A medical device for performing medical procedures inside a lumen (such as the GI tract) of a patient is provided. The device includes an elongate flexible member which can be advanced along a track. The track can include a loop portion which can be advanced ahead of the elongate flexible member. The distal end of the flexible member can include a camera, light source, vacuum opening, and a working channel for receiving medical instruments.

Medical device with track and method of use

A method is described of inserting guide wires into a lumen, for example into the human gastrointestinal tract. A guide wire structure is employed which comprises at least two guide wires each having a leading end portion which terminates in a leading end, the guide wires being connected to one another by a junction at or adjacent their leading ends, the guide wires have a first position in which the leading end portions are substantially parallel to one another, a second position in which the leading end portions are curved, and a third position in which at least one of the leading end portions forms a loop. The guide wire structure is steered through the gastrointestinal tract by selectively advancing or retracting a single guide wire or advancing more than one guide wire simultaneously, according to the path which is required to be followed.

Guide wire structure for insertion into an internal space

A medical device for performing medical procedures inside a lumen (such as the GI tract) of a patient is provided comprising a capsule, a cable, and a propulsion means. The cable can have one end anchored to the patient, and can extend from this anchored portion to the capsule. The cable can include a loop forward (distal) of the capsule in the GI tract. The propulsion means is operably connected to the cable to vary the length of cable between the anchored end and the capsule, so that the capsule is repositioned inside the GI tract of the patient.

Locally-propelled, intraluminal device with cable loop track and method of use

A tissue ablation system is described. The tissue ablation system can include a plurality of electrodes, a viewing window between adjacent electrodes, illuminating elements, and an image sensor. The image sensor can be a CMOS device.

Endoscopic ablation system with a distally mounted image sensor

A medical device having a laminate elongate hollow member is disclosed. The laminate member provides torsional stiffness for controlling positioning of the distal end of the device, and provides bending flexibility for assisting in insertion of the device in the patient's esophagus or other body lumen.

Medical device with improved wall construction

The present invention provides apparatus and method for providing access of a medical instrument, such as a surgical instrument, from a point outside the patient's body to a point within a body lumen, such as a portion of the Gastro-intestinal tract. A self propelled device, such as a capsule having electrodes for providing contraction of lumen tissue, can be positioned within the body lumen at a desired location. The medical instrument can be directed through a working channel associated with the capsule to access the body lumen tissue through the capsule.
