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 The bag may receive a tissue specimen and be withdrawn from the patient.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.

Abstract: A surgical needle includes a pair of ends, a mid-region extending between the ends, and at least one grasping feature configured for grasping by a suturing instrument. An end of a suture is secured to the mid-region of the needle in a manner such that the end of the suture defines an oblique angle with at least part of the centerline defined by the mid-region of the needle. The end of the suture may be disposed in a hollow portion of the needle. The grasping feature may include a notch such as a scallop. The suture may be pivotally coupled with the needle via a ball or pin. The needle may have one or more sharp points. The sharp point may include three converging cutting edges, at least two planar surfaces bounded by the three cutting edges, and a rounded surface bounded by two of the three cutting edges.

Abstract: A tissue retrieval device includes an introducer tube and a tissue retrieval bag. The introducer tube is insertable into a patient through a trocar. The bag may be selectively exposed at the distal end of the introducer tube, receive a tissue specimen, and be withdrawn from the patient. The bag includes a plurality of folds allowing the bag to transition from a folded configuration to an unfolded configuration. The folds may extend along a length of the bag transverse to the introducer tube; or along a length of the bag parallel to the introducer tube. The folds may extend about a perimeter of the bag, such as a circumference of the bag, and may be spaced apart along a length of the bag transverse to the introducer tube. The folds may be formed by petals that provide the bag with a generally spherical configuration when the bag is unfolded.

The tissue retrieval bag may be selectively exposed at the distal end of the introducer tube within the patient. The tissue retrieval bag may receive a tissue specimen and be withdrawn from the patient. The tissue retrieval bag may include an inflatable portion. When inflated, the inflatable portion may extend the tissue retrieval bag from a contracted configuration to an expanded configuration. The inflatable portion may substantially seal a tissue specimen within the tissue retrieval bag. The tissue retrieval bag may me formed of an environmentally sensitive material such that the size of the tissue retrieval bag expands when the tissue retrieval bag is exposed within the patient.
