  • Patent number: 11903816
    Abstract: Full contour absorbable implants for breast surgery redistribute breast volume between the breast's upper and lower poles in exact and desirable ratios. The implants preferably redistribute breast volume so that the upper pole breast volume is 20-40% of the total volume, and the lower pole breast volume is 60-80% of the total volume. The implants are also designed to provide specific curvatures to the poles of the breast, and to angulate the nipple areolar complex slightly skyward so that the patient's nipple is positioned at an angle above the nipple meridian reference line. The implants are designed to be transitory, with sufficient strength retention to allow transition from support of the breast by the implant to support by regenerated host tissue growing in and around the implants, without any significant loss of support during or subsequent to remodeling. The implants may optionally be used with permanent breast implants.

  • Patent number: 11779455
    Abstract: Breast fixation devices for use in breast reconstruction and breast augmentation limit the rotation or movement of breast implants after implantation that results in an unnatural appearance of the breast. The breast fixation devices can include a thin-walled enclosure in the shape of a pouch. A breast implant is secured inside the pouch to limit movement by applying compression to the breast implants, or using a mating or interlocking mechanism between the pouch and breast implant. The pouches containing the breast implants are implanted in the breast. Tissue in-growth into the pouch limits movement of the pouch-breast implant assembly and thereby limits rotation, migration, and displacement of the breast implant. The pouches preferably comprise poly-4-hydroxybutyrate or copolymer thereof.

The implants preferably redistribute breast volume so that the upper pole breast volume is 20-40% of the total volume, and the lower pole breast volume is 60-80% of the total volume. The implants are also designed to provide specific curvatures to the poles of the breast, and to angulate the nipple areolar complex slightly skyward so that the patient's nipple is positioned at an angle above the nipple meridian reference line. The implants are designed to be transitory, with sufficient strength retention to allow transition from support of the breast by the implant to support by regenerated host tissue growing in and around the implants, without any significant loss of support during or subsequent to remodeling. The implants may optionally be used with permanent breast implants.

  • Patent number: 11116620
    Abstract: Devices, systems, and methods for delivering prosthesis implants into surgically-created implant pockets in a subject and for preventing capsular contracture resulting from surgical insertion of prosthesis implants. The device may include a delivery member operable to wrap around the implant thereby forming a conforming cavity around the implant that conforms to the shape of the implant. The delivery member is also operable to propel the implant from the conforming cavity into the implant pocket in the subject upon the application of mechanical force to the delivery member. The device also includes a shielding member coupled with the delivery member. The shielding member is operable to shield the implant from at least a portion of the dissection tunnel connecting the incision to the implant pocket during delivery of the implant to the implant pocket.

  • Patent number: 11096771
    Abstract: A device having a structured coating for adhering to rough, in particular biological, surfaces, includes a carrier layer, wherein a plurality of protrusions is arranged on the carrier layer, which protrusions each comprise at least a shaft having an end face pointing away from the surface, and wherein a further layer is arranged at least on the end face, wherein the layer has a different modulus of elasticity than the protrusion in question. The further layer can also fill the intermediate spaces between the protrusions such that an internal structured coating is produced.

  • Patent number: 11090146
    Abstract: A size adjustable cover used for soft tissue reinforcement which is adapted to envelop an implantable device, such as a breast implant, in a surgical application. The cover is formed using a circular two-dimensional implantable matrix material having an inner circle and a plurality of fringes which radiate circumferentially from the inner circle. The implantable device is positioned upon the inner circle, and the plurality of fringes are folded inwardly to form an overlapping implant pocket which envelops the implantable device. Each fringe further has a punched opening, allowing a loop of suture thread to link each fringe together. Certain fringes are excluded from the loop to create stabilization tabs which radiate from the inner circle and are attached to a site of host implantation to stabilize the cover and the implantable device within.

  • Patent number: 11083564
    Abstract: A prosthetic insertion apparatus and related methods of use in delivering filled prosthetic bladders through a skin incision and into a surgical cavity or pocket. The prosthetic insertion apparatus imparts control and retention properties to a surgical professional such the prosthetic bladder can be oriented and manipulated into the surgical cavity without risk of inadvertent dropping of the prosthetic bladder and without imparting damaging stress or torque to the bladder. Suitable materials can be utilized that are selected as having advantageous properties including lubricity, rigidity, easily sterilizable, and high strength.

  • Patent number: 11065075
    Abstract: Systems and methods for an extended tissue expander according to various aspects of the present technology may function in conjunction with a graft material for temporary implantation into a patient to form a pocket for a permanent implant. Systems and methods may comprise an extended tissue expander comprising an extension portion that may be integral to a posterior section of a shell of the extended tissue expander, wherein the extension portion extends from the posterior section forming an at least partially continuous annular rim around the circumference of the shell. The graft material may overlay an anterior portion of the shell and may be coupled to the at least partially continuous annular rim with bioabsorbable sutures. Upon implantation, the shell may be partially filled with a filler material until the graft material is gently pressed against a posterior portion of the patient skin flap, promoting its integration.

  • Patent number: 10945831
    Abstract: A dermal tissue allograft includes a dermal matrix having a profile including first and second vertices, a first imaginary axis extending between the first and second vertices, a first peripheral edge extending along a continuous path from the first vertex to the second vertex on a first side of the first imaginary axis, and a second peripheral edge extending along a continuous path from the first vertex to the second vertex on a second side of the first imaginary axis. The first peripheral edge includes an apogee, a convex portion, and a concave portion. The convex and concave portions meet at a transition point located on the first peripheral edge between its apogee and the second vertex. The second peripheral edge includes an apogee and is convex. The second perpendicular distance is greater than the first perpendicular distance. The dermal matrix has a substantially uniform thickness across its profile.

  • Patent number: 10926075
    Abstract: An implantable portal includes a septum that has embedded therein an indicia adapted to identify at least one characteristic of the portal. The indicia may be formed as an impression at a base layer of the septum, and is filled with a radiopaque material. The septum base layer is covered by liquid silicone, which bonds with the septum base layer when solidified, so that an integral one-piece septum, with the identifier indicia embedded therein, is effected. The indicia embedded septum is fitted to the reservoir housing of the portal for providing identification information for that portal. The septum embedded indicia is viewable visually and also by x-ray or computer tomography imaging.
