    摘要： Various methods and devices are provided for penetrating tissue. In one embodiment, a tissue-penetrating device is provided and includes a flexible hollow elongate shaft having a tissue-penetrating tip at a distal end thereof, and a plunger disposed within the tissue-penetrating tip. The plunger can be movable relative to the tissue-penetrating tip between a distal position in which the plunger is distal of the tissue-penetrating tip to prevent tissue penetration, and a proximal position in which the plunger is proximal of the tissue-penetrating tip to allow the tip to penetrate tissue. The plunger can be adapted to move from the distal position to the proximal position when the plunger is advanced into a tissue surface. The device can also include a biasing element coupled to the plunger that can be adapted to bias the plunger to the distal position. The biasing element can be coupled between a distal end of a stylet that extends through the hollow elongate shaft, and a proximal end of the plunger.

    摘要： Disclosed herein are devices and methods for forming multidirectional cuts in tissue. The tissue cutting devices disclosed herein generally include a flexible elongate member with at least first, second, and third wires that are at least partially constrained within or along a portion of the member. A distal portion of the wires is anchored on or within a portion of the elongate member. When tension is applied to at least one of the wires, such as by an actuator at a proximal end of the device, the elongate member bows while an unconstrained portion of the wire becomes exposed relative to the adjacent portion of the elongate member, assuming a tissue-cutting configuration.

    摘要： A medical instrument includes a medical-end-effector-associated member and resiliently flexible first, second and third elongate members. The medical-end-effector-associated member has a rigid portion positionable within a patient. The first, second and third elongate members each have a proximal end portion and a distal end portion. The distal end portions of the first, second and third elongate members are attached to the rigid portion of the medical-end-effector-associated member. Relative lengthwise translation of the proximal end portions of the first, second and third elongate members articulates the rigid portion of the medical-end-effector-associated member.

    摘要： An intubation system is provided for use with an endoscope. The intubation system includes a guide apparatus having a track that is adapted to be associated with the endoscope such that bending of the track is substantially decoupled from bending of the endoscope. The intubation system also includes a positioning device having a first coupling member on the distal end and an intubation device having a second coupling member on the proximal end. The intubation device and the positioning device each include a mating member that is adapted to slidingly engage the track external of the endoscope, whereby the first and second coupling members may be releasably attached together.

    摘要： An intubation device is provided for use with a guide apparatus having a track that is adapted to be associated with an endoscope such that bending of the track is substantially decoupled from bending of the endoscope. The intubation device includes an elongated, flexible tube and a mating member attached to the tube and adapted to slidingly engage the track external of the endoscope. The intubation device further includes a tissue bolster disposed on the proximal portion of the tube and changeable between a collapsed and an expanded configuration. The tube is positionable inside the upper gastrointestinal tract of a patient such that the proximal end of the tube is externalized through the gastric and abdominal walls of the patient, and wherein the tissue bolster is securable against the inner gastric wall when the tissue bolster is in the expanded configuration.
