Abstract
Devices and methods useful for transluminally accessing a body cavity are disclosed. In one embodiment, a transluminal access device adapted to be inserted through a body lumen is provided and can include an inner shaft having an opening at its distal end and adapted to be positioned adjacent to an inner wall of a body lumen. The inner shaft can include one or more sealing mechanisms, such as one or more seals with suction ports formed thereon for isolating a portion of a body lumen. The isolated portion may be sterilized and serve as an access point or otomy site for penetrating the wall of the body lumen to access a body cavity.
Claims21
A translumenal access device, comprising:
- an inner shaft adapted to be inserted through a body lumen and having proximal and distal ends with an inner lumen extending therethrough, the distal end including an opening adapted to be positioned adjacent to an inner wall of a body lumen containing the inner shaft;
- and
- an outer shaft disposed around at least a portion of the inner shaft;
- a sealing mechanism coupled to a distal portion of the outer shaft and at least partially disposed around and movable relative to the inner shaft, the sealing mechanism having a first seal positioned distal of the opening and a second seal positioned proximal of the opening, the first seal being formed on a distal tip coupled to the distal end of the outer shaft by one or more struts extending therebetween such that the first seal is spaced apart from a distal-most end of the outer shaft, and the second seal being disposed around the distal-most end of the outer shaft, the first and second seals each having a plurality of suction ports formed around an outer perimeter thereof and adapted to suction tissue thereon so as to form a seal around an inner wall of a body lumen and to isolate the opening in the inner shaft within a portion of a body lumen.
A translumenal access system, comprising:
- an outer shaft having proximal and distal ends with an inner lumen extending therethrough, the outer shaft being adapted to be inserted through a body lumen;
- an access element extending from the distal end of the outer shaft and having at least one opening formed therein and configured to be positioned adjacent to an inner wall of a body lumen;
- a first annular seal coupled to the outer shaft and positioned distal of the opening, the first annular seal being configured to engage and to form a seal with an inner wall of a body lumen;
- and
- a second annular seal coupled to the outer shaft and positioned proximal of the opening, the second annular seal being configured to engage and to form a seal with an inner wall of a body lumen, wherein the first and second annular seals each include a plurality of suctions ports formed around an outer perimeter thereof and adapted to suction tissue thereon, and wherein the first annular seal is formed on a distal tip coupled to the distal end of the outer shaft by one or more struts extending therebetween such that the first seal is spaced apart from a distal-most end of the outer shaft, and the second annular seal is disposed around the distal-most end of the outer shaft.
A translumenal access system, comprising:
- an outer shaft having proximal and distal ends with an inner lumen extending therethrough, the outer shaft being adapted to be inserted through a body lumen;
- an access element extending from the distal end of the outer shaft and having at least one opening formed therein and configured to be positioned adjacent to an inner wall of a body lumen;
- an expandable member disposed around the perimeter of the opening to stabilize the opening relative to a tissue surface;
- a first annular seal formed on a distal tip coupled to the distal end of the outer shaft by one or more struts extending therebetween such that the first seal is spaced apart from the distal-most end of the outer shaft and positioned distal of the opening, the first annular seal being configured to engage and to form a seal with an inner wall of a body lumen;
- and
- a second annular seal coupled to the outer shaft and positioned proximal of the opening, the second annular seal being configured to engage and to form a seal with an inner wall of a body lumen.
