<p>A system and method of catheterization, includes a needle (22), a 'Y' chamber (27), a syringe or other chamber (46), a dilator, a sheath (80), a protective sleeve (92), and a shock sheath (100). This introduces a comprehensive, uniform and universal approach to catheterization. Discriminatory methods of treatment using the invention are described. Particular attention has been paid to current problems in catheterization and the prevention of transmission of communicable diseases from patient to practitioner and vice versa (e.g., the risk of contracting the HIV virus is substantially reduced using this system and method). The discriminatory treatment of diseases, in particular, cancer, is now rapid, safe and in some instances, novel. The invention makes possible substantial reductions in the cost of health care while improving the efficiency of diagnosis and treatment. The invention allows the practitioner to perform simultaneous diagnosis and treatment of diseases using the same procedure, regardless of their location in or on the body. The number and duration of hospitalization is minimized, and the quality of life and length of survival for the patient is improved.</p> |
