Abstract: The present invention is an ablation device having a flexible and resilient shaft that can provide fluid to the site of ablation from a plurality of different fluid sources.

Abstract: The invention relates to a tissue ablation system including an ablation device having a deployable applicator, preferably, with a non-spherical head configured to be delivered to a tissue cavity and ablate marginal tissue surrounding the tissue cavity. The deployable applicator head is configured to be delivered to a tissue cavity while in a collapsed configuration and ablate marginal tissue surrounding the tissue cavity while in an expanded configuration.

Abstract: The present invention is an ablation device having a screen sphere configuration for the ablation of marginal tissue surrounding a tissue cavity. The device includes a probe having a nonconductive elongated shaft including at least one lumen therethrough and a nonconductive distal portion extending from the shaft. The nonconductive distal portion includes a plurality distal ports and a plurality of proximal ports in communication with the at least one lumen of the shaft. The device further includes an electrode array including a plurality of independent conductive wires extending through the lumen and positioned along an external surface of the nonconductive distal portion, each of the plurality of wires passes through at least an associated one of the proximal ports and through at least a corresponding one of the distal ports.

Abstract: An elastomer that includes the reaction product of an A-side that includes an isocyanate and a B-side that includes a blown vegetable oil, a cross-linking agent including a multi-functional alcohol, and a catalyst.

Abstract: Polyurethane curable systems that contain an aminated glycerol as a catalyst to enhance the cure rate of the systems. The systems are based on polyoxyalkylene polyols that can be either polyether or polyester polyols. In addition, the polyols can be those that are provided by natural oils, such as soybean, corn oils, and the like. The polyols are typically dihydroxy functional, but can be tri- or quadra-functional or more. The systems are comprised of the reaction of such polyols with organic isocyanates, including the use of chain extenders from diols, or a mixture of triols and diols, such that the overall functionality of the mixture is generally less than 2.3. The organic isocyanates are also at least di-functional and can be tri- or greater functional, with regard to the isocyanate groups used on such molecules. The polyurethane systems can be, for example, elastomers, sealants, adhesives, or foamable systems.

Abstract: The present invention includes a method for making a bio-based carpet material by providing tufts, a backing, a pre-coat, and a backing material wherein the pre-coat includes the reaction product of a pre-coat A-side having a pre-coat isocyanate and a pre-coat B-side and the backing material includes the reaction product of a backing material A-side having an isocyanate and a backing material B-side. The pre-coat B-side and the backing material B-side may include a polyol derived from petroleum; a vegetable oil, cross-linker, and a catalyst; or a transesterified polyol.

Abstract: An elastomer that includes the reaction product of an A-side that includes an isocyanate and a B-side that includes a blown vegetable oil, a cross-linking agent including a multi-functional alcohol, and a catalyst.

Abstract: A method for manufacturing a carpet material that typically includes applying a coating to a substrate where the coating includes the reaction product of a B-side that includes an esterified vegetable oil-based polyol and a catalyst and an A-side that includes an isocyanate and the reaction product of a B-side that includes a vegetable oil-based polyol and a catalyst and an A-side that includes an isocyanate. The polyols may optionally be blown, oxylated, and/or neutralized.

Abstract: A building material composite that includes a building substrate at least partially lined with a urethane material. The urethane material of the present invention is typically the reaction product of an A-side that includes an isocyanate and a B-side that typically includes: a blown vegetable oil, a cross-linking agent, and a catalyst; a blown vegetable oil and a multifunctional alcohol; or an esterified polyol and a catalyst where the esterified polyol is typically the reaction product of a first polyol and a blown vegetable oil.

Abstract: The present invention includes a method for making a bio-based carpet material by providing tufts, a backing, a pre-coat, and a backing material wherein the pre-coat includes the reaction product of a pre-coat A-side having a pre-coat isocyanate and a pre-coat B-side and the backing material includes the reaction product of a backing material A-side having a backing material B-side. The pre-coat B-side and the backing material B-side may include a petroleum based polyol; a vegetable oil, cross-linker, and a catylst; or a transesterified poylol.
