Methods are provided for making freeze dried hydrogel and structures therefrom that may be introduced into a patient's body for medical applications. Precursor components are combined to initiate crosslinking. The combined precursor components are placed in a chilled tray, and allowed to crosslink to a desired level of complete crosslinking before and/or after being placed onto the tray. The partially crosslinked hydrogel is frozen and freeze dried. After freeze drying, the hydrogel is conditioned to substantially complete crosslinking, and formed into one or more structures, e.g., plugs, hemostatic, or other medical devices. For example, the hydrogel may be cut, machined, rolled, folded, compressed, and/or cored into that may be loaded into delivery devices that may be introduced into a body to implant or otherwise deliver the structures into the body, e.g., to seal a puncture or other passage through tissue.

Superabsorbent, freeze dried hydrogels for medical applications

A medical device for wound closure, e.g., repairing perforations and tissue wall defects. The medical device has a barbed elongate body and an outer member. The medical device may further include a foam structure. The medical device may also include an inner member which may be a tissue scaffold. A method for closing tissue is also disclosed.

Medical device for wound closure and method of use

A wound closure device for repairing perforations and tissue wall defects is disclosed herein. The wound closure device has a barbed elongate body and a plug member. The wound closure device may further include a foam structure. The wound closure device may also include an inner member which may be a tissue scaffold. A method for closing tissue is also disclosed.

The present disclosure includes systems and a method for in situ application of a surgical patch during minimally invasive surgery. The method includes the steps of inserting a surgical patch into a bag; transferring a polymeric bag containing a hemostatic patch into a body cavity; removing the surgical patch from the polymeric bag while the polymeric bag is within the body cavity; and applying the surgical patch to a tissue within the body cavity.

System and method of laparoscopic use of hemostatic patch

A surgical device includes a handle, an elongated tube extending distally from the handle, and a suction tip at a distal end portion of the elongated tube. The suction tip has a cavity formed therein. A cutting blade is positioned at least partially within the cavity and rotatable across the cavity to sever tissue, the cavity dimensioned to receive the severed tissue for removal from a patient's body.

Vacuum assisted surgical dissection tools

A tissue buttress is provided on at least a first and second jaw of a surgical stapling apparatus. The tissue buttress comprises an electrophilic component and a nucleophilic component. At least a portion of the tissue buttress may be disposed within either or both of the staple pockets and staple forming pockets, securing the tissue buttress to at least one of the staple jaws.

Buttress composition

The present disclosure relates to collagen-containing implants including a porous substrate having a first hydrogel precursor and a second hydrogel precursor applied thereto in a manner such that the first hydrogel precursor and second hydrogel precursor do not react with each other until the implant is placed at the site of implantation and exposed to the physiological fluids of a patient.

Hemostatic implant

The present disclosure relates to a hydrogel composition and methods of using the same. The hydrogel composition may include precursors that react with each other upon contact as well as precursors that react upon contact with an initiator. In embodiments, the resulting hydrogels may have varying levels of crosslinking with both denser and less dense regions.

Hydrogel implants with varying degrees of crosslinking

A surgical device comprising a handle, an elongated tube extending distally from the handle, and a suction tip at a distal end portion of the elongated tube. The suction tip has a cavity formed therein. A cutting blade is positioned at least partially within the cavity and rotatable across the cavity to sever tissue, the cavity dimensioned to receive the severed tissue for removal from a patient's body.
