Methods for forming a support frame for flexible leaflet heart valves from a starting blank include converting a two-dimensional starting blank into the three-dimensional support frame. The material may be superelastic, such as NITINOL, and the method may include bending the 2-D blank into the 3-D form and shape setting it. A merely elastic material such as ELGILOY may be used and plastically deformed in stages, possibly accompanied by annealing, to obtain the 3-D shape. Alternatively, a tubular blank could be formed to define a non-tubular shape, typically conical. A method for calculating the precise 2-D blank shape is also disclosed. A mandrel assembly includes a mandrel and ring elements for pressing the blank against the external surface of the mandrel prior to shape setting.

A minimally invasive catheter system and method for extraction of a shape memory device such as a nitinol stent from inside a tubular organ, is provided. The catheter system comprises a multi-lumen tube with at least one expandable balloon and an extraction device. The multi-lumen tube has multiple ports, which are used for injecting fluid inside the tubular organ and the expandable balloon, and inserting the extraction device. The catheter system is inserted inside the lumen of the tubular organ percutaneously. A cold fluid is injected into the expandable balloon and the lumen of the tubular organ. This cold fluid converts the shape memory device from an expanded state to a collapsed state. The shape memory device in the collapsed state is then removed with the help of the extraction device.

Elastomeric polymeric flosses comprising particulate modification agents stably associated with the surface thereof, as well as methods for their fabrication, are provided. In the subject flosses, particulate modification agents are either adsorbed to the surface of the floss or embedded in the surface of the floss. To fabricate the subject flosses, unmodified elastomeric flosses are contacted with particulate modification agents under conditions which provide for the stable association of the particles with the floss surface, where the floss surface may be softened to promote embedding of the particulate modification agents in the surface of the floss.
