Abstract
The present disclosure is directed to ablative devices comprising biocompatible materials in the form of a mesh to provide porosity to allow for the conveyance of conductive fluid to target tissue to be ablated. The mesh also increases the durability of the biocompatible material, reducing the amount of biocompatible material needed for both reusable devices and disposable ablative devices, such as ablative forceps and ablative probes.
Claims12
Forceps comprising:
- first and second pincers, each pincer having an intermediate body portion, a proximal portion extending from the body portion, and a distal portion extending from the body portion;
- at least one lumen extending to the distal portion of the first pincer, second pincer, or both the first pincer and second pincer;
- a first electrical conductor operably linked to a source of electrical energy and the proximal end of the first pincer;
- a second electrical conductor operably linked to a ground and the proximal end of the second pincer;
- and
- conductive tips operably connected to the distal portion of each pincer, each conductive tip comprising a mesh of biocompatible material, wherein the mesh consists of 2, 3, or 5 fused layers, each conductive tip in fluid communication with the at least one lumen and configured to allow passage of a fluid from the at least one lumen through the mesh to the exterior of the conductive tips;
- the forceps configured to deliver electrical energy for ablation to the conductive tips of the distal portions of the first and second pincer when compressed towards one another.
