  • 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: 20170136141
    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: 20160038627
    Abstract: A method of causing delayed hemostasis. A hemostatic product is formed by applying a hemostatic agent to a dextran support. The hemostatic agent is provided with at least one of a reduced concentration and a reduce availability. The hemostatic product is applied to a wound from which blood is being discharged. At least one foreign object or pathogen is proximate the wound. Hemostasis is progressively caused so that blood continues to be discharged from the wound to cause the at least one foreign object or pathogen to move away from the wound.

  • 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.

  • Patent number: 4008294
    Abstract: Ultra fine polypropylene fibers having a length of 1-100 microns and a diameter of 0.05-2 microns are admixed with a polyester resin composition comprising a polyester resin of a polyhydric alcohol and an unsaturated polycarboxylic acid admixed with a solvent such as styrene in an amount effective to cause the resulting thickened composition to have a thixotropic index of 1.5-8. The resulting thickened composition is useful for building or repairing fiber glass-polyester boats. The incorporation of such ultrafine polypropylene fibers in an epoxy resin composition also thickens the epoxy resin composition and causes it to have a thixotropic index of about 1.5-8.
