Method of dispensing fluid are disclosed. The method initially determines, based upon an image of a first electronic substrate, that a first or a second dispense region is misaligned relative to the other of the first or the second dispense region. Fluid is dispensed from a first applicator while moving the first applicator using a primary positioner on the first electronic substrate to form a first fluid pattern. Fluid is simultaneously dispensed from a second applicator while moving the second applicator using the primary positioner and a secondary positioner. The method then determines, based upon an image of a second electronic substrate, that a first and a second dispense region of the second electronic substrate are aligned relative to one another. Fluid is simultaneously dispensed from the first applicator and the second applicator while moving the first applicator and the second applicator together using the primary positioner with first applicator.

Methods of dispensing fluid are disclosed. A first applicator is positioned above a first dispense site at a first dispense region of a first electronic substrate by moving the first applicator using a primary positioner. A second applicator is simultaneously positioned above a first dispense site at a second dispense region of the first electronic substrate by moving the second applicator together with the first applicator using the primary positioner and moving the second applicator relative to the first applicator using a secondary positioner. It is then determined that the first or the second dispense region is misaligned relative to the other of the first or the second dispense region. Fluid is dispensed from the first applicator while moving the first applicator using the primary positioner to form a first fluid pattern at the first dispense region and fluid is simultaneously dispensed from the second applicator while moving the second applicator using the primary positioner and the secondary positioner.

Systems for dispensing fluid in a first fluid pattern at a first dispense region and in a second fluid pattern at a second dispense region on one or more electronic substrates are disclosed. The system includes a primary positioner, a secondary positioner providing movement in the X axis direction and the Y axis direction relative to the primary positioner, a first applicator for dispensing fluid while being moved by the primary positioner, a second applicator for dispensing fluid while being moved by the primary positioner and/or the secondary positioner, a camera, and a controller. The controller determines a position of the first dispense region and a position of the second dispense region, controls movement of the primary positioner and the secondary positioner, and controls the first and second applicators to simultaneously dispense the first and second fluid patterns onto the respective first and second dispense regions.

A multiple stent structure including a plurality of stent bodies arranged end to end in which adjacent stent bodies of the structure are connected by a severable connecting portion disposed between the adjacent stent bodies is disclosed. A method of coating a plurality of stents including depositing a coating on the multiple stent structure and severing the severable connecting portions to disconnect the plurality of stent bodies is disclosed.

Methods for simultaneously dispensing a first fluid pattern at a first dispense region with a first applicator and a second fluid pattern at a second dispense region with a second applicator. The first and second applicators are moved toward their respective dispense regions with a positioner. While dispensing, the second applicator is moved relative to the first applicator in a direction or directions parallel to a first axis, a second axis, and/or a third axis, the axes being mutually orthogonal. The first dispense region may be provided with a unique first tilt and/or a unique first contour relative to the reference plane and along the third axis. Systems for dispensing fluid include a primary positioner supporting a first applicator, and a secondary positioner coupled to the primary positioner and supporting a second applicator and configured to move the second applicator relative to the first applicator.

Embodiments herein include apparatus and methods for coating medical devices. In an embodiment, a coating apparatus is included having a coating application unit including a movement restriction structure, a fluid applicator having a lengthwise major axis, a fluid distribution bar having a body angled with respect to the major lengthwise axis of the fluid applicator between 0 and 20 degrees, a rotation mechanism and an axial motion mechanism. The axial motion mechanism configured to cause movement of at least one of the coating application unit and the rotation mechanism with respect to one another. Other embodiments are also included herein.

A method is disclosed for forming a coating layer on an outer surface of a balloon of a balloon catheter. The method includes supplying a coating solution containing a drug and a solvent through an end portion of a flexible dispensing tube with an opening portion for discharging the coating solution through the end portion of the flexible dispensing tube; keeping in contact an opening portion-formed end portion side of the dispensing tube with the outer surface of the balloon in such a manner as to be oriented in a direction opposite to a rotating direction of the balloon; rotating the balloon about an axis of the balloon; and discharging the coating solution through the opening portion and applying the coating solution to the outer surface of the balloon while the dispensing tube is moved relative to the balloon in an axial direction of the balloon.

A balloon coating method is disclosed for forming a coating layer on an outer surface of a balloon of a balloon catheter. The method includes an application step where a vertically extending dispensing tube for supplying a coating solution containing the water-insoluble drug and a solvent is formed at its end portion with an opening portion for discharging the coating solution therethrough and when an opening portion-formed end portion side of the dispensing tube is kept in contact with the outer surface of the balloon in such a manner as to be oriented to a rotating direction of the balloon while the balloon is rotated about an axis of the balloon, the coating solution is discharged through the opening portion and applied to the outer surface of the balloon while the dispensing tube is moved relative to the balloon in an axial direction of the balloon.

A method for forming a coating on a stent involves spraying or drying a coating on the stent while the stent is supported on a mandrel assembly, during which part of the stent is made to go out of contact with the mandrel assembly.

A system paints the external and internal faces of a splayed end of a hollow shaft, with a rotary paint bench. This splayed end includes an end support face and an opposite support face. The system includes a fixing ring applied against the end support face and a counter-ring applied against the opposite support face as well as a fixing device, an end hub fixed to the fixing ring in line with the splayed end, and including a running belt suitable for resting on two rollers of the bench, a hollow external hub including two half-hubs delimiting a running belt suitable for resting on two rollers of the bench, and fixed to the counter-ring while surrounding the splayed end.
