  • Publication number: 20210322624
    Abstract: Novel surgical sutures and novel medical devices made from novel semi-crystalline, glycolide-rich A-B-A triblock copolymers of glycolide and lactide, wherein said B-segment is a fully amorphous random copolymer of glycolide and lactide, for long term medical applications are disclosed. The novel polymer compositions are useful for long term absorbable surgical sutures, meshes and other medical devices, especially for patients with compromised healing. The novel sutures have improved properties and improved breaking strength retention, while still substantially absorbing within about a 120-day period post-implantation.

    Abstract: Devices and methods for placing an adjunct at a tissue treatment site prior to delivering staples through the tissue and adjunct are provided. In one embodiment, a flowable adjunct precursor can be deposited on the surface of the tissue at the tissue treatment site. The flowable adjunct precursor can be configured to solidify after deposition to form an adjunct. In another embodiment, an adjunct delivery device can include a non-stapling end effector configured to deliver an adjunct to a tissue treatment site. In either case, staples can be delivered through the adjunct and tissue after placement of the adjunct at the tissue treatment site.

  • Patent number: 10226569
    Abstract: Exoskeletal devices or sleeves that can be used with the delivery tube of an applicator device to help dispense fluids, typically flowable biocompatible materials such as hemostatic agents, adhesives, or sealants, onto specific sites in the human body for a medical reason are disclosed. The exoskeletal devices or sleeves are rigid, pre-shaped, and snappably or slidably affixed to the delivery tube. The exoskeletal devices or sleeves do not come into contact with the flowable biocompatible fluid being dispensed, and they can be placed at any position along the delivery tube to address different application situations. Once the exoskeletal device or sleeve is in place, it can optionally be locked onto the delivery tube to prevent further sliding under stresses when pushed against tissue. Multiple exoskeletal devices or sleeves can also be used to achieve more complicated shapes for hard-to-reach anatomical sites.

  • Publication number: 20180333247
    Abstract: A surgical fastener for anchoring medical devices to tissue includes a first leg having a proximal end, a distal end, a first rib projecting from an outer wall of the first leg and extending between the proximal and distal ends of the first leg, and a first insertion tip at the distal end of the first leg. The surgical fastener includes a second leg having a proximal end, a distal end, a second rib projecting from an outer wall of the second leg and extending between the proximal and distal ends of the second leg, and a second insertion tip at the distal end of the second leg. A bridge connects the proximal ends of the first and second legs for forming a closed end of the surgical fastener. The first and second legs are curved between the bridge and the first and second insertion tips at the distal ends of the respective first and second legs, and the first and second ribs have curves that mirror the curvature of the respective first and second legs.

  • Patent number: 9848871
    Abstract: Adjunct materials and methods of using adjunct material to reinforce a staple line are provided. In general, an adjunct material can be used to maintain a seal in tissue and can prevent stapled tissue from tearing. In some embodiments, a surgical stapler can include a jaw having an adjunct material associated with the jaw. The adjunct material can be attached to tissue via staples deployed by the stapler. In some embodiments, an adjunct material can be a woven material having a single layer or multiple layers, and each layer can have different mechanical properties. In other embodiments, an adjunct material can have a single layer or multiple layers of nonwoven material, such as suture compressed into a three dimensional structure.

  • Patent number: 9801630
    Abstract: Adjunct material and methods of using adjunct material to reinforce tissue in proximity to a staple line are provided herein. In general, the adjunct material can be used to maintain a seal in tissue, such as lung tissue, and prevent stapled tissue from tearing. This adjunct material can be coupled to a jaw of a surgical stapler, and can be deployed into tissue along with the staples. In some embodiments, the adjunct material can comprise an outer material encompassing an inner, hydrophilic swellable material. The outer material can be selectively dissolvable and/or absorbable. When the outer material is punctured by staples or otherwise penetrated, moisture is passed to the inner material which then swells and expands to transition to a predetermined shape to seal the tissue and prevent leaks from forming in the tissue. Portions of the inner material around the staple line can transition to a large radius.
