THRUST BEARING WITH LUMEN - A simplified explanation of the abstract
This abstract first appeared for US patent application 18639094 titled 'THRUST BEARING WITH LUMEN
Simplified Explanation: The patent application describes an apparatus with a blood pump that can be inserted into a subject's body over a guidewire for pumping blood.
- The apparatus includes an axial shaft with a shaft lumen for the guidewire to pass through.
- An impeller is attached to the axial shaft to pump blood as it rotates.
- A thrust bearing prevents excessive movement of the axial shaft and is shaped to be continuous with the shaft lumen.
- The bearing lumen is frustoconically-shaped, with a wider end facing distally.
Key Features and Innovation:
- Blood pump apparatus for insertion and rotation within a subject's body.
- Axial shaft with a shaft lumen for guidewire passage.
- Impeller for blood pumping.
- Thrust bearing to inhibit excessive axial shaft movement.
- Frustoconically-shaped bearing lumen.
Potential Applications:
- Medical devices for blood circulation support.
- Surgical procedures requiring blood pumping.
- Cardiac assist devices.
Problems Solved:
- Facilitates blood pumping within a subject's body.
- Prevents excessive axial shaft movement.
- Enables precise control during medical procedures.
Benefits:
- Improved blood circulation support.
- Enhanced surgical precision.
- Increased safety during medical interventions.
Commercial Applications: Blood Pump Apparatus for Medical Procedures: Enhancing surgical precision and safety in cardiac procedures.
Prior Art: Readers can explore prior patents related to blood pumps, axial shaft designs, and medical devices for blood circulation support.
Frequently Updated Research: Stay informed about the latest advancements in blood pump technology, medical device innovation, and surgical procedures for cardiac support.
Questions about Blood Pump Apparatus: 1. How does the frustoconically-shaped bearing lumen contribute to the functionality of the apparatus? 2. What are the potential implications of using this blood pump apparatus in minimally invasive surgical procedures?
Original Abstract Submitted
Apparatus and methods are described including a blood pump that includes an axial shaft configured for insertion, over a guidewire, into a subject's body, and for rotation within the subject's body. The axial shaft is shaped to define a shaft lumen for passage of the guidewire therethrough. An impeller is coupled to the axial shaft such that, as the axial shaft rotates, the impeller pumps blood of the subject. A thrust bearing is disposed distally from the axial shaft so as to inhibit distal movement of the axial shaft beyond the thrust bearing. The thrust bearing is shaped to define a bearing lumen that is configured to be continuous with the shaft lumen. At least a portion of the bearing lumen is frustoconically-shaped, a wider end of the frustoconically-shaped portion of the bearing lumen facing distally. Other applications are also described.
