Abstract: In the cell case of the power storage cell according to the present disclosure, the cylindrical main body portion is formed by forming a film into a cylindrical shape, and the first opening portion and the second opening portion are formed at both ends thereof, respectively. The first sealing body closes the first opening portion. The second sealing body closes the second opening portion. The first sealing body includes an outer peripheral face that is in contact with an inner peripheral face of the cylindrical main body portion. The outer peripheral face includes a main body surface portion and a protruding portion. The main body surface portion extends in parallel to a first direction in which the first opening portion and the second opening portion are arrayed. The protruding portion protrudes from the main body surface portion toward the cylindrical main body portion.

Abstract: A power storage module has a case including a case body and at least one partition portion. The case body surrounds a plurality of electrode assemblies. The partition portion is located between the electrode assemblies adjacent to each other to partition an accommodation space of the case body. In the accommodation space of the case body, the partition portion forms a first compartment and a second compartment adjacent to the first compartment with the partition portion interposed between the first compartment and the second compartment. A first cooling path and a second cooling path are formed in the case, the first cooling path extends in a portion 10 of the case that faces the first compartment without the second compartment in between, and the second cooling path extends in a portion of the case that faces the second compartment without the first compartment in between.

Abstract: A power storage module includes a case that houses a plurality of electrode assemblies. The case includes a case body and at least one partition portion. The case body surrounds the plurality of electrode assemblies. The partition portion is located between the electrode assemblies adjacent to each other to partition an accommodation space of the case body. The partition portion includes a pair of resin layers and a metal layer. The pair of resin layers is formed integrally with the case body and the resin layers are arranged in a first direction. The metal layer is located between the resin layers and extends in a direction orthogonal to the first direction.

Abstract: An apparatus for separating a balloon from a catheter member of a balloon is capable of melting and breaking a heat-meltable connecting member through which the balloon is connected to the catheter body by causing an electric current to flow between at least a pair of electrodes arranged on or in the vicinity of the connecting member. The apparatus has impedance measuring means for measuring the impedance of an electrode circuit including a pair of electrodes and lead lines connected to the electrodes, and judging means for comparing the measured value of the impedance with a predetermined reference range and capable of producing an abnormal signal when the measured value of the impedance does not fall within the predetermined reference range.

Abstract: This invention provides a releasable balloon catheter having a portion cuttable by torsion or a portion cuttable by heating at or near a joint part between the catheter body and the balloon. When the balloon catheter is inserted into a vessel and carried to the desired site by the blood stream and the balloon is inflated by introducing a fluid into the balloon and is fixed at the desired site face-to-face with the wall of the vessel, torsion or heating causes the balloon to be released from the catheter body. The balloon catheter is used to embolize vascular lesions.

Abstract: This invention provides a releasable balloon catheter having a tube cuttable by torsion or a tube cuttable by heating at a joint part between the catheter body and the balloon. When the balloon catheter is inserted into a vessel and carried to the desired site by the blood stream and the balloon is inflated by introducing a fluid into the balloon and is fixed at the desired site face-to-face with the wall of the vessel, torsion or heating causes the balloon to be released from the catheter body.

Abstract: Disclosed is a balloon catheter including a catheter and a balloon bonded to the catheter through an adhesive in which the outer surface of the balloon is contiguous to the outer surface of the catheter through a smooth surface. In this balloon catheter, the balloon is tightly fixed to the catheter and there is no risk of separation of the balloon. Further, since the balloon catheter has a smooth surface in the connecting portion, insertion of the balloon catheter into a blood vessel and withdrawal of the balloon catheter from the blood vessel can be performed very easily and smoothly. Accordingly, this balloon catheter can be used very advantageously for the angiography.
