Patent number: 5833657Abstract: A balloon element for use in a catheter has a multi-layered single-walled structure and a compliance characteristic exhibiting a first, non-compliant region at low operating pressures and a secondary compliant region at higher operating pressures. The properties of the balloon element permit it to serve for both dilatation of bodily vessels and stent delivery and implantation. A method of manufacturing the balloon element involves extrusion of a tube of material, such as PEEK, which serves as an inner wall layer of the finished balloon element and provides the desired strength and compliance characteristics of the balloon element, and a post-extrusion over the first tube, which provides an outer wall layer in the finished balloon element imparting abrasion resistance and other desirable mechanical properties.Type: GrantFiled: May 3, 1996Date of Patent: November 10, 1998Assignee: Ethicon, Inc.Inventors: Robert W. Reinhardt, Nicholas A. Green

Patent number: 5782906Abstract: A stent which may be emplaced into the lumen of the body. The stent has an expandable first section with a first diameter and an expanded second diameter larger than its first diameter. There is also a second section connected to the first section, the second section contains a third diameter and an expanded fourth diameter which is larger than the third diameter. Finally, the second diameter is different from the fourth diameter. Thus, the device may be emplaced between lumens of different sizes. Ideally, this stent can be placed at the junction at the aorta and the iliac arteries, where the size of the lumens are typically different. In use, therefore, the device provides the surgeon with a useful tool to holding open junctions of various sized lumens.Type: GrantFiled: October 24, 1996Date of Patent: July 21, 1998Assignee: Ethicon, Inc.Inventors: Paul Marshall, Anthony S.

Patent number: 5759172Abstract: The invention relates to a catheter comprising a tube-like basic body with a proximal and a distal end and an expandable balloon member arranged close to the distal end to the basic body. The balloon member comprises a number of relatively stiff sections extending on a small diameter in a longitudinal direction of the basic body and relatively pliable sections extending inbetween, wherein the relatively pliable sections form lobes in an expanded state of the balloon member. The invention furthermore relates to a method for manufacturing a catheter according to the invention, wherein a piece of tube-like basic material is provided and, by blow molding, a balloon member is made in a mold, which is arranged to the bias material. The balloon member is manufactured in the mold cavity of a mold, the cross-section of which is lobated, by receiving a tube-like partial manufacture inside it and deforming it by blow molding into a shape corresponding to that of the shape of the mold cavity.Type: GrantFiled: April 9, 1996Date of Patent: June 2, 1998Assignee: Cordis CorporationInventors: Jan Weber, Johannes Gerardus Maria Van Muiden

Patent number: 5740717Abstract: In contrast to typical machines though, the present invention discloses a device which allows the plate to "float" within the mechanism, so that any inaccuracies in dimensional tolerances between plate and knife are absorbed in a damping of the plate or bed of the mechanism. In this situation, the depth of the cut of the score line can be very reliably controlled, which results in the repeatable manufacturing of a child resistant, yet senior effective package. There is used a spring pre-load for this plate, which is such that cutting takes place yet, as the tool closes, the plate and package come in "metal to metal" contact, assuring "near perfect" cuts of the blister package. Extremely high tolerances are maintained, assuring packages which pass all levels and types of QA testing.Type: GrantFiled: December 19, 1996Date of Patent: April 21, 1998Assignee: McNeil-PPC, Inc.Inventors: Harry Sowden, Kenneth E. Fuller

Patent number: 5732871Abstract: An improved surgical instrument is provided for applying surgical fasteners, such as staples, to human tissue which is particularly suited for applying one or more rows of fasteners across a tissue lumen. The surgical instrument can be used in thoracic and abdominal surgical procedures where access to the surgical site is restricted. The surgical instrument includes an articulated fastener applying assembly mounted on a rotatable and flexible support shaft assembly to provide more convenient access to restricted surgical sites. The fastener applying assembly has a compact construction including a fixed jaw which supports a fastener cartridge and a movable jaw which supports an anvil for clamping the tissue therebetween. The fastener applying assembly includes a pin placement mechanism which is actuated by the movable jaw to control the movement of a tissue retaining pin on the fixed jaw.Type: GrantFiled: May 4, 1995Date of Patent: March 31, 1998Assignee: Ethicon, Inc.Inventors: George A.

Patent number: 5724981Abstract: A method and apparatus are described for determining characteristics of peripheral arterial volume and compliance. A blood pressure cuff is inflated and deflated around a limb of the body and pressure measurements are taken. The volume of air removed from the cuff is determined in a quantifiable manner, such as by expelling air through an orifice of known characteristics or by means of a volume of known characteristics. The detected pressures and volume of air removed are used to compute oscillation volume, which in turn is used to display arterial capacity and compliance as a function of transmural pressure and time. Arterial capacity may be displayed in terms of arterial radius, arterial cross-sectional area, or arterial volume. Also, systolic and pulse pressures are determined using only these determined values.Type: GrantFiled: November 22, 1994Date of Patent: March 10, 1998Assignee: Johnson & Johnson Medical, Inc.Inventor: Howard P. Apple
