摘要:
An interface system for interfacing between at least one endoscopic surgical instrument and a cable-controlled guide tube system. Various embodiments may include a tool docking assembly that is supportable relative to the cable-controlled guide system. The tool docking assembly may comprise one or more tool docking stations for retainingly supporting at least one endoscopic surgical instrument for selective pivotal travel about transverse axes. The system may further include cable attachment arrangements for coupling steering cables from the guide tube assembly to the various tool docking stations.

Methods and devices are provided for allowing a surgical instrument to be supported by a surgical support system configured to controllably guide the instrument to a desired position at surgical site. A surgical support system is provided that includes a guide port defining a pivot point about which a surgical instrument advance therethrough can pivot. The guide port, and hence the pivot point, can be located a distance above a tissue surface through which the instrument is advanced. Methods and devices are also provided for allowing insufflation of a body cavity without introduction of an insufflation fluid therein. A mechanical insufflation device is provided that includes an expandable distal member configured to selectively expand and unexpand to mechanically insufflate a body cavity. The mechanical insufflation device can optionally be used with the surgical support system.

Interface systems for interfacing between at least one endoscopic surgical instrument and a cable-controlled guide tube system. Various embodiments include at least one surgical tool docking assembly that is supportable relative to the cable-controlled guide tube system. The surgical tool docking assembly may comprise a cable drive assembly that is operably couplable to the cable-controlled guide system for applying control motions thereto. The surgical tool docking assembly may further comprise at least one tool docking station that is configured to support an endoscopic surgical instrument therein for selective pivotal travel about a first axis and a second axis. The tool docking stations cooperate with corresponding drive shafts for imparting rotary drive motions to the cable drive assembly. Various docking arrangements are disclosed for coupling the cable drive assembly to the cable-controlled guide tube assembly.

An intralumenal accessory tip for use with an inner sheath assembly during initial insertion of the inner sheath into a patient. The intralumenal accessory tip is removably attachable to the distal end of the inner sheath assembly and has passages therein to accommodate access tubes and endoscopic tools protruding from the inner sheath assembly. The intralumenal accessory tip may be attached to the distal end of the inner sheath assembly and both assemblies may be inserted into an overtube to permit the inner sheath assembly to be inserted into the patient. The inner sheath assembly may then be withdrawn out of the overtube and the intralumenal tip accessory removed therefrom.
摘要:
A guide system for accommodating, supporting and manipulating endoscopic tools. In various embodiments, the guide system includes a hollow outer sheath that may have a steerable distal end. The system may further include inner sheaths that are configured relative to the outer sheath to enable the inner sheaths to be inserted one at a time into the outer sheath and moved therein. The inner sheaths may be configured with different numbers, sizes and shapes of working channels for accommodating a variety of different endoscopic tools. The device may also be equipped with seals such that the inner sheath as well as the various endoscopic tools supported by the inner sheath may be manipulated within the body cavity while maintaining insufflation thereof.

An optical fiber for use with a laser device including a source of light energy, as well as a method of making same, where the optical fiber has a proximal end in communication with the light source and a distal end positionable at a treatment site. The optical fiber includes: a core having a proximal portion, a distal portion and a distal face proximate the distal end of the optical fiber, a layer of cladding radially surrounding the core from the core proximal portion to a designated point adjacent the core distal portion; a sleeve radially surrounding the cladding layer composed essentially of a predetermined type of material; and, a tip diffuser positioned at the distal end of the optical fiber.

摘要:
A method for repairing or modifying an area of a patient's anatomy that comprises directing at least a portion of a scanning beam assembly to an area of a patient's anatomy, applying a radiation-responsive agent to portion of the anatomy, and exposing the radiation-responsive agent to radiation directed onto the agent by the reflector to cause the agent to therapeutically interact with the site. The scanning beam assembly including a radiation source capable of emitting radiation, a reflector that receives the radiation from the radiation source to direct the radiation onto the anatomy, wherein the reflector oscillates in at least two directions to create a scan of the anatomy, a detector to detect radiation returned from the anatomy, and a controller to convert the detected radiation into a displayable anatomy image.
