    摘要： An environmentally sensitive hydrogel material swells or collapses in response to a parameter such as pH level associated with consumption of food by a patient. This swelling or collapsing is harnessed to treat morbid obesity or some other condition of the patient. The swelling or collapsing of the hydrogel may be used to tighten a gastric band or gastric valve when the patient starts eating; then loosen the band or valve when the patient is between meals. The swelling or collapsing of the hydrogel may also be used to increase the size of a space occupying device in the patient's stomach when the patient starts eating; then decrease the size of the space occupying device when the patient is between meals. The swelling or collapsing of the hydrogel may also be used to selectively restrict the absorption of nutrients within a patient's gastrointestinal tract, such as in the duodenum.

    摘要： A tissue retrieval device includes a tubular member, one or more frame members, and a tissue retrieval bag. The tubular member is insertable into a patient through a trocar to open the bag within the patient to receive a tissue specimen. The internal capacity provided by the bag may vary based on the longitudinal position of the frame members. The bag may be stretchable to increase its internal capacity. At least one sidewall of the bag may include one or more reinforcement members, which may influence the way in which the bag stretches by restricting stretching of the bag in one or more directions while freely permitting stretching of the bag in one or more other directions. Part of the undeployed bag may be contained in a recess formed in the side of the tubular member, with a removable cap being positionable over the undeployed bag and recess.

    摘要： Methods and devices are provided to improve access to a surgical site during surgical procedures. In one exemplary embodiment a surgical access device is provided having a cannula, a cannula base, and a retractor. The cannula base is configured to couple both to the retractor and the cannula to provide access to a surgical site. The cannula can be removably and replaceably coupled to the cannula base. Optionally, the cannula base can be removably and replaceably coupled to the retractor. As desired, the cannula can be decoupled from the cannula base, which can allow for an object to be removed from the surgical site and/or for the cannula, or another cannula to be attached to the cannula base that remains in place to maintain access to the surgical site. Exemplary methods for accessing a surgical site are also provided.
