Abstract: The current invention involves compositions methods and apparatus for killing various soft-bodied animals of interest (more specifically, Coqui frogs and Coqui frog eggs are targeted) with a low pH adjusted pesticide. The method and apparatus involves contacting the soft-bodied animal of interest with the low pH adjusted pesticide, wherein the pesticide is a propionic acid composition, a citric acid composition, an Acidic Calcium Sulfate (ACS) composition, or combination thereof. The preferred pesticide composition has a working concentration that is less than about 15% (w/v), and a pH less than about pH 2.5, which has a lethal effect on Coqui frogs, but is less phytotoxic than higher concentration pesticides. The method and apparatus includes spraying any of the pH adjusted pesticides thoroughly an area inhabited by the soft-bodied animals of interest, which includes the under brush, under bushes, and typically any hiding places. An apparatus for spraying potted plants is disclosed.

Abstract: The present invention relates to an apparatus and method for utilizing energy, such as radio frequency (RF) energy, to treat defined areas of tissue and more particularly to ablate tumors with RF energy through the use of a needle having a spreading array of individually traversing conductive tines which are independently positioned and activated.

Abstract: An intravascular catheter having a shaft, at least a portion of which includes a braid reinforcement with an axial wire or fiber disposed between the helical members that form the braid. The axial member prevents the elongation of the shaft of the catheter thereby maintaining one-to-one correspondence in axial manipulation of the catheter, even when the shaft is placed in tension. By positioning the axial member between the helical members, the axial member does not create a protrusion and does not become fixed to any adjacent polymer layer. Thus, the axial member limits axial strain of the catheter, without creating the undesirable effects of friction caused by an axial protrusion and without creating the undesirable effects of limited flexure caused by an adjacent polymer layer becoming fixed to the axial member.

Abstract: An intravascular catheter having a shaft, at least a portion of which includes a braid reinforcement with a plurality of axial members disposed between the helical members that form the braid. The axial members provide a number of advantages including: maintaining one-to-one correspondence in axial manipulation; maintaining uniform flexibility in several planes of flexure; reducing the likelihood of causing a curling effect; increasing the strength of connections between shaft segments; uniformly increasing stiffness of the catheter; and increasing the burst strength of the catheter. By positioning the axial members between the helical members, the axial members do not create a protrusion and do not become fixed to any adjacent polymer layer. Thus, the benefits of axial members are retained, without creating the undesirable effects of friction caused by an axial protrusion and without creating the undesirable effects of limited flexure caused by an adjacent polymer layer becoming fixed to the axial member.
