Problems solved by technology

Existing methods of producing this rotation while keeping the stent submerged are insufficient because the pressure required to clamp the stent onto the anode and provide good electrical contact may be excessive and may result in a stent structure when the stent is rotated. damage to

Embodiment Construction

[0027] Embodiments of the invention relate to electropolishing systems that may include one or more electropolishing fixtures. Each electropolishing fixture can be configured for electropolishing a device, including a medical device. Embodiments of the electropolishing fixture include a lever arm configured to apply pressure to the device, the electrode, or both the device and the electrode during the electropolishing process. The lever arm can be conductive and deliver current to the area of ​​contact, or the lever arm can be insulating. Where the lever arm is insulated, the lever arm of the electropolishing fixture operates to exert pressure between the other conductive member (ie, the electrode or conductive mandrel) and the device. Embodiments of the invention are discussed in the context of a stent, which is an example of a medical device. Embodiments of the present invention are also applicable to electropolishing of other devices.

Abstract

An electropolishing system that includes electropolishing fixtures. The electropolishing fixtures include pendulum assemblies configured to establish electrical contact between a device being electropolished and an anode and to reposition the device during the electropolishing process.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Application No. 13 / 618,455, filed September 14, 2012, which is incorporated herein by reference in its entirety. Background technique [0003] Medical devices are an important part of the health industry and are responsible for the health of many people. Due to advanced medical device technology, many life-saving procedures are currently able to be performed. For example, stents are examples of medical devices used in various medical procedures. When used in the context of the vascular system, stents can function to prevent, open, or counteract the flow of blood if a patient's vessel is weakened or blocked. However, stents are not limited to the vasculature and can be applied in many systems and situations. [0004] The production of medical devices such as stents can be a complex process. Producing the stent includes forming struts arranged to provide strength and flexibility t...
