Abstract
A mechanical circulatory support system may include a blood pump and an elongate shaft coupled to the blood pump. The blood pump may be configured to extend into a ventricle of a heart of a patient. The elongate shaft may be configured to be pulled through an aorta of the patient and into an axillary artery of the patient while the blood pump is in the heart of the patient. The blood pump may be a large-bore blood pump. The elongate shaft may be detachable from the blood pump. The elongate shaft extending through the axillary artery of the patient may be coupled with a controller configured to operate the blood pump while the patient is ambulatory.
Claims20
A mechanical circulatory support system comprising:
- a blood pump configured to extend into a ventricle of a heart of a patient;
- and
- an elongate shaft coupled to the blood pump and configured to be pulled through an aorta of the patient and into an axillary artery of the patient while the blood pump is in the heart of the patient.
A method comprising:
- inserting a pump to a heart of a patient through a femoral artery access site using a delivery sheath;
- removing the delivery sheath from an elongate shaft extending from the pump while leaving the pump in place;
- accessing the elongate shaft of the pump via an axillary artery of the patient;
- and
- coupling the elongate shaft with a controller.
A method comprising:
- operating a large-bore blood pump extending into a heart of a patient via an elongate shaft coupled with the large-bore blood pump and extending through an axillary artery of the patient;
- and
- removing the large-bore blood pump from the patient via a femoral artery access site.
