## Abstract

An illuminated microsurgical instrument is provided herein that includes a microsurgical instrument having a tubular member arranged to treat patient tissue at a surgical site, the tubular member having a distal tip, an inner surface, and an outer surface. The inner surface defines a lumen. The outer surface has a notch formed therein. The illuminated microsurgical instrument further includes an optical fiber arranged to deliver light to the surgical site. The optical fiber includes a proximal end arranged to receive a light beam from a light source and also includes a curved distal end arranged to emit light adjacent to the distal tip. A portion of the curved distal end is positioned within the notch and curves away from the tubular member.

wherein the outer surface of the tubular member has a notch formed therein;
wherein the outer surface includes a longitudinal groove formed therein, the optical fiber extending along the tubular member within the longitudinal groove, the notch having a depth greater than a depth of the longitudinal groove;
wherein the optical fiber is seated in the notch.

### Claim 2 (depends on 1)

The illuminated microsurgical instrument of claim 1, wherein the optical fiber is attached to the tubular member through an adhesive.

### Claim 3 (depends on 1)

The illuminated microsurgical instrument of claim 1, wherein the fiber distal tip is not curved away from the tubular member.

### Claim 4 (depends on 1)

The illuminated microsurgical instrument of claim 1, wherein the fiber distal tip is curved away from the tubular member.

### Claim 5 (depends on 1)

The illuminated microsurgical instrument of claim 1, further comprising a sleeve around the tubular member and the optical fiber.

### Claim 6

An illuminated microsurgical instrument comprising:
a microsurgical instrument having a tubular member arranged to treat patient tissue at a surgical site, the tubular member having a distal tip and an outer surface; and
an optical fiber arranged to deliver light to the surgical site, the optical fiber including a proximal end arranged to receive a light beam from a light source and also including a distal end with a fiber distal tip that includes a beveled end arranged to refract light away from the tubular member outer surface;
wherein the outer surface of the tubular member has a notch formed therein;
wherein the outer surface includes a longitudinal groove formed therein, the optical fiber extending along the tubular member within the longitudinal groove, the notch having a depth greater than a depth of the longitudinal groove;
wherein the distal end of the optical fiber is a curved distal end arranged to emit light adjacent to the distal tip, a portion of the curved distal end being positioned within the notch, the curved distal end curving away from the tubular member.

### Claim 7 (depends on 6)

The illuminated microsurgical instrument of claim 6, wherein the curved distal end of the optical fiber comprises a tapered fiber tip portion, wherein the tapered fiber tip portion of the curved distal end of the optical fiber comprises an opaque coating thereon.

### Claim 8 (depends on 6)

The illuminated microsurgical instrument of claim 6, wherein the curved distal end of the optical fiber comprises:
a first portion that curves into the notch; and
a second portion that curves out of the notch.

### Claim 9 (depends on 6)

The illuminated microsurgical instrument of claim 6, wherein the curved distal end is affixed within the notch by an opaque adhesive material that surrounds a portion of the curved distal end.

### Claim 10 (depends on 6)

The illuminated microsurgical instrument of claim 6, wherein a central axis of a lumen extending within the tubular member is offset from a central axis of the outer surface of the tubular member such that a thickness of the tubular member is greater on a side comprising the optical fiber than a thickness of the tubular member on an opposite side.

### Claim 11 (depends on 6)

The illuminated microsurgical instrument of claim 6, wherein the tip of the curved distal end comprises a lens that focuses the light beam in a near field of the light beam and diverges the light beam in a far field of the light beam.

### Claim 12 (depends on 6)

The illuminated microsurgical instrument of claim 6, wherein the microsurgical instrument is a vitrectomy probe.

### Claim 13 (depends on 6)

The illuminated microsurgical instrument of claim 6, wherein the outer surface of the tubular member comprises an angled section that provides a cutting edge disposed distal of a port on the tubular member outer surface, wherein at least the angled section comprises an anti-glare surface.

### Claim 14

A surgical system, the surgical system comprising:
a light source coupleable to an optical fiber to provide illumination at a distal end of the optical fiber; and
a vitrectomy subsystem having a vitrectomy cutter, the vitrectomy cutter including:
a tubular member with a distal tip and a lumen extending therein, the lumen being defined by an inner surface of a wall of the tubular member, the distal tip including a port extending through the wall of the tubular member; and

wherein the outer surface includes a longitudinal groove formed in the wall, the optical fiber extending along the tubular member within the longitudinal groove, wherein the notch has a depth greater than a depth of the longitudinal groove.

### Claim 15 (depends on 14)

The surgical system of claim 14, wherein the distal end of the optical fiber comprises:
a less distal portion that curves into the notch; and
a more distal portion that curves away from the lumen.

### Claim 16 (depends on 14)

### Claim 17 (depends on 14)

The surgical system of claim 14, further comprising a sleeve around the tubular member and the optical fiber.

### Claim 18

A vitrectomy cutter comprising:
a tubular member arranged to remove vitreous from within an eye of a patient, the tubular member having a distal tip and a lumen extending therein, the lumen being defined by an inner surface of a wall of the tubular member, the distal tip comprising a port extending through the wall of the tubular member to receive vitreous into the lumen; and
