Abstract
Endoscopic devices and methods used for fastening multiple tissue layers, such as, for example, an endoscopic fundoplication procedure, are disclosed. The endoluminal device includes a tissue fastener, a flexible needle having means for grasping and releasing a portion of the tissue fastener, and a deflector for deflecting and guiding the needle toward the multiple tissue layers.
Claims30
An endoluminal surgical device for fastening multiple tissue layers, comprising:
- a tissue fastener;
- a flexible needle having means for grasping and releasing a portion of the tissue fastener;
- a deflector for deflecting and guiding the needle toward the multiple tissue layers;
- and
- a flexible tube having at least one lumen and configured to extend from outside of a body to inside the body, wherein the tube is configured to accommodate the tissue fastener, the flexible needle, and the deflector inside the lumen during delivery.
An endoluminal surgical device for fastening multiple tissue layers, comprising:
- a tissue fastener;
- a flexible needle having a grasper for grasping a portion of the tissue fastener;
- and
- a deflector for deflecting and guiding the needle toward the multiple tissue layers,
- wherein the grasper comprises:
- a suction hole proximate a distal end of the flexible needle;
- and
- a suction conduit formed inside the flexible needle,
- wherein the suction hole is configured to receive the portion of the tissue fastener into and out of the suction hole during operation.
An endoluminal surgical device for fastening multiple tissue layers, comprising:
- a tissue fastener;
- a flexible needle having means for grasping and releasing a portion of the tissue fastener;
- a deflector for deflecting and guiding the needle toward the multiple tissue layers;
- and
- an A-frame head configured to receive the deflector and move axially relative to the deflector.
An endoluminal surgical device for fastening multiple tissue layers, comprising:
- a tissue fastener;
- a flexible needle having means for grasping and releasing a portion of the tissue fastener;
- and
- a deflector for deflecting and guiding the needle toward the multiple tissue layers;
- wherein the deflector defines a conduit therein for guiding the needle, the conduit is curved to deflect and guide the needle toward the multiple tissue layers, and the conduit includes a proximal portion and a distal portion, the proximal portion extending substantially axially within the deflector and the distal portion angled relative to the proximal portion, and
- wherein the distal portion communicates with an opening defined by a side surface of the deflector.
An endoluminal surgical device for fastening multiple tissue layers, comprising:
- a tissue fastener;
- a flexible needle having means for grasping and releasing a portion of the tissue fastener;
- and
- a deflector for deflecting and guiding the needle toward the multiple tissue layers;
- wherein the deflector defines a conduit therein for guiding the needle, the conduit is curved to deflect and guide the needle toward the multiple tissue layers, and the conduit includes a proximal portion and a distal portion, the proximal portion extending substantially axially within the deflector and the distal portion angled relative to the proximal portion, and
- wherein the deflector includes a main body and a distal body releaseably connected to the main body, wherein the main body contains the proximal portion of the conduit and the distal body contains the distal portion of the conduit.
An endoluminal surgical device for fastening multiple tissue layers, comprising:
- a tissue fastener;
- a flexible needle having means for grasping and releasing a portion of the tissue fastener;
- and
- a deflector for deflecting and guiding the needle toward the multiple tissue layers,
- wherein the deflector defines an opening in a side of the deflector configured to receive the tissue fastener and the needle.
