Abstract
The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to traction systems, and methods of use thereof, for endoscopic procedures such as tissue dissection. For example, a traction system may include a filament extendable along an outer surface of an endoscope with a distal end of the filament attachable to a medical device engaged with a target tissue of a body lumen.
Claims20
A system for use with a flexible elongate tubular member extendible within and through a patient and having a working channel therethrough, the system comprising:
- a cap attachable to a distal end of the flexible elongate tubular member and having a working channel extending therethrough, the cap including a lumen coextensive with the working channel of the flexible elongate tubular member;
- a first guide attached to an outer surface of the cap;
- and
- a first filament extendable through the first guide and along an outer surface of the flexible elongate tubular member and the cap such that the filament and the outer surface of the flexible elongate tubular member may contact each other.
A system for performing an endoscopic procedure within a patient, the system comprising:
- a first guide extendable along at least a portion of an outer surface of an endoscope, the endoscope having a working channel extending therethrough with an open distal end through which an endoscopic instrument is extendable;
- and
- a first filament having a distal end and a proximal end and extendable from the distal end at the open distal end of the endoscope, directly through the first guide, and proximally and directly along an outer surface of the endoscope to outside the patient to the proximal end to be controlled by a physician.
A method, comprising:
- extending a first filament along an outer surface of a flexible elongate tubular member from a distal end of the flexible elongate tubular member, through a first guide mounted on an outer surface of the flexible elongate tubular member, and along an outer surface of the flexible elongate tubular member without a further element between the first filament and the first guide or the outer surface of the flexible elongate tubular member;
- coupling a distal end of the first filament to target tissue;
- and
- retracting the first filament via a proximal end of the first filament to apply traction to the target tissue.
