Abstract

An endoscopic instrument used to form an artificial valve for treating gastroesophageal reflux disease (GERD).

Claims

1. A tissue piercing device, to be used with an endoscope for suturing or ligating tissues in body cavities, said tissue-piercing device comprising:

two piercing members each comprising a needle, said two needles being parallel and spaced apart at a constant interval;

two slidable suture holding means for holding a suture, said suture holding means being respectively slidably inserted through the two needles to be extendable and retractable with respect to distal ends of the needles; and

holding operation means for operating both said suture holding means.

2. A tissue piercing device according to claim 1, wherein each of the suture holding means comprises a loop;

wherein a respective driving member is connected to a proximal end of each said suture holding means, the driving member being operable for rotating, advancing, and retracting the corresponding suture holding means; and

wherein a center axis of each of the suture holding means is inclined with respect to a longitudinal axis of the corresponding driving member.

3. A treatment system comprising:

a first endoscope;

the tissue piercing device according to claim 1 mounted on a distal end of the first endoscope;

a second endoscope that is different from the first endoscope;

a tissue fixing device provided at least at a distal end of the second endoscope for fixing a site to be sutured; and

a suture slidably inserted through the second endoscope.

4. The treatment system according to claim 3, wherein the tissue fixing device comprises an engaging portion that engages the suture, and wherein a knot formed in the suture is delivered to a sutured site by advancing the second endoscope toward the sutured site while the suture is engaged with the engaging portion.

5. The tissue piercing device according to claim 1, further comprising an engaging portion that engages the suture, wherein a knot formed in the suture is delivered to a sutured site by advancing the tissue piercing device toward the sutured site while the suture is engaged with the engaging portion.

6. A tissue piercing device to be used with an endoscope for suturing or ligating tissues in body cavities, said tissue piercing device comprising:

two piercing members each comprising a needle, said two needles being parallel and spaced apart at a constant interval;

two slidable suture holding portions respectively slidably inserted through the two needles to be extendable and retractable with respect to distal ends of the needles; and

a holding operation portion for operating the suture holding portions;

wherein each of the suture holding portions comprises a suture holding section adapted to extend from the distal end of the respective needle to capture a suture and to retract into the distal end of the needle to pull the suture into the needle.

7. A tissue piercing device according to claim 6, wherein each of the suture holding portions comprises a loop;

wherein a respective driving member is connected to a proximal end of each of the suture holding portions, the driving member being operable for rotating, advancing, and retracting the suture holding portion; and

wherein a center axis of each of the suture holding portions is inclined with respect to a longitudinal axis of the respective driving member.

8. A treatment system, to be used with an endoscope for suturing or ligating tissues in body cavities, said treatment system comprising:

first and second endoscopes for peroral insertion through body cavities;

a tissue piercing device mountable to the first endoscope, said tissue piercing device having two piercing members each comprising a needle, and said two needles being parallel and spaced apart at a constant interval;

a tissue fixing device projecting from a distal end of the second endoscope for fixing a site to be pierced;

a suture holding portion slidably inserted through at least one of the needles of the tissue piercing device; and

a suture being slidably inserted through one of;

one of the needles of the tissue piercing device, and the second endoscope.

9. A treatment system according to claim 8, wherein each said suture holding portion comprises a loop;

wherein a respective driving member is connected to a proximal end of each said suture holding portion, the driving member being operable for rotating, advancing, and retracting the suture holding portion; and

wherein a center axis of each said suture holding portion is inclined with respect to a longitudinal axis of the respective driving member.
