  • Anti-jamming and macerating thrombectomy apparatuses and methods
    Patent number: 10028759
    Abstract: Mechanical thrombectomy apparatuses that may be configured to prevent or reduce jamming (e.g., “anti-jamming” thrombectomy devices), grab clot, and/or macerate the thrombus, e.g., clot, being removed. These mechanical thrombectomy apparatuses may include a tractor comprising a flexible tube of material that inverts as it rolls over itself while being drawn into a catheter in a conveyor-like motion. In particular, described herein are mechanical thrombectomy apparatuses having tractors selectably extendable projections that may aid in grabbing and/or macerating a clot. Also described herein are seesawing tractors for mechanical thrombectomy apparatuses.

  • Corner-lock stitch patterns
    Patent number: 9925030
    Abstract: Stitching patterns overlap to produce a corner-locked stitch pattern. The corner-locked stitch pattern includes one or more thread interlace points, and one or more overlays of threads from overlapping patterns. A network of corner-lock stitch patterns produces a mesh, which may be embroidered into a substrate, such as a medical textile or biotextile. Corner-lock stitch patterns resist puncture-induced and tension-induced deformation of mesh pores between corner-locked stitch patterns, and may be used to modulate compliance and enhance strength properties of a substrate into which they are sewn.

  • HERNIA REPAIR GRAFTS HAVING ANTI-ADHESION BARRIERS
    Publication number: 20180071071
    Abstract: Materials for soft tissue repair, and in particular, material for hernia repair. These materials may be configured as an implant, such as a graft, that may be implanted into a patient in need thereof, such as a patient having a hernia or undergoing a hernia repair surgical procedure. These grafts may include a first layer comprising a substrate (e.g., mesh) and a second layer comprising a sheet of anti-adhesive material. The layers may be attached with a plurality of relatively small attachment sites that are separated by regions in which the two layers are not attached, to provide a highly compliant graft.
