Abstract

A tissue retrieval device includes a tubular member, an expandable member, and a tissue retrieval bag. The introducer tube is sized to be inserted into a patient through a trocar. The bag may be selectively opened by the expandable member within the patient. The bag may receive a tissue specimen and be withdrawn from the patient. The bag may be manipulated for packing within the tubular member in a variety of ways. Manipulation of the bag may include folding the bag about axes that are perpendicular to or parallel to the tubular member; rolling the bag about axes that are perpendicular to or parallel to the tubular member; or wrapping the bag about the expandable member, wrapping the bag about a rod, or twisting the bag at a position distal to the expandable member. The tubular member may comprise an environmentally responsive capsule.

Dependent claims

A method of loading a retrieval bag within a specimen retrieval instrument, wherein the specimen retrieval instrument comprises a tubular member, a rod positioned within the tubular member, an expandable member, and a retrieval bag, wherein the tubular member has a distal end and a proximal end, wherein the tubular member defines a central longitudinal axis, wherein the retrieval bag is secured to the expandable member, wherein the tubular member is configured to contain the expandable member and the retrieval bag, wherein the tubular member is configured to hold the expandable member in a compressed state to contain the expandable member, wherein the expandable member is configured to open the retrieval bag when the expandable member is expanded to an expanded state, wherein the rod comprises a distal end and a proximal end, wherein the expandable member is located at the distal end of the rod, the method comprising:

(a) reducing the size of the retrieval bag to create a packed retrieval bag, wherein the act of reducing the size of the retrieval bag comprises bending the expandable member about a second axis to position a distal portion of the expandable member proximally in relation to the distal end of the rod and wrapping the retrieval bag about one or both of the rod and the expandable member;
and
(b) positioning the packed retrieval bag and the expandable member within the tubular member, wherein the expandable member is in a compressed state within the tubular member, wherein the expandable member extends along the central longitudinal axis of the tubular member.

A method of loading a retrieval bag within a specimen retrieval instrument, the method comprising:

(a) providing a specimen retrieval instrument, wherein the specimen retrieval instrument comprises:
(i) a tubular member defining a central longitudinal axis,
(ii) a rod comprising a distal end, wherein the rod is located within the tubular member,
(iii) an expandable member extending distally from the rod, and
(iv) a retrieval bag, wherein the retrieval bag has an open top end secured to the expandable member and a closed bottom end, wherein the tubular member is configured to contain the expandable member and the retrieval bag, wherein the tubular member is configured to hold the expandable member in a compressed state to contain the expandable member, wherein the expandable member is configured to open the retrieval bag when the expandable member is expanded to an expanded state;
(b) bending the expandable member to position the distal end of the expandable member proximal to the distal end of the rod;
(c) packing the retrieval bag, wherein the act of packing the retrieval bag comprises wrapping at least a portion of the retrieval bag around the expandable member and;
and
(d) positioning the packed retrieval bag and the expandable member within the tubular member, wherein the expandable member extends along the central longitudinal axis, wherein the act of positioning the packed retrieval bag and the expandable member within the tubular member further comprises compressing the expandable member.

A method of loading a retrieval bag within a specimen retrieval instrument, wherein the specimen retrieval instrument comprises a tubular member having a central longitudinal axis, an expandable member, a rod within the tubular member, and a retrieval bag, wherein the expandable member is distal in relation to the rod, wherein the retrieval bag comprises an open end secured to the expandable member and a closed end, wherein the tubular member is configured to contain the expandable member and the retrieval bag, wherein the tubular member is configured to hold the expandable member in a compressed state to contain the expandable member, wherein the expandable member is configured to open the retrieval bag when the expandable member is expanded to an expanded state, the method comprising:

(a) reducing the size of the retrieval bag to create a packed retrieval bag, wherein the act of reducing the size of the retrieval bag comprises:
(i) bending the expandable member to position the distal end of the expandable member proximal to the distal end of the rod, and
(ii) wrapping at least a portion of the retrieval bag around one or both of the expandable member and the rod such that the closed end of the retrieval bag is proximal in relation to the distal end of the rod yet on the opposite side of the rod as the expandable member;
and
(b) positioning the packed retrieval bag and the expandable member within the tubular member, wherein the expandable member is in a compressed state within the tubular member, wherein the expandable member extends along the central longitudinal axis of the tubular member.
