    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.

    摘要： A tissue snare comprises an elongated member having a distal end and a loop formed of a shape memory material, the loop including a tissue receiving interior opening and being connected to the distal end of the elongated member, properties of the shape memory material being selected so that, when a temperature of the loop exceeds a critical temperature thereof, the loop constricts from an expanded state to a constricted state. A method of treating tissue comprises placing a loop of a snare around a portion of tissue to be treated while the loop is in an expanded configuration, the loop being formed of a shape memory material having a critical temperature so that, when a temperature of the loop is above the critical temperature, the loop transitions from the expanded configuration to a constricted configuration in combination with transitioning, after the loop has been placed around the portion of tissue to be treated, the loop from the expanded configuration to the constricted configuration to tighten the loop around the portion of tissue to be treated.

    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 catheter assembly and method for internally anchoring a catheter in a patient. According to one embodiment, the catheter assembly includes a catheter, a tubular fitting coupled to one end of the catheter, and an internal bolster coaxially mounted around the tubular fitting. The tubular fitting has a waist portion, and the internal bolster is secured thereto by a snap-fit. To internally anchor the catheter in a patient, one inserts the end of the catheter to which the fitting is coupled into the patient and then, while the fitting and its coupled end of the catheter are within the patient, inserts the internal bolster over the fitting until it snap-fits into place over the waist portion, thereby internally anchoring the catheter within the patient.
