Patent number: 6599308Abstract: The present invention provides a method of forming a medical device and medical devices which can be formed in accordance with the method. In one embodiment, the method includes the steps of a) providing a metal fabric formed of a plurality of strands formed of a metal which can be heat treated to substantially set a desired shape; b) deforming the metal fabric to generally conform to a surface of a molding element; c) heat treating the metal fabric in contact with the surface of the molding element to substantially set the shape of the fabric in its deformed state; and d) removing the metal fabric from contact with the molding element. The resulting metal fabric will define a medical device which can be collapsed for passage through a catheter or the like for deployment in a channel of a patient's body. Medical devices made in accordance with this method can have varying structures.Type: GrantFiled: February 1, 2002Date of Patent: July 29, 2003Assignee: AGA Medical CorporationInventor: Curtis Amplatz

Patent number: 5964751Abstract: A light delivery system for use in irradiating vascular tissue includes a balloon catheter with a working lumen for receiving an optical fiber therein and an inflation/flushing lumen adapted to receive a liquid at a proximal end and leading to a space defined within the balloon member attached to a distal end of the catheter. The balloon member has a pattern of holes or pores in the wall thereof through which the saline may flow when the balloon is inflated, causing any blood or other absorbing substances that may interfere with good radiant energy transmission to be flushed away from the treatment site.Type: GrantFiled: August 25, 1998Date of Patent: October 12, 1999Assignee: Illumenex CorporationInventors: Curtis A. Amplatz, Mark A. Rydell, Robert J. Ziebol, Christopher H. Porter, Michael Kasinkas

Patent number: 5620438Abstract: A surgical instrument for treating a blood vessel wall following percutaneous transluminal coronary angioplasty (PTCA) includes an optical system for transmitting radiant energy, preferably UV light energy, from a laser source to the distal end portion a PTCA catheter and causing the radiant energy to exit the catheter in a relatively narrow radial band. A microprocessor-controlled stepping motor is used to longitudinally reposition the band along the length of the balloon of the PTCA catheter to thereby expose endothelial tissue spanned by the balloon to radiation for the purpose of inhibiting smooth muscle proliferation reducing incidences of restenosis.Type: GrantFiled: April 20, 1995Date of Patent: April 15, 1997Assignee: AngioMedics II IncorporatedInventors: Curtis A. Amplatz, Christopher H. Porter, Mark A. Rydell

Patent number: 5607419Abstract: Disclosed is an apparatus for use in applying UV light to a blood vessel wall following the performance of a balloon angioplasty procedure. It comprises an elongated optical fiber whose outside diameter permits it to be inserted into the lumen of a guidewire that is used to position the angioplasty balloon at the site of the lesion to be treated. The guidewire is provided with a light port and a suitable reflector is provided for causing UV light transmitted through the optical fiber to be radiated in a radial direction through the light port in the guidewire to thereby irradiate the vessel wall with UV energy that has been found effective in retarding growth of smooth muscle cells.Type: GrantFiled: April 24, 1995Date of Patent: March 4, 1997Assignee: AngioMedics II Inc.Inventors: Curtis A.
