[Heart assist systems with integrated microsensors (HIM 2)].

Area of Science:

• Biomedical Engineering
• Medical Device Technology
• Cardiovascular Support Systems

Context:

• Current intracardiac pump systems offer physiological support for coronary surgery but lack transfemoral suitability due to size.
• Existing 6.5 mm micro blood pumps with integrated sensors are too large for transfemoral device placement.

Purpose:

• To develop and test a significantly smaller intracardiac pump (4 mm outer diameter) suitable for transfemoral placement.
• To apply Moulded Interconnected Device (MID) technology for the first time in a medical device to integrate a miniaturized pressure sensor.

Summary:

• A novel 4 mm (12F) intracardiac pump is being developed, incorporating a miniaturized pressure sensor using Moulded Interconnected Device (MID) technology.
• MID technology is employed to integrate a smaller pressure sensor onto the blood pump, addressing packaging and connection challenges.
• This advancement aims to facilitate transfemoral placement of the intracardiac pump system.

Impact:

• Enables the development of smaller, transfemoral-compatible intracardiac pumps for enhanced patient support during coronary surgery.
• Paves the way for novel packaging and connection solutions for miniaturized sensors in medical devices.
• Advances the application of MID technology in the medical field for next-generation cardiovascular support.
