A GUIDE DEVICE FOR INTRODUCING AT LEAST A SURGICAL INSTUMENT INTERNALLY OF AN ORGANIC CAVITY, IN PARTICULAR A VASCUALR CAVITY

A guide device (1) for introducing at least a surgical instrument internally of an organic cavity (2), in particular a vascular cavity comprises a guide body or guide catheter (3) which is substantially hollow and flexible and exhibits an open directing end (8) which is transversal. The device comprises an elongated and flexible guide element (9), which is slideable internally of the guide body (3) to define an advancing guide for the guide body (3). The device (1) also includes means for stabilising (10) for easily piloting the directing end (8) with respect to the transfersal cavity (2b) and for advancing the guide catheter. The means for stabilising and defining by a stabilising opening (11) and by the elongate and flexible stabilising element (12) which internally engages the guide body (3) and exits therefrom through the stabilising opening (11) along the cavity occupied bu the guide wire (3). The stabilising element (12) behaves as a rotation pivot by means of which the operator doing the operation can easily align the directing end (8) of the guide body (3) with the transversal cavity (2b), and the directing end (8) into the transversal cevity (2b).
