摘要： A hand-operated inflator device for inflating the expander on a balloon-type catheter. It comprises a molded plastic housing for retaining a syringe tube therein for containing an inflation fluid. The housing also includes an internally threaded surface. A syringe plunger having an internal longitudinal bore and a longitudinal slot formed through the wall thereof has a piston mounted on the distal end for insertion into the syringe body. Fitted into the longitudinal slot is an externally threaded member which can be raised and lowered in a radial direction by manipulation of a manuable actuable means positioned in the longitudinal bore of the plunger. When the externally threaded member is raised, its teeth mesh with the teeth on the internally threaded annular surface of the housing, but when lowered, the threaded surfaces are disengaged. When the two are engaged, the piston is advanced in the syringe tube by rotating the plunger. When the two are disengaged, the plunger may be advanced by longitudinal force applied to the end of the plunger.

摘要： A guidewire for placement within a blood vessel for penetrating an occlusion therein. The guidewire comprises a length of flexible wire having a lumen extending therethrough. The distal end of the guidewire is generally arcuate and has a diameter greater than that of the wire immediately proximal thereto. A flexible stylet substantially the same length as the flexible wire may be disposed within the lumen of the wire. In operation, the arcuate distal end of the guidewire is positioned in the blood vessel against an occlusion, and a dottering action is thereafter provided whereby the arcuate distal end of the guidewire repeatedly impinges on the occlusion until penetration of the occlusion occurs.

摘要： To facilitate certain surgical procedures, a flexible endoscope may more readily be passed through body vessels and tubular organs, especially when those organs assume a tortuous path. However, a difficulty arises in steering a flexible endoscope through internal body orifices. In accordance with the present invention, a rigid introducer is used in combination with the flexible endoscope to facilitate targeting of such an orifice and once the distal end of the introducer is made to enter the orifice, the flexible endoscope can be advanced through the introducer and there beyond to the point in the body where an item of interest is to be viewed.

摘要： A blood pressure monitoring catheter for use in a Monorail.TM. intravascular system for measuring the pressure gradient across a stenotic lesion. It comprises an elongated, flexible, plastic, extruded, tubular member having a guidewire port extending through the wall thereof a short distance proximal to the distal end of the tubular member to intersect with a lumen which extends to the distal end. The second lumen runs the entire length of the tubular member from its distal end to its proximal end. The proximal end of the blood pressure monitor catheter is fitted to a molded plastic hub to facilitate the attachment of the catheter to the blood pressure measuring apparatus with which the catheter is to be used.

摘要： A handle device for an endoscope incorporates controls for adjusting the degree of curvature of the distal tip portion of the endoscope as well as the degree of extension of the surgical instrument beyond the distal end of the endoscope's working lumen. The handle member comprises a generally hollow body which is dimensioned to be readily grasped by the surgeon and it incorporates a thumb-slide having a ratchet surface thereon, the thumb-slide being joined to a pull-wire extending the length of the endoscope and fastened at its distal end to the body of the endoscope. By depressing and longitudinally sliding the thumb-slide, the curvature of the distal end of the steerable endoscope is controlled. The degree of extension of the working instrument beyond the distal end of the working lumen is controlled by a rotatable threaded rod which is designed to produce only translational motion to the instrument without any twisting thereof. The handle member also includes provisions for introducing a flushing liquid into the endoscope's working lumen but without flooding the interior of the handle.

摘要： The guide catheter system for use in the treatment of coronary artery disease includes a first single-lumen catheter of a relatively large internal diameter to pass a second guide catheter therethrough. The first guide catheter comprises an elongated flexible tube having a stainless steel braid embedded in the wall thereof for imparting desired torqueability characteristics to it. The first guide catheter is intended to be inserted at an appropriate point in the vascular system and then advanced until its distal end reaches the coronary ostium. The second guide catheter is fabricated by extruding a plastic, such as polyurethane thermoplastic resin over a tubular Teflon.RTM. core and because it is to be used within the lumen of the first catheter, it need not include a braided structure within its walls to prevent it from kinking. This allows the second catheter to be sufficiently slim to permit it to be advanced into a coronary artery while allowing fluids to be perfused between the outer wall of the second guide and the inner wall of the first guide catheter while still providing a sufficiently large inner lumen to pass a working catheter, e.g., an angioplasty or atherectomy catheter. An atraumatic tip is attached to the distal end of the second guide catheter.
摘要翻译：用于治疗冠状动脉疾病的引导导管系统包括具有较大内径的第一单腔导管以使第二引导导管穿过其中。第一引导导管包括细长的柔性管，其具有嵌入其壁中的不锈钢编织物，以向其施加期望的扭矩特性。第一引导导管旨在插入血管系统中的适当位置，然后前进直至其远端到达冠状口。第二引导导管通过在管状特氟隆TM芯上挤出诸如聚氨酯热塑性树脂之类的塑料制成，并且由于其将被用于第一导管的内腔内，所以不需要在其壁内包括编织结构以防止从扭结。这允许第二导管足够纤薄以允许其进入冠状动脉，同时允许流体在第二引导件的外壁和第一引导导管的内壁之间灌注，同时仍然提供足够大的内腔通过工作导管，例如血管成形术或粥样斑块切除术导管。无创伤的尖端附接到第二引导导管的远端。

摘要： A catheter assembly especially designed for the performance of atherectomy procedures which include an elongated flexible plastic tube which can be routed through the vascular system to the location of the atheroma to be removed and a working catheter insertable through the guide catheter in the form of an elongated flexible plastic tube having a series of fibers integrally formed with or otherwise attached to the distal end portion of the working catheter and normally laying flat against the wall of the catheter. The proximal end of the working catheter is adapted for connection to a high speed motor whereby the working catheter can be rotated relative to the surrounding guide catheter. As the distal end portion of the working catheter is advanced distally beyond the end of the guide catheter, centrifugal force acts upon the fibers to cause them to extend radially outward from the core of the working catheter and when advanced against an atheroma, flail the lesion, reducing it small particles which can be aspirated out the proximal end of the catheter assembly.

摘要： An intravascular catheter designed to apply a liquid medicament or other substance to a stenotic lesion as the blood vessel is undergoing dilatation to facilitate the restoration and long-term maintenance of patency to the blood vessel. It comprises three concentrically arranged flexible plastic tubes and a pair of concentrically arranged expander members located at the distal end of the tubes. The space between the outer wall of the inner tube and the inner wall of the intermediate tube is in fluid communication with the interior of the first expander member while the space between the outer wall of the intermediate tube and the inner wall of the outer tube is in fluid communication with the interior of the second expander member. A plurality of minute holes are formed through the second expander member such that when the liquid medicament is introduced into the lumen of the outer tube while an inflation fluid is introduced into the lumen of the intermediate tube, both expander members inflate with the drug or other substance being ejected out through the tiny pores of the outermost expander member while continued inflation of the inner expander member provides the necessary pressure for dilatation of the lesion.
