  • Patent number: 11202895
    Abstract: The present invention generally relates to systems and methods for delivering and/or receiving a substance or substances such as blood, from subjects, e.g., from the skin and/or from beneath the skin. In one aspect, the present invention is generally directed to devices and methods for receiving or extracting blood from a subject, e.g., from the skin and/or from beneath the skin, using devices containing a fluid transporter (for example, one or more microneedles), and a storage chamber having an internal pressure less than atmospheric pressure prior to receiving blood. In some cases, the device may be self-contained, and in certain instances, the device can be applied to the skin, and activated to receive blood from the subject. The device, or a portion thereof, may then be processed to determine the blood and/or an analyte within the blood, alone or with an external apparatus.

    Abstract: A new minimally invasive surgical approach is proposed that contemplates a method and apparatus for tightening lax skin without visible scarring via a device in various surgical procedures such as plastic surgery procedures. In some embodiments, the device is a single use disposable instrument. This approach circumvents surgically related scarring and the clinical variability of electromagnetic heating of the skin and performs small multiple pixilated resections of skin as a minimally invasive alternative to large Plastic surgical resections of skin. This approach can also be employed in areas of the body that are currently off limits to plastic surgery due to the visibility of the surgical scar. In addition, the approach can perform a skin grafting operation by harvesting the transected incisions of skin from a tissue site of a donor onto a skin defect site of a recipient with reduced scarring of the patient's donor site.

  • Patent number: 8864788
    Abstract: A patient's pharyngeal wall is treated by inserting an expander member into the airway and positioning an active portion of the expander member in opposition to portions of the pharyngeal wall to be treated. The expander member is activated to urge the wall portions outwardly to an outwardly displaced position. The expander member is then deactivated while leaving the wall portions in the outwardly placed position and the expander member is removed from said airway. A further aspect of the treatment includes stabilization of at least a portion of the pharyngeal wall after compression of portions of the wall.

  • Patent number: 8864743
    Abstract: Angioplasty and other dilatation devices are provided with scoring elements which incorporate a drug to be delivered to a body lumen, typically a blood vessel. The non-cutting scoring elements have drugs and other active substances coated over a portion thereof or incorporated within internal structure of the element so that the drug is released into the luminal wall closely associated diseased regions of the body lumen as the non-cutting scoring structure is radially expanded into the wall.

  • Publication number: 20140294919
    Abstract: The present invention relates to efficient devices for administration of pharmaceutical agents into the skin of the human body. In particular the present invention provides devices for vaccination into the skin. The present invention provides a pharmaceutical agent delivery device having skin-piercing portion comprising a solid reservoir medium containing the pharmaceutical agent, wherein the reservoir medium is coated onto the skin piercing portion. Alternatively, the skin piercing portion may consist of the solid pharmaceutical agent reservoir medium. The pharmaceutical delivery devices are proportioned such that agent is delivered into defined layers of the skin, and preferred delivery devices comprise skin-piercing portions that deliver the pharmaceutical agent into the epithelium or the dermis. Preferred reservoir media comprise sugars, and in particular stabilising sugars that form a glass such as lactose, raffinose, trehalose or sucrose.

  • Publication number: 20140276378
    Abstract: Provided herein is a microstructure array comprising a plurality of dissolving microstructures such as microprojections attached to a base. The plurality of microstructures comprise an active agent in a biocompatible and water-soluble matrix, where the water-soluble matrix preferably comprises a polysaccharide polymer and a sugar alcohol, and the base typically comprises a non-water soluble matrix. The plurality of microstructures, upon penetration of the subject's skin, undergo dissolution to deliver the active agent. Also provided are related microstructure formulations, in dried and liquid form, methods for preparing the above-described microstructure arrays, and methods for administering an active agent by application of a microstructure array as provided herein to a subject's skin, among other features.
