Abstract: A method and apparatus for medically treating recessed body tissues with medicament fluid. The invention comprehends aspirating the tissue to be treated prior to the introduction of the medicament fluid thereto so as to provide an improved delivery thereof. The apparatus includes a delivery tube having distributed openings at the distal end thereof and structure for selectively connecting either an aspirating syringe or a medical fluid delivery syringe at the opposite end. A support is provided having structure for permitting rotation of the tube about its longitudinal axis. A cystoscope is provided to permit the doctor to observe the location of the distal tip of the treatment apparatus for accurate location thereof in carrying out the fluid delivery.

Abstract: A method and apparatus for implanting medication pellets, such as radioactive seeds in recessed body tissues, such as in a prostate gland. The invention utilizes structure for implanting a plurality of such pellets concurrently in accurately controlled disposition within the tissue and includes structure for effecting cauterization, or fulguration, of the tissue in the event of fluid exudation, such as bleeding.

Abstract: A method of providing medical treatment of the prostate area. A urethrally inserted apparatus having an outer sheath, and a removable obturator located within the sheath during insertion of the sheath into the urinary tract by way of the externally urethra orifice in the penis is disclosed. Once the sheath is inserted, the obturator portion is removed and a medication depositing structure is inserted into the sheath. The depositing structure carries selected medication, as for example, radioactive iodine seeds. The obturator may be provided with means for inserting a viewing lens element to assure that the appropriate location adjacent to the prostate is obtained. Once the medication depositing structure is adjacent a selected area in the prostate, the prostate is pierced by the depositing structure so as to position the medication within the selected area. The medication is released and the deposition structure is withdrawn from the sheath. Thereafter, the sheath is withdrawn from the urethra.

Abstract: An apparatus and method is disclosed for enabling the extraction of a biopsy sample from the prostate through the urinary tract and for performing medical treatment in the prostate area. The apparatus includes an outer sheath and removable obturator portion which is located within the sheath during insertion of the sheath into the urinary tract. Once the sheath has been inserted, a sampling portion is substituted for the obturator to enable the extraction of a biopsy sample. The configuration of the sampling portion which cooperates with the sheath during extraction of the biopsy sample includes adjacent tubes retained within the sheath and a harpoon-shaped needle movable through one of the tubes. The harpoon needle cooperates with the one tube to provide cutting and retention of the biopsy sample by movement of a shaft external to the sheath portion. The other tube enables the insertion of a light conducting pipe and lens structure to view the area from which the sample is taken.
