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, Calkyl 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.

Method of treating actinic keratosis and basal cell carcinoma

A guide ( ) is provided for biopsy and microtherapy which includes an introducer cannula ( ) defining a lumen ( ) sized to receive a diagnostic or therapeutic item therethrough and a lateral opening ( ) in communication with the lumen ( ) adjacent the first end ( ) of the cannula ( ). The invention also includes a solid tip ( ) having an anatomically distal end ( ) secured to the first end ( ) of the cannula ( ) and a proximal end ( ) configured to pierce tissue. A ramp ( ) is disposed within the cannula ( ) at an end ( ) of the lateral opening ( ) adjacent the first end ( ) of the cannula ( ). The ramp ( ) is inclined toward the lateral opening ( ), whereby the item will be deflected through the lateral opening ( ) as it advances within the lumen ( ) and exits the cannula ( ). In some embodiments, the item is a biopsy needle, ablation means or a radiopharmaceutical seed. The invention also includes methods of obtaining a biopsy sample and methods for treating lesions.

Surgical and pharmaceutical site access guide and methods

A biopsy-marking assembly for obtaining a biopsy sample from a biopsy site in a patient and marking the biopsy site is provided. The biopsy marking assembly includes a biopsy device and a marking element for marking the biopsy site. In preferred embodiments, the marking assembly is configured so that the marking element is deposited at the biopsy site before the tissue sample is taken. In some embodiments, the marker element is a V-shaped rod including two legs and a joint between the two legs. In some embodiments, the biopsy device includes an outer hollow needle defining a lumen therethrough and an inner needle slidingly engaged within the lumen. The inner needle defines a marker chamber for carrying the marker element for delivery to the biopsy site, and a cavity for receiving a tissue sample. Methods are also provided for obtaining a biopsy sample and marking the biopsy site. The methods include loading a marker element into a biopsy device to obtain a biopsy-marker assembly, inserting the biopsy-marker assembly into a patient, depositing the marker element in the biopsy site and then obtaining a biopsy sample.

The methods include loading a marker element into a biopsy device to obtain a biopsy-marker assembly, inserting the biopsy-marker assembly into a patient, depositing the marker element in the biopsy site and then obtaining a biopsy sample. In a preferred embodiment, the methods include rotating the biopsy device after depositing the marker element and before obtaining the biopsy sample.

A suturing assembly is provided which includes a cannula with first and second ends. A first portion adjacent the first end defines a proximal lumen for slidably receiving a needle, a first bend and a needle exit aperture at the first bend in communication with the proximal lumen. The first lumen and the needle exit aperture define a needle path. A second portion is adjacent the second end and defines a distal lumen. The cannula defines a second bend between the first bend and the second portion. A needle entrance aperture is defined in the second portion in communication with the distal lumen and in line with the needle path. The cannula defines a first opening in the first end in communication with the proximal lumen. A needle with a piercing end is slidably disposed within the proximal lumen. The needle has a first position within the proximal lumen and a second deployed position with the piercing end in the distal lumen and the opposite end in the proximal lumen. A suture is secured to the needle and extends through the proximal lumen, the exit aperture, the entrance aperture and the second opening. Methods are also provided which include inserting the first end of the cannula into a wound so that the exit aperture contacts an inner surface of tissue surrounding the wound and deploying the piercing end of the needle through the needle exit aperture, the tissue and into the entrance aperture by applying a force on the suture extending from the second end.

Suturing assembly and method of use

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). The invention also includes methods of obtaining a biopsy sample using the biopsy device 10 in which a sample is taken, the biopsy needle (11) is retracted, the cannula (20) is rotated and the needle 11 is readvanced to obtain another sample from a different site.
