Abstract: A dispensing device which disperses medicate through a needle across a zone within a body. The device includes a needle which is, during use, becomes encapsulated within a tubular needle-receiving member, a reservoir in fluid communication with the needle, positioned within the housing, and in communication with the needle, a second reservoir, a reservoir-connecting conduit in communication with the reservoir, a fluid drive in communication with the fluid in the second reservoir and in communication with the reservoir-connecting conduit, and a linear drive attached to the needle or to the needle-receiving member. The fluid drive impel fluids from the second reservoir to the reservoir-connecting conduit and thus drives the therapeutic agent from the reservoir during the linear displacement of the needle towards the housing. Fluid communication from the therapeutic agent reservoir to the needle is maintained by the tubing during operation of the linear drive.

Abstract: A dispensing device which disperses medicate through a needle across a zone within a body with zero pressure differential. The device includes a needle which is, during use, becomes encapsulated within a tubular needle-receiving member, a therapeutic agent reservoir in fluid communication with the needle, positioned within said housing, and in communication with the needle, a second reservoir, a reservoir-connecting conduit in communication with the therapeutic agent reservoir, a fluid drive in communication with the fluid in the second reservoir and in communication with said reservoir-connecting conduit, and a linear drive attached to said needle or to said needle-receiving member.

Abstract: A minimally invasive method for drilling into bone and for providing for delivery of medical treatment is provided. The method includes use of a drilling system includes a miniature shaft, a bit, a guide tube encapsulating the shaft during drilling and a cortex adapter thereafter to prevent closure of the drilled hole, a stylet to prevent blockage of the resulting passage, and introduction for treatment following removal of the stylet. As a result, a hole, targeted towards a cancerous lesion within the bone, is possible.

Abstract: A minimally invasive and particularly small apparatus for drilling into bone and for providing for delivery of medical treatment is provided. The directional drilling apparatus includes a miniature shaft, a bit, first shaft-mounted thrust ring, second shaft-mounted thrust ring, a tubing jacket surrounding the shaft and intermediate the first and second shaft-mounted thrust rings, and a guide tube encapsulating the tubing jacket. As a result, a hole, targeted towards a cancerous lesion within the bone, is possible. After removal of the shaft and the tubing jacket, treatment may be introduced through the particularly small passage created by the directional drilling apparatus or through the passage via a capillary inserted through at least a portion of the guide tube and the passage, which guide tube may include a hypodermic needle.

Abstract: A syringe which disperses medicate across a zone in the body during apparent conventional operation. The improved syringe includes a barrel, a plunger, and an operating cylinder. In operation, the needle of the syringe is inserted into the body at the distal portion of the portion of the body which is to receive the medicate. A single arm is attached to the barrel and passes through an operating cylinder with a thumb rest on its top. As a result, in operation, the user draws the single arm up to the thumb rest, thus causing the syringe to withdraw during injection and leaving a patch of medicate during operation.

Abstract: This invention provides a safer and more effective treatment for non-intracavitary undesirable tissue masses, especially bone cancer and soft tissue tumors. The method involves the direct administration of a therapeutically-effective dose of a formulated radioisotope composition nearby or directly into the tissue mass. Small volumes of the composition are used. Administration of the dose for bone cancer may be done through a hole or multiple holes created in the bone using a miniature drill. Delivery of the dose directly into a tumor may be accomplished using a microsyringe or a miniature pump capable of accurately delivering microliter amounts of material.
