Problems solved by technology

This curl is not determined at the factory according to the manufacturer's bracket specifications
Also, with this type of feedback loop to control jetting, nozzle position, and / or phantom position based only on "first impressions," freestyle systems can increase the time required to apply the coating

Embodiment Construction

[0158] The present invention is a method and apparatus suitable for use in an operating room to selectively apply a medical coating to an implantable medical device (eg, a stent) prior to an implantation procedure.

[0159] The principles and operation of the coating apparatus according to the present invention may be better understood with reference to the accompanying drawings and the corresponding description.

[0160] For the sake of presentation, the embodiments discussed here are devices for applying a medical coating to a stent deployed on a catheter, the coating being applied prior to the implantation procedure, in the operating room if desired conduct. The use of an optical scanning device enables the processing unit to distinguish between the surface area of ​​the stent and the surface area of ​​the catheter. The processing unit selectively activates the coating applicator to substantially apply the coating only to the stent and not to the balloon or other portion o...

Abstract

The present invention is a method and device, which is suitable for use in an operating theater just prior to implantation, for selectively applying a medical coating to an implantable medical device, for example a stent. Disclosed is a device for use with a stent deployed on a catheter balloon. The device is configured to apply a medical coating of a desired thickness to the surface of a stent only. This is done by use of a drop-on-demand inkjet printing system in association with an optical scanning device. The device is further configured so as to, if necessary, apply a plurality of layered coats, each layered coat being of a different coating material, and if appropriate, different thickness. The section of the housing in which the stent is held during the coating procedure is detachable from the housing base. The detachable housing section may be easily cleaned and re-sterilized or simply disposed or simply disposed of.

Description

[0001] This application is a continuation-in-part of US Patent Application No. 10 / 136,295, filed on May 2, 2002. technical field [0002] The present invention relates to a technology for coating medical devices for implantation in the body, in particular, to a method suitable for use in an operating room to selectively apply a medical coating to implantable devices prior to implantation surgery. Methods and devices on implanted medical devices such as stents. [0003] the term [0004] The term "prosthesis" refers to any of a number of medically coated devices including, but not limited to, coronary stents, branch vessel stents, abdominal aortic aneurysm (AAA) devices, bile duct stents and catheters, TIPS catheters and stents , vena cava filters, vascular filters and peripheral support devices and thrombus filters / retention aids, vascular implants and implanted stents, gastrointestinal tubes / stents, gastrointestinal and vascular anastomosis devices, urinary catheters and ste...
