1. A medical device comprising:
- a propulsion member;
a flexible elongate member;
wherein the propulsion member is disposed at a distal end of the relatively flexible elongate member, and wherein the propulsion member is adapted to provide a pronulsion force distal of the flexible elongate member for advancing the propulsion member in a body lumen of patient; and
a working channel extending through the length of the flexible elongate member and through at least a portion of the propulsion member, the working channel sized for receiving a medical instrument for providing access to at least a portion of the body lumen through the propulsion member from a point outside the patient'"'"'s body.

Abstract
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.

10. A medical device comprising:
-
a capsule for introduction into a patient'"'"'s body lumen;
at least one electrode for electrically stimulating tissue to provide movement of the capsule;
an umbilicus attached to said capsule, said umbilicus of sufficient length to extend outside of said body lumen while said capsule is inside of said body lumen; and
at least one generally continuous working channel extending through the umbilicus and a least a portion of the capsule, wherein the working channel is adapted to provide access by a medical instrument to the lumen through the capsule from a point outside the patient'"'"'s body. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method of accessing tissue in a body lumen with a medical instrument, the method comprising the steps of:
-
providing a flexible elongate member;
providing a propulsion member at a distal end of the flexible elongate member;
providing a working channel extending through the flexible elongate member;
positioning the propulsion member in the body lumen;
providing a force distal of the flexible elongate member for advancing the propulsion member in the body lumen; and
directing a medical instrument from a point outside the body through the working channel in the flexible elongate member to access tissue in the lumen through an opening in the propulsion member. - View Dependent Claims (20, 21, 22, 23, 24)
