A surgical method and apparatus for positioning a diagnostic or therapeutic element within the body. The apparatus may be catheter-based or a probe including a relatively short shaft.

Surgical method and apparatus for positioning a diagnostic or therapeutic element within the body

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. The catheter sections made according to this invention may be used alone or in conjunction with other catheter sections either made using the concepts shown herein or made in other ways. The more proximal sections of the catheter assembly are often substantially stiffer than the more distal sections due to the presence of stiff polymeric tubing or metallic tubing or composited materials in the stiffer section.

High performance braided catheter

A probe that facilitates the creation of circumferential lesions in bodily tissue. The probe includes a relatively short shaft and a loop-like structure that supports electrodes or other operative elements against the bodily tissue.

A surgical device including a relatively short shaft, a bendable spline assembly associated with the distal end of the shaft and having a predetermined configuration, the spline assembly being adapted to collapse in response to an application of an external force and to expand to the predetermined configuration in response to a withdrawal of the external force, and an operative element associated with the bendable spline assembly.

This is a composite guidewire for use in a catheter and is used for accessing a targeted site in a lumen system of a patient's body. The guidewire core or guidewire section may be of a stainless steel or a high elasticity metal alloy, preferably a Ni--Ti alloy, also preferably having specified physical parameters. The composite guidewire assembly is especially useful for accessing peripheral or soft tissue targets. Variations include multi-section guidewire assemblies having (at least) super-elastic distal portions and super-elastic braided reinforcements along the mid or distal sections. A variation of the inventive guidewire includes the coating of the wire with a tie layer and then with a one or more lubricious polymers to enhance its suitability for use within catheters and with the interior of vascular lumen.

A thrombogenic occlusion coil for occluding a blood vessel comprising a helical metallic coil having a plurality of axially spaced windings and a plurality of strands of a thrombogenic polymer extending axially through the central core of the coil, the ends of the strands being bound together.

Bioactive occlusion coil

This invention is an apparatus for endovascular occlusion through the formation of thrombi in arteries, veins, aneurysms, vascular malformations, and arteriovenous fistulas. In particular, it deals with an improved sacrificial link between an endovascular device which is introduced to and is intended to remain at the desired thrombus formation site and the device used to introduce the device. The invention further includes a method for introduction of the device and its electrolytic separation.

Electrolytically severable joint for endovascular embolic devices

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 a multi-component distal section having an interior stiffener and an exterior tubing member.
