摘要： A process of making a tack-free gel is disclosed comprising the steps of providing a mold defining a mold cavity, the mold cavity comprising a plastic material; pouring or injecting a molten gel having a high molding temperature into the mold cavity; and forming the tack-free gel as a thin layer of plastic of the mold cavity is melted over the gel. The forming step further comprises cooling the gel from the molten state to a solidified state. The melting temperature of the plastic material is lower than the molding temperature of the gel; and the higher the temperature differential, the greater the melting of the plastic material and the thicker the layer of the plastic material on the surface of the gel. The mold may be formed of low-density polyethylene (LDPE).

摘要： The invention is directed to a device and method for securing a passed surgical suture in a manner similar to a tied knot. The suture securing device comprises a male piece having a top portion, a center shaft having one end connected to the top portion, and an end member having a capturing feature connected to another end of the center shaft; and a female piece having a top end and a bottom end comprising a column being generally cylindrical in shape and forming a hollow opening along its length, wherein the opening slidingly receives the center shaft and a suture to be captured and held by the capturing feature, the suture being secured in place between the column and the center shaft. The assembled male and female pieces are irreversibly interlocked and form a lightly compressed, convoluted or tortuous pathway. The capturing feature is formed to engage and obliquely capture the suture from different angles.

摘要： The invention is directed to a device and method for securing a passed surgical suture in a manner similar to a tied knot. The suture securing device comprises a male piece having a top portion, a center shaft having one end connected to the top portion, and an end member having a capturing feature connected to another end of the center shaft; and a female piece having a top end and a bottom end comprising a column being generally cylindrical in shape and forming a hollow opening along its length, wherein the opening slidingly receives the center shaft and a suture to be captured and held by the capturing feature, the suture being secured in place between the column and the center shaft. The assembled male and female pieces are irreversibly interlocked and form a lightly compressed, convoluted or tortuous pathway. The capturing feature is formed to engage and obliquely capture the suture from different angles. The radii of the male and female pieces are preferably greater than the radius of the suture. The securing device may further comprise a link formed between the male and female pieces. The link may be a tether formed when the male and female pieces are formed. The link may be severed and removed after placement and assembling of the male and female pieces. In another aspect of the invention, a method for applying a suture securing device is disclosed comprising the steps of: (1) providing the suture securing device of the invention; (2) aligning the male piece and the female piece at a desired location for applying the suture securing device; and (3) pressing the center shaft of the male piece into the opening of the female piece. The method may further comprise the step of applying a compressive load on the male piece to dislodge an enlargement from an undercut of the female piece and to place the male piece and the female piece in a condition where they may be advanced to a desired position along the suture.
