Abstract
A medical tube is disclosed, which is configured to have an elongated implant inserted in the medical tube. The medical tube includes a tube having a proximal end opening where the tube is open at a proximal end of the tube. The tube can include a bent region where an intermediate portion in the longitudinal direction of the tube is bent and where a bent state is maintained, and a connection portion which is provided near the proximal end opening and to which a puncture needle having a sharp needle tip at a distal end of the puncture needle is connected from a needle tip side.
Claims18
A medical tube assembly comprising:
- a puncture needle configured to form an arc-shaped puncture hole in a living body, the arc-shaped puncture hole passing between a urethra and a vagina, the puncture needle having a needle tip at a distal end of the puncture needle, the puncture needle having a tapered portion, wherein an outside diameter of the puncture needle increases along a proximal direction from the needle tip;
- and
- a tube configured to have an elongated implant inserted in the tube and inserted into the arc-shaped puncture hole, the tube comprising:
- a connection portion having a proximal end opening where the tube is open at a proximal end of the tube;
- a bent region distal of the connection portion, the bent region being bent in an arc shape, and wherein the tube is rigid at least in the bent region;
- the connection portion being configured to connect to the puncture needle from a needle tip side;
- the tube having a length longer than a length of the puncture needle;
- and
- wherein the bent region extends from the connection portion to a distal end of the tube.
