VENTRICULAR ASSIST DEVICE FOR INTRAVENTRICULAR PLACEMENT

Номер: US20170165408A1
Принадлежит:

A ventricular assist device includes a pump such as an axial flow pump, an outflow cannula connected to the outlet of the pump, and an anchor element. The anchor element is physically connected to the pump, as by an elongated element. The pump is implanted within the left ventricle with the outflow cannula projecting through the aortic valve but desirably terminating short of the aortic arch. The anchor element is fixed to the wall of the heart near the apex of the heart so that the anchor element holds the pump and outflow cannula in position. 1. (canceled)2. A blood pump for intraventricular placement inside a heart of a mammalian subject comprising:a rigid elongate member defining a major longitudinal axis having a length between proximal and distal ends and a bore extending along the length;an anchor element connected proximate the proximal end of the rigid elongate member and mountable to the subject's heart; anda pump defining a pump axis and including an inlet at a first end and an outlet at a second end, the inlet and outlet being positioned along the pump axis, a rotor defining a rotor axis coincident with the pump axis and including at least one electric drive coil spaced laterally from the pump axis and the rotor axis for magnetically driving the rotor, the pump being coupled proximate the distal end of the rigid elongate member and remote from the anchor element, the rotor axis and the pump axis being offset from the member axis.3. The pump of claim 2 , further comprising wire extending through the bore of the pump claim 2 , and wherein the proximal end of the rigid elongate member includes a fitting through which the wiring passes into the bore of the rigid elongate member.4. The pump of claim 3 , wherein the wiring extends from a source of electrical power claim 3 , through the fitting of the rigid elongate member claim 3 , through the bore of the rigid elongate member claim 3 , and to the at least one electric drive coil to drive the rotor of the pump ...

The present invention includes various devices and methods for ventricular assist. In one embodiment, the present invention is a ventricular assist device for intraventricular placement inside a heart of a mammalian subject, the device including a ring configured to be mounted adjacent an apex of the patient's heart; a rigid elongate member having a proximal and distal end; and a pump having a housing and an outflow cannula having a tip, the tip having a distal end projecting through an aortic valve of the subject's heart, wherein the ring and the pump are connected to the rigid elongate member remote from one another so that the rigid elongate member maintains the pump in position relative to the ring. 1. A ventricular assist device for intraventricular placement inside a heart of a mammalian subject comprising:a ring configured to be mounted adjacent an apex of the patient's heart;a rigid elongate member having a proximal and distal end; anda pump comprising:a housing and an outflow cannula having a tip, the tip having a distal end projecting through an aortic valve of the subject's heart,wherein the ring and the pump are connected to the rigid elongate member remote from one another so that the rigid elongate member maintains the pump in position relative to the ring.2. The ventricular assist device of claim 1 , wherein the tip terminates short of an arch of the aorta of the subject's heart.3. A method of installing a ventricular assist device in a mammalian subject comprising:(a) mounting a pump to the subject so that an inlet of the pump communicates with the left ventricle of the heart; and(b) positioning an outflow cannula of the pump so that the outflow cannula extends from within the left ventricle through the aortic valve but terminates short of the arch of the aorta.4. A method as claimed in wherein the step of mounting a pump to the subject includes mounting the pump within the left ventricle of the heart.5. A method as claimed in further comprising the ...
