Dilator device
First Claim
1. A dilator device comprising:
- an elongated sleeve having a hollow interior extending along a length thereof,an access opening disposed on a proximal portion of said sleeve in communicating relation with said hollow interior,said elongated sleeve comprising a tip disposed on a distal portion thereof,an open end formed on said tip and disposed in communicating relation with said hollow interior,a bladder connected to said distal portion of said sleeve and extendable outwardly therefrom in an expanded orientation,a fluid input for a fluid source connected to said sleeve in fluid communication with said bladder,said access opening and said hollow interior structured and dimensioned to removably receive therein a positioning instrument, andsaid tip comprising a predetermined configuration that facilitates positioning of said elongated sleeve within an intended body part;
wherein said tip comprises a navigation interface; and
wherein said navigation interface comprises a component disposed on said tip and structured to at least partially define a magnetic interface with an external device.

Abstract
A dilator device including an elongated flexible material sleeve having a hollow interior extending along a distal portion and a proximal portion thereof. An expandable or inflatable bladder is connected to the distal portion and disposable radially outward from an exterior of the sleeve when in an expanded and/or inflated orientation. The elongated sleeve comprising a tip having a predetermined configuration that facilitates positioning the elongated sleeve within an intended body part. A fluid input is structured for removable connection to a fluid source and is disposed on the sleeve, in fluid communication with the bladder and a flow restrictor is structured to restrict fluid flow from the bladder to an exterior of the sleeve. An access opening is formed on the proximal portion and is cooperatively dimensioned with the hollow interior to removably receive any one of a plurality of different types of positioning instruments within the sleeve.

12. A dilator device comprising:
-
an elongated sleeve having a hollow interior extending along a length thereof, an access opening disposed on a proximal portion of said sleeve in communicating relation with said hollow interior, said elongated sleeve comprising a tip disposed on a distal portion thereof, an open end formed on said tip and disposed in communicating relation with said hollow interior, a bladder connected to a distal portion of said sleeve and extendable outwardly therefrom in an expanded orientation, a fluid input for a fluid source connected to said sleeve in fluid communication with said bladder, said access opening and said hollow interior structured and dimensioned to removably receive therein a positioning instrument, said tip comprising a substantially tapered configuration, said elongated sleeve comprising a predetermined structural integrity, and said substantially tapered configuration and said predetermined structural integrity cooperative to facilitate positioning of said sleeve within an intended body part;
wherein said elongated sleeve comprises an outer layer and an inner layer connected to one another and extending substantially along the length of said elongated sleeve;
said outer layer disposed in at least partially enclosing relation to said inner layer; and
wherein said fluid input comprises a conduit integrated at least partially into said sleeve between said inner layer and said outer layer. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
