Description

TissuePatch™ is a synthetic, self-adhesive surgical sealant for the avoidance and resolution of leaks in surgery. It is particularly effective in adjunctive closure of lung tissue to minimise air leaks during thoracic surgery procedures.

TissuePatch™ is fully synthetic, containing no human, bovine or porcine material.

It is multi-layered, incorporating structural and adhesive absorbable components.

The active component within TissuePatch™ is Tissuemed’s proprietary TissueBond™ bioadhesive technology. This bonds the film to proteins on the tissue surface within a minute, providing immediate support and an effective airtight closure during the natural healing process.

TissuePatch™ requires no advance preparation and can be applied straight from the pack.

TissuePatch™ enables the surgeon to visualise underlying tissue. As a very fine, transparent film it becomes almost invisible once adherent to lung surface, except for the indicative logo.

At only 40 microns thick, TissuePatch™ delivers an effective therapeutic solution for only a tiny amount of foreign material.

It is available in a range of sizes and shapes and can be cut to shape to suit clinical requirements.

Purpose

TissuePatch™ is indicated to seal and reinforce against air leaks during surgical repair of the lungs in Thoracic Surgery.

It can be used in open and thoracoscopic procedures, for which a dedicated delivery and application system is available.

By helping surgeons to achieve an airtight closure the product helps in the avoidance of post-operative complications associated with leaks. This means it can contribute to shorter patient stays and reduced healthcare costs.

Simply Open and Apply

How to Use it

Three simple steps to achieving a watertight result (open surgery)

Step 1: Open and dispense

Carefully peel apart inner pouch in sterile field. Gently remove the patch with forceps, remembering that it is at its most fragile in its pre-application state. No preparation is necessary and the patch is now ready to use. Ensure the logo is facing upwards and is readable throughout placement.

Step 2: Place

Target tissue should be gently swabbed, but does not need to be absolutely dry. Place the patch gently on the tissue. Aim for a minimum 1cm margin from suture line to the edge of the patch. If required, limited patch repositioning is possible if performed immediately at this stage.

Step 3: Adhere to Target Tissue

Hold a damp swab over the patch, “encouraging contact” with tissue surface for 60 seconds. If reassurance is needed, repeat the exercise but do not reposition or move the same patch. Overlapping patch edges to achieve coverage is possible. Note however that patch-over-patch adhesion is less strong than patch over tissue.

 

Thoracoscopic (VATS) application:

TissuePatch can be inserted into the thoracic cavity using dedicated instrumentation. The patch can be manipulated into position over target staple line, when small swabs can be employed to gently locate and affix it to the tissue surface. As with all patch applications, bonding to tissue surface is not instant, so may require gentle pressure and a steady “dabbing” action to achieve fixation. Images show use of swab and end result with TissuePatch firmly adherent and covering all potential air leak sites.

 Hints and Tips

1. Can it be cut to shape or size? Yes. To minimise handling, it is suggested that patch be cut in the sleeve first before removing.
2. Does it need to be wet before application? No. Wetting prior to use is not strictly required. However, hydration is not contraindicated and can enhance handling characteristics.
3. Should adherence be tested before closure? Usually patch adherence is visually apparent, but if confirmation is required do not use sharp instruments as these may risk “puncturing” the patch.
