Claims
- 1. A blood pump having an impeller comprising at least two vascular connection devices for a tubeless connection of the pump to a blood vessel outside the heart.
- 2. The blood pump of claim 1, wherein the tubeless connection devices are of the type selected from the group consisting of a suture ring and a vascular prosthesis.
- 3. The blood pump of claim 1, wherein the impeller is housed inside a pump housing and the connection devices are disposed at the housing.
- 4. The blood pump of claim 1, wherein the length of the pump housing is lass than twice that of its diameter.
- 5. The blood pump of claim 4, wherein the length is less than 1.5 times the diameter of the housing.
- 6. The blood pump of claim 1, wherein the length of each of the vascular connection devices is shorter than the diameter of the pump housing.
- 7. The blood pump of claim 3, further comprising a motor for driving the impeller and wherein webs are provided between an outer casing of the housing and the motor.
- 8. The blood pump of claim 8, wherein the webs are configured as vanes.
- 9. The blood pump of claim 7, wherein the motor is firmly held to the outer mantel of the housing by the webs.
- 10. The blood pump of claim 7, wherein the webs are configured for housing metal cables or metal pins for transmission of electric current.
- 11. The blood pump of claim 7, wherein an area bordered by the motor and the casing, is a flow area with a diameter which is 50% of a free flow area at one end of the pump housing.
- 12. The blood pump of claim, 11, wherein the diameter of the free flow area is at least 80% of the free flow diameter at the one end of the pump housing.
- 13. The blood pump of claim 3, wherein the pump is provided with two pump housings and two motors.
- 14. The blood pump of claim 14, further comprising an adaptable connection device between the two pump housings.
- 15. The blood pump of claim 14, wherein the impellers can be driven in opposite direction.
- 16. The blood pump of claim 3, further comprising an auxiliary motor disposed at the housing, said auxiliary motor provided with a mass driven in opposite direction to the impeller.
- 17. The blood pump of claim 3, wherein the housing is provided with an attachment device for attachment of the pump to tissue.
- 18. The blood pump of claim 17, wherein the attachment device is configured for attachment to a rib cage.
- 19. A method for a tubeless vascular implant of a blood pump with an impeller comprising the steps of providing a blood pump with connection devices, preparing vascular tissue for the implant, inserting the pump into location and connecting the pump directly to the vascular tissue with a connecting device selected from the group consisting of suture rings and vascular prosthesis.
- 20. The method of claim 19, wherein the pump connection devices are sutured to the vascular tissue.
