摘要： Vascular access systems for performing hemodialysis are disclosed. The vascular access system contemplates a catheter section adapted for insertion into a vein and a graft section adapted for attachment to an artery. The catheter section may have metal or polymer wall reinforcements that allow the use of thin-walled, small outer diameter conduits for the vascular access system. One or more of the adhered, embedded or bonded conduit reinforcement structures may be removable without significant damage to the conduit sections to facilitate attachment of the sections, or to a connector between the sections. Various self-sealing materials are provided for use in the vascular access system, as well as temporary access sites and flow control/sensor systems.

摘要： Vascular access systems for performing hemodialysis are disclosed. Some embodiments relate to vascular access grafts comprising an instant access or self-sealing material reinforced with expanded PTFE to resist stretching of the instant access material and thereby resist leakage associated with stretching or bending. The graft may comprise two end segments comprising ePTFE without the instant access material to allow easier anastomosis of the graft to veins and arteries. The graft may have a unibody design or have modular components that may be joined together to create a graft with customized length or other features. One or more sections of the graft may also be cut or trimmed to a custom length.

摘要： This invention provides a light delivery catheter having a proximal shaft with two lumens and a distal shaft connected to the proximal shaft, which distal shaft has only a single lumen. A guidewire and a light guide are received in the first and second lumens resectively, of the proximal shaft, either of which may be extended into the single lumen of the distal shaft, the distal shaft being sufficiently flexible to facilitate movement of the catheter through tortuous paths. A hub is provided having ports through which appropriate fluids may be applied to the lumens. When used to remove a blood clot in a blood vessel of the brain or other part of the body, the guidewire is extended through the single lumen in the distal shaft and is utilized to guide the catheter adjacent the clot, at least one guidewire/light guide exchange being performed to ablate the clot. Alternatively, the catheter may initially be passed through the clot to the distal side thereof and the catheter retracted through the clot as light energy and contrast fluid are applied therethrough.

摘要： An optical switch is disclosed including a first and second array of optical fibers held in axial alignment and relatively rotatable about an axis of rotation to effect optical coupling and decoupling of fibers of the opposing arrays. Terminal ends of fibers of the first array are set at a predetermined non-orthogonal angle relative to the axis of rotation. Terminal ends of fibers of the second array are set at an angle which is complementary to the non-orthogonal angle.

摘要： There is disclosed a manipulation and storage tool for receiving and manipulating a partially dehydrated intervertebral disk. Manipulation and storage tool is configured to receive the disk and manipulate it into a smaller overall size and subsequently insert it into a temporary storage or sleeve device for later use. Manipulation and storage tool generally includes a manipulation assembly which is movably mounted with respect to a guide assembly. The guide assembly includes a throughbore and a slot for receiving the disk into the throughbore as well as a sleeve holder mounted at a distal end designed to retain a storage device or sleeve into which the manipulated disk is inserted. The manipulation assembly generally includes a drive member having an elongated shaft movably mounted within the bore of the guide assembly and at least one manipulation member for pin positioned adjacent the slot to manipulate the implant in response to movement of the drive member relative to the guide assembly. Preferably, the drive member and guide assembly are inter-connected by a drive rod having a chive pin which guides the motion of drive member with respect to the guide assembly in response to rotation of the drive member to manipulate the disk and insert it into the sleeve. There is also disclosed an insertion tool for receiving an assembled sleeve and disk and inserting the manipulated disk into an intervertebral disk space. Methods of use of the manipulation and storage tool and the inserter tool are also disclosed. There is also disclosed an implant folding and storage device including an implant folding device having a pair of jaws configured to fold an implant therebetween. An implant transfer device is provided to move the folded implant from within the implant folding device and into an implantation tube. There is also disclosed a novel surgical instrument assembly for receipt of a folded implant and installation of the implant into a portion of the body.

摘要： Non-occluding catheters and methods for delivering energy to a vessel wall without occluding blood flow through the vessel wall are disclosed. In particular, the invention uses an energy distributor connected to an expansion mechanism and a waveguide. The expansion mechanism causes the distributor to come into close proximity with a target region in the vessel wall, while maintaining at least one fluid passageway for blood flow throughout the instrument.
