摘要： A medical introducer includes an elongated tubular member having a proximal end, a distal portion, and a central lumen extending from the proximal end to a distal port in the distal portion. A frame structure is coupled to the distal portion of the elongated tubular member, where frame structure supports the distal portion of the elongated tubular member in a tapered shape and alternatively in a non-tapered shape. The elongated tubular member may include a rigid outer tube and a rigid inner tube carried in an interior lumen of the outer tube. The distal portion is typically a reinforced elastomeric tubular extension of the outer tube, and the reinforced elastomeric tubular extension may have a conical shape.

摘要： A deployable and flexible tooltip camera is provided for integration within a shaft of an endoscopic tool. The tooltip camera includes a camera mounted to a distal tip of a curved tube which is capable of rotational and translational movement to provide a wide field of view of a tooltip of the endoscopic tool during an endoscopic procedure. The tube retains its curved shape when in use to provide a unique perspective view of the tooltip, but can then be withdrawn into a shaft of the endoscopic tool such that the entire tooltip camera and tube are retained within the shaft of the endoscopic tool and can pass through a cannula. The curved tube may be formed of a super-elastic memory alloy like Nitinol and pre-shaped into an s-curve using a two-step heat treatment process to attain the necessary curvature, and further laser-patterned with holes to attain the necessary flexibility.

摘要： A medical device may comprise a sheath configured to be inserted into a body lumen of a patient. A distal end of the sheath may include an elevator for changing an orientation of a medical device. A handle may include an actuator. The actuator may be operably connected to the elevator. Activation of the actuator may cause movement of the elevator. An engaging portion may, in at least one configuration of the handle, protrude from a surface of a handle body toward the actuator. A force exerted by the user on at least one of the actuator or the engaging portion may cause the handle to transition between (a) a first configuration in which the engaging portion interacts with the actuator to inhibit movement of the actuator relative to the engaging portion and (b) a second configuration in which the actuator is movable relative to the engaging portion.

摘要： A catheter for use in a patient's heart, especially for mapping a tubular region of the heart, has a catheter body, a deflectable intermediate section and a distal a mapping assembly that has a generally circular portion adapted to sit on or in a tubular region of the heart. A control handle of the catheter allows for single-handed manipulation of various control mechanisms that can deflect the intermediate section and contract the mapping assembly by means of a deflection control assembly and a linear control assembly. The deflection control assembly has a deflection arm and a rocker member. The linear control assembly has a linear control member, an inner rotational member and a cam. A pair of puller members are responsive to the deflection control assembly to bi-directionally deflect the intermediate section. A third puller member is responsive to the linear control assembly to contract the generally circular portion of the mapping assembly.

摘要： An apparatus for performing surgical procedures is disclosed including a flexible entry guide tube and a first steering device. The guide tube has one or more lumens extending along its length from a proximal end to substantially at or near a distal end. At least one of the one or more lumens is an instrument lumen with open ends to receive a flexible shaft of a surgical tool. The first steering device is insertable into the instrument lumen to shape the guide tube as it is inserted through an opening in a body and along a path towards a surgical site. The apparatus may further include a flexible locking device to couple to the flexible entry guide tube and selectively rigidize the guide tube to hold its shape. The guide tube may be steered by remote control with one or more actuators.

摘要： The present invention is directed to a tool having a wrist mechanism that provides pitch and yaw rotation in such a way that the tool has no singularity in roll, pitch, and yaw. In one embodiment, a minimally invasive surgical instrument includes an elongate shaft haying a working end, a proximal end, and a shaft axis between the working end and the proximal end; and an end effector. A wrist member has a flexible tube including an axis extending through an interior surrounded by a wall. The wall f the flexible tube includes a plurality of lumens oriented generally parallel to the axis of the flexible tube. The wrist member has a proximal portion connected to the working end of the elongate shaft and a distal portion connected to the end effector. A plurality of actuation cables have distal portions connected to the end effector and extend from the distal portion through the lumens of the all of the wrist member toward the elongate shaft to proximal portions which are actuatable to bend the wrist member in pitch rotation and yaw rotation.
