The Crawling Heart Robot


Robotics is an ever-advancing and emerging filed of the new era. With robots in the health sector, healthcare professionals have been able to achieve otherwise unattainable targets or goals that were once too difficult to meet. One such breakthrough is the HeartLander, a mini crawling robot designed to access the regions of the heart that are either inaccessible or require extensive surgery with high morbidity and mortality rates.

HeartLander is a mini mobile heart bug that delivers therapies to the beating heart with minimum invasion.

The operating surgeon/physician has to make a small percutaneous incision below the xiphoid process of the sternum from where the HeartLander is inserted. Using vacuum pressure, it adheres to the beating heart’s epicardium, then semi-autonomously navigates to the desired region of the heart and administers the specific therapy. In other words, it provides precise and stable access to the beating heart.

How does the HeartLander reach a specific location?

HeartLander has wire-drive actuators and a tracking sensor that navigates it semi-autonomously to the specific locations at a speed of 4mm per second. The operator has a joystick to control the robot according to the graphical representation of the robot on the epicardial surface. The locomotion enables HeartLander to access the otherwise inaccessible or hardly accessible areas of the epicardium

HeartLander can be inserted on an outpatient basis! This procedure doesn’t require general anesthesia.

HeartLander has a working channel. Upon reaching the desired & targeted location, therapies can be administered and therapeutic devices can be applied to the heart, including ablation catheters for atrial fibrillation, injections, and pacing leads. When compared with the existing robotics in cardiac surgery, HeartLander improves accessibility, cardiac stabilization, and precision. It decreases the morbidity associated with access. Above all, it’s comparatively inexpensive, and it is disposable.

HeartLander was able to traverse the heart and reach the targeted locations autonomously when studied on beating porcine (pig) heart. Moreover, preclinical feasibility studies have demonstrated myocardial injection of dye, epicardial lead placement, and epicardial ventricular ablation from HeartLander.

Dr. Arsia Hanif has been a meritorious Healthcare professional with a proven track record throughout her academic life securing first position in her MCAT examination and then, in 2017, she successfully completed her Bachelors of Medicine and Surgery from Dow University of Health Sciences. She has had the opportunity to apply her theoretical knowledge to the real-life scenarios, as a House Officer (HO) serving at Civil Hospital. Whilst working at the Civil Hospital, she discovered that nothing satisfies her more than helping other humans in need and since then has made a commitment to implement her expertise in the field of medicine to cure the sick and regain the state of health and well-being. Being a Doctor is exactly what you’d think it’s like. She is the colleague at work that everyone wants to know but nobody wants to be. If you want to get something done, you approach her – everyone knows that! She is currently studying with Medical Council of Canada and aspires to be a leading Neurologist someday. Alongside, she has taken up medical writing to exercise her skills of delivering comprehensible version of the otherwise difficult medical literature. Her breaks comprise either of swimming, volunteering services at a Medical Camp or spending time with family.
