Methods and assemblies for reducing the volume of a lung. A plurality of anchors are anchored at different positions in the lung. A cord is attached to each of the anchors. The anchors are drawn towards one another via the cords to cause the lung to collapse, thus compressing the tissue in the lung and establishing a reduction in lung volume.

Method and assembly for lung volume reduction

The invention provides improved methods and devices for heating a thermally conductive fluid within an internal body organ to thermally ablate or necrose the body organ. In an exemplary embodiment, the invention provides a thermal ablation device having an elongate member with a proximal end and a distal end. A heating apparatus is provided near the distal end of the elongate member which is constructed to heat a thermally conductive fluid without substantial direct heating of the heating apparatus. A fluid circulator is provided near the heating apparatus which circulates the thermally conductive fluid past the heating apparatus.

Devices and methods for providing access to a body cavity without substantial loss of inflation gas therein. The device comprises an access assembly 10 that may have a tubular member 12, at least one sleeve 16 coaxially disposed over the tubular member, a pneumostasis valve 13 attached to the tubular member, and an obturator 11 removably received in the tubular member. Sleeve 16 comprises expandable region 19 capable of forming an anchor 30 upon axial compression. A method to provide access using assembly 10 comprises insertion of the assembly 10 into the body cavity, expanding region 19, and insufflating the cavity with gas. Expandable region 19 on assembly 10 is axially compressed to form anchor 30 to seal against an interior wall of the body cavity. The method may further comprise either a second expanded anchor 50 or a non-expanding anchor 40 which clamps against an exterior wall of the body cavity to securely position and seal the access assembly 10.

An access system comprises a radially expandable sleeve, a pneumoperitoneum needle, a cannula assembly, and an obturator. Methods for reconstructing and reusing the access system comprise replacing the radially expandable sleeve and cannula valve cap components of the system, both of which are disposable. All remaining system components may be sterilized and reused one or more times. The pneumoperitoneum needle can be separated into tubular needle body and needle stylet components, which may be separately replaced or sterilized and reused. Similarly the cannula comprises both a cannula hub and a cannula tube, where the hub and tube may be separately replaced or sterilized.

Methods and systems for introducing articles and surgical instruments to target body cavities utilize conformable sleeves which are percutaneously positioned within the cavity. Articles may then be passed directly through the conformable sleeve, without use of a rigid cannula, either by pushing the articles inwardly through the sleeve using an introducer or pulling the articles inwardly through the sleeve using a tapered carrier. Surgical instruments are also passed directly inwardly through the sleeve. Such systems and methods may be used in a variety of minimally invasive surgical procedures.

Percutaneous access devices are provided with cleaning elements for in situ cleaning of viewing scope lenses during surgical procedures. The access devices will comprise a cannula having an access lumen therethrough. The cleaning element will be disposed at or near the distal end of the cannula, preferably over or across a distal port of the cannula. The cleaning element may comprise an elastomeric membrane, an open cell foam pad, one or more articulated plates, or a combination thereof. Cleaning of the lens of the viewing scope is effected by moving the lens between positions proximal of and distal to the cleaning element.
