Embodiment Construction

[0036] exist Figure 1a and 1b An intravascular blood pump P inserted into a patient's heart H is shown in . More specifically, the blood pump P comprises a pumping device 1 attached to a catheter 5 through which the pumping device 1 is inserted into the left ventricle LV of the patient's heart H to pump blood from the left ventricle LV to the aorta AO. The shown application is only an exemplary application, and the blood pump P of the invention is not limited to this application. For example, a reverse application for the right ventricle RV can be envisioned. A blood pump P is inserted percutaneously, for example via a femoral access, and is propelled into the heart H via the aorta AO (see Figure 1a ). Alternatively, blood pump P can be inserted percutaneously via the axillary artery access and advanced into the heart H via the subclavian artery SA and the aorta AO (see Figure 1b ). The blood pump P is positioned such that the blood flow outlet 2 is located within the a...

Abstract

An intravascular blood pump (P) comprises a catheter (5) and a pumping device (1) attached to a distal end (15) of the catheter (5). The blood pump (P) is advanced through a patient's blood vessel by means of the catheter (5). The catheter (5) has an elongate tubular body (10) and a porous three-dimensional structure (6) provided on at least a portion of the outer surface (8) of the catheter body (10) to promote adsorption of proteins and formation of an autologous graft (7) to prevent the catheter (5) from growing into the inner wall of the blood vessel. The porous three-dimensional structure (6) may be formed as a textile sleeve (6), preferably made of a warp knitted fabric.

Description

technical field [0001] The present invention relates to an intravascular blood pump for percutaneous insertion into a patient's blood vessel, particularly to be advanced into a patient's heart, and more particularly to a catheter for an intravascular blood pump that reduces or avoids ingrowth into vascular tissue. Background technique [0002] Endovascular blood pumps designed for percutaneous insertion into a patient's blood vessel (such as the femoral or axillary artery or vein) can be advanced into the patient's heart for use as a left ventricular assist device or a right ventricular assist device. Therefore, the blood pump can also be called an intracardiac blood pump. An intravascular blood pump typically includes a catheter and a pumping device attached to the distal end of the catheter. The conduit may have an elongated body and may contain supply lines such as electrical and cleaning lines. The pumping device may include an impeller that rotates during operation of...
