    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： According to an aspect of the invention, an indwelling catheter is provided which comprises a catheter shaft. The catheter either comprises a light source or is adapted to receive light from a light source, and is configured such that light is transmitted from the light source into the catheter shaft. Moreover, the catheter shaft is formed of a polymeric material that transmits a quantity of light from the light source that is effective to inactivate microorganisms on a surface of the catheter shaft upon activation of the light source. For example, the light may inactivate the microorganisms directly or in conjunction with a photosensitizer. According to another aspect of the invention, a sterilization method is provided, which comprises activating the light source while the catheter is inserted in a subject.

    摘要： Methods and devices are provided for delivering and affixing tissue replacements. In one embodiment, a tissue scaffold can be delivered into a patient through a cannula to a cavity formed at a defect site in tissue, e.g., cartilage. A delivery shaft can be used to deliver the scaffold through the cannula, and a loading device can help load the scaffold onto the delivery shaft. A delivery guide device can position and temporarily hold the scaffold within the cavity. The delivery guide device can guide one or more surgical instruments to the scaffold to affix the scaffold within the cavity, e.g., to bone underlying the scaffold, using at least one securing mechanism.
