Abstract
A tissue retrieval system can include a tissue retrieval bag with an elongate profile. The tissue retrieval bag can have a relatively large volume, but be rollable to a stowed configuration to fit in a relatively small diameter introducer. The tissue retrieval system can include one or more support arms coupled to the tissue retrieval bag, the support arms biased to position the tissue retrieval bag in an access position once deployed from the introducer. A tissue retrieval system can have a hybrid tissue retrieval bag including material properties that vary along the depth of the bag from an open end to a closed end. A tissue retrieval bag can be used in conjunction with an introducer, or as a stand alone tissue retrieval bag.
Claims29
A tissue retrieval system comprising:
- an elongate introducer having a hollow lumen formed therein;
- a tissue retrieval bag having a proximal end, a distal end, and an opening, the tissue retrieval bag having an elongate profile such that the opening is positioned adjacent the proximal end and the tissue retrieval bag comprises a distal portion extending from the opening towards the distal end of the tissue retrieval bag;
- and
- an actuator extending at least partially into the hollow lumen of the introducer;
- wherein the tissue retrieval bag is actuatable by the actuator from a stowed position in which the tissue retrieval bag is positioned within the hollow lumen of the introducer to an open position in which the tissue retrieval bag is substantially outside the introducer.
A tissue retrieval system comprising:
- an introducer sized and configured to be received in a trocar, the trocar having a diameter of less than about 7 mm, the introducer having a hollow lumen formed therein;
- a tissue retrieval bag having a volume of greater than approximately 100 mL, the tissue retrieval bag having a stowed configuration in which it is positionable within the hollow lumen of the introducer and an open configuration;
- and
- an actuator operable to advance the tissue retrieval bag from the stowed configuration within the introducer to the open configuration.
A tissue retrieval system comprising:
- an elongate tubular member having a passage formed therein, the elongate tubular member having a central longitudinal axis;
- a tissue retrieval bag having a stowed configuration in which the tissue retrieval bag is positionable within the passage of the elongate tubular member and an open configuration;
- and
- a support arm coupled to the tissue retrieval bag, the support arm biased in a first direction radially outward from the central longitudinal axis and a second direction transverse to the central longitudinal axis to position the tissue retrieval bag in the open configuration in an access position.
A tissue retrieval bag comprising:
- a film material having a proximal end, a distal end, and a rim defining an opening, the opening having a longitudinal axis;
- wherein the opening is positioned adjacent the proximal end and the tissue retrieval bag comprises an elongate profile defined by a distal portion of the tissue retrieval bag extending distally of the opening with respect to the longitudinal axis.
