Abstract: This invention is a surgical device. In particular, it is a catheter suitable for treating a tissue target within the body, which target is accessible through the vascular system. Central to the invention is the use of stiffener ribbons, typically metallic, wound within the catheter body in such a way as to create a catheter having controllable stiffness.

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. The proximal cage assembly may be used for collecting emboli or for displacing them to allow blood flow to resume, either with or without concurrent clot-dissolving drug treatment. The distal sector, whether a self-expanding cage or fan, is placed distally of the thrombus to collect portions of the thrombus which may loosen during the treatment or removal procedure.

The cage assembly may have a generally conical distal or "trailing" portion when expanded and also a proximal section. The cage assembly may be used for collecting emboli or for displacing them to allow blood flow to resume. The proximal section may have various uses, e.g., for centering the collector assembly in the vascular lumen or for gathering larger amounts of the targeted clot or to act as a passageway for fluid flow. The assembly further may have an actuator which permits or causes the collector assembly to expand after deployment.

Abstract: A method and system for treating a patient's heart exhibiting arrhythmia by first detecting electrical activity within the patient's heart to determine the location of the arrhythmogenic site or conductive pathway causing the arrhythmia and then creating an infarct within the region of the patient's heart where the arrhythmogenic site or the conductive pathway causing the arrhythmia is located by delivering an occluding element to a coronary artery which delivers oxygenated blood to said region of the patient's heart. In one presently preferred embodiment the occluding element is a flaccid or limp coil which when disposed in a coronary arterial passageway forms a randomly shaped, intertwined mass which quickly forms thrombus within the coronary artery to block the passage of oxygenated blood therethrough. The flaccid coil may be delivered through an inner lumen of a catheter which has a distal portion extending within the coronary artery.

Abstract: This is a composite guidewire for use in a catheter. It is used in medical procedures that involve accessing specifically targeted inner body areas without major surgery. The composite guidewire is especially useful for accessing peripheral soft tissue targets. The guidewire may be a multi-section guidewire assembly preferably having super-elastic alloy ribbon braided reinforcements along at least a portion of the core. The guidewire core may be of a stainless steel or a high elasticity metal alloy, preferably a Ni--Ti alloy. A variation of the guidewire also preferably includes a braid on the exterior of the core wire with an exterior polymeric coating to the most distal portion of the assembly and preferably assembled using adhesives such as epoxies.

Abstract: This invention is a surgical device. In particular, it 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 invention is the use of a stiffener ribbon, typically metallic, wound within the catheter body in such a way as to create a catheter having controllable stiffness. The stiffener ribbon is adhesively bonded to a flexible outer tubing member so to produce a thin wall catheter section which is exceptionally flexible but highly kink resistant. The catheter sections made according to this invention may be used in conjunction with other catheter sections either using the concepts shown herein or made in other ways. Because of the effective strength and ability to retain a generally kink-free form, these catheters may be effectively used in sizes which are quite fine, e.g., 0.015" to 0.020" in diameter, and useable within typical vascular catheters.

Abstract: This invention is a surgical instrument, and specifically is a device for delivering embolic coils to a selected site within the vasculature of a human body. This instrument uses, and may include, the catheter used to place the embolic coil. In particular, the device is made up of a pusher wire having a distal tip which is configured to engage the proximal end of an embolic coil. The device may also include a cylindrical pusher which coaxially surrounds at least a portion of the pusher wire and cooperates in the disengagement of the coil from the pusher wire and the ejection of the vasoocclusive coil into the selected vascular site. The pusher wire's engagement tip may be of any selected and convenient shape, and may be grooved, if so desired, to enhance the engagement joint strength.
