Blood vessel holding device

A balloon catheter for interatrial septum dehiscence including an expandable and contractible balloon, and a shaft to which the balloon can be attached at the distal end thereof, wherein fixing members are provided at balloon mounting portions to be attached to the shaft. The fixing members are a pair of members in opposed relationship to each other at the ends of the balloon. The pair of members generally has an identical shape.

Balloon catheter

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.

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
