Publication number: 20250152184Abstract: Tools, devices and systems that include a generally cylindrical, hollow shaft, and a suction canister are provided with advantageous interconnectivity features and functions that enable ease of manufacturing, lowered manufacturing costs, and allow for a platform of different shaft embodiments and canister embodiments that may be manufactured in different combinations to form an array of unique instruments. The interconnectivity may be irreversible or reversible, and the connection features maintain an air tight seal between the components. Tools, devices and systems are also provided that include collection functionality that can be employed to manipulate the volume of tissue collected while using a tissue collection feature/function. This may be undertaken to restrict total volume of the collection chamber in a way that allows for continuous suction flow rate to take place while collecting the desired amount of tissue.Type: ApplicationFiled: January 15, 2025Publication date: May 15, 2025Inventors: Maxim Budyansky, Neil Shah, Christopher Chiang, Brandon Craft, Paul Fearis, Edward Land, Douglas Pattison, Marton Varady, Charles R.

Publication number: 20200261662Abstract: An embodiment in accordance with the present invention is directed to a device for fixation, stabilization, and securement of an intravascular cannula to tissue. The fixation device affixes relative to the cannula and cannulated tissue, allowing the needle to be inserted to a shallow depth and then rapidly secured with one motion, using just one hand. The device works to secure cannulae not only in small vessels but also in situations non-permissive to current state-of-the-art cannulas—such as on wet, adhesive-incompatible surfaces, in intra-operative applications, or when hands-free securement is required. The device can also be utilized to access the umbilical arteries and vein for purposes of placental perfusion for cord blood collection or to facilitate and extend the duration of conventional cord blood collection.Type: ApplicationFiled: January 21, 2020Publication date: August 20, 2020Inventor: Christopher CHIANG
