Abstract: A wearable, open and pliable conforming MRI receiver coil system having an assembly of MRI imaging coils, each configured in a framework to simultaneously apply or position MRI receiver antennae and medical implements such as ultrasound transducers against the skull or skin of a patient. The system is configured to perform an MRI imaging and operation of the one or more medical implements simultaneously.

Abstract: A wearable, open and adjustable MRI head coil system having an assembly of support members, panels, or portions defining one or more access openings. The support members, panels, or portions can support, house, or otherwise include radiofrequency receiver antennae or imaging coils such that the assembly is positionable or wearable by a patient for MRI scanning. The radiofrequency receiver antennae or imaging coils, and other devices can be simultaneously in contact with a patient's head, thereby enabling use during diagnostic, therapeutic, surgical or other interventional procedures.

Abstract: A system for facilitating fluid connection between cannulae and a blood pump. The system includes a cannula having proximal and distal ends. The distal end of the cannula adapted to be in fluid communication with the circulatory system. The proximal end of the cannula configured to couple to an inlet of the blood pump. The system further includes a tunneling device configured to be inserted into a body of a patient to direct the proximal end of the cannula adjacent to the inlet for connection thereto. The cannula further includes a first connecting structure. The tunneling device further includes a second connecting structure. The first and second connecting structures are selectively engageable to allow connection and disconnection between the cannula and tunneling device.

Abstract: In a specialized sand bucket for use in golfing, the bucket is pivotably affixed to a durable metal handle and is covered by an easy-lifting, tight-fitting lid. The scoop fits easily inside for convenient carrying. A permanently affixed metal stand elevates the bucket to a comfortable height and reduces the wear on the bucket when it is being carried by hand or in the back of a golf cart.

Abstract: A backup stem seal for a gate valve retains pressure in the body when the valve is in the closed position. The backup seal is secondary to the main stem seal assembly in the bonnet. It features metal-to-metal contact between surfaces that are radially oriented or sloping and further can contain a retaining groove for a seal ring in one or both the opposed metal-to-metal surfaces. The groove can be formed to better retain the ring from damage from flowing fluids when the valve is open. A passage through the bonnet may be used to test for leakage past such seal. The backup seal allows maintenance of the main stem seal without removing the valve from service.

Abstract: A sealing system for a flow tube to keep cement from getting around it to the flapper when the safety valve is in the open position is disclosed. Seals are provided at opposed ends of the flow tube so that the power spring and the flapper will not get fouled with cement pumped through the flow tube in wells that are completed through a production string with the safety valve in place. The seals may be mounted to the flow tube or the surrounding body. A unique seal construction is also disclosed. The force acting on the flow tube to hold the valve open also helps to apply a force against the lower seal adjacent the flapper.

Abstract: A low pressure backseat sealing apparatus having a flexible sealing lip which contacts the backseat prior to contact between a stem shoulder and the backseat, with the stem shoulder positioned above the flexible lip, thereby limiting stem movement while allowing internal valve pressure to achieve a seal between the flexible lip and the bonnet.
