A medical device including a first layer having an opening formed therein. A second layer is positioned with respect to the first layer to form a pocket therebetween. A support member is at least partially located in the pocket and reconfigurable for removal of the support member from the pocket via the opening. An affixation element located in the pocket between the support member and the second layer, and secured to the second layer. A method of implanting a medical device is also included.

Medical device having removable deployment device and affixation element

A medical device including a mesh prosthesis having a first layer having an opening a second layer secured to the first layer and forming a pocket therebetween. A deployment device is positioned in the pocket and arranged to resiliently exert a deployment force on the mesh prosthesis to urge the mesh prosthesis into a deployment shape. The deployment device has a first shape when deployed that has at least one dimension larger than that of the opening to frustrate removal of the deployment device therethrough. Upon application of a suitable pulling force the deployment device is reconfigurable into a second shape that permits the deployment device to be removed from the pocket through the opening upon application of the suitable pulling force. A method of using a medical device is also included.

Removable deployment device, system, and method for implantable prostheses

A material including a plurality of fatty acid chains cross-linked together and a silver fatty acid salt formed with the fatty acid chains within the material. Methods for forming a material are also included. The silver-containing materials can be utilized alone or in combination with a medical device for the release and local delivery of one or more anti-infective agents.

Anti-infective antimicrobial-containing biomaterials

A hernia patch supporting tissue in-growth conforms to a tissue wall upon surgical installation and fixation within a patient. The hernia patch can include a base and positioning straps. The base is formed of two layers that are affixed to each other around the perimeter of the patch, for example by stitching. A stabilizing washer is provided between the two layers, and the stitch is provided peripherally around the stabilizing washer, keeping the washer free-floating between the layers. The base, positioning straps, and stabilizing washer are formed of a structure that does not separate the layers of the implant or form a space in the form of a pocket, and promotes more uniform and confluent tissue incorporation or in-growth after implantation. The hernia patch may further include a hydrolysable bioabsorbable cross-linked coating of a fatty acid based material, such as an omega-3 fatty acid based material.

Hernia patch

A deployment device for a flexible implant includes a housing and one or two chambers formed therein. When two chambers are included, the housing can have two elongate openings formed in its outer sides, each providing side access to one of the chambers, and the flexible implant can be rolled into a double-rolled configuration and placed in the chambers of the deployment device in such a way that a middle portion of the flexible implant is external to the housing. When the flexible implant is rolled and loaded in the deployment device, the flexible implant can extend out through open end(s) of the chamber(s) or can be encapsulated within the chamber(s). The flexible implant can be provided separate from the deployment device. The flexible implant can include a flexible base sheet including a body portion and a tab. A flexible separable layer can be removably disposed on the body portion.

Rolled flexible implants and device for deployment thereof

A barrier device is formed of a barrier component that can exhibit anti-inflammatory properties, non-inflammatory properties, and/or adhesion-limiting properties, as well as generate a modulated healing effect on injured tissue. The barrier component can be a non-polymeric cross-linked gel derived at least in part from a fatty acid compound, and may include a therapeutic agent. The barrier device can have anchoring locations to provide an area on the barrier device to interface with an anchoring mechanism. The anchoring locations can include openings and/or anchor elements. The barrier device can also include truss structures that provide additional strength to the barrier component. The barrier device is implantable in a patient for short term or long term applications, and can include controlled release of the therapeutic agent.

Implantable barrier device

An implantable prosthesis can have a three-dimensional shape that is invertible, so as to assume either a right configuration or a left configuration, which can be substantially mirror images of each other, so as to eliminate the need for separately manufacturing a left prosthesis and a right prosthesis. An implantable prosthesis can be preformed to independently assume a contoured three-dimensional shape that more adequately fits the extraperitoneal laparoscopic inguinal space, while simultaneously maintaining a relatively large area for fixation of the prostheses (e.g., through suturing or integration with the surrounding tissue). An implantable prosthesis can have a three-dimensional contoured shape that is formed from a single piece of continuous material, such as a mesh, and can possess substantially uniform rigidity. An implantable prosthesis may be trimmed, cut, or altered at an outer perimeter with no detrimental effect on its ability to independently maintain a predetermined three-dimensional contoured shape.

Implantable prosthesis

An implantable prosthesis device and system for insertion, deployment, and fixation of a hernia prosthesis. The system includes two or more deployment rods removably affixed to the prosthesis. Each rod extends across a majority of a width of the prosthesis and beyond one end of the width of the prosthesis. The rods are arranged generally parallel to one another when in a rolled configuration. The rods are separate, physically noncontiguous wire rods that are not operably coupled to one another. The rods provide structural reinforcement and increased rigidity across the width of the implantable hernia prosthesis while maintaining the ability of the prosthesis to experience bends in its length. In this way, the rods allow a user to separately manipulate discrete portions of the prosthesis while to maintaining the ability of the prosthesis to be rolled up and inserted into the body of a patient through, e.g., a trocar.

Deployment rods for use with implantable hernia prostheses

A barrier layer device is formed of an underlying biocompatible structure having a barrier layer coating that can exhibit anti-inflammatory properties, non-inflammatory properties, and/or adhesion-limiting properties, as well as generate a modulated healing effect on injured tissue. As implemented herein, the barrier layer is a non-polymeric cross-linked gel derived at least in part from a fatty acid compound, and may include a therapeutic agent. The underlying structure can be in the form of a surgical mesh. The barrier device is further provided with reinforced sections or portions to aid with the fastening of the barrier device for implantation purposes and prohibits or substantially reduces the occurrence of excessive stretching and tearing. The barrier device is implantable in a patient for short term or long term applications, and can include controlled release of the therapeutic agent.

Barrier layer with underlying medical device and one or more reinforcing support structures

A prosthesis includes an enclosure. A flexible support structure is situated at least partially within the enclosure and is removable therefrom. The flexible support structure occupies a total circumferential area and has a stiffness that is sufficient to allow the prosthesis to assume a deployed (e.g., generally planar) configuration. A tab is adjoined with the flexible support structure and extends external to the enclosure. Pulling the tab directionally away from the prosthesis causes a reconfiguration of the flexible support structure sufficient to enable the flexible support structure to pass through an opening in the prosthesis having a total circumferential area that is less than the total circumferential area occupied by the flexible support structure when the prosthesis is in the deployed (e.g., generally planar) configuration, enabling removal of the flexible support structure from the enclosure.

A surgical mesh is formed of a biocompatible mesh structure with a coating that provides anti-inflammatory, non-inflammatory, and anti-adhesion functionality for a implantation in a patient. The coating is generally formed of a fish oil, can include vitamin E, and may be at least partially cured. In addition, the coating can include a therapeutic agent component, such as a drug or other therapeutic agent.
