INTRAVASCULAR BLOOD PUMP WITH INTAKE FILTER - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240017051 titled 'INTRAVASCULAR BLOOD PUMP WITH INTAKE FILTER
Simplified Explanation
The abstract describes an intravascular blood pump with an intake filter that reduces the risk of heart tissue being sucked into the pump. The filter has multiple apertures through which blood flows, and these apertures are sized to prevent the ingestion of heart tissue. The filter consists of helical first struts wound around a longitudinal axis, along with second struts. The combination of first and second struts creates the apertures. The struts can be woven filaments or defined in a thin film tube, with the remaining material forming the struts.
- The intravascular blood pump has an intake filter that prevents heart tissue from being sucked into the pump.
- The filter has multiple apertures through which blood flows.
- The apertures are sized to prevent the ingestion of heart tissue.
- The filter is made up of helical first struts wound around a longitudinal axis.
- Second struts are also present and collectively define the apertures.
- The struts can be woven filaments or defined in a thin film tube.
Potential Applications
- Cardiac assist devices
- Extracorporeal membrane oxygenation (ECMO) systems
- Ventricular assist devices (VADs)
- Artificial hearts
Problems Solved
- Reduces the risk of heart tissue being sucked into the pump
- Prevents damage to the heart tissue during blood circulation
Benefits
- Improved safety and reliability of intravascular blood pumps
- Minimizes the risk of complications during cardiac procedures
- Enhances the effectiveness of cardiac assist devices
Original Abstract Submitted
an intravascular blood pump has an intake filter that reduces risk of heart tissue being sucked into an intake port of the pump. the filter defines a plurality of apertures, through which blood flows through the filter. the apertures are sized to prevent ingestion, by the input port, of the heart tissue. the filter includes a plurality of generally helical first struts wound about a longitudinal axis of the filter, and a plurality of second struts. the first and second struts collectively define the plurality of apertures therebetween. the struts may be woven filaments, or the apertures may be defined in a thin film (foil) tube, where remaining material between the apertures form the struts.
