Disclosed is a stent having improved characteristics of its structural design and improved radiopacity characteristics. Specifically, the present invention is a stent that has circumferential sets of strut members at the ends of the stent and central sets of strut members that are longitudinally placed between the end sets of strut members. Optimal radiopacity is achieved when the end sets of strut members are more radiopaque as compared to the radiopacity of the central sets of strut members. Also disclosed is the concept of adjusting the strut width of the curved sections of the end and central sets of strut members so that equal strain in all curved sections is achieved as the stent is expanded even though the diagonals sections of the end sets of strut members are shorter than the diagonal sections of the central sets of strut members.

The present invention pertains to methods of preserving fresh produce with a produce preservative which extends the shelf life of fresh produce, particularly cut fresh produce. The produce preservative preserves the texture, flavor, appearance, crispness, and color of the fresh produce, particularly the exposed surface of the fresh produce. The method comprises the following steps: providing a solution of produce preservative comprising: water, magnesium ions or zinc ions or tin ions; and ascorbate ions, or erythorbate ions; wherein the magnesium ion or zinc ions or tin ions and ascorbate ions are present in a mole ratio of preferably from 0. 2:1 to 8:1, more preferably from 0. 75:1 to 8:1, more preferably from 1:1 to 4:1, most preferably 1. 5:1 to 3:1, applying said produce preservative to the produce; applying said produce preservative to the produce.

Medical devices, and in particular implantable medical devices, may be coated to minimize or substantially eliminate a biological organism's reaction to the introduction of the medical device to the organism. The medical devices may be coated with any number of biocompatible materials. Therapeutic drugs, agents or compounds may be mixed with the biocompatible materials and affixed to at least a portion of the medical device. These therapeutic drugs, agents or compounds may also further reduce a biological organism's reaction to the introduction of the medical device to the organism. In addition, these therapeutic drugs, agents and/or compounds may be utilized to promote healing, including the formation of blood clots. The drugs, agents, and/or compounds may also be utilized to treat specific diseases, including vulnerable plaque. Therapeutic agents may also be delivered to the region of a disease site. In regional delivery, liquid formulations may be desirable to increase the efficacy and deliverability of the particular drug. Also, the devices may be modified to promote endothelialization. Various materials and coating methodologies may be utilized to maintain the drugs, agents or compounds on the medical device until delivered and positioned. In addition, the devices utilized to deliver the implantable medical devices may be modified to reduce the potential for damaging the implantable medical device during deployment. Medical devices include stents, grafts, anastomotic devices, perivascular wraps, sutures and staples. In addition, various polymer combinations may be utilized to control the elution rates of the therapeutic drugs, agents and/or compounds from the implantable medical devices.

A biocompatible metallic material may be configured into any number of implantable medical devices including intraluminal stents. The intraluminal stents may be specifically configured to optimize the number of discrete equiaxed grains that comprise the wall dimension so as to provide the intended user with a high strength, controlled recoil device as a function of expanded inside diameter. One biocompatible metallic material may comprise a Cobalt-Chromium alloy having substantially reduced Iron and/or Silicon content.
