摘要:
Various devices, systems, and methods are capable of killing tumor cells by delivering cell-disrupting agents into a tumor in an inward direction from a peripheral border about the tumor. In some examples, a covering that includes one or more emissive elements encompasses at least a portion of a tumor such that the emissive element is directed inwardly toward the tumor so as to be able to introduce a cell-disrupting agent into the tumor. In further examples, the covering is incorporated into a glove.

Heat sensors can be positioned within the esophagus of a patient so as to monitor temperature changes during ablation procedures in the heart. Some heat sensors can include one or more fluid passageways that define an extended heat sensing region capable of detecting a change in the local temperature. Some heat sensors can be conformable to an inner surface of the esophageal wall to maintain contact therewith or to be in close proximity thereto.

Composite stent grafts can include separate components that are capable of being repositioned relative to each other in situ. In some examples, a stent and a graft that are attached to each other in an insertion package do not overlap each other. The graft and stent are moved relative to each other in situ.

In some arrangements, a pump for moving a fluid has one or more pump chambers and one or more flow control valves with diaphragm actuation regions. Motive fluid can activate the diaphragm actuation regions, and a pattern of fluid flow can be controlled by varying the pressure levels of the motive fluid.

A volleyball practice system that includes a support frame with an attached reduced size volleyball practice net, a catch net, a removable and selectively positionable suspended ball attached to the support frame by a plurality of tethers, and a selectively removable electronic speed sensor and indicator device attached to the support frame for indicating the speed of the volleyball as it travels transversely to a vertical planar surface of the practice net.

A heat exchanger apparatus enables the temperature of a liquid located external to the apparatus in a recirculation loop to be controlled by heat transfer within the apparatus. A manifold fitting is also provided for distributing fluid from multiple conduits to a single conduit.

A paired, expandable anastomosis device joins two vessels together and can expand and contract with changes in the size of the two vessels. The anastomosis device has two expandable rings with a plurality of holding tabs. The holding tabs of one ring are shaped to enable a graft vessel tissue to be everted through one of the rings and to be held on one of the rings. Similarly, the holding tabs of the other ring are shaped to enable a target vessel to be everted through the other ring and to be retained by the holding tabs. Once the graft and target vessels are loaded, the rings are adapted to be brought together to a position in which the graft and target vessels are anastomosed together.
