Using the linear forces that are provided by an electromagnetic solenoid applied near the distal end of a medical catheter, various surgical instruments can be actuated or deployed for use in interventional medicine. The linear actuator uses the principles of magnetic repulsion and attraction as a means for moving a bobbin that can be attached to various types of moving components that translate linear movements into the actuation of a tool that is attached to the linear actuator. Using independent solenoid coils, movement modality is increased from two possible positions to three.

Cigarettes are manufactured using modified automated cigarette making apparatus. Those cigarettes possess smokable rods having paper wrapping materials having additive materials applied thereto as patterns. The additive materials, which can have the forms of liquid or paste formulations (e.g., aqueous formulations incorporating starch or modified starch), are applied to a continuous paper web on the cigarette making apparatus. The formulation is applied to the paper web using application apparatus possessing rollers a series of roller. For example, additive material is applied to the roll face of a transfer roller due to roll interaction of that transfer roller with a pick-up roller; roll interaction of the transfer roller with an application roller causes transfer of the additive material from the transfer roller to the application roller; and additive material from the application roller is transferred to the paper web that passes between the application roller and a back-up roller. A radiant dryer is used to dry the additive material that has been applied to the paper web. The radiant dryer is located on one component of a two component assembly that is used to manufacture cigarettes. A first component of the two component assembly provides a source of paper web, applies additive material to that web in a pattern and dries the paper web; while a second component receives the paper web, supplies tobacco filler and manufactures a cigarette rod from the paper web and tobacco filler. An alternate assembly system provides a source of paper web, applies additive material to that web in a pattern, dries the paper web, and winds the treated paper web on to a bobbin; and that bobbin is later used to provide a source of paper web on a cigarette making machine unrolls that bobbin, receives the treated paper web from that bobbin, supplies tobacco filler and manufactures a cigarette rod from the paper web and tobacco filler. Spectrometric techniques are used to ensure proper registration of the additive material on the cigarette rods so manufactured, and to ensure proper quality of those cigarettes.

Implants and methods for bone treatment, preferably minimally invasive treatment, including repositioning of vertebrae may comprise insertion of a bobbin having a wire, string, thread or band, coiled around the bobbin. During coiling, the diameter of the bobbing/band complex may increase. Such increase in diameter can push against the inner side of the endplates of the vertebral body, and augment the vertebral body to its original height. The implant may also take the form of a coiled sleeve which when inserted into the vertebral body is uncoiled. The force of the uncoiling sleeve pushes against the inner side o the endplates of the vertebral body, restoring the vertebral body to its original height. The implant may also take the form of fibrous masses comprised of a thread or other relatively thin structure, for example a fiber or strand, of any biocompatible material having desired characteristics, for example a shape memory alloy, titanium, stainless steel, another metal or metal alloy, a ceramic, a composite or any combination thereof. The, strand, thread or other fiber may be coiled, woven, matted, tangled or otherwise formed into a wool-like mass or body having a desired configuration. Expansion of the expandable member within the vertebral body or other bone may reposition the fractured bone to a desired height and augment the bone to maintain the desired height. A bone cement or other filler can be added to further treat and stabilize the vertebral body or other bone.
