Abstract: The present disclosure provides poly(tetrafluoroethylene) (PTFE) microparticles with a Dv50 of about 20 ?m to about 30 ?m and a specific surface area (SSA) of at least about 3.0 m2/g when measured by a multipoint BET method of ISO 9277. Such PTFE microparticles can be obtained via a method including thermomechanically degrading scrap PTFE in the presence of air and/or oxygen and reducing the particle size of the resultant degraded PTFE.

Abstract: The present application relates generally to tubes, such as thin walled catheter liners with small wall thicknesses (e.g., less than 1 mm), including crosslinked fluoropolymers, e.g., crosslinked poly(tetrafluoroethylene). The disclosure further provides methods of manufacturing such tubes and systems for manufacturing such tubes.

Abstract: A non-crosslinked polymeric heat shrink tubing including poly(ether-block-amide) (PEBA) and methods for making such non-crosslinked polymeric heat shrink tubing is provided. The non-crosslinked PEBA heat shrink tubing disclosed herein finds application, e.g., as a processing aid and final component in the manufacture of catheters and other medical devices.

Abstract: A game piece tossing game having a first plurality of offensive game targets, where each of the offensive targets comprises a playing surface and a target aperture within the playing surface, a second plurality of defensive game targets, where each of the defensive targets comprises a playing surface and a target aperture within the playing surface, at least one game piece, arranged to be tossed toward the playing surface of at least one of the offensive game targets, and preferably arranged to be tossed toward the target aperture within the playing surface of the at least one of the offensive game targets, wherein the first plurality of offensive game targets are arranged on a playing field by a first team, and the second plurality of defensive game targets are arranged on a playing field by a second team. A method of play is also disclosed.

Abstract: A common issue when building a catheter with a laser-cut hypotube is bonding the OD (outer diameter) of the PTFE or PE liner to the ID (inner diameter) of an adjacent component, e.g., a laser-cut hypotube An expandable tie layer or “heat grow tie layer” as described herein can be used as a coating for the liner that will expand or foam up to the ID (inner diameter) of an adjacent component, e.g., hypotube and improve adhesion to the hypotube without impacting the flexibility or lubricity of the liner. This and other applications of the expandable layer are described herein.

Abstract: A non-crosslinked polymeric heat shrink tubing including poly(ether-block-amide) (PEBA) and methods for making such non-crosslinked polymeric heat shrink tubing is provided. The non-crosslinked PEBA heat shrink tubing disclosed herein finds application, e.g., as a processing aid and final component in the manufacture of catheters and other medical devices.

Abstract: The disclosure relates to assemblies of thin-walled tubes and mandrels for use in thin wall catheter liners. For example, an assembly is provided that includes a thin-walled PTFE tube comprising walls with a thickness of less than 0.004 inches, positioned over a filled mandrel comprising PTFE with one or more fillers incorporated therein. The disclosure further provides, independently, thin-walled tubes and filled mandrels, as well as methods of making and using such components.

Abstract: The disclosure generally relates to ultra high molecular weight poly (ethylene) (“UHMWPE”) tubes with an average wall thickness of 0.2 mm or less; a tensile stress at break greater than 40 MPa; and a storage modulus of greater than 500 MPa at 23° C. The disclosure further relates to preparing and using such tubes and to constructions (e.g., catheter constructions) and components thereof including such tubes.

Abstract: The disclosure provides coated tubings, including a layer of PEBA (or other polymer) on an etched polymeric tubing. The layer of PEBA (or other polymer) can have a low thickness, e.g., less than 1 micron and can provide for efficient bonding to an overlying jacket layer. The disclosure further provides methods of making and using such coated tubings.
