Abstract: Medical devices and methods for making and using medical devices are disclosed. An example medical device may include an access valve that may be retrieved after implantation. The access valve may include a frame having a lumen, a self-expandable member extending through the lumen, and an elastic membrane extending through the lumen and a second end of the frame to releasably seal the lumen. The access valve may releasably attach to a wall of a patient and releasably seal an opening through the wall. The access valve may be attached to the wall by placing the frame adjacent the wall, extending the self-expandable member through the opening in the wall, and expanding the self-expandable member such that the self-expandable member applies a first force against the wall and a second force opposite the first force against the frame to sandwich the wall between the self-expandable member and the frame.

Abstract: Implants can be used as flow diverters for treating aneurysms. Implants can include a stabilizing frame for anchoring the implant and an occluding element for diverting blood flow from the aneurysm neck. The stabilizing frame can have two parts, the first part sized to anchor within the sac of the aneurysm and the exterior part sized to anchor against a region of the blood vessel wall adjacent the aneurysm neck. The occluding element can be attached to the interior frame and positioned to occlude the aneurysm neck. The implant can have a central node that can be positioned near the center of the aneurysm neck at which the interior frame is attached to the exterior frame and from which the interior frame and the exterior frame extend.

Abstract: A speed square is provided including a triangular flat plate having measurement markings indicated on at least one face, a T bar affixed to, and extending along, the length of a first side of the triangular flat plate, and an extension element hingedly connected to an end of second side of the triangular flat plate opposite the T bar. The extension element having measurement markings indicated on at least one face, such that the measurement markings of the triangular flat face continue on the extension element.

Abstract: A device for enabling controlled movement of ions between a first ion-containing fluid and second ion-containing fluid comprises at least one cationic exchange membrane positioned between the first and second ion-containing fluids, and at least one anionic exchange membrane in parallel with the at least one cationic exchange membrane positioned between the first and second ion-containing fluids. The one or more of the at least one cationic exchange membrane and the at least one anionic exchange membrane is a membrane electrode assembly comprising an ion exchange membrane, and one or more permeable electrodes embedded within the ionic exchange membrane. The number of cationic exchange membranes and the number of anionic exchange membranes is the same, and the ions move through the membrane electrode assembly in response to a variable capacitive charge.

Abstract: A measuring tape device may include a housing having an aperture, a reel assembly, a blade having a first end configured to extend from the housing through the aperture and a second end configured to be wound on the reel assembly, and an end hook disposed at the first end of the blade. The end hook may have a front face that faces away from the aperture and a rear face that faces toward the aperture. A high friction surface including grains may be disposed over at least a portion of a surface of the rear face.
