Abstract: The present disclosure relates to compositions comprising a copolymer that includes a first monomer and a second monomer that is different from the first monomer, wherein both the first and second monomer are selected from the group consisting of 3-sulfopropyl acrylate potassium salt, sodium acrylate, N-(tris(hydroxyl methyl)methyl)acrylamide, and 2-acrylamideo-2-methyl-1-propane sulfonic acid. The present disclosure further relates to methods for preparing the copolymer compositions and shaped articles comprising the copolymers.

Abstract: A surgical portal assembly includes a portal adapted to provide access to underlying tissue and having a longitudinal opening extending along a longitudinal axis of the portal and a seal. The seal includes internal surfaces having a passage for reception and passage of a surgical object in substantial sealed relation therewith and defines a seal axis. The seal includes a foam segment comprising a foam material and a fabric segment comprising a fabric material and being mounted relative to the foam segment. The fabric segment may be disposed adjacent one of the proximal and distal surfaces of the foam segment. The fabric segment may include a fabric layer which is in juxtaposed relation with the one of the proximal and distal surfaces of the foam segment. The fabric layer may include slots therethrough to facilitate passage of the surgical object through the seal. The slots may be arranged to extend radially outwardly relative to the seal axis.

Abstract: A suture tester for evaluating fray resistance of surgical sutures. The suture tester comprises a reciprocating drive member, first, second, third and fourth pulleys, and a tensioning element. The pulleys each have a suture contact surface, which define a single plane. The third pulley is rotatable about this single plane. The first, second and third pulleys are all movable on the single plane. A suture is mounted in the suture tester such that one end is attached to the reciprocating drive member, it then passes to the first pulley, to the third pulley, to the second pulley and to the fourth pulley, before attaching to the tensioning element at the other end of the suture. The third pulley is then rotated and locked into place to form the desired number of suture wraps. The suture tester is started and causes the suture to rub against itself until it fails.
