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.
Claims27
A tissue retrieval device comprising:
- a retrieval bag having an open end and a closed end, the retrieval bag having a first portion adjacent the open end, a second portion adjacent the closed end, and a joint coupling the first portion to the second portion;
- wherein the first portion of the retrieval bag has a first compliance and the second portion of the retrieval bag has a second compliance, the first compliance being greater than the second compliance.
A tissue retrieval device comprising:
- a thin film bag having an open end and a closed end, the thin film bag comprising a first portion adjacent the open end and a second portion adjacent the closed end, the first portion and the second portion formed of a film material;
- wherein the first portion of the thin film bag has a first thickness and the second portion of the thin film bag has a second thickness, the first thickness being less than the second thickness.
A tissue retrieval device comprising:
- a tissue bag having an open end, a closed end, and an interior, the tissue bag comprising:
- a first portion adjacent the open end;
- and
- a second portion adjacent the closed end, the second portion comprising:
- a first layer;
- a second layer;
- a space between the first and second layer;
- and at least one vent fluidly coupling the space to ambient conditions exterior to the tissue bag.
A tissue retrieval device comprising:
- a tissue bag having an open end and a closed end, the tissue bag comprising a cuff portion adjacent the open end;
- a first body portion between the cuff portion and a second body portion;
- and the second body portion adjacent the closed end;
- wherein the cuff portion has a first compliance;
- the first body portion of the tissue bag has a second compliance and the second body portion of the tissue bag has a third compliance, the first compliance greater than the second compliance, and the second compliance greater than the third compliance.
