Abstract: Methods of marking pharmaceutical products for use in clinical trials and for determining the origin or authenticity of the marked products are provided that use a variety of natural materials as markers. The natural materials have unique genetically controlled micromorphological structures that can be identified using enhanced visualization techniques. For example, cellulosic plant materials, sporopollenin and diatoms can be used as the natural materials. The natural materials are added to pharmaceutical products at sufficiently low levels so as not to have any significant effect on the products other than serving as markers. Dyes and reactants can be added to the natural materials to provide secondary markers. The markers can be identified in stool samples collected during clinical trials to prove that a particular pharmaceutical product has been ingested by a test subject.

Abstract: A phacoemulsification needle is disclosed having a hollow member with an inner surface, an outer surface, and a distal end tip. The distal end tip has an outer edge portion and an inner edge portion both of which are rounded to eliminate any sharp edges. The needle can be used to deliver ultrasonic energy to a surgical site, such as a cataract, to emulsify unwanted tissue and to aspirate the tissue through the lumen of the hollow member without using any sharp surfaces for cutting. The rounded outer and inner edge portions of the distal end tip of the needle increase the safety of the surgical procedure by reducing the risk of damage to the capsule or other intraocular structures or tissues near the surgical site. This improvement in safety has allowed the development of new needle configurations to improve the efficiency of phacoemulsification, several of which are disclosed herein.

Abstract: A catheter having a fibrous reinforcement is formed by anchoring a filament at a proximal end of a core member, and winding the filament onto the core member continuously from the proximal end to the distal end of the core member and then back to the proximal end to form a first fibrous layer. The filament is wound with a constant or variable pitch along the length of the core member. Additional fibrous layers can be applied by continuously winding a filament over the first fibrous layer from the proximal end to the distal end or to an intermediate position along the core member and then back to the proximal end. The additional layers can extend to different distal positions to form a catheter having a tapering profile. In alternative embodiments, catheters are formed by winding a group of filaments onto the core member simultaneously.
