The invention provides an implantable system for managing urinary incontinence. The system includes a sling with an elongate body member having a proximal portion, a distal portion and an intermediate portion. The intermediate portion is configured to be positioned underneath urethra of a subject for providing an adequate support to prevent leakage of urine during a stress event. The system may include a pressure sensor communicatively coupled with the elongated body member and configured to be positioned in an abdominal cavity and adapted to sense an increase in intra-abdominal pressure. The pressure sensor generates a first signal that is indicative of a change in the intra-abdominal pressure upon occurrence of the stress event. The system includes a processing circuit to process the first signal sensed by the pressure sensor. The processing circuit is configured to generate a second signal causing an adjustment of tensioning force in the elongate body member thereby changing magnitude of a supporting force to the urethra.

An artificial tongue is provided. The artificial tongue includes tongue tissue formed by a bioprinting process, an antenna embedded within the tongue tissue and configured to wirelessly receive power from an external device, a processor embedded within the tongue tissue and operatively coupled to the antenna, and a piezoelectric element embedded within the tongue tissue and operatively coupled to the processor. The piezoelectric element is configured to deform in response to an applied electric bias, and the processor is configured to cause the electric bias to be applied to the piezoelectric element based on the power received by the antenna.

A method and apparatus is provided for creating a modified tissue graft, wherein an anatomical site at which the modified tissue graft is to be placed is identified, desired characteristics for the modified tissue graft are identified based at least upon the anatomical site, one or more types of graft modifications and regions of the tissue graft to be modified are identified to achieve the desired characteristics; and at least a first area and a second area of the exterior surface of the tissue graft are modified by compressing, cutting and/or removing one or more portions thereof to create first designed surface features which cause the tissue graft to have first characteristics in the first area and second designed surface features which cause the tissue graft to have second characteristics in the second area.

The present disclosure relates generally to hernia repair, and more specifically to forming a custom fitted mesh based on a topographical map of at least one portion of a patient's abdominal cavity. Some specific aspects of the present disclosure relate to exemplary methods, systems, devices and computer readable mediums for forming a custom fitted mesh based on a topographical map of the at least one portion of the patient's abdominal cavity.

A method for producing bone grafts using 3-D printing is employed using a 3-D image of a graft location to produce a 3-D model of the graft. This is printed using a 3-D printer and a printing medium that produces a porous, biocompatible, biodegradable material that is conducive to osteoinduction. For example, the printing medium may be PCL, PLLA, PGLA, or another approved biocompatible polymer. In addition such a method may be useful for cosmetic surgeries, reconstructive surgeries, and various techniques required by such procedures. Once the graft is placed, natural bone gradually replaces the graft.

A system for selecting a preferred intraocular lens for implantation into an eye includes a controller having a processor and a tangible, non-transitory memory. The controller is configured to obtain diagnostic data of the eye, and obtain historical data composed of historical sets of patient data. The controller is configured to analyze individual risk factors based on the diagnostic data and obtain a weighted combination of the individual risk factors. A respective satisfaction metric for the plurality of intraocular lenses is generated based on the historical data. A preferred intraocular lens may be selected based in part on the respective satisfaction metric and the weighted combination. A visual simulation for each of the plurality of intraocular lenses may be performed, based in part on the diagnostic data. The visual simulation may incorporate an impact of the tear film data.

A stent for insertion into an intracranial blood vessel of the cerebral venous sinus system includes a proximal end, a distal end, a body between the proximal end and the distal end, the body comprising a plurality of wires in a closed pattern, wherein the stent is configured for insertion into an intracranial blood vessel of the cerebral venous sinus system. The stent is further capable of being repositioned, retrieved/re-sheathed, and removed for more precise delivery.

A customized guide includes a body having a shape corresponding to a main vessel in biological tissues that includes the main vessel and an accessory vessel branching from the main vessel, and an indicator provided in the body to indicate a branching location of the accessory vessel.

A method for creating a personalized stent or stent graft for a blood vessel with a saccular aneurysm includes: receiving a 3D model of the blood vessel with the saccular aneurysm; and generating a model of a personalized stent or stent graft that comprises a net shaped to fit along internal walls of the blood vessel and a covering positioned with respect to the net such as to cover an ostium of the aneurysm.

A method of constructing a replacement valve for repairing a heart having an annulus separating upstream and downstream regions. The method includes obtaining a representative perimetrical length of the annulus and fabricating a frame having a hub and legs extending outward from the hub to anchors axially offset from the hub. The method includes fabricating an annular band having a circumferential length corresponding to the representative length and attaching the band to the legs. The method includes forming a flexible component having a convex face having a margin and an axially offset region. And a concave face and connecting the offset region to the hub and portions of the margin to the band and/or a portion of the frame. The valve component moves to an open position when upstream pressure is greater than downstream pressure and to a closed position when downstream pressure is greater than upstream pressure.
