A surgical drain for operative and post operative usage providing a core comprising a pliant drainage conduit having through wall passages throughout its lenth from its distal end to a point inset from its proximal end and a co-extensive pliant irrigation conduit open at its ends, a padding layer of soft, non-friable absorbent material surrounding said core from its distal end to a point opposite the proximal end passages of the drainage conduit, a soft rubber or like sheathing surrounding the padding layer from end-to-end and having through wall passages throughout its length from its distal end to a point opposite the proximal end passages of the drainage conduit, and a securing suture extending through the proximal ends of the padding layer and sheath and encircling the core to retain the parts assembled. Fittings are provided at the proximal ends of the respective conduits adapting them respectively for connection to a suction line and to an irrigation line and the fitting of the irrigation conduit includes a normally closed plug valve selectively opened to provide irrigation when needed.
A surgical drain is disclosed in the form of a drainage catheter about the inner or distal end of which a nylon net is wrapped and retained in position loosely by a plurality of ties with the net and catheter being encased in a thin rubber sheath in a loose manner so that air can flow into the sheath when the outer or proximal end of the catheter is connected to suction; an additional feature resides in an irrigation catheter extending through and along the length of the sheath for providing an irrigation discharge outwardly of the distal end of the sheath for discharging internally of the sheath for internally flushing the sheath for discharge via the suction catheter.
A balloon-type Tissue expander device is provided that has a main balloon portion for stretching tissue when implanted under the skin. The expander balloon includes an inflation conduit and a separate drain tube connected thereto serving to drain fluid accumulating around the balloon away from the implant site. Also an irrigation tube can be included with the drain tube. Finally a pressure transducer is provided to measure pressure within the balloon.
An improved surgical drain of the Abramson type having a triple lumen catheter with a drainage lumen, an irrigation lumen, and an air ventilation lumen. The improved drain is interfitted with a connector providing a suction port for the drainage lumen, an irrigation port for the irrigation lumen, and an air intake port for the air ventilation lumen. Closure plugs for each port may also be provided. The improved drain further includes a suture means for securing the drain in place and stabilizing it and a softened distal end portion to reduce tissue necrosis upon insertion of the drain into the patient's body.
The devices and methods shown provide for the minimization of extravasation during arthroscopic surgery. The extravasation minimization device allows a surgeon to drain excess fluids from the soft tissue surrounding the surgical field while also providing a stable surgical portal for arthroscopic surgical instruments.
6605068 - Gravity drainage cord - Owned by Med Europe S.r.l. (S. Pietro In Casale,IT) Righetti; Roberto (S. Pietro In Casale,IT)
A gravity drainage cord formed by braiding a plurality of strands of silk of the type used for surgical sutures, and fitted loosely, in the median region, in a tubular sheath made of a material such as silicone which is adapted to facilitate sliding with respect to tissue, increases biocompatibility and allows optional coupling to mechanical aspiration units.
