International Classification:

A61F002/06

US Classification:

623/001160

Abstract:

The method and apparatus described and illustrated herein generally relate to a bypass method to provide blood flow directly from a heart chamber, such as the left ventricle, and coronary vasculature, such as a coronary artery, and a conduit especially suited for placement in the myocardium to provide such flow. The conduit is particularly useful when a blockage partially or completely obstructs the coronary artery, in which case the conduit is positioned distal to the blockage. Aspects of the present invention relate to conduits in the form of stents that have particular configurations exhibiting properties suited to placement in the myocardium. Such a stent expands from a first diameter during delivery to a myocardial site to a second diameter when implanted in the site. The stent includes a configuration that has high radial strength to resist deformation from contractile forces experienced during a cardiac cycle. The configuration also exhibits high flexibility in a compressed state and a deployed state to permit passage to a myocardial site and remain patent when implanted in the site. The expandable stent may include suitable coverings and coatings.

International Classification:

A61F002/06

US Classification:

623/001110, 623/001340

Abstract:

A stent delivery system includes an inner tubular member on which a stent is loaded, an outer jacket extending over said inner tubular member, the retraction of which causes deployment of the stent, and a handle adapted to move the jacket relative to the inner tubular member. The constructions of the inner tubular member and outer jacket and the handle provide increased control of the relative movement of the outer jacket relative to the inner tubular member, and prevention of premature release of the stent from the deployment instrument, and greater control over stent deployment via visual and auditory feedback at the proximal end of the instrument, among other advantages.

US Classification:

12866003

Abstract:

A steerable guiding catheter having an ultrasound imaging distal tip for use in guiding an electrophysiology catheter. The guiding catheter includes a steering mechanism in order to steer the tip of the catheter so that the electrophysiology catheter may be steered to a desired location within the body of a patient.

International Classification:

US Classification:

607122

Abstract:

An electrically conductive sheath introducer is provided which functions as a unipolar electrode as well as a percutaneous vascular sheath introducer for a catheter. Typically, the catheter will include an electrode at its distal portion, and a circuit will be developed which includes the electrode of the catheter and the electrically conductive sheath introducer. Various electrical procedures are thus possible, including recording and energy delivery. The sheath introducer is rendered electrically conductive by ion process deposition treatment of the polymeric material sheath with a metallic material or materials. The resulting electrically conductive sheath introducer exhibits an incredibly low resistivity and resistance.

International Classification:

US Classification:

Abstract:

A guiding catheter, including a specialized guiding catheter referred to as a guiding sheath, has a uniquely curved three-dimensional distal end portion. This distal end portion has a two-dimensional turn of less than a full circle, which turn includes both an incomplete turn section and a distal extension thereof which is an end section. The turn lies in three dimensions and, when viewed in a direction which moves distally along the curve, curves upwardly and downwardly and again upwardly, each out of the plane within which the rest of the catheter lies. The guiding catheter or sheath is especially useful for guiding an electrophysiology catheter for facilitating ablation within the right atrium and/or ablation within the left atrium, such as by way of a transsceptal procedure.
