MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641051440 A) filed by Sree Balaji Medical College And Hospital, Chennai, Tamil Nadu, on April 22, for 'shunt deployment device for open heart bypass surgery.'
Inventor(s) include Dr. Meenakshi Sundaram; Dr. Sasikumar P; Dr. Kannan; A. Nagoor Kani; Gowtham. P; and Dr. Prabhu K.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a shunt deployment device for use in coronary artery bypass grafting (CABG) surgery on a beating heart. The device comprises a guiding cannula with a tapered distal end for atraumatic alignment with the coronary opening, an insertion mechanism operatively coupled to the cannula for advancing an intracoronary shunt, a stabilizing assembly mechanically linked to the cannula for anchoring the shunt using expandable wings or projections, and a control interface connected to both the insertion mechanism and stabilizing assembly for regulating advancement and secure positioning. The guiding cannula directs the insertion mechanism, the insertion mechanism introduces the shunt, the stabilizing assembly holds the shunt in place, and the control interface coordinates their operation. The device enables continuous coronary perfusion during anastomosis, reduces technical difficulties in shunt placement, and facilitates efficient bypass graft fixation, thereby improving surgical safety and reproducibility."
