Abstract

A system for tissue approximation and fixation is described herein. The devices are advanced in a minimally invasive manner within a patient'"'"'s body to create one or several divisions or plications within a hollow body organ. The system comprises a tissue acquisition and folding device and a tissue stapling or fixation device, each of which is used together as a system. The acquisition device is used to approximate tissue regions from within the hollow body organ and the stapling device is advanced through a main lumen defined through the acquisition device and is used to affix the approximated tissue. The stapling device is keyed to maintain its rotational orientation relative to the acquisition device as well as to provide the user positional information of the stapling device. The acquisition device is also configured to provide lateral stability to the stapling device prior to the stapling device being clamped onto tissue.

Claims

1-78. -78. (canceled)

79. A tissue acquisition and fixation system, comprising:

a tissue acquisition device having an elongate main body defining a main lumen therethrough, wherein a distal end of the acquisition device is adapted to acquire tissue from within a hollow body organ and reconfigure the tissue into at least one overlap region; and

a tissue fixation device having an articulatable cartridge assembly adapted to be advanced through the main lumen while maintaining a fixed orientation relative to the main lumen.

80. The system of claim 79, wherein the tissue acquisition device further comprises at least two opposing members longitudinally positioned relative to one another at a distal end of the main lumen such that the cartridge assembly is stabilized from lateral movement between the at least two opposing members.

81. The system of claim 79, wherein the tissue acquisition device further comprises at least a first acquisition member positioned at the distal end of the acquisition device.

82. The system of claim 79, wherein the tissue acquisition device comprises at least a first acquisition member and a second acquisition member each positionable correspondingly in apposition to one another at the distal end.

83. The system of claim 82, wherein the first acquisition member and the second acquisition member are simultaneously articulatable from a first delivery configuration to a second expanded configuration.

84. The system of claim 79, wherein the tissue acquisition device further comprises an atraumatic distal tip.

85. The system of claim 84, wherein the distal tip is tapered.

86. The system of claim 79, wherein the elongate main body of the tissue acquisition device is configured to be curved.

87. The system of claim 79, further comprising a handle connected to a proximal end of the main body.

88. The system of claim 87, wherein the handle further comprises at least one actuation mechanism adapted to articulate the distal end of the acquisition device.
