  • Patent number: 11432810
    Abstract: A retractor system may provide access to a surgical site along an access pathway surrounded by tissue. In some embodiments, the retractor system may include three arms and four retractor blades, each having a tissue engagement surface. The second arm may translate along a first retraction direction relative to the first arm. The first retractor blade may be securable to the first arm and the second retractor blade may be securable to the second arm. The third arm may have a connection feature that may be removably securable to a connection interface of the second arm. The third retractor blade may be securable to the third arm and the fourth retractor blade may be securable to a rack between the first and second arms. The third and fourth retractor blades may have cross-sectional shapes oriented generally parallel to the first retraction direction.

  • Publication number: 20170367745
    Abstract: This invention relates to a system and a method for affixing soft tissue to bones. The system for fixing soft tissue within a bone tunnel comprising a first fixation member having a proximal end and a distal end and a bore extending from said proximal end to said distal end, said first fixation member is adapted for insertion against a first portion of a soft tissue positioned within a bone tunnel, a second portion of said soft tissue emerging from said bone tunnel; a second fixation member adapted to engage said bore of said first fixation member, having means for restraining disengagement therewith and a proximal end; and a third fixation member adapted to engage said second portion of said soft tissue, having means for coupling onto said proximal end of said second fixation member and restraining disengagement therewith.

  • Publication number: 20070219478
    Abstract: An elongate flexible strap is adapted to be wrapped about a wearer's leg and pelvic region. The strap applies a torque to the leg, rotating the leg into a desired degree of external rotation. In a leg having an improperly aligned patella, it is believed that the external rotation improves lower extremity mechanics by aligning the patella within the trochlear groove.

  • Publication number: 20050240135
    Abstract: An osteoarthritis brace having relatively large semi-rigid cuffs for abutting the wearer's thigh and calf. In one embodiment, the semi-rigid cuffs are secured to rigid cuffs of the brace only on one side and in substantially a center of the rigid cuffs. The semi-rigid cuffs bear reaction forces created by a medial/lateral force applied to the wearer's knee by a hinge of the brace. The semi-rigid cuffs provide flesh containment, distribute loads over a large portion of the wearer's flesh, eliminate pinch points and provide enhanced fitting capabilities.

  • Publication number: 20050010147
    Abstract: Abstract of the Disclosure A shoulder sling is provided for the treatment of, for example, gleno-humeral dislocations and subluxations, capsular shifts, postoperative rotator cuff repair, postoperative Bankart procedures and soft tissue strains and repairs. The sling includes a support pillow abuts the wearer's torso, and a pouch that receives the wearer's arm. A plurality of straps suspend the pillow and pouch from the wearer's non-treatment shoulder. One of the straps prevents the pillow from shifting relative to the user, thus securely maintaining the wearer's arm at desired angles of abduction and external rotation. The pillow further includes an attached exercise grip and an indicator line that aids a physician in properly fitting the sling to the wearer.
