Document Type and Number:
WIPO Patent Application WO/2013/081071
Kind Code:
A1
Abstract:
This device (10) for cell transplantation is provided with a catheter (12) and an expanding means (14). An expansion lumen (20), a suction lumen (22), and an injection lumen (24) are formed in parallel in the catheter (12). The expanding means (14) is provided with two circular-arc-shaped expansion bodies (26) that can be expanded by an expansion fluid such as a contrast medium. In a cell-transplantation procedure, with the space between bodily tissues expanded by expansion of the two expansion bodies (26), any liquid (residual liquid) at the target site is suctioned out via the suction lumen (22) and a cell suspension is then injected to the target set via the injection lumen (24).
