  • Patent number: 7854758
    Abstract: A system and method for exclusion of an aneurysm of an aortic arch region using a graft delivery system capable of maneuvering around an aortic arch, an aortic arch graft, and an occluder system for isolating an aneurysm while occluding one or more corresponding arteries, and with bypass of those arteries being performed using one or more selected bypass grafts. The graft may be branched or branchless. The graft delivery system has a flexible sheath that is manipulated manually with the aid of a guidance system. A hoist delivery system may also be provided. The occluder system may comprise independent occluders with one or more anchor members adjacent to one end. Alternatively, the occluders can be provided as part of the aortic arch graft, either as a built-in singular self-deploying occluder or as built-in multiple occluders. A kit is also provided containing a graft, stents, occluders, and optional delivery system.

  • Publication number: 20100234938
    Abstract: An apparatus for use within a vasculature includes a primary guider having a proximal end, a distal end and a medial portion extending from the proximal end to the distal end. The proximal end includes a proximal opening. The distal end includes a distal opening. The medial portion includes a lumen interconnecting the proximal opening and the distal opening. A grasper is provided at the distal end. A grasper controller is provided for controlling the grasper. The apparatus has various uses, including as a device to deploy a second intraluminal device for attachment to a first intraluminal device within a vasculature. The grasper may be used to grasp the first intraluminal device in order to facilitate attachment of the second intraluminal device. The apparatus may also be used for filtering, with the grasper being constructed to trap blood-borne material while permitting bloodflow.

  • Publication number: 20070009584
    Abstract: A wound treatment apparatus may include an impermeable or semi-permeable dressing, a securement strap on the dressing for securing the dressing over a wound on a patient, and a pressure/vacuum generator in fluid communication with the dressing. A wound treatment method utilizing the wound treatment apparatus may include placing the dressing of the apparatus over a wound, securing the securement strap of the apparatus around a body portion of a patient where the wound is situated, and manually operating the pressure/vacuum generator to selectively deliver positive or negative air pressure to the dressing and the wound. In another aspect directed to leg wound care, a wound treatment apparatus may include an impermeable or semi-permeable dressing and a vacuum generating foot pump in fluid communication with the dressing. The foot pump is manually operable by a patient and adapted to deliver air pressure (negative or positive) to the dressing and the wound.

  • Publication number: 20060282158
    Abstract: A temporary absorbable venous occlusive stent for use in a varicose vein treatment method includes a stent body, a bio-absorbable material associated with the body, and a closure for blocking blood flow past the stent when implanted in a vein. The stent produces localized blood clotting, fibrosis and vein collapse as it is absorbed. A permanent blockage is produced that prevents the undesirable back flow of blood from above the blockage site, thereby reducing distension of a varicose vein below the blockage site.

  • Publication number: 20060235077
    Abstract: A diverticular remodeling technique comprises the introduction of a remodeling agent into the diverticulum to promote permanent closure of the diverticular sac. In disclosed exemplary embodiments, the diverticulum is accessed non-invasively and optionally cleaned to remove unwanted matter therefrom. The remodeling agent is introduced into the diverticular interior and the neck of diverticulum is closed (as necessary) to prevent egress of the remodeling agent. The remodeling agent can be any of a variety of materials, including small intestine submucosa (SIS) collagen or other absorbable fibrosis materials in gel, liquid or solid form. An endoscopic device may be used that includes a multi-lumen flexible catheter having a distal end adapted to be steered through a patient and a proximal end that remains outside the patient's body.

  • Publication number: 20060070178
    Abstract: A disposable shower system for non-ambulatory patients includes a flexible waterproof bag enclosure, a patient access opening in the bag enclosure to enable a patient to be placed therein, and an adjustable closure for adjustably closing the access opening to selectively create a wholly or partially watertight bathing environment within the bag enclosure. A fresh water delivery system delivers water from a fresh water source into the bag enclosure, where it can be dispensed onto a patient. A waste water removal system removes and collects waste water from the bag enclosure. During use of the shower system, the patient is placed in the bag enclosure with the patient's head protruding from the patient access opening, and the closure is manipulated to close the access opening as desired. Using one or more dispensing nozzles associated with the fresh water delivery system, the patient is bathed with fresh water while waste water is collected and removed by the waste water removal system.

  • Publication number: 20040193284
    Abstract: A cardiomyoplasty method for treating cardiomyopathy using a myometrial compostion of myometrial tissue, and a device for implantation without injection into the myocardium. The myometrial composition may include cut, granulated, ground or cultured myometrial tissue. The myometrial composition may also be treated with one or more additives such as cDNA vascular endothelial growth factor (VEGF), a patient's blood, or an adhesive. A first implantation device includes a tubular double lumen body having a first and second pathway, a spray opening adapted to deliver the myometrial composition, and a pressure valve to release unsafe pressure within the pericardium. A second implantation device includes a tubular lumen outer body and a first and second tubular lumen inner bodies. The first inner body has an expandable portion to carry a myometrial tissue patch. The expandable portion may include longitudinal slots to carry the myometrial composition.

  • Patent number: 6690970
    Abstract: A biological pacemaker and implantation catheter for restoring normal or near normal heartbeat function without a mechanical pacemaker. The biological pacemaker is provided by a bridge of implantation cells, such as nerve cells, stem cells or ganglion cells, that are introduced into an area of electrical malfunction, such as an impaired SA node or a blocked AV node. The implantation cells grow to form a conductive cell bridge around the malfunction area so that a new pathway is provided for the electrical signals responsible for triggering heart beat contractions. The implantation catheter has a central nerve cell injection needle connected to a syringe or the like via a cell injection tube, and two elongated lateral stabilizing needles. The catheter is inserted into a blood vessel in a patient's leg, arm, shoulder or the like, and advanced until the catheter's distal end is located above the malfunction area.
