Abstract

Apparatus and methods are described including manufacturing a housing for an impeller of a blood pump by placing an inner lining around a mandrel, placing a cylindrical portion of a frame around the inner lining, and placing a distal portion of an elongate tube around a portion of the frame. While the distal portion of the elongate tube is disposed around the portion of the frame, the inner lining, the frame, and the distal portion of the elongate tube are heated, via the mandrel, and pressure is applied from outside the distal portion of the elongate tube, such as to cause the distal portion of the elongate tube to conform with a structure of the struts of the frame, and to cause the inner lining and the distal portion of the elongate tube to become coupled to the frame. Other applications are also described.

Dependent claims

A method, comprising:

manufacturing a housing for an impeller of a blood pump by:
placing an inner lining around a mandrel;
placing a cylindrical portion of a frame around the inner lining, the cylindrical portion of the frame including struts that define a generally cylindrical shape;
placing a distal portion of an elongate tube around at least a portion of the frame, the elongate tube including a proximal portion that defines at least one blood outlet opening;
while the distal portion of the elongate tube is disposed around at least the portion of the frame, heating the inner lining, the frame and the distal portion of the elongate tube, via the mandrel;
and
while heating the inner lining, the frame, and the distal portion of the elongate tube, applying pressure from outside the distal portion of the elongate tube, such as to cause the distal portion of the elongate tube to conform with a structure of the struts of the frame, and such as to cause the inner lining and the distal portion of the elongate tube to become coupled to the frame.
