  • Patent number: 8486104
    Abstract: This is a surgical device usually delivered through an intravascular catheter. It may be used in several ways. It may, for instance, be used to open a clear passageway adjacent thrombus to allow both blood and medication to bypass the clot. It may be used to pierce and to remove thrombus. These thrombus are often found in tortuous vasculature. The device includes several sections. The device has a core element, typically a core wire. Placed around the distal end of the core element is a collapsible but preferably self expanding proximal cage assembly and a distal filter, preferably a self-expanding cage assembly or other filter component. The various portions of those components are preferably radio-opaque. The proximal end of the proximal cage is typically is affixed to an actuator in such a way as to allow expansion of the cage after deployment.

  • Patent number: 6824553
    Abstract: This is a catheter assembly and a section of that catheter assembly. That catheter assembly may be used in accessing a tissue target within the body, typically a target which is accessible through the vascular system. Central to the invention is the use of a braided metallic reinforcing member, typically of super-elastic alloy ribbon, situated within the catheter body in such a way to create a catheter having an exceptionally thin wall, controlled stiffness, high resistance to kinking, and complete recovery in vivo from kinking situations. The braid may have a single pitch or may vary in pitch along the axis of the catheter or catheter section. The braided ribbon reinforcing member typically is placed between a flexible outer tubing member and an inner tubing member to produce a catheter section which is very flexible but highly kink resistant.

  • Patent number: 6383205
    Abstract: A surgical device for opening a passageway adjacent a thrombus to allow both blood and medication to bypass a clot. The surgical device may also be used to pierce and remove a thrombus. The device includes a core element or wire having an expanding proximal cage assembly and a distal filter or expanding cage assembly placed around the core wire. Components of the device are preferably radio-opaque. The proximal end of the proximal cage may be affixed to an actuator to allow expansion of the cage after deployment. The proximal cage assembly may be used for collecting emboli or for displacing emboli to allow blood flow to resume, either with or without concurrent clot-dissolving drug treatment. The distal section is placed distally of the thrombus to collect portions of the thrombus which may loosen during the treatment or removal procedure.

  • Patent number: 6315757
    Abstract: This is a balloon catheter having braided layer which extends generally from the proximal end of the catheter to a location distal of the balloon. In particular, it is desirable that the shaft of the catheter proximal of the balloon be stiffest at the proximal section and least stiff just proximal of the balloon. Although the catheter may be a single lumen catheter using some type of a core wire to act as a valve for inflation and deflation of the balloon, it is within the scope of the invention to include either a separate inflation/deflation lumen or one incorporated into the various concentric polymeric layers used to make up the proximal shaft. Particularly preferred is the use of an elastic, compliant balloon.

  • Patent number: 6197014
    Abstract: This is a catheter section having a number of radially placed holes through the catheter section wall and a catheter assembly including that section. That catheter assembly may be used in accessing and treating a tissue target within the body, typically one which is accessible through the vascular system. Central to the catheter section is the presence of a braided metallic reinforcing member, typically of super-elastic alloy ribbon, situated in such a way to provide an exceptionally thin wall, controlled stiffness, high resistance to kinking, and complete recovery in vivo from kinking situations. The orifices in the section are optimally placed in the interstices between the turns of the braid. The braid may have a single pitch or may vary in pitch along the axis of the catheter or catheter section. The braided ribbon reinforcing member typically is placed between a flexible outer tubing member and an inner tubing member to produce a catheter section which is very flexible but highly kink resistant.

  • Patent number: 6186978
    Abstract: This is a surgical device particularly a perfusion catheter having an inflatable membrane or balloon located at the distal end of the catheter shaft. The catheter shaft is comprised of an outer tubing assembly and an inner tubing assembly separated by an open annulus for inflating and deflating the inflatable membrane. The assembly may additionally comprise an inflatable membrane which is detachable. The outer tubing assembly is made up of at least one polymeric layer and a braid which may be polymeric or metallic, perhaps of a super-elastic alloy. At least a portion of the inner tubing assembly is made up of at least one polymeric layer and preferably a super-elastic metallic braid. The inner tubing assembly includes a lumen through which a guidewire may pass. It is further desirable that the inner tubing assembly include a coil member which generally is coextensive with the balloon along its axis. That lumen is preferably lined with a lubricious polymer.

  • Patent number: 6152912
    Abstract: This is a catheter suitable for accessing a tissue target within the body, typically a target which is accessible through the vascular system. Central to the concept of the catheter is the use of a reinforcing member wound within the catheter body in such a way to create a catheter having an exceptionally thin wall, excellent kink-resistance, and controlled stiffness. The catheter assembly desirably is constructed of: (a) an inner, polymeric, lubricious liner, (b) a first, helically wound coil over at least the more distal portions of the inner liner, (c) a second, helically wound coil exterior to the first coil located at least on the more proximal portion of the assembly, and (d) one or more outer polymeric coverings exterior to the second coil. Further polymeric layers may also be placed between the outer polymeric covering and the helically wound coils. The outer polymeric covering may be composed of a series of different polymeric compositions to provide suitably differing flexibilities to the assembly.

  • Patent number: 6120499
    Abstract: The invention is directed to an intravascular device for occluding a patient's blood vessel by coagulating blood in a desired location within the blood vessel to form occluding thrombus therein by means of RF electrical energy which preferably has a frequency of about 0.3 to about 1.5 megahertz. The intravascular device is particularly useful in terminating arrhythmia in a patient's heart by occluding a coronary artery to terminate the flow of oxygenated blood to a region of the patient's heart where aberrant signals causing the arrhythmia either originate or through which they are conducted. The device may also be used to occlude other blood vessels such as in the treatment of intracranial berry aneurysms.
