Abstract: Various embodiments of devices and systems comprising a polymer driveshaft for use in high-speed rotational medical procedures, e.g., atherectomy, are disclosed. Generally, the primary driveshaft for transferring torque and activating rotation of a tool attached thereto, e.g., an abrasive element, is constructed with at least a polymer outer and inner surface. In certain embodiments, the polymer driveshaft may comprise a metallic band for fixed attachment of a structure, e.g., an abrasive element, thereto. Various embodiments may comprise a coupler that connects a drive shaft connected with a prime mover, e.g., a turbine or electric motor, with the polymer drive shaft, the coupler comprising openings through the coupler wall to the inner diameter of the coupler to allow fluid flow to the inner diameter of the coupled polymer drive shaft.

Abstract: The invention includes an assembly for anastomosis having a clamp being arranged to support a fastener. The clamp can be actuated to join a vessel with the fastener to establish a fluid communication. In some embodiments, the invention includes an assembly having a clamp and a fastener with first and second joinable parts, and the assembly can be adapted to facilitate the alignment of the first and second joinable parts.

Abstract: A vascular coupler adapted to be fixed into position upon a blood vessel and there retain and position a matable sensing device. In a preferred embodiment, the vascular coupler is an anastomotic coupler and the sensing device comprises an ultrasonic Doppler probe.

Abstract: An apparatus for accurately infusing medicinal agents into an ambulatory patient at specific rates over extended periods of time. The apparatus is of a compact, low profile, laminate construction and includes an elastic distendable membrane, chamber having a fluid outlet. Disposed within the fluid chamber is a thin fluid permeable member which precisely controls the rate of fluid flow through the fluid outlet. The apparatus also includes a highly novel fluid flow indicator that provides a readily discernible visible indication of fluid flow through the apparatus. Additionally, the apparatus includes a fill assembly comprising a prefilled vial that can be used to fill the fluid reservoir of the device with a selected medicinal fluid.

Abstract: A mounting apparatus for a work object dependent for operation upon at least one subsystem, the mounting apparatus comprising an assembly adapted for attachment to said work object; a main mount adapted to be secured on a means of support; and a frame mounted on and interconnecting said assembly and said main mount having at least one outwardly facing surface mounting said subsystem of the work object for ease of access thereto.
