MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202611106633 A) filed by Tanmoy Ghatak; and Neelima Kulshrestha on September 04, 2026, for A Hollow Guidewire And Guidewire Retaining Syringe Attachment Device For Vascular Cannulation.
Inventors include Tanmoy Ghatak; and Neelima Kulshrestha.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: The present invention relates to a hollow guidewire and guidewire retaining syringe attachment device assembly for vascular cannulation, particularly for facilitating confirmation of intravascular 5 placement of a guidewire. The assembly comprises a hollow guidewire having an elongated guidewire body defining an internal lumen extending between a distal end and a proximal end, the distal end being provided with a flexible atraumatic J-shaped tip. The hollow guidewire has an outer diameter of 0.7-1 mm and an internal lumen having an internal diameter of 0.4 0.6 mm, while the J-shaped tip has a loop circle diameter of 3-6 10 mm. The assembly further comprises a guidewire retaining syringe attachment device having guidewire receiving passages including sequentially arranged funnel-shaped openings for guiding the proximal end of the hollow guidewire towards one or more retaining notches. A movable flap having a channel is coupled to the attachment device through a hinge and is configured to retain the hollow guidewire against the retaining notch when moved to a closed position and secured by a snap-lock arrangement. The attachment 15 device further facilitates connection of a syringe with the internal lumen of the hollow guidewire. Upon operation of the syringe, negative pressure is generated within the internal lumen to aspirate blood through the distal end of the hollow guidewire while the guidewire is retained by the attachment device, thereby facilitating confirmation of intravascular placement during vascular cannulation.
