## Abstract

A medical apparatus including: a projecting member; an introducing sheath; an extrusion member inside the introducing sheath, at a proximal side of the projecting member and movable in an axial direction with respect to the introducing sheath; a cover sheath outside the introducing sheath, the introducing sheath being movable between a first and second position with respect to the cover sheath; an introducing sheath manipulating section at a proximal side of the introducing sheath; an extrusion member manipulating section at a proximal side of the extrusion member; a cover sheath manipulating section at a proximal side of the cover sheath; and a release member on the cover sheath manipulating section and/or the introducing sheath manipulating section to release a fixation between the extrusion member manipulating section and the introducing sheath manipulating section when the introducing sheath is disposed on the first or second position.

## Claims

### Claim 1

A medical apparatus comprising:
at least one projecting member;
an introducing sheath configured to be introduced to a target portion in a state in which the projecting member is suspended, wherein the introducing sheath has a sharp distal end which is configured to pierce a living tissue;
an extrusion member disposed inside the introducing sheath and at a proximal side of the at least one projecting member movable in an axial direction with respect to the introducing sheath;
a cover sheath configured to be disposed outside the introducing sheath, the introducing sheath being movable between a first position and a second position with respect to the cover sheath;
an introducing sheath manipulating section provided at a proximal side of the introducing sheath;
an extrusion member manipulating section provided at a proximal side of the extrusion member, wherein the extrusion member manipulating section and the introducing sheath manipulating section are slidably and integrally provided with each other;
a housing having a distal end and a proximal end configured for housing the introducing sheath manipulating section and the extrusion member manipulating section; and
a release member slidably engaged with the cover sheath manipulating section and the introducing sheath manipulating section, wherein movement of the introducing sheath manipulating section toward the distal end of the housing will actuate the sharp distal tip of the introducing member for piercing the living tissue and release an integration between the extrusion member manipulating section and the introducing sheath manipulating section.

### Claim 2 (depends on 1)

The apparatus according to claim 1, wherein the projecting member extends in a major axial direction and has an engaging surface which is configured to engage with a living tissue and a connecting portion connected to a suture, and the introducing sheath is suspended detachably.

### Claim 3 (depends on 1)

The apparatus according to claim 1, further comprising a sheath section configured to be disposed outside the cover sheath, the cover sheath configured to be arranged on an inner wall of the sheath section, wherein a distal end of the cover sheath is configured to be disposed at a position retracted more proximally than a distal end position of the sheath section.

### Claim 4 (depends on 1)

The apparatus according to claim 1, further comprising a sheath section configured to be disposed outside the cover sheath, the cover sheath configured to be arranged on an inner wall of the sheath section, wherein the cover sheath includes a partition wall configured to be disposed on the inner wall of the sheath section.

### Claim 5 (depends on 4)

The apparatus according to claim 4, wherein the partition wall is formed integrally with the sheath section.

### Claim 6 (depends on 4)

The apparatus according to claim 4, wherein the partition wall is fixed to the sheath section.
