The present invention encompasses tools and a tool-holding retractor assembly. The retractor assembly spreads an incision and holds the incision open. At least one extension device, having a tool holder on one end, attaches to the assembly. The holder includes a selectively locking multi-axis adjustable mounting element adapted to grip a tool shaft. The mounting element acts as a universal mounting providing rotational and sliding movement of the tool shaft. The extension device adjusts to position the tool holder peripherally of the surgical field. Once the retractor is placed, the extension device provides full access to regions below the incision. The extension device allows the surgeon to chose the insertion point and insertion angle of the tool shaft.

A method and control system computing platform for a dialysis machine that uses Symmetric Multi-Processing (SMP) architecture. The SMP architecture tightly couples multiple (e.g., 2) independent processors by sharing memory between the processors. A single shared memory is used by both processors in order to facilitate communication between the processors and reduce cost by eliminating the expense of redundant memory. In this way, the two, or in general “N” processors, increase processor throughput by allowing the execution of N processes in parallel while without requiring extra memory and without having a single point of failure in the computer. In the event of a bus failure on the circuit card, the computer is reset using distributed hardware watchdogs. The watchdog reset signal is also sent to the hardware components of the dialysis machine in order to place the system in a safe.

An MRI-compatible electronic medical therapy system is provided for temporarily preventing current flow through an implanted lead wire in the presence of an induced radio frequency, magnetic, or static field. One or more normally closed switches are disposed in series between the AIMD and the one or more distal electrodes. The switch may be incorporated in the AIMD, lead wire, or within or adjacent to the electrode. The switch remains closed during normal AIMD-related therapy, but temporarily opens in the presence of an induced radio frequency, magnetic, or static field so as to prevent current flow through the electrode and lead wire. The switches prevent current from circulating that could be induced by a medical therapeutic diagnostic device, which can cause overheating of lead wires, excessive currents or temperatures and tissue damage.

The invention is a fibrin glue that avoids the use of fibrinogen and thus eliminates the need for premixing and premature clot formation. The fibrin glue of the invention comprises thrombin, thromboplastin and calcium and may have clotting Factors, VII, IX and X, and the like. The invention also comprises a biosealant for use with the fibrin glue without fibrinogen or for use alone. The biosealant is a two component mixture of gelatin/resorcinol and glyoxal/glutaraldehyde/4-(p-maleimidophenyl) butyric acid. The two components are mixed on use.

The web of the invention can comprise a super absorbent layer that can act as an moisture sensitive fuel shut-off valve, absorbent, adsorbant or reactant. The web of the invention can comprise a super absorbent fabric or layer made of a superabsorbent particle or fiber. The web can comprise a nanofiber layer having dispersed within the nanofiber layer a super absorbent particulate and optionally a second particulate material that can act as an absorbent, adsorbant or reactant. Fluid, gas or liquid, that flows through or by the assemblies of the invention can have any gas, liquid or solid material dispersed or dissolved in the fluid interact with the super absorbent particulate. If needed these materials can also react with, be absorbed by, or adsorbed onto, the active particulate within the nanofiber layer. The structures of the invention can act simply as flow-by reactive, absorptive, or adsorptive layers with no filtration properties, or the structures of the invention can be assembled into filters that can filter particulate from a mobile fluid in a flow-through mode while simultaneously reacting, absorbing, or adsorbing materials from the mobile fluid.

Systems and methods are described for laser ablation of an analyte from a specimen and capturing of the analyte in a dispensed solvent to form a testing solution. A solvent dispensing and extraction system can form a liquid microjunction with the specimen. The solvent dispensing and extraction system can include a surface sampling probe. The laser beam can be directed through the surface sampling probe. The surface sampling probe can also serve as an atomic force microscopy probe. The surface sampling probe can form a seal with the specimen. The testing solution including the analyte can then be analyzed using an analytical instrument or undergo further processing.

The present invention provides drilling systems for drilling wellbores. The drilling system includes an umbilical that passes through a wellhead and carries a drill bit. A drilling fluid system supplies drilling fluid into an annulus (supply line) between the umbilical and the wellbore, which discharges at the drill bit bottom and returns to the wellhead through the umbilical (return line) carrying the drill cuttings. A fluid circulation device, such as a turbine or centrifugal pump, is operated in the return line to provide the primary motive force for circulating drilling fluid through a fluid circuit formed by the supply line and return line. Optionally, a secondary fluid circulation device in fluid communication with the return line can cooperate with the fluid circulation device to circulate drilling fluid and/or a near bit fluid circulation device can be used to provide localized flow control or suction pressure to improve bit cleaning.

An applicator having a substantially hollow body for accommodating an ampoule of solution. The hollow body comprises an open proximal end for receiving the ampoule and an open distal end having a flange to accept an applicator pad for applying the solution. A back plug having a lever mechanism is inserted into the open proximal end of the applicator to activate the applicator and seal the applicator after activation. Advancement of the back plug lever mechanism into the hollow body pivots the body of the ampoule to break the neck, activatiug the applicator. The back plug seals the proximal end after activation of the applicator.

An applicator for an anti-microbial solution includes an aerosol container and an applicator pad assembly having a hollow arm. The hollow arm has a proximal end attached to an aerosol cap and a distal end having a flanged arm plate to receive a foam applicator pad. The aerosol cap is removably attached to the aerosol container. A solution flow control is in communication with the aerosol container for selectively dispensing the anti-microbial solution. The aerosol container holds the anti-microbial solution under pressure and flow is controlled by a pressure-sensitive flow control tab. The control tab activates the flow of the anti-microbial solution from the aerosol container through the hollow handle to the foam pad and then to the patient. The control tab may be actuated by touch or by pressure applied to the applicator pad. An optional flow control feature, in addition to the control tab, is a slit formed in the foam pad. The slit is designed so that it remains closed when no pressure is exerted on the distal surface of the foam pad. However, when pressure is exerted on the distal surface of the foam pad, such as when the applicator is pressed against a patient's skin, the slit opens to allow the anti-microbial solution to flow past the slit into the foam pad. There the anti-microbial solution can be easily distributed over the patient's skin by the foam pad. When a sufficient amount of the anti-microbial solution has flowed into the foam pad, the healthcare professional can release the pressure sensitive control tab to stop the flow of anti-microbial solution out of the aerosol container.
