Methods and devices are provided for providing surgical access into a body cavity. In one embodiment, a surgical access device is provided that includes a proximal housing and a distal retractor. At least one stability thread can extend around a perimeter of at least a portion of the distal retractor. In some embodiments, the stability thread can be mechanically adjustable to change a diameter of the distal retractor.

An encapsulated medical device includes a radio antenna through which the encapsulated medical device transmits or receives a radio wave to or from an extracorporeal device. The encapsulated medical device is passed through the lumen of a body cavity in order to examine, cure, or treat an internal region of the body cavity under the control of the extracorporeal device. A capsule body included in the encapsulated medical device has an extended portion formed at an upper end of one axis of a cross section of the capsule body cut at right angle to the longitudinal axis thereof. Herein, the cross section of the capsule body is non-circular. However, providing the capsule body does not has the extended portion, the cross section of the capsule body is substantially circular. The capsule body has a linkage hole bored in the extended portion thereof so that when the capsule body comes into close contact with the internal surface of a body cavity to block the lumen thereof, the linkage hole will realize a fluid passage which allows a fluid such as a gas or humor to flow into the forward and backward parts of the lumen.

This application presents methods and devices for continuously cleaning a colon by at least partially filling a segment of the colon with liquid and agitating the fluid to dislodge matter adhering to the colon walls. Methods for automatic maintenance of liquid levels in the colon during continuous cleaning are taught.

Devices and methods are disclosed for accessing a body cavity or other surgical site while providing optimal device length and improved tissue retraction, device retention and stability, and seal integrity. A surgical access device is disclosed that generally comprises an external seal housing having at least one working channel and that is coupled to a flexible and / or resilient retractor. The retractor can include a resilient ring at its distal circumference configured to be deformed to facilitate insertion through an incision and then to return to an undeformed state having a diameter greater than a diameter of the incision once within a body cavity. Various means of coupling the retractor to the housing are disclosed, as are various types of seals that can be included within the housing. “Low-profile”and “peel-away cannula” embodiments of the surgical access device are disclosed, along with methods of accessing a body cavity using such devices.

A contact thermometer for determining-temperature of an inner wall of a cavity, where accuracy and speed response is assured by use of a probe having a variable geometry where the first shape of the probe exists before and during placing the probe into a cavity and the second shape is formed during the measurement process. The temperature measuring tip of the probe makes an intimate thermal contact with an inner wall of a cavity after the second geometrical shape is assumed. The accuracy is assured by use of at least two temperature sensors while the speed response is improved by taking at least two readings, from one temperature sensor.

Two part laparoscopic tools and surgical methods using such tools are presented. The tools and methods enable use of multiple surgical tools each having wide tool heads to be used in a body cavity using a single wide trocar and one or more narrow incisions, thereby reducing surgical risk and enhancing patient comfort and shortening recovery time. Additional instruments for facilitating laparoscopic surgery are also presented.

One aspect of the invention is a method to vent gas from a body cavity during an endoscopic procedure. A body cavity is in fluid communication with an exhaust gas inlet of a vacuum break device. The vacuum break device has a chamber in fluid communication with both the inlet and an outlet. The chamber may comprise one or more openings in fluid communication with the atmosphere. A conduit in fluid communication with the exhaust gas outlet may be connected directly or indirectly to a suction source. The suction source may be activated.

Methods and devices are provided for providing access through tissue to a surgical site. In one embodiment, a surgical access device can include a hollow tubular member and a modular seal member. The modular seal member can be configured to radially span a lumen of the tubular member and can be removably and replaceably matable to a portion of the tubular member. The access device can also include a plurality of access ports, each of which can be configured to mate with the modular seal member at a respective desired location.

The present invention provides an LED lighting apparatus and a method of using the same for illumination of a body cavity. In one aspect, the present invention provides a method of surgery in which one incision is made for hands and surgical instruments, and another incision is made for insertion of an LED lighting device. Both incisions open into the same cavity, and the lighting device provides continuous internal lighting to the body cavity where the operation is occurring. In another aspect, a method and apparatus are described that provide internal chandelier lighting to an internal body cavity using a plurality of switched LED's for surgical without damaging tissue within the body cavity.

An injection needle apparatus in which an operation for relatively moving an outer tube 4 and an inner tube 5 is performed to project and retract a needle body 12 from and into a distal end of the outer tube 4, and to carry out a movement of rotation of the needle body 12 at a predetermined angle by relative forward and backward movements of the outer tube 4 and inner tube 5 in their longitudinal directions every time the forward and backward movement operations is repeated, thereby enabling changing a direction of a needlepoint 14 of the needle body 12 at each angle.

Methods and devices are provided for providing surgical access into a body cavity. In general, the methods and devices allow a surgical access device to be securely positioned within an opening in tissue to provide access to a body cavity underlying the tissue. An actuator can be rotatably disposed on or in a housing of a surgical access device such that rotation of the actuator relative to the housing is effective to move a cannula of the surgical access device between an insertion configuration in which the cannula has a reduced profile enabling it to easily be inserted into a tissue opening, and an expanded profile enabling it to form an anchor against and / or within the tissue opening.
