A surgical instrument including a first portion and a second portion, wherein the second portion can be sterilized separately from the first portion. The first portion can comprise an anvil, a staple cartridge channel and / or staple cartridge, and a movable cutting member. The second portion can comprise electronic components configured to control the surgical instrument and / or record data collected during the use of the surgical instrument. The first portion can be sterilized using a gamma radiation sterilization process while the second portion can be sterilized using a different sterilization process, such as steam, ethylene oxide, ozone, and / or hydrogen peroxide sterilization processes, for example. As a result, the first and second portions can be sterilized separately and delivered in two separate containers. The second portion can be stored within a sealed bag and can include an electrical terminal which can penetrate the bag and communicate with the first portion.

Instrument introducers are disclosed which facilitate the insertion of a surgical instrument into a cavity or a body of a patient. In one embodiment, the instrument introducer includes a hollow elongate cylindrical body including a distal end portion terminating in a distal edge and a proximal end portion, the cylindrical body defining a central longitudinal axis, and an elastomeric cap secured to the distal end portion of the cylindrical body, the cap including a distal end wall having an outer terminal edge and an annular side wall depending from the outer terminal edge thereof. The distal end wall includes an aperture formed therein, wherein a center of the aperture is coaxially aligned with the central longitudinal axis.

An electrosurgical system comprises a radio frequency generator (1), an electrosurgical instrument (E1), and a fluid enclosure (42). The generator (1) has a radio frequency output for delivery of power to the electrosurgical instrument (E1) when immersed in an electrically-conductive fluid. The electrosurgical instrument (E1) has an electrode assembly (32) at the distal end thereof, the electrode assembly comprising a tissue treatment electrode (34), and a return electrode (38) axially spaced therefrom in such a manner as to define, in use, a conductive fluid path that completes an electrical circuit between the tissue treatment electrode and the return electrode. The fluid enclosure (42) is adapted to surround an operation site on the skin of a patient or an incision leading to a cavity surgically created within the patient's body. The fluid enclosure (42) includes sealing means (44) for sealing against the patient's tissue, and the fluid enclosure includes at least one port (50a, 52a) through which the electrosurgical (E1) is insertable, and through which the electrically-conductive fluid can enter and / or leave the enclosure. The fluid enclosure device of the present invention can also be used to treat tumours within the colon. The enclosure, which includes a proximal and a distal bung, is inserted into the colon in a deflated condition and then inflated with a conductive fluid or gas. The colon can be supported against the pressure of the fluid or gas with a pressure sleeve that has been inserted to surround the region of the colon being treated. An electrosurgical instrument is then inserted into the colon and manipulated to vaporize the tumor.

A method is disclosed for treating benign conditions, such as enlarged tonsils and / or adenoids located in a patient's throat or nasopharynx, or soft tissue lesions located in a patient's oropharynx or larynx. According to the method, a space containing the patient's nasopharynx, oropharynx or pharynx and larynx is isolated from the patient's trachea and lungs using an inflatable cuff tracheostomy tube or nasotracheal tube inserted in the patient's trachea. The cuff is inflated to occlude the trachea. The patient is placed in a supine position, whereupon at least a portion of the space containing the nasopharynx and / or oropharynx and larynx is filled with saline. An endoscope is then inserted into the space to view the operative site in which the tonsils or tissue lesion are to be treated. An electrosurgical instrument having an active tissue treatment electrode and a return electrode connected to an electrosurgical generator is then inserted into the space, either along side the endoscope or through the endoscope's working channel. The generator is then operated to apply a radio frequency voltage between the active and return electrodes of the electrosurgical instrument, whereby a conduction path is formed between the active and return electrodes, at least partially through the saline, whereupon the active electrode is manipulated to debulk or otherwise treat the soft tissue lesion or enlarged tonsils and / or adenoids.

Medical devices, medical procedure trays, kits and related methods are provided for use to perform medical procedures that require access to the interior of a bone. The devices, trays and methods allow multiple use of non-sterile medical devices with sterile medical devices for performing medical procedures requiring sterile conditions. A coupler assembly, capable of releasably attaching to a non-sterile medical device at one end and releasably attaching to one or more sterile medical devices at another end, and further comprising a containment bag which allows maintaining sterility of a non-sterile medical device which may be used in conjunction with sterile medical devices and procedures. The devices, trays, kits and methods enable the performance of multiple medical procedures with a single insertion into bone. For example, a vertebral procedure such as a vertebroplasty may be performed along with biopsy and / or bone marrow aspiration procedures, thereby reducing patient trauma and costs.

A sterile surgical tray includes structure for receiving a plurality of surgical instruments, a pump fluid reservoir within the tray, a pump contained within the sterile tray and connected to the pump fluid reservoir, and a motor contained within the sterile tray and connected to the pump. Sterile surgical tray 10 also may include electrical input and output connectors attached to tray.

Methods, devices, and systems for a) revascularization and / or b) performing other medical procedures at vascular or non-vascular intracorporeal locations within a mammalian body. The methods generally comprise the formation of at least one extravascular passageway from a blood vessel to a vascular or non-vascular target location. In the revascularization methods the extravascular passageway is utilized for blood flow. In the medical procedure methods the extravascular passageway is utilized as a conduit for accessing or performing procedures at the vascular or non-vascular target location. Also disclosed are catheter devices and systems which are useable to form the extravascular passageways of the invention, as well as apparatus for modifying, maintaining and / or closing such extravascular passageways.

The invention relates generally to robotically controlled systems, such as medical robotic systems. In one variation, a robotic catheter system is configured with a sterile barrier capable for transmitting a rotary force from a drive system on one side of the barrier to surgical tool on the other side of the sterile barrier for performing minimally invasive diagnostic and therapeutic procedures. Modularized drive systems for robotics arc also disclosed herein.
