Patent number: 11931553Abstract: The present disclosure relates to medical delivery devices that include a barrel having an inner surface, and in at least one embodiment, the inner surface is hydrophilic. The medical delivery device may further include a stopper may having an elastomeric body, one or more fluoropolymer layers, and two or more ribs laminated to the one or more fluoropolymer layers. In some embodiments, the contact angle of the inner surface of the barrel is less than about 58°. Additionally, the stopper includes a sliding surface that is less than about 2.0 mm. The barrel provides inner surface that in combination with the fluoropolymer laminate or fluoropolymer film achieve high levels of air and liquid impermeability while also maintaining an acceptably low break loose force, low average glide force, and low glide force variation. In some embodiments, the compressibility stopper against the barrel is greater than about 7.9%.Type: GrantFiled: October 14, 2019Date of Patent: March 19, 2024Assignee: W. L. Gore & Associates, Inc.Inventors: Michael C. Berg, Daniel H. Todd, Eric J. Van Voorhees

Patent number: 9695258Abstract: Methods of adjusting the mechanical properties of a polymeric material may include forming a polymer network having a plurality of permanent cross-links and coupled to a plurality of reversible cross-links, wherein the polymer network has a shear storage modulus of greater than about 4×104 Pa; and heating the polymer network using a heat source to dissociate the reversible cross-links, wherein heating the polymer network reduces the shear storage modulus to less than about 4×104 Pa. In some embodiments, a polymeric material may include a polymer network comprising a plurality of permanent cross-links and coupled to a plurality of reversible cross-links that are dissociable with the application of a stimulus and associable with the removal of the stimulus, wherein the shear storage modulus of the polymer network is less than about 4×104 Pa in the presence of the stimulus and greater than about 4×104 Pa in the absence of the stimulus.Type: GrantFiled: June 30, 2014Date of Patent: July 4, 2017Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Randy A.
