Abstract
An apparatus includes an optics tube extending from a proximal end to a distal end and a distal tip member positioned proximate the distal end of the optics tube. The optics tube includes a cladding material, a core material encased by the cladding material and configured to transmit light from the proximal end of optics tube to the distal end, and a lumen defined by the core material. A core wire is disposed in the lumen. The core wire is configured to prevent longitudinal stretching of the optics tube.
Claims20
An apparatus comprising:
- (a) an optics tube extending from a proximal end to a distal end, the optics tube comprising:
- (i) a cladding material,
- (ii) a core material encased by the cladding material and configured to transmit light from the proximal end of optics tube to the distal end, and
- (iii) a lumen defined by the core material;
- (b) a distal tip member positioned proximate to the distal end of the optics tube;
- and
- (c) a core wire disposed in the lumen, wherein the core wire is configured to prevent longitudinal stretching of the optics tube.

An apparatus comprising:
- (a) an optics tube extending from a proximal end to a distal end and formed from a core material encased in a cladding material;
- (b) a lumen defined by the core material and extending from the proximal end to the distal end, wherein the lumen is configured to selectively receive one or more of a core wire, an optical fiber, a forceps device, or a basket device;
- (c) a distal tip member secured to the distal end of the optics tube;
- and
- (d) a light source operably connected to the proximal end of the optics tube, wherein the core material is configured to transmit light from the light source to the distal tip member.
