A variety of medical devices including staples sutures and dental floss with surface treatment on at least one tissue-facing surface to improve biologic function such as to control tissue adhesion are disclosed including heparin surface treatment which provides heparin present in an amount to yield heparin bioactivity of at least one of i) an ATIII binding of at least 2 pmol/cm.sup.2, and ii) a thrombin deactivation of at least 0.2 IU/cm.sup.2; an acrylic surface treatment for coupling thereto of a heparin surface treatment, a collagen surface treatment or both; and an amino-functional polysiloxane surface treatment for coupling thereto of a heparin surface treatment.

A reactor for coating particles includes a stationary vacuum chamber to hold a bed of particles to be coated, a chemical delivery system, and a paddle assembly. The paddle assembly includes a rotatable drive shaft and a first plurality of paddles and a second plurality of paddles that extend radially from the drive shaft. The spacing, cross-sections, and oblique angles of the paddles are such that orbiting of the paddles causes the first plurality of paddles and the second plurality of paddles to displace substantially equal volumes in opposite directions in the lower portion of the stationary vacuum chamber.

A continuous dosage form coating apparatus uses vibrational impulses to maintain a dosage forms in a fluid state to expose them to a coating material atomized by spraying.

Some embodiments of the disclosure describe a batch coating apparatus. In some examples, the batch coating apparatus includes a fixing mechanism, a liquid holding mechanism, a liquid injection mechanism and a control device. The fixing mechanism includes a plurality of fixing portions for fixing work-pieces to be coated. The liquid holding mechanism includes a plurality of liquid tanks arranged side by side. The liquid injection mechanism includes a liquid storage portion and an infusion portion. The control device is configured to control at least one of a relative movement between the fixing mechanism and the liquid holding mechanism and a relative movement between the liquid holding mechanism and the liquid injection mechanism. The control device is configured to control the liquid injection mechanism to supply the coating liquid via the infusion portion.

An apparatus including an air blower; a rotary airlock; a receptacle having an inner chamber supplied with a plurality of colorant particles; a water supply; and a mixing chamber. The air blower blows air into a bottom section of the rotary airlock, and the rotary airlock receives colorant particles from an output of the receptacle. A rotor shaft of the rotary airlock rotates to cause colorant particles to be transported to the bottom section of the rotary airlock. Air blown into the bottom section of the rotary airlock mixes with colorant particles transported into the bottom section of the rotary airlock to form an air and colorant particles mixture, which is blown out of a first output of the rotary airlock and combined with water to form a water, air, and colorant particles mixture, which is mixed with material in a mixing chamber. The material may be natural mulch.

A coating apparatus unit for producing granules that are functionally coated with a coating agent and a method for producing granules that are functionally coated with a coating agent. The coating apparatus includes a coating chamber and a spraying device arranged in the coating chamber for spraying the coating agent. The coating apparatus unit further includes a process analysis tool and an electronic evaluation unit. The process analysis tool is designed to measure the active ingredient content of the granules, which is forwarded to the evaluation unit, so that the increase in mass of the granules can be determined in the evaluation unit by means of the coating agent applied to the granules, taking into account the measured active ingredient content of the granules.

The invention relates to a coating arrangement for coating particles, a method for coating particles, and corresponding uses. The coating arrangement includes a coating chamber and a coating device arranged in the coating chamber. This device comprises a hollow body with an axis, the inner wall of which forms a particle track around the axis of the hollow body, a particle source and a particle sink, and at least one coating source. The coating source is adapted for emitting a coating material along a direction perpendicular to the axis of the hollow body. Furthermore, the coating device comprises a rotation device which is adapted for rotating the hollow body about its axis, and a cleaning device which is arranged in the interior of the hollow body in a stationary manner with respect to the hollow body and is adapted for removing adhering coating material from the inner wall of the hollow body.
