摘要:
Method of modifying the coating of a surface of a medical device by applying a coating to the surface of the medical device, exposing the medical device to an environmental condition that alters the coating morphology, and drying the coating on the medical device. The disclosed subject matter also provides a coated medical device whose one or more surfaces have been modified by this method.
摘要:
A system and method for coating an endoprosthesis involves an applicator capable of delivering a coating substance to the endoprosthesis without spraying. The applicator may have a tube or die through which a coating substance is moved upwards by capillary action or by means of a pump so as to form an accumulation of the coating substance at an upper portion of the applicator. The endoprosthesis can be lowered onto the accumulation, then axially translated or rotated in order to transfer the coating substance to selected portions of the endoprosthesis. The applicator is lowered and/or the endoprosthesis is raised in order to form gaps in the coating. Selective coating of abluminal or luminal surface of the endoprosthesis may also be performed by allowing the surface to skip on a liquid surface of a pool of the coating substance.
摘要:
An apparatus for weighing a stent includes a buffer for storing a stent support with a stent mounted thereon, a stent mounting and dismounting assembly that mounts and dismounts the stent from the stent support, a robotic arm for moving the stent support with the stent between the buffer and the stent mounting and dismounting assembly, and a scale assembly for weighing the stent. The stent mounting and dismounting assembly moves the stent into the scale assembly after the stent has been dismount from the stent support.

A system for inspecting cylinders according to various aspects of the present invention generally includes a roller assembly comprising a plurality of rollers configured to hold the cylinder. A light source illuminates the cylinder and a camera produces an image of at least a portion of the cylinder as the roller assembly rotates the cylinder about its longitudinal axis. A computer system is configured to control the roller assembly, light source, and camera and analyze the image to identify a defect associated with the cylinder.
摘要:
A method for aligning a stent with a stent support includes the steps of (1) placing a stent support and a stent mounted on the stent support in a vertically position with the stent support's first support element at a lower position and the stent support's second support element at an upper position; (2) obtaining a digital image of the stent support and stent; (3) analyzing the digital image of the stent support and stent to compute the vertical position of the stent's upper end; (4) computing a desired position of the second support element based on the position of the stent's upper end; and (5) using a positioning device to move the second support element to the desired position. The movement of the second support element causes the conical sections of the first and second support elements to engage the respective ends of the stent to center the stent around a core element of the stent support and to secure the stent in a longitudinal direction of the stent support.
