Abstract: A method of filtering debris from the fluid back splash off a structure that is being pressure washed. The fluid falling onto a filter screen and passing through the filter screen before entering the ground. The filter screen made of glass threads woven into a filament. The filament is woven to form a sheet having a width greater than three feet and a length greater than three feet. The sheet has peripheral end edges with a border of flexible material disposed therearound. The border has a top side and a bottom side. A plurality of pile-type fastener means are attached along the top side and the bottom side of the border and symmetrically spaced thereabout. The plurality of pile-type fastener means couple with corresponding fastener means when the sheet is rolled.

Abstract: A generally planar support member is detachably securable to a medical table and has an upper surface for receiving the arm of a patient thereon. Brace means depending from the support member abut the table to stabilize the support member in a generally horizontal position. Means are also provided for draining fluids from the upper surface.

Abstract: An elongate stylet slidably disposed within a thermoelectric insulative sheath has a forward-projecting surgically incisive tip for entry of the sheath into the peritoneal cavity. After the stylet is withdrawn, an elongate shaft having hook-shaped electrical resistance element extending forwardly therefrom is slidably inserted through the sheath and the resistance element engaged with a Fallopian tube. Subsequently, the sheath is moved forwardly to encase the resistance element in the doubled section of Fallopian tube engaged therewith. An electrical energy impulse from a controlled source thereof energizes the resistance element for concurrent electroresection and electrocoagulation of the Fallopian tube in an environment shielded from adjacent organs.

Abstract: A pair of elongate flexible curvilinear shafts are adapted at one end thereof to be secured to a surgical operating table. Detachably securable to the free end of each shaft is a pair of mutually arcuate straps which receive and hold a foot to support a patient's legs during certain surgical procedures. Manually operative detent means carried by the free end of the shaft and operatively associated with the straps provide for selective restraint or release of the foot.
