Abstract: The present disclosure provides an apical connector for use in a heart wall. The apical connector may include a port defining an aperture therethrough, an anchoring device extending distally from the port and configured for advancing at least partially through the heart wall, and a cannula configured for advancing through the aperture of the port and at least partially through the heart wall. The cannula may include a locking tab configured to engage the port and lock the cannula with respect to the port.

Abstract: An element of eyewear with a detachable lens portion comprising a first eyewear portion comprising a lens portion, a second eyewear portion comprising a frame portion, at least one projection that extends from the lens portion, and at least one aperture in the frame portion whereby the lens portion can be removably and replacably coupled with the frame portion. The at least one projection can be formed of resiliently compressible material. A plurality of projections can extend from the first eyewear portion, and a plurality of aligned apertures can be provided in a bridge segment of the frame portion. The projections can be longer than the bridge segment is thick such that distal ends of the projections will contact the forehead of the wearer to space the bridge segment therefrom. The element of eyewear can be an eye shield with a panel of translucent material comprising the lens portion.

Abstract: A mask and a method for producing a mask that includes a cover material for covering a portion of a face of a wearer and a hypoallergenic, anisotropic elastic material for securing the cover material to the face of the wearer.

Abstract: A face mask and a method for producing a face mask that includes a cover material adapted for disposal over a portion of the face of a wearer and at least one band made of a hypoallergenic, anisotropic composite elastic material, wherein the band is attached to the cover material so as to firmly, yet comfortably, secure the mask to the face of the wearer.

Abstract: The present air tubes include a resistive element which is located in the hollow space of the tubular portion. This resistive element is adapted for providing a linear resistance-versus-pressure response is sized and adapted to cause a pressure difference or differential as air flows in the hollow space across this element. The resistive element includes a planar member having a first face and a second face, and a circular parameter connecting the first face to the second face. An aperture is formed in a center of the planar member for connecting the first face to the second face. A plurality of slots in the planar member extend radially from the aperture, thereby forming a plurality of hinged windows in the planar member. Each of the slots includes a central end and a distal end. The resistive element further includes a plurality of hinge slots. Each hinge slot is connected to a distal end of a slot, and extends generally perpendicularly to an axis of the slot.

Abstract: A windshield wiper blade cleaning device is disclosed having a channel for receiving the tip of a wiper blade, the channel having a frictional base for removing dirt from the tip of the blade as the blade is drawn longitudinally through the channel. In an alternate embodiment, the channel also has frictional walls for cleaning the sides of the blade. In described embodiment, the base and/or walls are made frictional by means of projections, filaments, or abrasive materials.

Abstract: A face protector that includes a face mask and a transparent member, the transparent member can be adjustably positioned relative to the face of the wearer. The face mask includes fasteners for securing the mask to the face of the wearer, and the transparent member is affixed to the face mask by a structure that allows the transparent member to be positioned at a plurality of distances from the mask.

Abstract: Face shield for protecting a wearer's face from spatters. The shield includes a flexible, transparent portion sized to cover the face and a flexible spacer portion for contact with the wearer's forehead to provide adequate clearance of the transparent flexible portion away from the wearer's face. When worn, the flexible spacer portion substantially completely seals the top portion of the shield to prevent spatters from reaching the face from the top, that is, through the portion occupied by the spacer. The face shield may also include a mask structure to cover the nose and mouth of the wearer.
