Methods and apparatus for removing veins
View Patent ↗A method for removing a vein includes making an incision through a skin layer of a patient, inserting a surgical instrument through the incision, visualizing the vein through the skin layer using a light source positioned subcutaneously and in proximity of the vein, and cutting the vein using the surgical instrument. The vein can be visualized by directing light from the light source at the vein from underneath the vein or from a side of the vein. A device for illuminating a body structure has a housing with a distal end configured for subcutaneous insertion into a patient's tissue and positioning in proximity of the body structure, a light path supported by the housing and configured for directing light at the body structure, and a fluid line supported by the housing.
1. A device for illuminating a body structure, consisting of:
a housing having a distal portion configured for subcutaneous insertion into a patient's tissue and positioning in proximity of the body structure, and a proximal portion having a proximally facing surface having two connectors extending therefrom,
a light path supported by the housing and configured for directing light at the body structure, wherein one of the connectors connects to the light path, and
a fluid line supported by the housing, wherein the other of the connectors connects to the fluid line.
2. The device of claim 1 wherein the light path connector extends substantially in the direction of a longitudinal axis of the housing.
3. The device of claim 1 wherein the housing includes a generally hour glassed-shape handle in cross-section.
4. The device of claim 1 wherein the light path comprises a fiberoptic.
5. The device of claim 4 wherein the fiberoptic comprises a fiberoptic bundle.
6. The device of claim 1 wherein a distal end of the light path is oriented at an oblique angle to a longitudinal axis of the housing.
7. The device of claim 1 wherein the distal portion of the housing is oriented at an oblique angle to a longitudinal axis of the housing.
8. The device of claim 1 wherein a distal end of the light path and the distal portion of the housing are oriented at an oblique angle to a longitudinal axis of the housing.
9. The device of claim 1 wherein the fluid line is substantially straight.
10. The device of claim 1 wherein the light path is curved.
