  • Publication number: 20260157650
    Abstract: A wearable monitor is configured for early detection of internal bleeding events and particularly hematomas after vascular catheterization including cardiac catheterization. The wearable monitor is placed over an access location following the vascular catheterization procedure and the wearable monitor system periodically runs diagnostic test to detect changes in the tissue around the vascular access location. An emitter device may input an emitter input into the tissue and a detector device may then measure the emitter input after it has passed through the tissue, an emitter output. A computer may receive the data from the detector device and operate a program that determines changes in the tissue and in particular, pooling of blood in the tissue. The emitters may be electrodes that input an electromagnetic input, or an ultrasound emitter that inputs ultrasound sound waves, or a Near IR emitter that emits Near IR electromagnetic radiation.

  • Patent number: 11707611
    Abstract: An implantable containment apparatus for receiving and retaining a biological moiety or a therapeutic device within a tissue bed is disclosed. The device includes a shaping element to maintain the device in a generally toroidal configuration and to return the apparatus to that configuration after deformation. The apparatus can be placed in a host tissue with minimal trauma to the patient. Methods for implanting and using the apparatus are also disclosed.

  • Patent number: 4207984
    Abstract: A decorative envelope packet which may be mounted on a wall, and includes detachable envelopes in the form of a plurality of stacked envelopes encased within a decorative coverlayer. The coverlayer extends along the entire back portion of the envelopes and is connected by wire staples to the stacked flap portions of the envelopes. The decorative coverlayer is folded about three fold lines so as to completely enclose the wire staples, and so as to at least partially cover the flap portions of the front of the decorative envelope packet. The total enclosure of the wire staples ensures that during shipment of the decorative envelope packets the wire staples of one packet does not damage the decorative printing on the coverlayer of the adjacent packet, and in addition, this arrangement prevents inadvertent nicking or cutting of the user's fingers by the clinched ends of the wire staples.
