20150101616 | Securable Procedure Kit - A procedure kit that removably retains components to be used during a medical procedure, such as the insertion of a catheter into a patient, is disclosed. The procedure kit is securable to a surface or structure such that the kit is positioned as desired by the clinician, thus minimizing chances that the kit will fall to the ground or undesirably move. In one embodiment, the procedure kit comprises a body defining a plurality of pockets that are sized to removably receive therein components for use in the medical procedure, an openable flap that covers at least a portion of the pockets; and an adhesive portion included on a portion of the body to enable the procedure kit to be secured to a structure or surface proximate to the patient, such as the sterile drape covering the patient. | 04-16-2015 |

20130030446 | TIBIOTALAR ARTHRODESIS GUIDE - A Tibiotalar Arthrodesis Guide (TAG) used for fusion of the talus to the tibia is comprised of several basic components. The main component is a straight guide post upon which other components can slide. A curved arm is featured at the end of the straight guide post, featuring points at the ends which serve as indicators of the pins' exit sites based upon the lines of action of the parallel pins. The parallel guide cylinders are positioned on a movable arm which translates superiorly and inferiorly on the guide post of the handle, allowing a surgeon to adjust the device for varying ankle sizes. A “home-run” pin guide cylinder for a home-run guide pin is oriented superiorly and at an angle to the parallel guide cylinders. Using a similar concept as the parallel guide cylinders, the “home-run” guide is also attached to a movable arm that can translate inferiorly and superiorly along the main guide post. A medial guide cylinder for a medial guide pin passes through one of a plurality of holes in a vertical guide arm. The surgeon has the flexibility to utilize either the “home-run” or medial pins, depending on the needs of the patient and preference of the surgeon and, in either case, the “home-run” and medial pin pass between the two parallel pins. | 01-31-2013 |

20120184971 | EXCHANGEABLE SYSTEM FOR MINIMALLY INVASIVE BEATING HEART REPAIR OF HEART VALVE LEAFLETS - Improved methods and apparatuses for heart valve repair in a beating heart of a patient utilize an exchangeable heart valve repair system. Heart valve repair system can include a port adapted to be seated in the heart wall and an imaging catheter slidable within the port. The imaging catheter can be selectively locked relative to the port for insertion into the heart and unlocked once the port is seated to allow the imaging catheter to move distally towards target tissue. A deployment catheter slidably disposed in the imaging catheter and a repair cartridge slidably disposed in the deployment catheter can be used to capture the target tissue and deploy a repair device into the tissue after proper capture is confirmed. System elements can be selectively removed from and replaced within port to deploy additional repair devices while port maintains a seal while elements are and are not inserted. | 07-19-2012 |
20130035757 | MINIMALLY INVASIVE REPAIR OF HEART VALVE LEAFLETS - A method of repairing a heart valve provides intravascular access for repair of a heart valve through a ventricular trans-septal approach. An external guide catheter can be inserted through a vein of a patient into the right ventricle via the right atrium. An internal guide catheter can be inserted through the external guide and can provide access to the septum for a puncture tool to create an opening through the septum to the left ventricle. The internal guide can then be advanced into the left ventricle and used to guide a deployment catheter that deploys a repair device onto the heart valve. | 02-07-2013 |
20130150710 | SURGICAL NAVIGATION FOR REPAIR OF HEART VALVE LEAFLETS - To improve the overall navigation process for minimally invasive repair of heart valve leaflets, an augmented reality technique capable of providing a robust three-dimensional context for transesophogeal echocardiography data has been developed. In the context of various embodiment of the invention, augmented reality essentially refers to a system in which the primary environment is virtual but the environment is augmented by real elements. In this real-time environment, the surgeon can easily and intuitively identify the tool, surgical targets, and high risk areas, and view tool trajectories and orientations. | 06-13-2013 |

20090133581 | VORTEX AIR-OIL SEPARATOR SYSTEM - The present invention provides a vortex generator that may be used in systems for separating oil from air oil mixtures. The vortex generator comprises a rotating disk having a rim having a plurality of passages extending through it and a cavity formed by the rotating disk and a cavity wall wherein a vortex is created when there is a flow through the plurality of passages into the cavity. | 05-28-2009 |
20090133961 | FREE VORTEX AIR-OIL SEPARATOR - The present invention provides a free vortex air-oil separator that may be used in systems for separating oil from air oil mixtures. The free vortex air-oil separator comprises a free vortex chamber having a first chamber wall, a second chamber wall located axially aft from the first chamber wall and a rim located in a radially outer region from an axis of rotation, a plurality of vent holes in the rim and a cavity formed by the first and second chamber walls, and the rim, wherein a free vortex is created when there is a flow into the cavity through the plurality of vent holes. | 05-28-2009 |
20090288384 | SYSTEM FOR REDUCING OIL CONSUMPTION IN GAS TURBINE ENGINES - A system for reducing oil usage from a sump in a gas turbine engine. Two sources of oil usage, which usage includes leakage and consumption, have been identified: (1) during idle, leakage of oil from an oil sump through seals and (2) during high-power operation, consumption of oil entrained in vent air exiting from the sump. At idle, the invention reduces pressure in the sump, to thereby increase airflow across the seals into the sump, to inhibit the oil leakage across the seals. At high power operation, the pressure reduction is terminated, but flow exiting the vent is artificially restricted. | 11-26-2009 |
