Apparatus and methods for endoscopic colectomy are described herein. A colectomy device having a first and a second tissue approximation device is mounted on a colonoscope separated from one another. During deployment of the colectomy device, a diseased portion of the colon is positioned inbetween the tissue approximation devices. The tissue approximation devices are radially expanded such that they contact and grasp the colon wall at two sites adjacent to the diseased portion of the colon. The diseased portion is separated from the omentum and is transected using a laparoscope or is drawn into the colonoscope for later removal. The tissue approximation devices are then urged towards one another over the colonoscope to approximate the two free edges of the colon into contact together where they are fastened to one another using the tissue approximation device as a surgical stapler to create an end-to-end anastomosis.

Apparatus and methods are described allow the techniques of endoscopic and laparoscopic surgery to be combined into a minimally invasive hybrid surgical technique called NOTES-assisted laparoscopic surgery. Manual and robotic-controlled versions of a modular laparoscopic tool are described having a small diameter shaft that is delivered laparoscopically to a surgical site. Larger diameter working tips are delivered through a NOTES delivery tube inserted to the surgical site through a natural orifice and joined to the shaft of the modular laparoscopic tool. Larger diameter working tips improve the effectiveness of the modular laparoscopic tools and the number and size of laparoscopic ports used can also be reduced.

The present invention provides a method and apparatus for controlling a patient's body temperature and in particular for inducing therapeutic hypothermia. Various embodiments of the system are described. The system includes: a source of breathing gas, which may be in the form of a compressed breathing gas mixture; a heat exchanger or other heating and/or cooling device; and a breathing interface, such as a breathing mask or tracheal tube. Optionally, the system may include additional features, such as a mechanical respirator, a nebulizer for introducing medication into the breathing gas, a body temperature probe and a feedback controller. The system can use air or a specialized breathing gas mixture, such as He/Oor SF/Oto increase the heat transfer rate. In addition, the system may include an ice particle generator for introducing fine ice particles into the flow of breathing gas to further increase the heat transfer rate.

An endoscope with guiding apparatus is provided. The endoscope has an elongate body with a steerable distal portion, an automatically controlled portion, a flexible and passively manipulated proximal portion, and an externally controlled and manipulatable guiding apparatus. The guiding apparatus may be positioned within the endoscope or may be positioned adjacent to the endoscope. An interlocking device is provided to slidably interlock the guiding apparatus and the endoscope. When the guide is in a flexible state, it can conform to a curve or path defined by the steerable distal portion and the automatically controlled portion. The guide can then be selectively rigidized to assume that curve or path. Once rigidized, the endoscope can be advanced along the guide in a monorail or “piggy-back” fashion so that the flexible proximal portion follows the curve held by the guide until the endoscope reaches a next point of curvature within a body lumen.

A tunable ablation delivery device is disclosed. The tunable ablation delivery device includes a housing and a detection element on the housing for detecting a physiological indication. The tunable ablation delivery device further includes an ablation element disposed within the housing. An opening in the housing is positioned relative to the ablation element to facilitate a treatment using the ablation element modality.

A therapeutic treatment system has a delivery device is adapted to deliver a cooled breathing gas mixture to a patient and an injection device positioned near a distal end of the delivery device. The injection device is coupled to a source of liquid. The treatment system also includes a control system coupled to the delivery device and the injection device. Alternatively, the control system is adapted to control the injection device to release a fluid into the cooled breathing gas mixture to form a frozen mist of fine ice particles in the cooled breathing gas mixture.

An embolic protection device for use in a patient's blood vessel, such as the aorta, has an approximately cylindrical outer structure made of a filter mesh material and an approximately conical inner structure also made of a filter mesh material. On the downstream end of the embolic protection device, the wider end of the conical inner structure is joined to the cylindrical outer structure. The upstream end of the embolic protection device is open for blood to flow between the conical inner structure and the cylindrical outer structure. The space between the conical inner structure and the cylindrical outer structure defines a collection chamber for captured emboli. The narrow upstream end of the conical inner structure has a catheter port with a resilient seal that is sized for passage of a catheter shaft. The filter mesh material may be self-supporting or it may be supported on a resilient-framework or an inflatable framework.

A method of increasing renal function in a patient operates by stimulation of perivascular sympathetic nerves found in the vicinity of the hepatic portal vein and the hepatic artery. The method can be used as a treatment for renal failure or chronic kidney disease. Alternatively, the method can be used as a prophylactic treatment for preventing contrast-induced nephropathy or any other toxic nephropathy, which can result in renal failure. The perivascular sympathetic nerves can be stimulated by applying energy, such as electrical energy, light, vibration, and ultrasonic vibration, to the perivascular sympathetic nerves. Various methods are described for stimulating the perivascular sympathetic nerves using electrodes that are placed using minimally-invasive techniques.

Embolic protection elements are integrated with a catheter or access sheath for any catheter. A catheter with an integrated embolic protection element comprises a catheter shaft, an embolic filter slidably mounted on a distal portion of the shaft, a proximal stop for limiting the proximal movement of the embolic filter, and a distal stop for limiting the distal movement of the embolic filter. The filter comprises a porous mesh material defining a collection chamber for captured emboli and has a collapsed and a deployed configuration. The filter may be collapsed by an access sheath used with the catheter. An access sheath may comprise a tubular main body and an embolic filter mounted on the distal portion of the tubular main body. The embolic filter may evert into the central lumen of the sheath or may be constrained on the exterior of the sheath with a larger diameter outer tube.
