PROBLEM TO BE SOLVED: To provide a catheter deformation device that can readily and reliably deform a tip shape of a catheter into a desired shape, and to provide a catheter deformation device kit including the same.SOLUTION: A catheter deformation device includes a device body 10 having a deformation guide part for fitting a tip part 31a of a catheter 30 thereto. The deformation guide part has a bending part 21b for bending the fitted tip part 31a of the catheter 30. The bending part 21b has a shape for shaping the tip part 31a of the catheter 30 into a desired bending shape when the catheter 30 is removed from the deformation guide part.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2018,JPO&INPIT【課題】カテーテルの先端形状を簡単かつ確実に所望の形状に変形できるカテーテル変形デバイス及びそれを含むカテーテル変形デバイスキットを提供する【解決手段】カテーテル30の先端部31aを嵌合させる変形案内部を有したデバイス本体10を有し、変形案内部は、嵌合したカテーテル30の先端部31aを屈曲させる屈曲部21bを有し、屈曲部21bは、カテーテル30を変形案内部から取り外した際に、カテーテル30の先端部31aが所望の屈曲形状となる形状を有する。【選択図】図4
