  • 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.

  • Publication number: 20160235909
    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.

The device has at least two syringes that contain the inter-reactive components of the multi-part biomedical composition. At least the barrel of the first syringe has a first retention compartment having a cross-sectional area dimension that is larger than the cross-sectional area of a second retention compartment. The first piston has a cross-sectional dimension that matches the inside cross-sectional dimension of the small dimensioned retention compartment, while a ring-shaped gasket is located within the large dimensioned retention compartment and has an outside cross-sectional dimension that matches an interior dimension of the large dimension retention compartment.
