The present invention relates to a shaft for a catheter which may be usable having a tubular core which may be usable with a minimally invasive procedure such as intravascular medical treatment system. It also relates to a method of fabricating such shaft. The shaft has a longitudinal axis defining a radial distance, and a cross section having a polar axis defining an angular position, wherein the shaft comprises a tubular core which has an inner perimeter and an outer perimeter, and an outer layer for improving mechanical properties, which encloses the tubular core such that the outer perimeter of the core and the outer layer face each other, wherein the radial distance between the outer perimeter and the inner perimeter differs at different polar angular positions, forming zones of different stiffness at different angular positions, wherein different planes of the shaft oriented along the longitudinal axis and cutting the cross section at different polar angular positions have different flexural properties which are determined by the stiffness of the zones.

Shaft for a catheter and fabrication method

An instrument for facilitating transseptal delivery of a cardiac therapeutic device is positionable in a left ventricle. The instrument includes an elongate shaft having a tubular lumen, the shaft having a proximal portion and a distal portion actively steerable between a generally straight position and a curved position. An external pull wire and an internal pull wire are each actuatable to move the distal portion to the curved position. The external pull wire extends internally through the proximal portion of the shaft and longitudinally along the exterior of the distal portion of the shaft, while the internal pull wire extends internally through the proximal portion of the shaft adjacent to the external pull wire, and extends internally through the distal portion of the shaft.

Instrument for facilitating transseptal delivery of cardiac therapeutic devices

A conduit for creating a passage from a right atrium to a left atrium, through a mitral valve into the left ventricle, and to provide a passage from the left ventricle into the aortic valve. The conduit includes an elongate tubular member having a shaft with a proximal section and a distal loop section at a distal end of the proximal section. The distal loop section includes a proximal curve, a distal curve, a generally straight segment extending between the curves, and a distal tip. The shaft in the distal loop section curves back on itself so that proximal curve is formed by a part of the shaft that is closer along the length of the shaft to the distal tip. The shapes of the proximal and distal curves are selected to direct the distal tip into the mitral valve after it has crossed the inter-atrial septum from the right atrium to the left atrium of the heart, and to orient the distal opening of the distal tip towards the aortic valve when the proximal curve is in the mitral valve and the distal tip is in the left ventricle.

Conduit for transseptal passage of devices to the aorta

A system and method used to deliver a percutaneous ventricular assist device (pVAD) or other cardiac therapeutic device to a site within the heart, such as a site at the aortic valve. A flexible device is percutaneously introduced into a vasculature of a patient and positioned to run from a femoral vein, through the heart via a transseptal puncture, and to a femoral artery. The venous-side end of the flexible device is withdrawn out the venous vasculature superior to the heart, and a pVAD is secured to the flexible device. The pVAD is pushed in a distal direction while the arterial-side end of the flexible device is pulled in the proximal direction to advance the pVAD to the target site. A left ventricle redirector aids in orienting the pVAD and preventing migration of the flexible member towards delicate structures of the heart during advancement of the pVAD.
