摘要： In an embodiment, the invention provides a catheter suitable for use in performing a procedure within a vessel, lumen or organ of a living having a distal end which is steerable, such as upon the application of compression. The catheter may be of the over the wire type, or alternatively may be a rapid exchange catheter. The catheter may provide for a rotating element which may be used to open a clogged vessel, or alternatively to provide information about adjacent tissues, such as may be generated by imaging or guiding arrangements using tissue detection systems known in the art, e.g., ultrasound, optical coherence reflectometry, etc. For rapid exchange catheters having a rotating element, there is provided an offset drive assembly to allow the rotary force to be directed from alongside the guidewire to a location coaxial to and over the guidewire.

摘要： Centrifuges are useful to, among other things, remove red blood cells from whole blood and retain platelets and other factors in a reduced volume of plasma. Platelet rich plasma (PRP) and or platelet poor plasma (PPP) can be obtained rapidly and is ready for immediate injection into the host. Embodiments may include valves, operated manually or automatically, to open ports that discharge the excess red blood cells and the excess plasma into separate receivers while retaining the platelets and other factors in the centrifuge chamber. High speeds used allow simple and small embodiments to be used at the patient's side during surgical procedures. The embodiments can also be used for the separation of liquids or slurries in other fields such as, for example, the separation of pigments or lubricants.

摘要： A device suitable for removing material from a living being is provided, featuring at least an aspiration pump, powered by a motor. The aspiration pump and any optional infusate pump preferably feature a helical pumping mechanism, and operate at a high rate of rotation, thereby ensuring adequate pumping performance and flexibility. The helical pumping mechanism may be a helical coiled wire about a central core tube. The helical coil wire, whether together with, or independent of, the core tube, may be rotated to cause a pumping action. Additionally, a narrow crossing profile is maintained, ensuring that the device may reach more tortuous regions of the vasculature. In one embodiment, the system comprises a wire-guided mono-rail catheter with a working head mounted on a flexible portion of the catheter that can laterally displace away from the guide wire to facilitate thrombus removal. The working head may be operated to separate and move away from the guide wire to come within a closer proximity of the obstructive material to more effectively remove it from the vessel.

摘要： A transmyocardial revascularization system including a plurality of inserts formed of a material to elicit a healing response in tissue of the myocardium and deployment instruments and associated components for deploying the inserts into the wall of the myocardium. The inserts are arranged to be disposed within respective lumens or channels in the wall of the myocardium. The inserts can take various forms, e.g., be solid members, tubular members, or porous members, and may be resorbable, partially resorbable or non-resorbable. In some embodiments the inserts are arranged to be left in place within the channels in the wall of the myocardium to result in plural lumens which enable blood to flow therethrough and into contiguous capillaries. The deployment instruments are arranged to pierce the tissue of the myocardium from either the endocardium or the epicardium to insert the inserts into the myocardium, depending on the particular deployment instrument used. The deployment instruments may make use of a stabilizing device to stabilize them during the procedure of inserting the inserts into the myocardium. A controller may also be provided as part of the system to coordinate the operation of the deployment instrument with the cardiac cycle. The formation of the lumens can be achieved either by the inserts or by some other means, such as a piercing tip or an energy applicator forming a portion of the instrument. The inserts may include one or more of pharmaceuticals, biologically active agents, radiopaque materials, etc.
