    摘要： A method includes identifying an area of interest within a gastrointestinal lumen based on a virtual imaging modality. Energy is applied using an external energy source directed at the area of interest sufficient to disrupt at least a portion of an undesired tissue. In another embodiment, the method includes introducing a contrasting agent into a gastrointestinal lumen. The gastrointestinal lumen is imaged with an imaging device. An area of interest within the gastrointestinal lumen is identified, where the area of interest is indicated by the contrasting agent. Energy is applied using an external energy source directed at the area of interest to disrupt at least a portion of a tissue located at the area of interest. The disrupted tissue is removed from the gastrointestinal lumen.

    摘要： A medical catheter assembly and method of using the same. In one embodiment, the assembly comprises a gastrostomy feeding tube having a proximal end, a distal end and a longitudinal bore, the distal end being shaped to include an internal bolster, the internal bolster having an anchoring state and a non-anchoring state. A suture extends from the internal bolster through the longitudinal bore to exit the tube at its proximal end, proximal displacement of the suture maintaining the internal bolster in its anchoring state. A protective sleeve made of a rigid material is removably insertable into the tube through its proximal end, the suture being inserted through the protective sleeve. The protective sleeve, when inserted into the tube, serves to protect the suture from being cut when the tube is cut to a desired length after having been implanted in a patient.

    摘要： An apparatus includes an elongate body including a proximal end portion and a distal end portion and configured to be at least partially inserted into a body cavity. The elongate body defines a first passageway and a second passageway. The first passageway is configured to communicate fluid from the distal end portion in a first direction, and the second passageway is configured to communicate material from outside of the elongate body into the distal end portion in a second direction opposite the first direction and includes at least one port. An actuator is coupled to the elongate body and is configured to guide the distal end of the elongate body to an area of interest identifiable by a virtual colonoscopy.
