Abstract
A surgical device such as a therapy device that can allow a surgeon to treat a target tissue with ultra-violet (UV) light ablation therapy. In one example, the therapy device is configured to treat menorrhagia. In that instance, the therapy device may be configured to effect or destroy the endometrium during a procedure treating menorrhagia.
Claims20
A therapy device for treating intra-uterine tissue, the therapy device including:
- a cannulated shaft extending from a proximal end to a distal end, the distal end having a distal opening;
- and
- a therapy light system configured to apply ultra-violet (UV) light to treat the intra-uterine tissue, wherein the therapy light system, includes:
- a first UV light source configured to generate a first UV light;
- and
- a second UV light source configured to generate a second UV light different from the first UV light.
A method of apply UV light to an intra-uterine tissue, the method includes:
- introducing a portion of a therapy device into a body cavity of a patient, the therapy device, including:
- a cannulated shaft extending from a proximal end to a distal end, the distal end having a distal opening;
- a therapy light system including:
- a first UV light source configured to generate a first UV light;
- and
- a second UV light source configured to generate a second UV light different from the first UV light;
- generating the first UV light;
- applying the first UV light to the intra-uterine tissue;
- generating the second UV light;
- and
- applying the second UV light to the intra-uterine tissue.
A therapy device for treating intra-uterine tissue, the therapy device including:
- a cannulated shaft extending from a proximal end to a distal end, the distal end having a distal opening;
- a therapy light system configured to apply ultra-violet (UV) light to treat the intra-uterine tissue, wherein the therapy light system, includes:
- a first UV light source configured to generate a first UV light;
- and
- a second UV light source configured to generate a second UV light different from the first UV light;
- a UV light transparent distention member translatable within the cannulated shaft configured to extend from the distal opening and distend a patient's uterus;
- a light source configured extend from the distal opening and illuminate the internal tissue of the body cavity;
- and
- an image visualization structure configured to visualize the internal tissue of the body cavity to a user.
