Abstract
Apparatus and methods for ocular treatment are provided. The apparatus can comprise a microcannula having a proximal end, a distal end, a cavity, and a central longitudinal axis. The apparatus can include a handle coupled to the proximal end of the microcannula. The apparatus can include multiple orifices extending circumferentially about the microcannula distal end, each of the orifices defining a channel extending transverse to the central longitudinal axis, and one or more grooves about a circumference of the microcannula.
Claims19
A medical device comprising:
- a microcannula having a proximal end, a distal tip, and a cavity, the microcannula having a central longitudinal axis;
- a handle coupled to the proximal end of the microcannula;
- a plurality of orifices extending circumferentially about the distal tip of the microcannula, the plurality of orifices each defining a channel extending transverse to the central longitudinal axis and having a radially outer end positioned radially farther away from the central longitudinal axis than a radially inner end, and the plurality of orifices each configured to deliver a substance radially outwardly from the distal tip of the microcannula;
- one or more grooves about a circumference of the microcannula;
- an outer tube, wherein the microcannula is housed within the outer tube, the outer tube comprising an opening located at a distal end of the outer tube;
- and
- a control mechanism located proximal to the handle, the control mechanism configured to move the outer tube from a first position to a second position, wherein a first orifice is covered in the first position and the first orifice is exposed in the second position.

A method of delivering fluid, comprising:
- inserting a microcannula through an incision in an anterior chamber of an eye, the microcannula including a proximal end, a distal tip, and a cavity, the microcannula having a central longitudinal axis with the proximal end of the microcannula being coupled to a handle and one or more grooves located at the distal tip of the microcannula;
- advancing the distal tip of the microcannula through a trabecular meshwork of the eye and into Schlemm's canal of the eye;
- delivering fluid through a plurality of orifices positioned within the Schlemm's canal, the plurality of orifices extending circumferentially about the distal tip of the microcannula, the plurality of orifices each defining a channel extending transverse to the central longitudinal axis and having a radially outer end positioned radially farther away from the central longitudinal axis than a radially inner end such that the fluid is delivered radially outwardly from the distal tip of the microcannula;
- and moving, by a control mechanism located proximal to the handle, an outer tube housing the microcannula to one of a first position that exposes a first orifice and a second position that covers the first orifice.
