Claims20
A medical device configured to protect a body opening, the medical device comprising:
- a sleeve having a proximal end and a distal end;
- a proximal ring attached to the proximal end of the sleeve;
- and
- a guard assembly located a distal end of the sleeve.
A medical device configured to protect a body opening, the medical device comprising:
- a sleeve having a proximal end and a distal end;
- and
- a guard assembly located at the distal end of the sleeve, wherein the guard assembly includes a guard ring and a plurality of petals, wherein the plurality of petals are movably connected to the guard ring.
A medical device configured to protect a body opening, the medical device comprising:
- a sleeve having a proximal end and a distal end;
- a guard assembly having a plurality of petals;
- and
- a plurality of pockets formed at the distal end of the sleeve, wherein each petal of the plurality of petals is secured within a corresponding pocket of the plurality of pockets.
A medical device configured to protect a body opening in a deployed configuration, the medical device comprising:
- a sleeve having a proximal end and a distal end;
- a proximal ring attached to the proximal end of the sleeve;
- a guard assembly located at the distal end of the sleeve;
- and
- a distal ring, wherein the distal ring is movable relative to the sleeve and the guard, and wherein the distal ring is disposed at a distal-most end of the guard assembly in the deployed configuration.
A method of retracting a body opening, the method comprising:
- inserting a medical device into the body opening, the medical device including a sleeve, a proximal ring attached to a proximal end of the sleeve, a guard assembly attached to a distal end of the sleeve, and a distal ring;
- moving the distal ring from a first position, wherein at least a portion of the distal ring is disposed outside the body, to a second position, in which the distal ring is disposed entirely inside the body;
- and
- moving the proximal ring distally to urge a portion of the sleeve and guard radially outwardly within the body opening.
A medical device configured to protect a body opening, the medical device comprising:
- a sleeve having a proximal end and a distal end;
- a proximal ring attached to the proximal end of the sleeve;
- a distal ring received about a portion of the sleeve;
- and
- a guard assembly located a distal end of the sleeve, the guard assembly including
- a guard ring
- a plurality of petals movably coupled to the guard ring;
- and
- a plurality of petal pockets receiving the plurality of petals.
