Blood vessel holding device

A graft grasping device includes a graft grasping member including a soft tubular grasping portion having a substantially C-shaped cross section and a suction tube which communicates with a lumen of the grasping portion and is connected to a side wall of the grasping portion. A recessed portion including at least a communication port which communicates with a lumen of the suction tube and the lumen of the grasping portion is formed on an inner wall of the grasping portion. The recessed portion is covered with a porous sheet and a mesh sheet is interposed between the recessed portion and the porous sheet.

Graft grasping device

An intracardiac suture device comprises a first shaft assemblyincluding a first shaftand a first suture needle-holding deviceprovided at a distal end of the first shaft; a second shaft assemblycomprising a second shaft; a third shaft assemblycomprising a third shaftand a handling portion; and a puncture assemblyprovided at a proximal end thereof with a second suture needle-holding device. The second shaftis protrusible by sliding-movement from the distal end of the first shafttoward the first suture needle-holding device, and a suture needleis transferable between the first suture needle-holding deviceand the second suture needle-holding devicewhen the third shaftis slid to the distal end of the second shaftafter sliding the second shaftto a position where a suture site is held between the second shaftand the first suture needle-holding device
