摘要： Double ended wire guides are manufactured so that either end, or both ends sequentially, may be inserted into a patient. The ends are different, so that the inventory requirements of wire guides are minimized. For example, a wire guide may have a straight end and an angled end, either end suitable for use on the patient. The wire guides may also differ in other characteristics, such as the stiffness or the diameters of the distal and proximal portions. The wire guide may also be stored in a package, the package including a fitting so that wetting solution may be injected into the package to wet the wire guide and prepare it for use.

摘要： A surgical trocar access sheath having a laterally expandable retention mechanism for percutaneous insertion through a body cavity wall. The expandable retention mechanism is positioned about the distal end of the sheath for retaining the access sheath within the body cavity. The access sheath has an inner elongated member cannula and an outer elongated member tube having a slick surface for ready insertion through a puncture site. The laterally expandable retention mechanism includes a plurality of strips extending and formed longitudinally in the outer tube. The retention mechanism has an expanded state and a retracted state. In the expanded state, the longitudinal strips extend radially from the outer elongated member tube to engage the interior surface of the body cavity wall. The expandable retention mechanism is actuated by sliding an actuating mechanism hub attached to the distal end of the outer elongated member tube against another hub fixedly attached to the inner elongated member cannula. To insert or retract the access sheath through the cavity wall of a patient, the physician squeezes the actuating mechanism hub against the fixed hub to collapse the longitudinal strips against the surface of the inner elongated member cannula. Once inserted, the actuating mechanism is released to expand the retention mechanism.

The device includes an elongated member including a material having an acoustic impedance different from that of the surrounding medium. The medium includes surrounding biological tissue or fluids surrounding the member when inserted into a passageway of the patient. The acoustic impedance of the elongated member is sufficiently different from the surrounding medium for enhancing an image produced in response to a sonic beam produced from imaging equipment. The elongated member also includes an interface layer of a high density metal of which the deposition on the base material of the member is ion beam assisted. The interface layer includes an outside surface having a plurality of particulate-type, discontinuous curved surfaces of partially spherical indentations formed therein or spheres extending therefrom. The difference between the acoustic impedances of the interface layer and the surrounding medium along with the discontinuous surfaces of the interface layer cooperate in response to a beam from sonic imaging equipment to significantly enhance the image of the medical device member.

摘要： A medical retrieval device 10 is disclosed comprising an elongated cylindrical member 11 that includes a continuum of a material 40, preferably a metal such as stainless steel or nitinol, that forms both the resilient grasping members 13 of retrieval basket 54, snare 26, or grasper forceps 23, and the proximal portion 21 or shaft of the device. The elongated cylindrical member can include a metal cannula 60 or solid rod 62 into which a series of laterally adjacent longitudinal slots 15 are cut or formed in the distal portion 37 of the elongated cylindrical member to form a plurality of resilient grasping members. These slots may be cut in a spiral configuration to produce a helical basket 69. The resilient grasping members in the original compact shape 17 are formed into an enlarged shape 18 to create a workspace volume 28 for the capture, manipulation and/or retrieval of an object within a patient. An external constraining device 14, such as an outer sheath, is used for introducing of the device and to compress the resilient grasping members over a calculus 24 or other object into a substantially closed position 30. An internal actuating member 29 within the passage 12 of the elongated cylindrical member can provide an alternative method of opening and closing the retrieval device. Using a small thin-walled cannula, retrieval devices of the present invention can fit through the accessory channel 46 of a small endoscope, such as an ureteroscope 44 while still having a sufficient lumen size to accommodate an ancillary treatment device 25 such as a standard 200 micron laser fiber or lithotripsy wire. The present invention also includes a retrieval device made from a plastic tube 32 having encased reinforcement wires 31. By removing all material 66 except the reinforcement wires from the distal portion of the elongated cylindrical member, the exposed wires can become the resilient grasping members of a basket or forceps.

摘要： A suture guide and, in particular, a urethral sound having interchangeable tips for placing sutures in the severed end of a body duct. The urethral sound includes an attachment mechanism having interconnection parts longitudinally rotatable when interconnected. The sound further includes an elongated member having a distal end portion including one of the interconnection parts. A plurality of interchangeable tips are provided each having a rounded distal end and a proximal end including the second interconnection part. Interchangeable tips are positioned at the distal portion of the elongated member and are longitudinally rotated thereat. Various tips include one or more apertures for placing sutures through, for example, a severed urethral stump created during a radical prostatectomy. Channels are also placed in a number of the tips to provide placement of individual sutures about the distal end of the severed stump as desired by the physician. The method includes positioning the urethral sound tip out the distal end of the duct with an aperture in the tip partially protruding from the duct. A suture thread is passed through the aperture and cut to form two equal length suture pieces on the opposite sides of the duct. The urethral sound tip is rotated to further position additional suture pieces about the severed end of the duct. The pieces are formed by cutting the suture extending through the aperture at the mid-point thereof.

摘要： Echogenic medical devices and methods of fabrication and of use are disclosed. The devices are adapted to be inserted into a patient. The device includes an elongated member including a material having an acoustic impedance different from that of the surrounding medium. The medium includes surrounding biological tissue or fluids surrounding the member when inserted into a passageway of the patient. The acoustic impedance of the elongated member is sufficiently different from the surrounding medium for enhancing an image produced in response to a sonic beam produced from imaging equipment. The elongated member also includes an interface including the outside surface of the member and a plurality of partially spherical indentations therein. Alternatively, generally spherical particles are attached to the surface of the member for producing the image in response to the sonic beam. Materials such as stainless steel, plastic, and glass are utilized in the manufacture of the medical device. The device may also include an echogenic body member including a composite material echogenically imageable in the patient. The composite material includes a matrix material with discrete sound reflective particles made from a material different from the matrix material and embedded therein. Several sound reflective particles are disclosed, one type of particle being a glass microsphere about 5 microns in diameter. The matrix material may be a plastic, and may be formed or extruded into devices such as catheters or other medical devices. The composite material may include different quantities of sound reflective particles by percent volume. Furthermore, a radiopaque material may be included in the composite material so the medical device is both ultrasonically imageable and radiographically imageable.
