  • Patent number: 11844687
    Abstract: A method of making an implantable prosthesis includes applying a gelling enhancer layer over an inner surface of a wall of a silicone shell having anterior and posterior walls surrounding an interior volume. The method includes filling the interior volume of the shell with a silicone gel and curing the silicone gel. The cured silicone gel that is located within a zone that is in the vicinity of the gelling enhancer layer has a higher level of cohesiveness than the cured silicone gel that is located outside the zone. The zone of the silicone gel having the higher level of cohesiveness has a thickness of 2-10 mm. The silicone gel located outside the zone has a first concentration level of a gelling enhancer and the silicone gel located within the zone has a second concentration level of the gelling enhancer that is 5%-300% greater than the first concentration level.

  • Publication number: 20230371944
    Abstract: A composite suture needle configured for passing through a smaller cannula used in minimally invasive surgery includes a curved elongated body made of stainless steel. The curved elongated body has a proximal end and a distal end with a pointed tip. The composite suture needle includes a sheath overlying the curved elongated body. The sheath is curved for conforming to the shape of the curved elongated body. The sheath is made of a material that is more elastic than the curved elongated body. The pointed tip of the curved elongated body extends distally beyond the distal end of the sheath. The curved elongated body is made of stainless steel and the sheath is made of a material, such as nitinol, that is more elastic than the elongated body.

  • Publication number: 20230098318
    Abstract: An implant delivery sleeve comprises a tubular wall having a proximal end with a proximal opening, a distal end with a distal opening, and an implant delivery channel extending between the proximal and distal ends of said tubular wall. A plurality of bands interconnect portions of the tubular wall for constricting the implant delivery channel adjacent the distal end of the tubular wall. As an implant is advanced toward the distal end of the tubular wall, the constriction squeezes and/or deforms the implant for facilitating insertion into an incision that is smaller than the normal size of the implant.

  • Patent number: 11547401
    Abstract: A suture package includes a suture housing having a tray with a suture channel, and at least one suture disposed on the suture housing, whereby the suture includes a suture thread disposed within the suture channel of the tray. The package includes a suture straightening assembly including a suture dispensing path for removing the suture thread from the suture housing. The suture straightening assembly includes a first suture thread straightening section configured to apply a first flexing force within a first plane upon the suture thread as the suture thread is drawn along the suture dispensing path, and a second suture thread straightening section configured to apply a second flexing force within a second plane upon the suture thread as the suture thread is drawn along the suture dispensing path. The first and second planes extend along axes that define an angle relative to one another.

  • Publication number: 20220395643
    Abstract: A gas sterilizable syringe includes an enclosure having walls that define a fluid chamber. A flowable material is disposed within the fluid chamber of the enclosure. A plunger is assembled with the enclosure and is moveable toward a distal end of the enclosure for dispensing the flowable material. One or more apertures are formed in at least one of the walls of the enclosure. A gas permeable barrier covers at least one of the apertures formed in at least one of the walls of the enclosure for enabling sterilization gases to pass through the at least one aperture covered by the gas permeable barrier while preventing the flowable material from passing through the at least one of aperture. The gas permeable barrier is permeable to the sterilization gases and impermeable to the flowable material disposed within the fluid chamber of the enclosure.

  • Patent number: 11471268
    Abstract: An implantable prosthesis includes a silicone shell having an apex, a base, a radius located between the apex and the base, and a dome extending between the apex and the radius. The silicone shell has an outer surface and an inner surface that surrounds an interior volume of the silicone shell. A silicone gel material is disposed within the interior volume of the silicone shell. A gelling enhancer layer containing a gelling enhancer covers the inner surface of the silicone shell. After the silicone gel material has been thermally cured, the silicone gel material that is located within a zone that is in the vicinity of the gelling enhancer layer has a higher level of cohesiveness than the silicone gel material that is located outside the zone. The gelling enhancer contains crosslinker and/or platinum catalyst, such as a Karstedt catalyst.
