A tubular catheter support member comprises a plurality of annular segments stacked along a longitudinal axis of the catheter, and a plurality of beams connecting respective annular segments in the stack, wherein the beams meet the respective annular segments at oblique angles, and wherein the beams collectively form a helix around the longitudinal axis of the catheter.

Balloon catheter and method of manufacture

Implantable medical endoprosthesis delivery systems and articles are provided.

Implantable medical endoprosthesis delivery system

A single lumen balloon-tipped micro catheter, wherein the distal portion of the shaft is reinforced and extends into the balloon to eliminate abrupt transitions in stiffness in the balloon region. The balloon may be formed of a thermoplastic polyisoprene rubber such as hydrogenated polyisoprene which has superior performance and manufacturing attributes.

Single lumen balloon-tipped micro catheter with reinforced shaft

The present invention relates to a high pressure vascular balloon catheter wherein the walls of the tube attached to the balloon-forming segment are reinforced with a braided ribbon member. The walls of the inner tube that provides the lumen for a guidewire may also be reinforced in the same way. The reinforcement has the dual effect of providing strength against rupture under pressure and prevention of ovalizing or kinking during insertion into tortuous vessels of a vascular system.

A solderless sacrificial link between a detachable member which is placed at and is intended to remain at a desired site within the mammalian body and the core wire used to introduce the detachable member. The detachable member device may be one used to create emboli in the vascular system or may be of any other type deliverable into the human body and detached into an ionic aqueous environment, either for later removal or permanent placement.

This is an artificial occlusion kit for implanting and retaining an artificial occlusion device in a body space adjacent to and extending from a body lumen in a mammal. The includes at least one occlusion device and a retaining device for blocking the migration of the occlusion device out of the occlusion site. The retaining device is radially expandable at a retaining site adjacent the body space to be occluded to a diameter that is sufficient to engage the body lumen wall at the retaining site and form a barrier across the entrance zone of the body space to be occluded. The expanded retaining device also forms a lumen for flow through body lumen at the retaining site. At least one semi-penetrable space may also be provided in the retaining device, allowing introduction of occlusion devices into the body space to be occluded, but preventing subsequent migration of the occlusion devices out of the body space. This semi-penetrable space may also be distensible to allow for delivery of occlusion devices therethrough. An introducer wire or a tapered-tip delivery catheter may be used to distend the distensible space and deliver the occlusion devices. The retaining device structure may further include a radiopaque metal wire wound into a primary helix over an inner core member made of a superelastic alloy of nickel and titanium. An implantable medical device assembly is also provided, having the structure described for the retaining device of the novel artificial occlusion kit, and which is attached to an elongate pusher via a sacrificial link that is electrolytically dissolvable.

Aneurysm closure device assembly

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. The outer tubing assembly allows the profile of the catheter to be minimized and yet provides significant kink-resistance to the inner tubing assembly. The structure of the inner tubing assembly provides resistance to premature inflation during introduction of infusate through the inner lumen.

This is a micro-vaso-occlusive device intended generally for occlusion of small arteries located distally in the vasculature. The device is made up of a binder, often radio-opaque, which may be short in length by comparison to the length of the included thrombogenic fibers. The fibers form the other portion of the device. At least one end of the device includes a solid but comparatively soft end typically made of a molten mass of the fibers. The micro device may have multiple binder sections. The fibers may be straight, looped, or tufted.

Soft-ended fibered micro vaso-occlusive devices

This is a vasoocclusive device which, as used, is in the approximate shape of an anatomical cavity. It may be deployed as a sphere, an ovoid, or other distorted spherical shape. The device is a self-forming shape made from a pre-formed vasoocclusion member. Prior to deployment, the vasoocclusive device is sufficiently straight that it is able to be pushed from a vascular catheter without excessive friction. The vasoocclusion member may be a small helical coil or braid variously comprising a suitable metal, or, in the case of a braid, such metal may be co-woven with various polymeric or natural fibers. Fibers may be introduced onto the device and affixed to the member. The constituent member may be also be covered with a fibrous braid. The device is typically introduced through a catheter. The device is passed axially through the catheter sheath and assumes its form upon exiting the catheter without further action. The invention also includes methods of winding the anatomically shaped vasoocclusive device into appropriately shaped forms and annealing them to form various devices.
