摘要： A tube-in-tube assembled parison for preparation of an elongated medical device. The parison if formed by assembling in tube-in-tube fashion a first tube of orientable polymer material and a second tube formed of orientable polymer material disposed around the first tube, with an adhesive tie layer disposed between the first and second tubes. The tubes are brought into contact to form a unitary parison. The adhesive may allow movement between the polymer layers during balloon blowing. The first tube, or the second tube, or both, may have been longitudinally pre-stretched after formation thereof but before assembly of the parison.

摘要： An elongate polymer member (10) having molecular helical orientat ion formed by rotation immediately after passing through the extrusion head (20). The elongate polymer member (100) is rotated downstream of the extrusion head (20) in the molten state prior to solidification in order to impart the molecular helical orientation. Rotating the polymer member (100) in the molten state allows the helical orientation to be imparted at the molecular level, and allows for more rotations per lineal foot of extrusion.

摘要： A medical device, such as a catheter, catheter balloon, stent, blood filter, endoscope or portion thereof, comprises a segmented polymer, having a plurality of hard segments and a plurality of soft segments. The polymer hard segments have a substantially uniform molecular weight distribution. The molecular weight distribution ratio, Mw/Mn, may be 1.5 or less.

摘要： The present invention provides a polymeric treatment for curved regions in shaft assemblies that increases curve retention without affecting the flexibility within these regions. More specifically, the present invention modifies the underlying crystalline morphology of a polymer in order to decrease crystal fracturing. In particular, the present invention treats polymeric materials suitable for catheter construction with a nucleating agent.

摘要： Composite fiber reinforced balloons for medical devices prepared by applying a web of fibers to the exterior of a preformed underlying balloon and encasing the web with a matrix material to form a composite balloon. The fiber web is applied to at least the cone portion of the underlying balloon form. Either the cone portion of the underlying balloon form, or the web fibers applied to said cone portion, or both, have a friction-enhancing material coated thereon.
