    摘要： The filter device captures embolic material in a blood vessel and is placed in the blood vessel via a guide wire. The guide wire has a proximal end, a distal end and a stop near its distal end. The filter device includes an expandable frame of frame struts having a closed, radially compact form and an open, radially expanded form. The frame, in the radially expanded form, has frame struts forming a pair of facing frustoconical frame structures. Filter material is attached to one of the pair of frustoconical frame structures. In one embodiment, the filter material is a perforated membrane. The guide wire extends through the expandable frame and the expandable frame is freely movable over the guide wire (likewise, the guide wire is freely movable within the frame), both rotatably and longitudinally, except distally beyond the stop near the distal end of the guide wire. This mobility of the guide wire with respect to the expandable frame enables to guide wire to be guided by the operator through the blood vessel.

    摘要： An endoscopic bioptome includes a flexible coil having a lumen with an axially displaceable wire extending therethrough. The proximal ends of the coil and wire are coupled to a manual actuator for axially displacing one of the coil and wire relative to the other. The distal end of the coil is coupled to either a jaw assembly or a cylinder. The jaw assembly includes a pair of jaws each having a distal jaw cup having a proximal neck and a relatively narrow bent resilient arm. The distal end of the wire is coupled to the other of the cylinder or the jaw assembly. The cylinder is slidable over the jaw assembly. Axial movement of either the wire relative to the coil or vice versa moves the cylinder over the arms of the jaws and over the necks of the jaw cups, thereby forcing the jaw cups together in a biting action. In one embodiment, the axially displaceable wire is provided with a coaxial stopping band or sleeve which stops its movement as soon as the jaws close. In another embodiment, the cylinder is provided with an annular stopping crimp which limits relative displacement of the cylinder and the jaw assembly. In a third embodiment, the cylinder is provided with a radially inward flange and the coil is provided with a reduced diameter portion. In a fourth embodiment, the jaw cups are provided with outer surface steps. In all of the embodiments, the limitation of displacement has the effect of limiting the cutting force applied to the jaws.

    摘要： A flexible microsurgical instrument having a distal portion which is ground to a reduced diameter and covered with a stiffening sleeve is disclosed. The instrument includes a proximal actuating handle coupled to a flexible coil containing at least one control wire and a distal end effector coupled to the distal end of the coil and the control wire. A distal portion of the coil is ground to a reduced outer diameter and thus a reduced thickness. The stiffness of the distal portion is enhanced by placing a stiffening sleeve over the ground distal portion. The stiffening sleeve has a thickness substantially equal to one half the difference between the reduced diameter of the ground distal portion and the diameter of the remainder of the coil so that the outer diameter of the coil is substantially constant along its length when the stiffening sleeve is in place.

    摘要： A safety catheter includes a flexible, multi-lumen shaft having an outer diameter, a distal tip, a proximal catheter end with a drain end and a proximal inflation end. The multi-lumen shaft defines a drain lumen, a distal hollow balloon portion, at least one inflation lumen, and a drainage port. A hollow stretch valve is coaxially disposed in the drainage lumen, has a fixed portion within the drainage lumen just proximal of an increased stretching portion, and prevents fluid from passing through the drainage port in a steady state. The stretch valve has a sliding portion slidably disposed within the drainage lumen such that, in a stretched state when the proximal catheter end is stretched, the sliding portion slides within the drainage lumen to permit fluid to pass through the balloon drainage port and/or inner wall of the catheter.

    摘要： A retractor for manipulating an object includes a body having proximal and distal ends and a retraction device with a head connected to the distal end of the body, a connector movably disposed in the body, and flexible needles of a shape memory material having a memory shape. The needles are connected to the connector and each have a distal tip. The memory shape of the needles include a portion with an arcuate shape biasing the needles in a memory direction out and away from the head and toward the body to position the distal tip of each of the needles closer to the body when the needles are fully extended out of the head than when the needles are only partially extended out of the head. An actuation device is connected to the proximal end of the body and operatively connected to the connector through the body, the actuation device, upon actuation thereof, moves the connector to selectively extend the needles out of the head in different directions and withdraw the needles into the head.

    摘要： A disposable ultrasonic surgical handle connectable to an ultrasonic waveguide, a battery, and an ultrasonic-movement-generator assembly includes a first handle body portion defining therein an aseptically sealable battery-holding compartment shaped to receive the battery therein, a second handle body portion connected to the first handle body portion, and an electrical couple. The second handle body portion has a waveguide attachment dock exposed to the environment and an ultrasonic-movement-generator assembly dock exposed to the environment and shaped to connect the ultrasonic waveguide in the waveguide attachment dock to the ultrasonic-movement-generator assembly through the second handle body portion. The electrical couple is operable to connect a battery within the battery-holding compartment to the ultrasonic-movement-generator-assembly when the ultrasonic-movement-generator assembly is docked at the ultrasonic-movement-generator assembly dock.
