  • Patent number: 6605076
    Abstract: A pre-slit injection site includes a housing with a flow path therethrough. A first end of the housing carries a pre-slit septum. One form of a blunt cannula, usable with the injection site, carries a locking member. When the pre-slit injection site slidably receives the blunt cannula, the locking member latches to the injection site and creates a mechanically coupled unit. Another form of the cannula includes a tube having a tapered distal end region and having elongate discharge slots for reducing contact surface area and for directing the flow laterally out of the cannula. The cannula may also include a rounded lead post, an annular barb, and axially oriented grooves.

  • Patent number: 6413262
    Abstract: A method of crystalline lens replacement for eyes comprises the steps of forming a small hole that penetrates through the lens capsule, removing a part of the crystalline lens substance through the hole, refilling the lens capsule by injecting a composition comprising a hydrophilic polymer directly into the lens capsule, and closing the hole. The method of crystalline lens replacement may be performed on animals or humans. Furthermore, the method of crystalline lens replacement may be performed on a patient suffering from cataract, where the opaque crystalline lens substance in the lens capsule is removed.

  • Patent number: 6406484
    Abstract: A system and method for removing impacted cerumen from within a person's auditory canal. The system includes a hand held instrument that is held against the ear, and a base that creates a negative pressure in the hand held instrument when it is not in use. The hand held instrument contains an auditory canal plug that seals over the auditory canal when manually biased against the auditory canal. The plug contains an aperture that leads to a vacuum chamber within the hand held instrument. The flow of air through the auditory canal plug and into the vacuum chamber is controlled by a manually operated flow control valve. The hand held instrument merely carries the vacuum chamber. To create a negative pressure in the vacuum chamber, the hand held instrument must be placed on a base. The base contains a vacuum pump that pneumatically interconnects with the vacuum chamber when the hand held instrument is placed on the base.

  • Patent number: 6395019
    Abstract: An endovascular graft which is configured to conform to the morphology of the vessel to be treated and which is made from an inflatable structure having a proximal end with a proximal inflatable cuff and a distal end with a distal inflatable cuff. At least one elongated inflatable channel is disposed between and in fluid communication with fluid tight chambers of the inflatable cuffs which may contain rupture discs therebetween which can be configured to rupture at different pressures. A thin flexible barrier disposed between the inflatable cuffs and the elongated inflatable channel of the frame so as to form a tubular structure defining a longitudinal channel to confine a flow of blood or other fluid therethrough. The graft may also have an expansion member attached to the proximal end of the graft which is preferably made of linked expandable rings of pseudoelastic shape memory alloy which is self expanding and prevents axial displacement of the graft once it is deployed.

  • Patent number: 6391045
    Abstract: A vascular filter comprises an emboli-capturing portion having a set of helical filter-wires joined at a central region and extending in a given direction along the blood vessel in a diverging relationship to the axis of the filter, the wires terminating in free ends constructed to engage the walls of said vessel. A major mid-portion of the length of the free ended wires are of generally helical form, cooperatively related to form an effective emboli capturing array. Anchoring is accomplished by a separate assembly formed of struts and anchoring devices. A parallelogram supporting strut assembly and other means for providing linear engagement with the wall of the vena cava are shown. The parallelogram structure is shown to have filter capability by itself as well.

  • Patent number: 6391046
    Abstract: Hand-held instruments which may be employed to actuate a distally mounted tool by application of radial compressive force about the instrument circumference (i.e., omni-actuatable). In preferred forms, hand-held instruments have a handle which includes an actuator assembly for actuating a tool, wherein the actuator assembly has a generally V-shaped circumferential channel in which an actuator band is seated. A slide ring assembly is provided which defines the generally V-shaped circumferential channel and has at least one slide ring mounted for longitudinal movements relative to the handle. The actuator band is radially flexible. Thus, in response to a compressive force, the actuator band seated within the generally V-shaped channel will be flexed radially inwardly to thereby moves the slide ring longitudinally. The slide ring, in turn, coacts operatively with the distally mounted tool (e.g., through a longitudinally slidable actuator pin).

  • Patent number: 6319267
    Abstract: The endoluminal device delivery assembly and method for release and deployment of an endoluminal therapeutic device at a desired location for treatment within the vasculature of a patient utilizes an elongated flexible tubular catheter with a tubular distal tip formed of a yieldable material mounted to the distal end of the catheter for releasably holding the proximal end of the endoluminal device. The endoluminal device can be dislodged from the tubular distal tip by a pusher member or pressurized fluid to expel the endoluminal device through at the desired location for treatment within the vasculature of a patient. A flexible coil can be mounted to the distal end of the elongated pusher member to provide for improved tracking.

  • Patent number: 6283983
    Abstract: Methods and devices for percutaneous, in situ coronary bypass wherein a tissue puncturing catheter is used to form blood flow paths between an artery and an adjacent vein such that arterial blood will flow through a segment of the adjacent vein, thereby bypassing a lesion in the artery. The tissue puncturing catheter comprises a flexible catheter having a tissue puncturing apparatus such as a sharp tipped member, an electro-surgical apparatus or a laser beam passable therefrom to create the desired blood flow paths between the artery and vein. Stents are provided for facilitating blood flow through the blood flow paths and the segment of the vein used as the bypass conduit. One such stent is specially constructed to carry arterial blood in one direction through the vein segment while allowing venous blood to continue to flow in the opposite direction through that venous segment.

  • Patent number: 6245040
    Abstract: A dilation catheter suitable for use in medical procedures is provided which includes a balloon disposed on an elongated flexible tube. The tube is capable of passing fluid between the balloon and the tube for varying the balloon between a collapsed and expanded condition. The catheter includes a brace fitted over the balloon for restricting expansion of a selected portion of the balloon for forming a perfusion channel that allows fluid to be perfused past the balloon when it is expanded in a body vessel. A medical procedure for dilation under perfusion conditions is also provided.
