Endoluminal Graft System And Method Of Implanting The Same, David J. Minion
Endoluminal Graft System And Method Of Implanting The Same, David J. Minion
Surgery Faculty Patents
An endoluminal graft system comprising an endoluminal graft including a framework and a flexible fabric surrounding the framework, a deflection means configured for placement through an opening to a branching vessel, and a delivery catheter configured to position the endoluminal graft within a primary vessel. A method of implanting the endoluminal graft includes positioning the endoluminal graft within a primary vessel with a leading edge of the endoluminal graft adjacent to an opening to a branching vessel. A deflecting means is positioned through the opening to the branching vessel adjacent to the leading edge of the endoluminal graft. The endoluminal …
Method Of Predicting Obesity Comprising Measuring Neurotensin, B. Mark Evers, Jing Li, Paul Dobner, Olle Melander
Method Of Predicting Obesity Comprising Measuring Neurotensin, B. Mark Evers, Jing Li, Paul Dobner, Olle Melander
Surgery Faculty Patents
The presently disclosed subject matter relates to a method for predicting increased risk of obesity on a non-obese subject. More particularly, the presently disclosed subject matter relates to a method of predicting increased risk of obesity in a non-obese subject by determining a level of neurotensin expression in a biological sample from the subject and comparing the level of neurotensin expression in the sample with a control level. The presently disclosed subject matter further relates to a method of preventing and/or treating obesity in a subject in need thereof by administering to the subject an effective amount of an agent …
Graft Within A Graft Endoluminal Graft, David J. Minion
Graft Within A Graft Endoluminal Graft, David J. Minion
Surgery Faculty Patents
A segmented endograft includes at least one positioning segment and at least one main body segment which are separately deployable. The at least one positioning segment and at least one main body segment may be connected one to another. For example, the at least one positioning segment and at least one main body segment may be connected along a portion of a circumference thereof, but unconnected along a remainder of the circumference thereof. The at least one positioning segment overlaps a portion of the at least one main body segment. Deployment systems may include the segmented endograft and the segmented …
Compact Heat Exchanger For Veno-Venous Perfusion-Induced Systemic Hyperthermia Systems, Dongfang Wang, Joseph B. Zwischenberger
Compact Heat Exchanger For Veno-Venous Perfusion-Induced Systemic Hyperthermia Systems, Dongfang Wang, Joseph B. Zwischenberger
Surgery Faculty Patents
A compact heat exchanger for vena-venous perfusion-induced hyperthermia includes an integral pneumatic pump and a hollow tubule heat exchange array. A vena-venous perfusion-induced hyperthermia system incorporating the compact heat exchanger is described. The heat exchanger provides a compact, efficient design allowing a lesser heat exchanging surface area and lesser required pumping power compared to conventional systems. In turn, the system provides a shorter blood circuit compared to conventional systems, allowing maintaining a lower blood temperature than such conventional systems while supplying sufficiently heated blood to patient visceral organs to provide a therapeutic effect, such as in supplementing chemotherapy drugs.
Even Perfusion Pump-Integrated Blood Oxygenator, Dongfang Wang, Joseph B. Zwischenberger
Even Perfusion Pump-Integrated Blood Oxygenator, Dongfang Wang, Joseph B. Zwischenberger
Surgery Faculty Patents
A blood oxygenator includes an integral pneumatic pump disposed substantially within a housing thereof, an inlet blood flow redirector, and an outflow blood collector. An atrium provided at an inlet of the oxygenator promotes even delivery of blood to the oxygenator. In use, the oxygenator provides an even dispersion of blood therethrough, establishing even perfusion and reducing areas of stagnant blood flow.
Axial-Centrifugal Flow Catheter Pump For Cavopulmonary Assistance, Dongfang Wang, Joseph B. Zwischenberger
Axial-Centrifugal Flow Catheter Pump For Cavopulmonary Assistance, Dongfang Wang, Joseph B. Zwischenberger
Surgery Faculty Patents
An axial-centrifugal flow catheter pump for cavopulmonary assistance is provided, incorporating a rotor providing both an axial fluid flow and a centrifugal fluid flow. The rotor includes a first terminal impeller configured to provide a centrifugal and axial fluid flow in a first direction, a second terminal impeller configured to provide a centrifugal and axial fluid flow in a second direction opposite to the first direction, and a central impeller configured to provide a predominantly centrifugal fluid flow. The first and second terminal impellers each include blade arrangements configured to provide a centrifugal and axial fluid flow directed toward the …
Laser Skin Graft Harvesting Apparatus And Related Method, David S. Kirn
Laser Skin Graft Harvesting Apparatus And Related Method, David S. Kirn
Surgery Faculty Patents
A laser dermatome is disclosed for harvesting and meshing grafts of skin. A roller driven by a motor lifts the leading edge of a portion of skin for cutting by a beam of light generated by a laser. Adhesive tape attached to the roller aids in lifting the portion of skin and is further utilized to secure the severed portion of skin to the roller. A stage mounted atop an axle supports the laser or a beam director. The movement of the stage is controlled by second and third motors which drive the stage along or rotate it about the …
Portocaval-Right Atrial Shunt, Bradley B. Hill
Portocaval-Right Atrial Shunt, Bradley B. Hill
Surgery Faculty Patents
A shunt includes a tubular body having first and second legs at a proximal end and a third leg at a distal end. A fluid distensible balloon and cooperating insufflation conduit are carried on the tubular body. The first leg of the tubular body includes a longitudinal slit for receiving the second leg whereby the first and second legs may be positioned substantially coaxial so as to allow easier introduction of the shunt into the blood vessel of a patient. Similarly, the second leg having a longitudinally slit for receiving a portion of the cooperating insufflation conduit and also holding …
Angled Snare Assembly, Bradley B. Hill
Angled Snare Assembly, Bradley B. Hill
Surgery Faculty Patents
A snare assembly includes an outer, flexible sheath having a distal opening and a loop received for relative sliding movement with respect to the sheath. The loop has a proximal end and a distal end. The loop is formed from a resilient wire and includes a substantially 180° reverse bend at a midpoint forming the distal end and the ends of the wire are fastened together at the proximal end. A control handle is carried on the sheath for extending and retracting the loop out of and into the sheath through the distal opening. A flexible connector connects the control …

Method For Employing The Delta Opioid Dadle To Extend Tissue Survival Time During Ischemia, Sufan Chien
Surgery Faculty Patents
This invention concerns a method for extending the survival time of mammalian lung tissue subjected to ischemia, by which said tissue is perfused with a preservation solution comprising a therapeutic dose of the delta opioid DADLE ([D-Ala2,D-Leu5]-Enkephalin) under hypothermic conditions.
Method Of Tendon Repair, Bradley B. Hill
Method Of Tendon Repair, Bradley B. Hill
Surgery Faculty Patents
A method for repairing a transected or torn flexor or extensor tendon of a finger that has retracted proximally within its protective sheath includes the steps of: (a) visually locating a distal end of the tendon within the sheath; (b) engaging the distal end of the tendon, (c) pulling the tendon distally through the sheath to a tendon mending position; and (d) repairing the tendon.

An apparatus and its method of use are provided allowing lavage, sump and enteral feeding operations with only one intubation. The apparatus includes a first tube having two distinct passageways. One of these passageways completely contains a second, feeding tube during intubation. Once the first tube is in place in the patient, the second tube is extended from the first tube so as to enter the stomach. The extension of the second tube opens ports in the first passageway of the first tube, thereby allowing sump or lavage treatment with the second passageway of the first tube serving as an …
