  • Publication number: 20210282948
    Abstract: A vascular prosthesis is described, having blunted wire ends. The blunted wire ends can take on a variety of configurations including end caps, bent ends, curved ends, or eyelets. The novel ends provide a smooth surface to contact the blood vessel walls thereby reducing the risk of trauma during placement of the prosthesis.

  • Patent number: 11039735
    Abstract: A surgical sheath for use in endoscopic trans-nasal or intra-ocular surgery is made of a braid material. The sheath may be manufactured by placing a length of braided tube material over a mandrel. The braid material is conformed to the shape of the mandrel and is then heat set. An atraumatic end may be made by folding or rolling one or both ends of the sheath. A coating may also optionally be applied to the braid material. The sheath reduces collateral trauma to the tissues in the surgical pathway.

  • Publication number: 20210137364
    Abstract: A surgical sheath adapted for use in the nasal cavity has an elongated hollow body made of a braided material having interstitial spaces with a dimension of 0.25 mm to 1.50 mm. The interstitial spaces filled with a filling material, such as silicone. The sheath has a low profile configuration during placement into the naris, and may be stretched into an expanded configuration. In methods of placing the sheath in the naris, the sheath is folded and then pulled into the naris using a surgical tool.

  • Patent number: 10470647
    Abstract: A surgical sheath for use in endoscopic trans-nasal or intra-ocular surgery has an angle section joined to a conical section, with the conical section having a central axis not parallel to a central axis of the angle section. A body section is joined to the angle section, with the body section having a length at least twice the length of the angle section. The conical section, the angle section and the body section may be a flexible or compliant material. The sheath reduces collateral trauma to the tissues in the surgical pathway.
