes.

### Claim 4 (depends on 1)

The device recited in claim 1, wherein the probe lumen comprises a first lumen and a second lumen, and the distal hole comprises a first distal hole in fluid communication with the first lumen and a second distal hole in fluid communication with the second lumen, such that suction can applied to the first lumen while fluid is injected through the second lumen.

### Claim 5 (depends on 1)

The device recited in claim 1, further comprising an elongated element positioned at least partially within the probe lumen and movable relative thereto to protrude from the probe distal end.

### Claim 6 (depends on 5)

The device recited in claim 5, wherein the elongated element comprises a distal tip having a diameter greater than a diameter proximal thereof for assisting in obstruction removal.

### Claim 7 (depends on 5)

The device recited in claim 5, wherein the probe lumen comprises a first lumen and a second lumen, the distal hole comprises a first distal hole in fluid communication with the first lumen and a second distal hole in fluid communication with the second lumen, and the elongated element is positioned within the first lumen.

### Claim 8 (depends on 1)

The device recited in claim 1, wherein the probe has an obstruction-removing element adjacent the probe distal end adapted for dislodging debris from the gland or duct.

### Claim 9 (depends on 8)

The device recited in claim 8, wherein the obstruction-removing element comprises an abrasive surface on the probe distal end for exfoliating the gland or duct.

### Claim 10

A device for treating a gland or duct of a patient comprising:
a probe having an elongated distal end with an outer diameter of approximately 150 μm or less and a length of approximately 6 mm or less;
wherein the probe has a longitudinal lumen extending therealong defined by a probe wall and a distal hole through the probe wall in fluid communication with the lumen, the distal hole positioned in the probe distal end;
wherein the probe lumen comprises a first lumen and a second lumen, and the distal hole comprises a first distal hole in fluid communication with the first lumen and a second distal hole in fluid communication with the second lumen, such that suction can applied to the first lumen while fluid is injected through the second lumen; and
wherein the outer diameter of the elongated distal end is less than that of an adjacent portion of a remainder of the probe to which the elongated distal end is attached.

### Claim 11 (depends on 10)

The device recited in claim 10, further comprising an elongated element positioned at least partially within the probe lumen and movable relative thereto to protrude from the probe distal end.

### Claim 12 (depends on 11)

The device recited in claim 11, wherein the elongated element comprises a distal tip having a diameter greater than a diameter proximal thereof for assisting in obstruction removal.
