  • Patent number: 5397312
    Abstract: An applicator for introducing a cream-type substance into a woman's vagina is provided with an elongated holder having at its front end a space for accommodating the substance and a passage opening. A rod-shaped piston shuts off the space at the side facing away from the passage opening and can be operated for pressing the substance through the passage opening out of the space. The holder is transparent and is externally slightly curved in order to facilitate its use. The holder is provided on the outside with a projecting stop plate which limits the part of the holder to be inserted into the vagina. At the side of the stop plate facing away from the passage opening the holder is further provided with a handle which is long enough to be gripped with the whole hand. The holder is also provided on the outside, viewed relative to the radius of curvature, with supporting means for supporting the applicator with the passage opening facing upwards.

  • Patent number: 5385540
    Abstract: A cardioplegia system for delivering cardioplegic solution to the heart during open heart surgery in cooperation with an extracorporeal blood circuit employing a heart/lung machine, includes a conduit diverting a portion of the blood flow from the heart/lung machine to a cardioplegia delivery line. A heat exchanger for controlling fluid temperature is provided in the cardioplegia delivery line. A first pump combines the blood from the conduit with a second fluid and delivers the combined flow into the delivery line leading to the heat exchanger. A control panel is operatively connected for adjusting the ratio of blood and second fluid delivered by the first pump and for adjusting the total volumetric rate of flow from the first pump.

  • Patent number: 5383849
    Abstract: A method and device for selective endoscopic cannulation is disclosed. The cannulator includes an elongated intermediate portion which is normally straight and flexible and a distal tip portion which flexibly deviates in a specific direction away therefrom. The cannulator also includes a referential coupling, maintained in fixed relation within the cannulator, which allows bending of the cannulator along a portion of the length of the cannulator in a first plane which is transverse to the longitudinal axis of the referential coupling while resisting bending in other transverse planes relative thereto. The cannulator is advanceable through the operating channel of an endoscope and through the entrance into the ductal system, where it can be positioned with the referential coupling located at the entrance to the ductal system.

  • Patent number: 5383852
    Abstract: A steerable electrocardial catheter comprises an elongated flexible shaft and a flexible tip assembly connected to the distal end of the shaft. The tip assembly comprises a distal section and a proximal section coaxial with the shaft, the stiffness and length of the distal and proximal sections being selected to provide a predetermined curve configuration of the tip assembly when the distal section and/or proximal section is bent. A first pair of pull cables extending through the catheter is anchored at a first point in the tip assembly for bending the proximal section in a predetermined plane. A second pair of pull cables extending through the catheter is anchored at a second point in the tip assembly for bending the distal section in a predetermined plane. Any desired orientation of the bending planes is possible with the invention. A handle/actuator is also disclosed for applying tension to selected ones of the pull cables for controlling the deflection of the tip assembly.

  • Patent number: 5378237
    Abstract: The present invention relates to a dilatation catheter designed to be introduced into a canal of the body. The invention finds a particular application in the treatment of diseases of the coronary arteries. According to the invention, the balloon has an outer wall designed to come into contact with the inner wall of the body canal, while in the position of use, and an inner wall fixed in a tight manner to the outer wall to define therewith, while in the position of use, an inner annular cavity. The catheter further includes a support element shaped so as to hold the inner wall of the balloon, in the position of use, while allowing the body fluid to flow in the space between an inner element and the inner wall of the balloon.

  • Patent number: 5372583
    Abstract: A bone marrow infuser has an intraosseous cannula, a hand driver, and a pointed stylet attached to the hand driver. The hand driver can mechanically couple with the intraosseous cannula so that the stylet point protrudes from an opening at the end of the intraosseous cannula. A method of bone marrow infusion has a first step of puncturing the skin with the point of the stylet, a second step of embedding the cannula into the bone, a third step of removing the stylet from the cannula and attaching the catheter to the cannula, a fourth step of applying pressure to compress the skin, flesh, and bone, and a final step of infusing fluids into the bone marrow.

  • Patent number: 5370609
    Abstract: A method of and apparatus for removing a thrombus deposit from the cardiovascular system of a patient without the need to surgically access the location of the thrombus deposit via a cut-down or other surgical procedure. A catheter is inserted percutaneously into the patient at a convenient location either directly or over a previously positioned guide wire. The distal end of the catheter is advanced under fluoroscopy to the site of the thrombus deposit. A balloon is inflated to stabilize the position of the distal end of the catheter within the center of the vessel lumen. A flexible metal tube conveys an extremely high pressure stream of sterile saline solution to at least one jet at the distal end of the catheter. At least one jet positions the thrombus deposit for emulsification by at least one other jet. By directing the jets toward the orifice of the large evacuation lumen of the catheter, a stagnation pressure is induced which propels the emulsion proximally for disposal.

  • Patent number: 5370614
    Abstract: A balloon catheter includes a sheath surrounding the balloon, the sheath having a longitudinal line of weakness and a drug-containing viscous matrix material intermediate between the balloon and the sheath such that when the balloon is positioned and inflated in the body lumen it causes the sheath to burst at the line of weakness and release viscous matrix material onto said body lumen. The device provides accurate placement of the dosage required at the location in need of treatment. The catheter is especially useful in balloon angioplasty procedures.
