Micrograft for the treatment of intracranial aneurysms and method for use
A device for occluding a vasculature of a patient including a micrograft having an absorbent polymeric structure with a lumen of transporting blood. The micrograft has a series of peaks and valleys formed by crimping. The occluding device is sufficiently small and flexible to be tracked on a guidewire and/or pushed through a microcatheter to a site within the vasculature of the patient. Delivery systems for delivering the micrografts are also disclosed.

Installations for manufacturing biaxially oriented tubing and the tubing itself
The production of a biaxially oriented tube from thermoplastic material, wherein a tube in preform condition is extruded from thermoplastic material using an extruder having an extruder die head with an inner die member that forms a lumen in the tube in preform condition. The tube in preform condition is subjected to a temperature conditioning. Use is made of a expansion device comprising a non-deformable expansion part having a gradually increasing diameter to a maximum diameter, which expansion part is contacted by the tube and exerts an expanding force so as to bring about expansion of the tempered tube in circumferential direction. The method comprises drawing the tempered tube over the expansion device using a drawing device, in such a manner that said tube is transformed from a tube in preform condition into a biaxially oriented tube with thermoplastic material which is oriented in axial direction and in circumferential direction of the tube.
Lubricious extruded medical tubing
A medical tube having improved lubricity is disclosed. The medical tube is produced by extruding a polymer material blended with a lubricity enhancing additive through a resilient die. The polymer material can be medical-grade high-density polyethylene, and the lubricity enhancing additive can be a silicone-based or alloy-based material. The medical tube can include one or more internal elongated protuberances so as to reduce the internal surface area of the medical tube available to generate friction on a guide wire inserted or withdrawn through the medical tube.

Method for manufacturing a connector
A method and apparatus for manufacturing a connector for a container for medical use intended to administer fluid, the connector including a main body defining an inner channel for fluid to pass through and at least one continuous or discontinuous bead, projecting inside the channel. The method includes: a) producing a tubular conduit with no bead projecting inside the channel, b) inserting at least partially into the tubular conduit a mandrel having, on its outer surface, at least one continuous or discontinuous annular recess, whose dimensions and shape correspond to those of a continuous or discontinuous bead to be formed in the inner channel, c) partially heating the tubular conduit, the part including at least the conduit portion placed at the at least one recess when the mandrel has been positioned in the tubular conduit, such that the material of the tubular conduit fills the at least one recess.
Molded article and manufacturing method for same
The purpose of the present invention is to provide a molded article and a manufacturing method for a molded article by which it is possible to mitigate deformation of an opening. The present invention provides a molded article comprising a cylindrical base and an opening provided in the base, wherein a rib is provided adjacent to the opening. The present invention provides a manufacturing method for a molded article that includes a molded body formation step for forming a molded body having a cylindrical portion provided at one end thereof with an occlusion by molding a melted resin, and a cut-off step for cutting off the occlusion by cutting the cylindrical portion, wherein in the cut-off step, the cutting is performed in a state where a side wall of the cylindrical portion is warped in-plane by an external force.
Continuous Micro-irrigation Tubing and its Making Method, Using Method, and Application
The embodiments of the present application provide a method for making continuous micro-irrigation tubing, the continuous micro-irrigation tubing so made, a method for performing irrigation using the said continuous micro-irrigation tubing, and the application of the said continuous micro-irrigation tubing in agricultural irrigation, wherein the method for making continuous micro-irrigation tubing comprises: preconditioning a filler; blending the preconditioned filler with high-pressure polyethylene resin at a predefined weight ratio and making said filler and resin into filler pellet; making preformed tubing from the filler pellet; and threading the preformed tubing into a high-temperature extractor in which continuous extraction is performed to make continuous micro-irrigation tubing. The method enables the making of continuous micro-irrigation tubing containing micro-pores on the tubing wall. After the continuous micro-irrigation tubing is filled with water, water exudes through the micro-pores.

Apparatus and methods for making coated liners and tubular devices including such liners
Apparatus and methods are provided for making coated liners and/or tubular devices including such coated liners. A sleeve may be provided that includes an outer first surface and an inner second surface extending between first and second ends thereof, and a hydrophilic or other coating may be applied to the first. The coated sleeve may be cut between the first and second ends to create opposing edges extending between the first and second ends, and the cut sleeve may be reversed such that the coated first surface defines an inner surface and the opposing edges are disposed adjacent one another, thereby providing a coated liner. Optionally, a tubular structure, e.g., one or more reinforcing layers and/or or outer layers may be attached around the coated liner, thereby providing a tubular device including an inner surface with a desired coating.
