A positioning device for providing access to a ventricle of a heart. In one embodiment, the device includes a cup positionable over an apex of the heart and at least a first access valve in the cup for accessing an entry point to the ventricle of the heart.

Auto-closure apical access positioner device and method

A novel occluder application and clip device for treatment of embolic stroke caused by atrial fibrillation uses multiple sutures in a non directional handle to affix the occlusion device to the applicator and manipulate the occluder from an open and receiving position to a closed and occluding position. The occluder is retained in place by a clamping means related to locks retainers, resilient material or otherwise. An actuator mechanism is used to manipulate the occluder to a locked or occluding position. The applicator with the occluder attached has a low profile and remote manipulations to allow the occluder to be delivered to the clamping location within a patient through a small incision or delivery port such as a trocar cannula or the like.

Methods and devices for occlusion of an atrial appendage

Suction-assisted tissue-engaging devices, systems, and methods are disclosed that can be employed through minimal surgical incisions to engage tissue during a medical procedure through application of suction to the tissue through a suction member applied to the tissue. A shaft is introduced into a body cavity through a first incision, and a suction head is attached to the shaft via a second incision. The suction head is applied against the tissue by manipulation of the shaft and suction is applied to engage the tissue while the medical procedure is performed through the second incision. A system coupled to the shaft and a fixed reference point stabilizes the shaft and suction head. When the medical procedure is completed, suction is discontinued, the suction head is detached from the shaft and withdrawn from the body cavity through the second incision, and the shaft is retracted through the first incision.

Methods and apparatus providing suction-assisted tissue engagement through a minimally invasive incision

The invention provides a system for occluding a left atrial appendage of a patient. The system can include a ring occluder that can be positioned around the left atrial appendage and a ring applicator to position the ring occluder with respect to the left atrial appendage. The system can also provide a tissue-grasping tool that is separable from the ring applicator tool.

Device for occlusion of a left atrial appendage

Disclosed is an apparatus for oxygenating and controlling the temperature of blood in an extracorporeal circuit. The apparatus has an inlet and an outlet that is located radially outward from the inlet in order to define a flowpath through the apparatus. The apparatus comprises: a core that is substantially centrally located in the apparatus and to which blood from a patient can be supplied through the inlet; a heat exchanger comprising a plurality of heat transfer elements that are arranged around the core and between which blood from the core can move radially outward; and an oxygenator comprising a plurality of gas exchange elements that are arranged around the heat exchanger and between which blood from the heat exchanger can move radially outward before exiting the apparatus through the outlet.

Radial design oxygenator with heat exchanger

The invention provides a system and method for harvesting a vessel section. The system comprises a vessel support member, a handle, and a tubular cutting device. The vessel support member is introduced into the vessel section to be harvested. The tubular cutting device may comprise an outer tubular member or an outer and an inner tubular member. The outer tubular member carries at least one cutting element. The tubular member or members are advanced over the vessel section and vessel support member to core out the vessel section and tissue adjoining the vessel section.

Minimally invasive coring vein harvester

Tissue stabilizers including a clamp assembly, a turret assembly, an articulating arm having a tension element extending therethrough, a collet assembly and a head-link assembly are disclosed. Methods of stabilizing tissue are also disclosed.

Methods and devices for stabilizing tissue

This invention provides a heart positioning device, method and system for positioning, manipulating, holding, grasping, immobilizing and/or stabilizing a heart. The heart positioning device may include a suction head and a shaft with a means for remotely changing the position of the head from a first position axially aligned with the shaft to a second, unaligned position and a sleeve slideably positioned on the shaft and sized to receive the suction head in a compressed condition.

Method and system for organ positioning and stabilization

Method and formulation for providing multiple sources of migratory corrosion inhibitors to metallic reinforcements embedded in concrete through addition of the inhibitors to the concrete mix. First and second sources of inhibitors are provided with the first source consisting of a powdered corrosion inhibitor consisting of sodium sebacate, potassium sebacate, dicyclohexylammonium nitrite, sodium nitrite, zinc gluconate, sodium gluconate, and calcium nitrite. The second source consists of an in-situ coextruded blend of a migratory corrosion inhibitor in a resin matrix, the second source consisting of a coextruded blend which includes an alkali metal salt of a dibasic acid containing from 8 to 12 carbon atoms together with migratory corrosion inhibitors consisting of alkali metal gluconates, zinc gluconate, and cyclohexylammonium benzoate, with the alkali metal in the inhibitors being sodium, potassium, or calcium. The total amount of corrosion inhibitor in concrete is between about 16 and 24 ounces per cubic yard, with the first source being between 70% and 80% by weight of the total corrosion inhibitor.

Migrating corrosion inhibitor fibers

Corrosion inhibiting thermoplastic alloys and methods of preparing same for use in fabricating molded articles with long-term corrosion protection. Masterbatches of nylon, polycarbonate, and polyethylene terephthalate high temperature engineering plastic resins together with selected corrosion inhibitor formulations are extruded for use in injection molding operations Molded articles are prepared from the high temperature engineering plastic resins and a solid phase corrosion inhibitor blended in situ, and wherein the resin consists essentially of nylon, polycarbonates, and polyethylene terephthalate, and wherein the corrosion inhibitor contains a blend of corrosion inhibitors such as cyclohexylammonium benzoate, sodium nitrite, benzotriazole, and sodium sebacate.

Corrosion inhibiting thermoplastic alloys

An improved method and/or process for preparing and handling formulations useful in metal treatment baths which includes packaging formulations useful in preparing and/or replenishing aqueous-based baths in water soluble pouches or containers. The present invention includes the selection of components effective in treating metallic surfaces, which may be blended and effectively stored in containers or pouches consisting of polyvinylalcohol film. The present invention reduces the necessity or frequency of personal hand contact by workers with these blends.
