Abstract: A method for treating actinic keratosis or basal cell carcinoma. A person's skin is inspected to identify areas that exhibit lesions indicating actinic keratosis or basel cell carcinoma. If such areas are found, a treating composition is applied to the skin in that area. The treating composition may include avobenzone, octocrylene, octyl salicylate, and oxybenzone, and optionally may additionally include SD alcohol 40, C12-15 alkyl benzoate, acrylates, octylacrylamide copolymer, hydroxypropyl cellulose, PEG-40 sorbitan peroleate, tocopherol, and aloe barbadensis extract. The skin is monitored regularly to determine whether the skin lesions remain, and the treating composition is applied several times daily for a period of at least two months until the area is substantially free of the lesions.

Abstract: A biopsy needle device (10) is provided which includes an introducer cannula (20) defining a lumen (25) sized to receive a biopsy needle (11) therethrough and a lateral opening (24) in communication with the lumen (25) adjacent the first end (21) of the cannula (20). The invention also includes a solid tip (30) having an anatomically distal end (31) secured to the first end (21) of the cannula (20) and a proximal end (32) configured to pierce tissue. A ramp (35) is disposed within the cannula (20) at an end (36) of the lateral opening (24) adjacent the first end (21) of the cannula (20). The ramp (35) is inclined toward the lateral opening (24), whereby a biopsy needle (11) will be deflected through the lateral opening (24) as it advances within the lumen (25) and exits the cannula (20).

Abstract: An apparatus and a method for non-invasively decomposing a calculus in a human body include a mechanism for, and the step of, locating the calculus, a mechanism for, and the step of, delivering to the site of the calculus a chemical species known to reduce the calculus, and a mechanism for, and the step of, generating an unfocussed beam of ultrasound radiation for insonating the calculus for enhancing the chemical dissolution of the calculus through the interaction of the calculus, the chemical species and the ultrasound radiation.
