20080243148 | SUTURE INSTRUMENT - A suture instrument that is inserted into a body and ejects an elongated anchor to be engaged to tissue, consisting of: an elongated member that extends from a proximal end on a hand side to a remote end that is introduced to tissue and has flexibility; a needle that is provided at the remote end of the elongated member, has at the distal end a sharp tip that is capable of puncturing tissue, is capable of housing a plurality of the anchors inside, and is provided with a side hole through which the anchors are capable of passing; a pusher whose remote end abuts the anchor that is housed in the needle and is disposed in a manner to be capable of moving in the axial direction of the elongated member; and a push-out control portion that is provided in the needle or the pusher and changes the movement direction of the anchor that has been moved to a formation position of the side hole by the pusher from the length-wise direction of the needle to a direction heading toward the side hole. | 10-02-2008 |
20090069822 | TISSUE FASTENING TOOL, STENT, APPLICATOR FOR PLACING THE SAME, AND TISSUE FASTENING METHOD THROUGH NATURAL ORIFICE - The tissue fastening apparatus includes: a tissue fastening tool provided with a first tissue fixing section which is hooked onto a first biological tissue and a second tissue fixing section which is hooked onto a second biological tissue adjacent to the first biological tissue; a stent provided with a dilating portion having a diameter which increases from a front end to a rear end of the dilating portion, an indwelled portion which is connected the dilating portion, and a through hole which passes through the dilating portion and the indwelled portion in a longitudinal direction of the stent; and an applicator provided with a tubular puncturing tool in which the tissue fastening tool is inserted, a fastening tool pusher inserted into the puncturing tool to dispenses the tissue fastening tool inserted into the puncturing tool from a distal end of the puncturing tool, and a sheath into which the puncturing tool is inserted to shift the stent which is detachably disposed at the distal end of the sheath relative to the puncturing tool. | 03-12-2009 |
20090088780 | SUTURING DEVICE - A suturing device is disclosed which sutures a tissue using a suture unit having a suture thread with both ends fitted to a first anchor and a second anchor, respectively. The suturing device includes a hollow tip member receiving the first and second anchors; a wire having a front end inserted through the tip member so that the first and second anchors can be released out from the tip member; a flexible tube having a distal end integrally connected at a proximal end of the tip member, through which the wire is inserted so as to freely move forward and backward in the axial direction of the tube; a parallel member inserted through the tube so as to freely move forward and backward in the axial direction of the tube along with the wire; a relative position holding member fitted to the wire so as to hold constant a relative positional relationship between the wire and the parallel member; a forward movement restricting member provided on the tube or the tip member so as to restrict a forward movement of the parallel member; and an operating portion provided at a proximal end side of the wire and the parallel member so as to operate the wire and the parallel member. In a state in which the relative positional relationship between the wire and the parallel member is held constant by the relative position holding member, when the wire is moved in the forward direction until the forward movement of the parallel member is restricted by the forward movement restricting member, only the first anchor is released out from the tip member by the movement of the wire. | 04-02-2009 |
20090125039 | SUTURE INSTRUMENT - A suture instrument that is inserted into a body and ejects an elongated anchor to which a suture thread that sutures a perforation is connected and which is placed on tissue, including a base that extends from a proximal end on a hand side to a remote end that is introduced to tissue and has flexibility; an anchor holding instrument that is disposed at the remote end of the base, is capable of housing a plurality of the anchors inside, and whose distal end that ejects the anchors is approximately pointed in the direction of the proximal end of the base; a tip position changing mechanism that is provided for changing the tip position of the anchor holding instrument and causes the anchor holding instrument to move in a direction that intersects with the axial line of the lengthwise direction of the base; and a position operation device that operates the tip position changing mechanism at the hand side and operates the tip position of the anchor holding instrument. | 05-14-2009 |
20090182192 | TREATING TOOL FOR ENDOSCOPE - An endoscope treatment instrument having a needle for puncturing a biological tissue in a body cavity includes an indicator region provided on the outer surface of the needle including an indicator shape having miniature concave portions, and a plain region without the indicator shape provided in connection with at least one side of the indicator region in the axial line direction of the needle. | 07-16-2009 |
20090259232 | SUTURE DEVICE - A suture device which sutures tissue using a suture unit having a first anchor and a second anchor respectively attached to both ends of a suture thread, wherein a hollow distal member is provided which houses said first anchor and second anchor, the end face of the distal side of said distal member is formed so as to constitute a first sharp angle with the axis of said distal member, the distal side of said second anchor is provided with a sloped face so as to constitute a second sharp angle with the axis of said second anchor which is an angle at or below said first sharp angle, and said first anchor and said second anchor are axially aligned and housed inside said distal member so that said second anchor is positioned on the proximal side. | 10-15-2009 |
20100030236 | SUTURING DEVICE - A suturing device is disclosed which sutures a tissue using a suture unit having a suture thread with both ends fitted to a first anchor and a second anchor, respectively. The suturing device includes: a hollow tip member receiving the first and second anchors; a wire having a front end inserted through the tip member so that the first and second anchors can be released from the tip member; a flexible tube having a distal end integrally connected to a proximal end portion of the tip member, through which the wire is inserted so as to freely move forward and backward in the axial direction of the tube; a main body fixed to a proximal end of a sheath through which the tube is inserted; and a sliding portion fixed to the proximal end of the tube and fitted to the main body so as to freely move with respect to the main body in the axial direction in a sliding manner. The sliding portion includes a slider fixed to the proximal end of the tube, and a slider control portion which controls a sliding movement of the slider with respect to the main body in a normal state, and deactivates the control by a predetermined operation. | 02-04-2010 |
20100030237 | SUTURE INSTRUMENT - A suture instrument includes: a therapeutic insertion section having a suture section formed on the distal end thereof and suturing a tissue endoscopically; a cylindrical main operation unit connected to a proximal end of the therapeutic insertion section; a rod section inserted into the main operation unit along an axial line of the main operation unit from a proximal end of the main operation unit, the rod section conducting operations for discharging a suture thread and a plurality of end section members connected to at least an end of the suture thread from a distal end of the suture section; a pusher's distal end section for pressing the end section member to move corresponding to the operations conducted by the rod section; and a guide mechanism for rotating the rod section by a predetermined degree in the circumferential direction after conducting a linear movement of the pusher's distal end section at a position where one of the end section member is fed from a distal end of the suture section, and guiding so that the rod section is rotated in the circumferential direction by the predetermined degree repeatedly after conducting a linear movement of the pusher's distal end section to a position where the other one of the end section members is fed from the distal end of the suture section, so that each one of the end section members is discharged one after another and so that the end section members can be separated finally. | 02-04-2010 |
