Flexible endoscope capsule
First Claim
1. An endoscopic device including a tube member having a distal end adapted for insertion into a patient and an imaging apparatus for providing an image of an area proximate to said distal end of said tube member, said endoscopic device further comprising:
- a housing for selective attachment to a distal end of an endoscopic device, said housing having an internal chamber;
a first aperture extending through said housing to said internal chamber, said first aperture being adapted to engage said distal end of said tube member;
a second aperture extending through said housing to said internal chamber for providing access to patient tissue disposed adjacent to said housing during an endoscopic procedure; and
a needle selectively moveable from a first position within said internal chamber through said second aperture to a second position outside of said internal chamber, wherein in said second position said needle projects from said housing and is engageable with patient tissue, and wherein said needle is moveable from said second position to said first position to dispose engaged tissue through said second aperture into said internal chamber.

Abstract
An endoscopic capsule adapted for selective attachment to the distal end portion of an endoscopic device. The capsule is designed for insertion with an interconnected endoscopic device into a patient body to provide an open space in front of the distal end of the endoscopic device. The capsule facilitates the performance of endoscopic procedures providing a space in which to manipulate medical instruments within the patient body as well as improving a surgeon'"'"'s field of vision within the patient body. In one embodiment, the capsule includes a housing having an internal chamber and two apertures. A first aperture is interconnectable to the end of an endoscopic device and provides operative access to endoscopic instruments contained therein. One or more of these endoscopic devices are advanceable into the internal cavity for selectively engaging patient tissue disposed relative to the second aperture.

18. An endoscopic device, comprising:
-
a tube member having a distal end adapted for insertion into a patient body;
a housing having an internal chamber, said housing being interconnected to said distal end of said tube member wherein said tube member extends through a first aperture in said housing and a second aperture extends through a sidewall of said housing;
an imaging apparatus positionable relative to said distal end, said imaging apparatus being operative to provide a field of view of said internal chamber; and
a needle having an arcuate distal end, said needle being positionable through said distal end of said tube member, wherein said needle is advanceable through said second aperture to engage patient tissue and retractable through said second aperture to dispose engaged tissue into said internal chamber and into said field of view. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27)

28. A method for performing an endoscopic procedure, said method comprising:
-
first positioning an endoscopic capsule disposed on the end of a tube member adapted for insertion into a patient body relative to a target area of patient tissue within a patient lumen, said capsule having an internal chamber;
second positioning an aperture extending through said capsule to said internal chamber adjacent to said target area of patient tissue;
first advancing a suture device associated with an endoscopic device from a first position within said tube member into said internal chamber;
disposing at least a portion of said target area of patient tissue through said aperture into said internal chamber;
suturing said target area of patient tissue, wherein said suturing is performed within said internal chamber. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40)

41. A method for performing an endoscopic procedure, said method comprising:
-
positioning an endoscopic capsule disposed on the end of a tube member adapted for insertion into a patient body relative to a target area of patient tissue within a patient body, said capsule having an internal chamber;
applying suction through said tube member and said capsule to dispose said target area of tissue through an aperture extending through said capsule to said internal chamber;
restricting movement of at least a portion of said target area of tissue relative to said aperture; and
advancing a needle through at least a portion of said target area of tissue disposed within said internal chamber, wherein said needle advances form a first position within said internal chamber to a second position within said internal chamber in conjunction with said advancing. - View Dependent Claims (42, 43, 44, 45, 46, 47)
