Publication number: 20130317536Abstract: The method for making a reinforced balloon for a balloon catheter involves blending a polymer with a nano composite to form a composite matrix, extruding a parison from the composite matrix, blow molding the parison into a balloon and orienting the nano composite generally axially with respect to the balloon. The balloon formed has a high strength for resisting bursting. The nano composite may be carbon nanotubes, nano-ceramic fibers or a nano clay.Type: ApplicationFiled: August 5, 2013Publication date: November 28, 2013Applicant: MICRUS DESIGN TECHNOLOGY, INC.Inventor: Oscar Jimenez

Publication number: 20130131641Abstract: The intravascular catheter has two segments; a proximal segment with high stiffness and a distal segment with lower stiffness. The catheter can also have an intermediate segment of lower stiffness than the proximal segment and higher stiffness than the distal segment. The catheter comprises a polymeric inner tube, a reinforcing inner jacket which is spirally wound over the inner tube and which becomes progressively softer from a proximal end to a distal end, and a polymeric outer sheath extruded over the inner jacket according to the teachings of U.S. Pat. No. 5,445,624. The reinforcing jacket comprises helical coiled wires or fibers of various materials and layers wound over the inner tube in order to provide improved multi-axial mechanical properties, such as torque, compression, tension and anti-kinking characteristics.Type: ApplicationFiled: January 10, 2013Publication date: May 23, 2013Applicant: MICRUS DESIGN TECHNOLOGY, INC.Inventor: MICRUS DESIGN TECHNOLOGY, INC.
