A system and method verify a user's identity in an Internet-related transaction. One system and method use a personal computer having identification information, a card reader, and a personal identification card having access information, to verify a user's identity using the access information and the identification information. Another system and method use a personal computer, a card reader, and a personal identification card having access information, wherein the card reader is included as part of a mouse coupled to the personal computer and wherein a user's identity is verified using the access information. Another system and method use a personal computer, a device coupled to the personal computer having identification information, a card reader, and a personal identification card having access information to verify a user's identity using the access information and the identification information. Another system and method use a personal computer, a fingerprint reader, a card reader, and a personal identification card having access information to verify a user's identity using the access information and the data of the fingerprint reader.

System and method for identity verification

An improved method and devices for preventing restenosis are provided. The method may include delivering a stent configured to contain a stenosis to a body vessel. The method may also include using atherectomy at the site prior to stent delivery. In one embodiment, the stent has a proximal end, a distal end, and a center portion arranged such that the diameters of the proximal and distal ends are greater than the diameter of the center portion. In one embodiment, the atherectomy device includes a housing to prevent injury to the unaffected areas of the body vessels but the cutter is extendible beyond the housing. In one embodiment, the stent may be impregnated with at least one drug after stent deployment.

A method of inhibiting restenosis is disclosed. The method includes reducing contaminants during manufacturing of angioplasty devices and during angioplasty procedures. An angioplasty device is preferably examined for contaminants prior to the angioplasty procedure, and the contaminants are reduce if present.

Method of inhibiting restenosis

The method of vascular treatment for restenosis or vulnerable plaque after an invasive procedure, such as for example angioplasty, stenting with or without drug coating, or drug delivery, comprises: inserting a catheter or hollow guide wire to the treatment location; delivering light through the catheter in the wavelength range of about 700&#x2013;2500 nm; and moving the light to treat the affected region.

Electromagnetic photonic catheter for reducing restenosis

A low profile wire perfusion catheter is disclosed for use in percutaneous transluminal coronary angioplasty. The catheter includes a wire configured to be inserted into a blood vessel. The wire is hollow and defines an axial lumen therein. An inflation balloon is attached directly to the wire and is configured to expand radially outward in response to inflation thereof. Inflow and outflow perfusion ports extend through the wire and communicate with the lumen to allow perfusion of blood across the balloon when the balloon is inflated within a blood vessel. Because the balloon is attached directly to the wire, the catheter has an advantageously low cross-sectional area.

Wire perfusion catheter

Multi-lobe perfusion balloon

Disclosed is a light angioplasty catheter and method for exposing the interior of a body lumen to a source of light. Light exposure may be accomplished prior to, during, or following conventional balloon dilatation. Also disclosed is a method and apparatus for exposing a preselected portion of vessel wall to a source of light. Relatively low energy light exposure has been found by the inventors herein to both inhibit restenosis following dilatation of a stenotic region, and to inhibit vascular spasms whether or not associated with a stenotic region. It may also arrest progress of a stenosis. Methods are also disclosed for cooling the vascular wall to treat a stenosis. Cooling may be accomplished prior to, during, or following dilatation.

Method for minimizing restenosis

Apparatus for minimizing restenosis

Dilatation catheters for use in administering treatments to relieve stenotic regions within a body lumen while maintaining blood flow past the dilatation balloons are described. According to the present invention, perfusion ports are provided in both a guidewire lumen and in a bypass lumen in several alternative embodiments in order to provide increased blood flow past the dilatation balloon.

Blood perfusion balloon catheter

Dilatation catheters for use in administering treatments to relieve stenotic regions within a body lumen are described. In one aspect of the invention, a two wire catheter system, of minimal diameter for treating distal arteries is disclosed. In another aspect of the invention, a multiple wire multiple balloon system in disclosed, in which a first balloon on a first catheter is disposed distally of a second balloon on a second associated catheter. Additional balloons and associated catheters may also be incorporated into the multiple wire multiple balloon system. Methods are also discussed for accomplishing sequential dilatations using a multiple wire multiple balloon catheter.

Multi-wire multi-balloon catheter

Dilatation catheters for use in administering treatments to relieve stenotic regions within a body lumen are described. In one aspect of the invention, a two wire catheter system, of minimal diameter for treating distal arteries is disclosed, In addition, a number of various dilatation balloon configurations, for treating stenotic areas which are present in tortuous vessels, as well as hardened, or calcified stenotic portions are also described. Finally, a catheter system which provides a path for conducting blood past the stenosis and inflated dilatation balloon is discussed.
