  • Patent number: 10828387
    Abstract: A method of sealing a durotomy from which cerebrospinal fluid is leaking. A durotomy sealant dressing is prepared by applying an active agent to a dextran base. The durotomy sealant dressing is applied to a durotomy. At least a portion of the durotomy sealant dressing dissolves. The durotomy is sealed with the dissolved durotomy sealant dressing to substantially prevent cerebrospinal fluid from flowing through the durotomy.

  • Publication number: 20200215223
    Abstract: A surgical joint replacement kit including a first joint replacement component and a surgical sealant. The first joint replacement component is capable of being implanted to replace a joint between a first bone and a second bone. The first bone is cut in conjunction with implanting the first joint replacement component. Cutting the first bone causes a bodily fluid to flow from the first bone. The surgical sealant includes an electrospun dextran base and an effective amount of at least one of fibrinogen and thrombin. The at least one of fibrinogen and thrombin is applied to the electrospun dextran base to form the surgical sealant. The surgical sealant is capable of staunching the flow of the bodily fluid from the first bone.

  • Publication number: 20180361012
    Abstract: A method of forming a hemostatic product. A solution is formed with a polymeric material. An electrospinning system is provided having a first nozzle and a second nozzle. The polymeric material solution is passed through the first nozzle and a hemostatic agent is passed through the second nozzle to form an electrospun fiber in which the polymeric material at least partially covers the hemostatic agent. The electrospun fiber is deposited on a support to form the hemostatic product.

  • Patent number: 9597425
    Abstract: A method of forming hemostatic sheets. Dextran and water are mixed to form a dextran-water mixture. The dextran-water mixture is formed into a first support layer. Fibrinogen and thrombin are mixed to form a fibrinogen and thrombin mixture. The fibrinogen and thrombin mixture is dispersed on the first support layer to form a hemostatic sheet.

  • Patent number: 8916190
    Abstract: A method of inducing hemostasis in a wound using a hemostatic product. A dextran support is provided. At least one hemostatic agent stabilizer is mixed with at least one hemostatic agent to form a hemostatic agent and stabilizer mixture. The at least one hemostatic agent includes at least one of thrombin and fibrinogen. The hemostatic agent and stabilizer mixture is associated with the dextran support. The hemostatic product is applied to the wound in which a bodily fluid is present. The at least one hemostatic agent is released from the hemostatic product to induce hemostasis in the wound.

  • Patent number: 6964643
    Abstract: Therapeutic devices and methods according to embodiments of the invention alleviate e.g. urinary incontinence in female and male patients. Suction or vacuum, for example, is applied to the genital region, clitoris or clitoral region, the external urethral orifice, and/or other designated areas, e.g. physically stimulating the sacral/pudendal nerves and/or nerve roots and alleviating incontinence. Such embodiments also can encourage or cause clitoral engorgement, or otherwise promote blood flow in the genital region. Vacuum or suction applied to e.g. the clitoris creates a negative pressure in the clitoris that is lower than the systolic blood pressure, tending to promote engorgement of the clitoris with blood. Aspects of the invention are applicable not only to treatment of urinary and fecal incontinence, but also to the treatment of female sexual dysfunction. Aspects of the invention are also applicable to treatment of male incontinence and male erectile dysfunction.
