A medical implant assembly and method having a medical implant, e.g. a breast prostheses, attached to a biological interface. The biological interface is comprised of a dermal material with capsular contracture inhibiting properties so that once the medical assembly is inserted into the host, the biological interface, which is intimately coupled to the implant, prevents / reduces capsular contracture formation around the implant. The biological interface comprises a plurality of apertures along its periphery, and attaches to the medical implant by receiving a plurality of attachment flaps or appendages located on the exterior surface of the medical implant within or through the apertures. The attachment of the biological interface is such that the assembly remains intact even where the attachment flaps loosen upon expansion of the implant after insertion into a host, as where the implant is therein injected to a desired dimension.

A dermal punch device for automatically extracting a sample of tissue of a predetermined size and shape from a body comprising a retractable cutter and a sutureless biopsy closure mechanism that includes a wound closure fastener member adapted to be disposed over a biopsy region after the performance of the biopsy, wherein wound closure fastener member is applied without the need of several instruments to seal the wound. The wound closure fastener member is dispensed by a sutureless biopsy closure dispenser located at the same distal end of the biopsy punch device surrounding the biopsy punch cutter assembly avoiding the need of separates instruments, reducing the wound closing steps and surgical procedure time.

A device is disclosed for the securement of dermal tissues. The device provides approximation and eversion of the tissue as well as the placement of a fixation element that bridges a wound. The fixation element may be produced in several fixed or dynamic configurations that may or may not alter the ability to engage tissue in response to stresses placed upon the fixation member post-deployment. The delivery device inserts the fastener percutaneously through the epidermis into the sub-dermal position without entering the wound margins with any part of the approximation portion of the delivery device.

Methods and systems for treating stretch marks through deep tissue tightening with ultrasound are provided. An exemplary method and system comprise a therapeutic ultrasound system configured for providing ultrasound treatment to a shallow tissue region, such as a region comprising an epidermis, a dermis and a deep dermis. In accordance with various exemplary embodiments, a therapeutic ultrasound system can be configured to achieve depth from 0 mm to 1 cm with a conformal selective deposition of ultrasound energy without damaging an intervening tissue in the range of frequencies from 2 to 50 MHz. In addition, a therapeutic ultrasound can also be configured in combination with ultrasound imaging or imaging / monitoring capabilities, either separately configured with imaging, therapy and monitoring systems or any level of integration thereof.

Disclosed herein is processed dermis graft for use in orthopedic surgical procedures. Specifically exemplified herein is a processed dermis graft comprising one or more bone blocks having a groove cut into the surface thereof, wherein said groove is sufficient to accommodate a fixation screw. Also disclosed is a method of processing dermis that results in a dermis derived implant suitable to replace a tendon or ligament in a recipient in need thereof. Other compositions and applications of a dermis derived implant, and methods of manufacture and use, are disclosed.

A method and system for providing ultrasound treatment to a deep tissue that contains a lower part of dermis and proximal protrusions of fat lobuli into the dermis. The invention delivers ultrasound energy to the region creating a thermal injury and coagulating the proximal protrusions of fat lobuli, whereby eliminating the fat protrusions into the dermis. The invention can also include ultrasound imaging configurations using the same or a separate probe before, after or during the treatment. In addition various therapeutic levels of ultrasound can be used to increase the speed at which fat metabolizes. Additionally the mechanical action of ultrasound physically breaks fat cell clusters and stretches the fibrous bonds. Mechanical action will also enhance lymphatic drainage, stimulating the evacuation of fat decay products.

Compositions and method for augmenting tissue after delivery to localized area. The compositions include a hydrogel and a dermal filler. The hydrogel can polymerize and / or crosslink upon a first trigger event. The dermal filler can also optionally crosslink upon a second trigger event.

A packaged medical device includes upper and lower flexible sheets, a lance body and a test strip. The lance body includes upper and lower surfaces, an opening that extends between the upper and lower surfaces and a dermal tissue penetration member that projects into the lance body opening. The test strip has an opening therethrough and is attached to the lance body lower surface such that the dermal tissue penetration member is operatively aligned with the test strip opening. The upper flexible sheet is attached to the lance body upper surface and covers the lance body opening, while the lower flexible sheet is detachably attached to the test strip and covers the test strip opening. The upper flexible sheet, lance body and test strip are configured such that, when the lower flexible sheet has been detached to uncover the test strip opening, the upper flexible sheet, lance body and test strip can be bent to deploy the dermal tissue penetration member from the lance body opening. A kit includes the packaged medical device described above and a deployment device for detaching the lower flexible sheet and bending the upper flexible sheet, lance body and test strip to deploy the dermal tissue penetration member. A method for deploying a dermal tissue penetration member of a packed medical device includes providing the packaged medical device described above, detaching the lower flexible sheet to uncover the test strip opening and bending the upper flexible sheet, lance body and test strip to deploy the dermal tissue penetration member.

The present invention relates to improved methods for filling the skin for cosmetic or medical purposes. Compositions comprising carboxymethyl cellulose (CMC), polyethylene oxide (PEO) and calcium ions can be made and have physical properties that depend on the amounts and types of CMC, PEO, and calcium ions to form ioniclaly cross-linked gels. Compositions can be formed into microspheres, coascervates, gels, or membranes. Gels, microspheres and coascervates can be injected directly into a site for dermal filling. Membranes can be surgically introduced, where they swell to form hydrated gels. After introduction, the dermal filler persists for a period of time and then can disintegrate and be removed from the body.

Method, system and apparatus for carrying out a controlled heating of dermis to achieve a percentage of linear collagen shrinkage. Implants are employed which preferably are configured as a thermal barrier defining support of an outwardly disposed support surface which carries one or more heater segments. Located along heating channels at the interface between dermis and next adjacent subcutaneous tissue, the structure protects the latter from thermally induced damage while directing heat energy into the former.
