Abstract

A device is disclosed for introducing a flexible elongated element through at least two portions of a subject. In an embodiment, the device includes a proximal end and a distal end, as well as an advancement unit for longitudinally advancing the flexible elongated element toward the distal end such that a distal end of the elongated element may pass from the distal end of said device with sufficient force to pass through the portions of the subject. The device also includes a securing unit for variably adjusting a securing force applied by the flexible elongated element to secure together the portions of the subject.

Independent Claims | See all claims (26)

  1. 1. A suturing device comprising: a housing; a shaft extending distally from said housing, at least a portion of said shaft being flexible; a pair of opposing jaws located at a distal end of said shaft; a suture drive mechanism adapted to advance suture material through said shaft, through one of said jaws, through a subject to be sutured, and into the other jaw; and a jaw rotation mechanism adapted to rotate said jaws about an axis oriented along at least a portion of said shaft so as to secure the suture material to the subject.
  2. 9. A suturing device comprising: a housing; a shalt extending distally from said housing; a pair of opposing jaws located at a distal end of said shaft, each of said opposing jaws being (i) pivotally connected to the distal end of said shaft, and (ii) pivotally connected to a yoke movable relative to the distal end of said shaft, whereby movement of the yoke in a distal direction causes each of said opposing jaws to open relative to one another, and movement of the yoke in a proximal direction causes each of said opposing jaws to close relative to one another; a suture drive mechanism adapted to advance suture material through said shaft, through one of said jaws, through a subject to be sutured, and into the other jaw; and a jaw rotation mechanism adapted to rotate said jaws about an axis oriented along at least a portion of said shaft so as to secure the suture material to the subject.
  3. 10. A suture device comprising: a housing; a shaft extending distally from said housing, at least a portion of said shaft being flexible; a pair of movable jaws pivotally connected to a distal end of said shaft in opposing relation such that said jaws can open and close relative to one another; a suture drive mechanism adapted to advance suture material through said shaft, through one of said jaws, through a subject to be sutured, and into the other jaw; and a jaw rotation mechanism adapted to rotate said jaw about an axis oriented along at least a portion of said shaft so as to secure the suture material to the subject.
  4. 16. A suturing device comprising: a housing; a shaft extending distally from said housing; a pair of opposing jaws located at a distal end of said shaft; a suture drive mechanism adapted to advance suture material through said shaft, through one of said jaws, through a subject to be sutured, and into the other jaw; a jaw rotation mechanism adapted to rotate said jaws to secure the suture material to the subject; and a source of the suture material comprising (i) a distal portion having properties favorable for penetrating, twisting and cutting operations, and (ii) a proximal portion having properties favorable for driving operations, said source of suture material being located in the device so that said proximal portion of the suture material is engaged by said suture drive mechanism.
  5. 21. A method for treating gastroesophogeal reflux disease (GERD), comprising: providing a suturing device comprising: a housing; a shaft extending distally from said housing; a pair of opposing jaws located at a distal end of said shaft; a suture drive mechanism adapted to advance suture material through said shaft, through one of said jaws, through a subject to be sutured, and into the other jaw; and a jaw rotation mechanism adapted to rotate said jaws so as to secure the suture material to the subject; advancing a distal end of the suturing device into a patient's stomach so that the distal end of the suturing device is adjacent to a wall of the stomach below the lower esophageal sphincter (LES); gathering together portions of the stomach wall below the LES with said pair of opposing jaws; operating said suture drive mechanism so as to advance the suture material through the gathered-together portions of the stomach wall; and operating said jaw rotation mechanism to secure the suture material to the subject and thereby secure together the gathered-together portions of the stomach wall.
  6. 24. A method for effecting hemostasis, comprising: providing a suturing device comprising: a housing; a shaft extending distally from said housing; a pair of opposing jaws located at a distal end of said shaft; a suture drive mechanism 4 adapted to advance suture material through said shaft, through one of said jaws, through a subject to be sutured, and into the other jaw and a jaw rotation mechanism adapted to rotate said jaws so as to secure the suture material to the subject; advancing the distal end of a suturing device into a patient adjacent to tissue which would benefit by effecting hemostasis; gathering together portions of the tissue which would benefit by effecting hemostasis with the pair of opposing jaws; operating said suture drive mechanism so as to advance the suture material through the gathered-together portions of the tissue; and operating said jaw rotation mechanism to secure the tissue and thereby effect hemostasis.
