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.

Methods and apparatus for removing veins

The present invention relates to devices and methods for the filling syringes. One medical apparatus in accordance with the present invention include a body member for releasably holding syringe barrels and an actuator apparatus slidably mounted on the body member to engage syringe plungers to cause the syringe plunger to be retracted. A fluid delivery apparatus is releasably mounted to the body member. The fluid delivery apparatus has an inlet port and a plurality of outlet ports. The inlet port is in fluid communication with each of the plurality of outlet ports. One method for filling a plurality of syringes in accordance with the present invention includes the steps of mounting a plurality a syringes to a syringe holding member and connecting a fluid delivery apparatus to the syringe holding member to mate with each of the tips of the syringe barrels. The method also includes the steps of placing an inlet port of the fluid delivery apparatus in a fluid and moving an actuator apparatus to retract the syringe plungers to cause fluid to enter the syringe barrels.

Syringe filling apparatus

The present invention relates to devices and methods for removing veins in a venous system of a patient. One device for removing undesired veins includes an elongated member having first and second lumens extending longitudinally therein. The first lumen extends from the proximal end of the elongated member to a first opening at the distal end of the member. The second lumen extends from the proximal end of the elongated member to a second opening in the side of the elongated member. The proximal end of the elongated body is coupled to a connector having two separate tubes that communicate with the respective first and second lumen for the injection and removal of fluid. A vein attachment member, attached to the elongated member, is adapted to be secured to the vein. One method of removing undesired veins includes the steps of inserting a surgical instrument into a lumen of the vein, advancing the surgical instrument to a desired point along the vein, and attaching the distal end of the vein to the surgical instrument. The method also includes the steps extracting the surgical instrument to cause the vein to separate from its surrounding tissue, and supplying fluid through the instrument into the tissue where the vein has been extracted.

Apparatus and methods for removing veins

The present invention relates to devices and methods for removing veins in a venous system of a patient. One device includes an elongated shaft having a first end and a second end, the second end of the first elongated shaft sized for insertion into an incision of a patient and a cutting head associated with the second end of the elongated shaft and being movable in response to electrical energy, the cutting head being constructed to cut veins into small pieces of a patient that are exposed to the cutting head. A method of removing varicose veins is also provided. The method includes the steps of making at least one incision through the skin layer of a patient in close proximity the undesired veins, inserting a distal end of a surgical instrument having a cutting element, and advancing the cutting element end of the surgical instrument to a position adjacent to a selected vein. The method function includes the steps of energizing surgical instrument to cause the cutting element to move at a desired speed, contacting the cutting element against the undesired vein while the cutting element is moving to break up the vein into particles, and withdrawing the distal end of the surgical instrument and closing the at least one small incision.
