First Claim
Patent Images
1. A system for coating a stent, comprising:
- a device for weighing a stent;
a gripper configured to move the stent, from the device for weighing, onto a stent support;
a device for aligning the stent with the stent support such that the stent is coaxial with the stent support;
a device for coating the stent while the stent is on and coaxial with the stent support, the device for coating including a device configured to discharge a coating composition toward the stent and a device configured to rotate the stent support while the stent is on and coaxial with the stent support;
a device for drying the stent; and
a device for inspecting the stent wherein the device for aligning includes a camera configured to take an image of the stent, a computer configured to receive the image and to provide a signal based on the image, and a mechanism configured to move a first portion of the stent support relative to a second portion of the stent support based on the signal.

2. A method for coating a stent, comprising:
-
weighing a stent using a device for weighing a stent; moving the stent, from the device for weighing, onto a stent support; aligning the stent with the stent support such that the stent is coaxial with the stent support; coating the stent while the stent is on and coaxial with the stent support, the coating of the stent including discharging a coating composition toward the stent and rotating the stent support during the discharging and while the stent is on and coaxial with the stent support; drying the stent; and inspecting the stent wherein the aligning of the stent includes taking an image of the stent, providing a signal based on the image, moving a first portion of the stent support relative to a second portion of the stent support based on the signal. - View Dependent Claims (5, 6)
