摘要： The present invention provides an apparatus and method for an ultrasonic medical device with improved visibility in imaging procedures. A medical device comprises an elongated probe having a material of high radiopacity at an at least one predetermined location of the probe wherein the material of high radiopacity is capable of withstanding series of vibrations of the elongated probe. The material of high radiopacity allows the elongated probe to be visualized in imaging procedures when the probe is inserted into a body. The present invention provides a method of improving the visibility of an ultrasonic medical device during a medical procedure by engaging a material of high radiopacity to a small diameter elongated probe wherein the material of high radiopacity engages the probe at an at least one predetermined location.

摘要： A clot and foreign body removal device is described which comprises a catheter with at least one lumen. Located within the catheter is a clot capture coil that is connected to an insertion mandrel. In one embodiment, the clot capture coil is made out of a solid elastic or superelastic material which has shape memory, preferably nitinol. The elasticity or superelasticity of the coil allows it to be deformed within the catheter and to then reform its original coil configuration when the coil is moved outside of the catheter lumen. In another embodiment the coil is a biphasic coil which changes shape upon heating or passing an electric current. Once the coil configuration has been established, the coil can be used to ensnare and corkscrew a clot in a vessel. A clot is extracted from the vessel by moving the clot capture coil and catheter proximally until the clot can be removed or released into a different vessel that does not perfuse a critical organ. Foreign bodies are similarly captured by deploying the coil distal to the foreign body and moving the clot capture coil proximally until the foreign body is trapped within the coil. By removing the device from the body, the foreign material is also removed.

摘要： The invention is directed to a grasping device and system and the method of using the device and system for capturing a thromboembolism and other objects or masses within a patient's body lumen, particularly from within a patient's cerebral blood vessels. The grasping device has an elongated core member with a grasping assembly of arms on the distal end of the core member which have an expanded and a contracted configuration. The expanded configuration permits the arms to surround an object such as a thrombus or clot and a contracted configuration to grasp or capture the object. The distal ends of the arms are provided with object grasping members such as one or more teeth to facilitate the capture and removal of the object. A delivery catheter and a shorter guide catheter aid in delivering the grasping device to the desired intravascular location within the patient.

摘要： A method and apparatus for removing plaque, fatty deposits, and other occlusions from blood vessels using ultrasonic energy. The method and apparatus has particular application in removing plaque from the carotid artery in a non-thermal manner. The apparatus is designed to have as small a cross-sectional profile as possible, therefore allowing the apparatus to be used in a minimally-invasive manner. As a result, the apparatus can be used in both surgical and outpatient treatment with minimal post-operative complications and minimal damage to areas other than the area of treatment. An ultrasonic probe may include aspiration channels on its outer surface. An aspiration sheath may surround the ultrasonic probe, such that the location of an aspiration port may be varied axially relative to the ultrasonic tip.

摘要： A medical retrieval device includes a handle and a hollow sheath extending forward from the handle. A slide is attached to the handle for longitudinal movement along a path between a rearward location and a forward location. A rotary actuator having an axis of rotation generally transverse to the path of movement of the slide is mounted to the slide for rotational movement with respect thereto. A basket having at least three legs is located at a forward end of the sheath. Two adjacent basket legs are connected to a first side of the rotary actuator, and the remaining basket legs are connected to the opposite side of the rotary actuator such that rotation of the rotary actuator displaces the two legs in a first direction with respect to the sheath and displaces the remainder of the legs in a direction opposite the first direction. The basket is retracted within a forward portion of the sheath when the slide is in the rearward location, and the basket is extended forward of the forward end of the sheath when the slide is in the forward location. Thus longitudinal movement of the slide extends and retracts the basket, and rotation of the rotary actuator articulates the basket.

摘要： A surgical apparatus for removing deposits from an interior of a vessel comprising a rotatable shaft and a rotatable tip mounted to the rotatable shaft which is rotatable about its longitudinal axis upon rotation of the shaft to remove deposits from the interior of the vessel. The tip has a distal portion, a proximal portion and an intermediate portion between the distal and proximal portions. The intermediate portion is defined by a plurality of transverse cross-sectional areas, wherein each transverse cross-sectional area defines first and second axes substantially perpendicular to each other to define a width dimension along a first axis and a height dimension along the second axis. The height dimension is greater than the width dimension.

At least part of the eccentric enlarged diameter section has a tissue removing surface. The eccentric enlarged diameter section of the drive shaft has a center of mass and/or geometric center spaced radially from the rotational axis of the drive shaft, facilitating the ability of the device to open the stenotic lesion to a diameter substantially larger than the outer diameter of the enlarged diameter section.
