TL;DR: In this paper, a coil stent constructed from a nitinol alloy having the ends thereof shaped to interact with a placement device specifically designed to hold the stent in a reduced diameter while it is being maniuplated to its desired position in the patient's body.
Abstract: Disclosed is a coil stent constructed from a nitinol alloy having the ends thereof shaped to interact with a placement device specifically designed to hold the stent in a reduced diameter while it is being maniuplated to its desired position in the patient's body. The placement device is a hollow tube which has holes in it surface allowing placement of the ends of the stent therethrough so that they can be held in place inside the interior of the placement device by a mandril which is threaded through the center of the placement device. The combination of the features of the shapes on the end of the stent, the holes in the placement device and the mandril which passes through the placement device and the shapes on the end of the stent allow the interventional radiologist to accurately and rapidly place the stent in its desired position before it changes shape to its final pre-set configuration.

TL;DR: In this paper, a minimally invasive intravascular medical device for providing a radiation treatment in a body passageway such as a coronary vessel of the vascular system is presented, which includes a flexible elongated member having distal and proximal portions.
Abstract: A minimally invasive intravascular medical device for providing a radiation treatment in a body passageway such as a coronary vessel of the vascular system. The device includes a flexible elongated member having distal and proximal portions. The distal portion is percutaneously insertable into a vessel and includes a distal end that is directable through the vessel to the treatment site. A radiation source is attached about the distal portion for delivering a radiation treatment to the walls a vessel having a stent positioned thereagainst. The distal portion of the elongated member includes a wire coil positioned about the tapered distal end of a mandril wire. The combination of the wire coil and the tapered distal end of the mandril wire provides variable flexibility to the distal portion of the device. The distal portion also has a predetermined curvature for directing the distal end of the device through the vessel. A safety wire is also extendable through the passageway of the wire coil to provide further flexibility to the distal portion. The radiation source is fixedly positioned about either the tapered distal end of the mandril wire or the safety wire in the passageway of the wire coil. An annular recess is included about the tapered distal end of the mandril wire to fixedly position a source of radioactive material therein.

TL;DR: In this article, a length of small intestine submucosa tissue is wrapped around a mandril having legs connecting a bight and diverging from that point, and the diverging angle of the legs (22, 24) of the mandril is selected to compensate for various lengths of the edges.
Abstract: A method of forming a reconstructive structure for cartilaginous elements, and the product produced by that method is disclosed. A length of small intestine submucosa tissue (10) is wrapped around a mandril (20) having legs (22 and 24) connected a bight (26) and diverging from that point. The diverging angle of the legs (22, 24) of the mandril is selected to compensate for various lengths of the edges (12, 14) and to produce flat or planar layers. The multilayered composite produced is used in the repair or replacement of cartilaginous tissues.

19 Jul 1984TL;DR: In this article, a catheter wire guide with an axially movable mandril with a tapered tip is described, which is coated with a lubricating material, such as Teflon, for facilitating the smooth movement of the mandril within the wire guide.
Abstract: 57 A catheter wire guide having an axially movable mandril with a tapered tip for permitting the flexibility of the distal tip of the wire guide to be varied. The mandril is coated with a lubricating material, such as Teflon, for facilitating the smooth movement of the mandril within the wire guide.

TL;DR: In this article, a system for treating stenosis or blockage in a bodily fluid passageway is described, which includes a catheter (10), a controller (40), a monitoring circuit (70) for monitoring the phase of the RF energy along the output lines, an impedance matching circuit (60) for adjusting the output impedance of the generator (50) so that it equals that of the load, e.g., the patient.
Abstract: A system, and method for treating a stenosis or blockage in a bodily fluid passageway is described which includes a catheter (10), a controller (40) for generating RF energy along a pair of output lines (40), a monitoring circuit (70) for monitoring the phase of the RF energy along the output lines, an impedance matching circuit (60) for adjusting the output impedance of the generator (50) so that it equals that of the load, e.g., the patient. The catheter includes a catheter body which is inserted into the bodily passageway, and operatively connected to the controller. A lumen (16) in the catheter body defines an opening. A stainless steel, metallic-plated mandril (18) is disposed within the lumen so that a terminal end thereof extends through the opening, and into the bodily passageway. An internal electrode (26) is joined to the terminal end of the mandril.
