  • Publication number: 20140276615
    Abstract: The invention is a delivery catheter, e.g., a guide catheter, having an imaging element in proximity to the distal end of the catheter. Catheters of the invention are able to placement of the catheter in proximity to an ostium, thereby increasing the efficiency of contrast delivery while reducing the risk of ischemia due to blocked blood supply. The invention additionally assists in maintaining catheter position during delivery of a fluid from the catheter, resulting in better performance with less fluid. For example, a catheter of the invention can be used to produce improved fluoroscopic images with less overall contrast. This improvement reduces the risk of an allergic reaction to the contrast while decreasing the length of time for a procedure, i.e., because of a need to re-contrast.

  • Publication number: 20120041392
    Abstract: A specialized cannula and intraluminal cannula placement apparatus allow the insertion of an intraluminal cannula through a previously inserted standard I.V. catheter so that the intraluminal cannula extends beyond the end of a standard catheter. By using an intraluminal cannula of appropriate length, the intraluminal cannula may be used to bypass a flexure-caused obstruction in a vein during the administration of fluids in patients who are unable to cooperate with medical or veterinary procedures, most particularly with human infants, geriatric patients, and animals. Use of the specialized cannula and intraluminal cannula placement apparatus does not require removal of the previously placed I.V. catheter. The exterior diameter of the specialized cannula has a smaller diameter than the interior diameter of the previously placed standard I.V. catheter. A specially adapted seal seals the space between the inserted specialized cannula and a standard Luer hub of an I.V. catheter.

  • Patent number: 7888304
    Abstract: The present disclosure is directed to methods and compositions for clearing and cleaning enteral feeding tubes. More particularly, the composition is an ingestible gel composition that comprises enzymes for degrading buildup in enteral feeding tubes, carrageenan, and divalent metal ions or a source thereof. The carrageenan present in the composition stabilizes the enzymes at room temperatures, allowing for long-term storage of the composition. Upon injecting the gelled composition into the feeding tube, body heat from the patient melts the gel, and the enzymes are released to act on debris present in the feeding tube.

  • Patent number: 7854728
    Abstract: In accordance with embodiments of the present invention, a debris removal system is provided for a body-space drainage system having one or more body tubes with a body tube lumen disposed therein. The debris-removal system comprises a cleaning member, a collapsible sheath, and a coupler. The cleaning member is an elongated member wherein the distal end is adapted to enter the body tube lumen at or near the body-tube proximal end and adapted to be advanced distally at least a portion of a length of the body tube lumen. The collapsible sheath is adapted to contain at least a portion of the cleaning member that is not contained within the body tube lumen. The collapsible sheath is flexible so as to allow external digital manipulation of the cleaning member proximal end within of the collapsible sheath, while retaining the sterile environment of the body-space drainage system.

  • Publication number: 20100125253
    Abstract: A dual-tip catheter equipped with both a rotating cutting bit and a cavity for a probing guidewire tip for passage through chronic total occlusions or other refractory atherosclerotic plaque from diseased arteries. The catheter's guidewire tip and rotating cutting bit reside safely within an outer protective catheter sheath head when not in use, and alternately either the cutting bit or the guidewire tip will protrude out of the same distal opening of the sheath head as needed. By first drilling through refractory occlusions, and then inserting a guidewire tip into the occlusion opening formed by the cutting bit, the catheter can force the guidewire tip past the occlusion. After the guidewire tip has been fully inserted, the dual-tip catheter can be withdrawn, and an alternate catheter inserted and directed up the guidewire to the occlusion site, where the alternate catheter can perform further occlusion enlargement or therapeutic activity.
