Intracardiac suture device
First Claim
1. An intracardiac suture device, comprising:
- a first shaft assembly comprising a first shaft having a lumen passing therethrough from a proximal end to a distal end thereof, a first suture needle-holding means coaxially provided at and spaced from the distal end of the first shaft, and a connector with a hemostatic valve provided on the proximal end of the first shaft;
a second shaft assembly comprising a second shaft having a lumen passing therethrough from a proximal end to a distal end thereof and being slidably arranged in the first shaft assembly, and a connector with a hemostatic valve provided on the proximal end of the second shaft;
a third shaft assembly comprising a hollow third shaft slidably arranged in the second shaft assembly, and handling portion provided at a proximal end of the third shaft; and
a puncture assembly (5) comprising a hollow operating rod provided at a proximal end thereof, and a second suture needle-holding means provided at a distal end thereof and removably arranged in the distal end of the third shaft, said hollow operating rod being connected to the proximal end of the second suture needle-holding means and movably arranged in the third shaft assembly;
wherein said second shaft is protrusible by sliding-movement from the distal end of the first shaft toward the first suture needle-holding means, and wherein a suture needle is transferable between the first suture needle-holding means and the second suture needle-holding means when the third shaft is slid to the distal end of the second shaft after sliding the second shaft to a position where a suture site is held between the second shaft and the first suture needle-holding means.

Abstract
An intracardiac suture device comprises: a first shaft assembly 1 including a first shaft 11 and a first suture needle-holding means 4 provided at a distal end of the first shaft 11; a second shaft assembly 2 comprising a second shaft 21; a third shaft assembly 3 comprising a third shaft 31 and a handling portion 33; and a puncture assembly 5 provided at a proximal end thereof with a second suture needle-holding means 51. The second shaft 21 is protrusible by sliding-movement from the distal end of the first shaft 11 toward the first suture needle-holding means 4, and a suture needle 6 is transferable between the first suture needle-holding means 4 and the second suture needle-holding means 51 when the third shaft 31 is slid to the distal end of the second shaft 21 after sliding the second shaft 21 to a position where a suture site is held between the second shaft 21 and the first suture needle-holding means 4.
