Abstract
The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to a tissue traction device, e.g., for an endoscopic procedure such as endoscopic tissue dissection. For example, a tissue traction device may include a traction band having a first end, a second end, a length therebetween and extending along a longitudinal axis. A first attachment member may extend from the first end of the traction band. A second attachment member may be associated with the body between the first end and the second end of the traction band. A third attachment member may extend from the second end of the traction band.
Claims20
A tissue traction device, comprising:
- a traction band extending along a longitudinal axis, having a first end and a second end, and stretchable to have a variable length between the first end and the second end;
- a first attachment member extending from the first end of the traction band and configured to be engaged with target tissue;
- a second attachment member configured to be engaged with anchoring tissue, and extending laterally from and being slidably disposed on the traction band between the first end and the second end of the traction band to selectively adjust a length of the device between the target tissue engaged by the first attachment member and the anchoring tissue engaged by the second attachment member;
- and
- a third attachment member extending from the second end of the traction band.
A tissue traction system, comprising:
- a tissue traction device comprising:
- a traction band having a first end, a second end, and a length therebetween extending along a longitudinal axis;
- a body extending circumferentially around the longitudinal axis of the traction band;
- a plurality of radially-outwardly extending protrusions positioned longitudinally along the body;
- a first attachment member extending from the first end of the traction band;
- a second attachment member extending from the traction band;
- and
- a third attachment member extending from the second end of the traction band;
- wherein at least one of the second attachment member or the third attachment member is shaped to be capable of being held in an engaged position on at least one of the plurality of protrusions on the body to adjust the length of the traction band.
A method of adjusting traction applied by a tissue traction device comprising a traction band having a first end and a second end and a body extending circumferentially around the longitudinal axis of the traction band between the first end and the second end and having a plurality of radially-outwardly extending protrusions positioned longitudinally therealong, the method comprising:
- coupling an attachment member with respect to one of the plurality of protrusions, the attachment member extending from the traction band at a position spaced apart from a first attachment member configured to be engaged with tissue at a first location and a second attachment member configured to be engaged with tissue at a second location spaced apart from the first location;
- and
- moving the attachment member to a protrusion closer to the first attachment member so that tension exerted by at least one of the first attachment member or the second attachment member is increased.
