A medical simulation apparatus may include a housing, a vessel simulating tube carried by the housing, a liquid reservoir carried by the housing, a pump carried by the housing for circulating the liquid from the liquid reservoir through the vessel simulating tube, and an access port in fluid connection with the vessel simulating tube for receiving an instrument therein. The pump may be a pulsatile pump for providing a pulsed liquid circulation simulating blood flow. Also, the vessel simulating tube may include an elastic material (e.g., silicone) expandable with the pulsed liquid circulation. Furthermore, the vessel simulating tube may include a portion having an enlarged diameter simulating an aneurysm, or it may include a portion having a restriction simulating a stenosis. Alternately, the vessel simulating tube may include a portion simulating an arteriovenous malformation or tumor. |

DETAILED DESCRIPTION In view of the foregoing background, it is therefore an object of the invention to provide an apparatus for simulating certain vascular conditions, such as aneurysms, stenoses, or arteriovenous malformations.
This and other objects, features, and advantages in accordance with the present invention are provided by a medical simulation apparatus, which in one embodiment may include a housing, a vessel simulating tube carried by the housing, a liquid reservoir carried by the housing, a pump carried by the housing for circulating the liquid from the liquid reservoir through the vessel simulating tube, and an access port in fluid connection with the vessel simulating tube for receiving an instrument therein.
Accordingly, a catheter carrying a stent or other treatment device or instrument, for example, may be positioned through the access port to the vessel simulating tube.
The apparatus is not only useful for training, but may also be used for engineering evaluation, and/or sales presentations.
The pump may be a pulsatile pump for providing a pulsed liquid circulation simulating blood flow.
Also, the vessel simulating tube may include an elastic material (e.
g.
, silicone, rubber, or plastic) expandable with the pulsed liquid circulation.
The vessel simulating tube may also comprise glass.
Furthermore, the vessel simulating tube may include a portion having an enlarged diameter simulating an aneurysm, or it may include a portion having a restriction simulating a stenosis.
Alternately, it may include a porous material or tangle of passageways simulating an arteriovenous malformation or tumor.
The apparatus may also include a pressure release shunt connected in parallel with the vessel simulating tube for allowing the liquid to circulate if the vessel simulating tube becomes blocked.
A light source may be mounted in the housing for illuminating the vessel simulating tube.
More specifically, a translucent stage may be provided in the housing.
The vessel simulating tube may be mounted adjacent a top side of the translucent stage and the light source may be mounted adjacent a bottom side of the translucent stage
