System and method for medical diagnostics

1. A medical device comprising:

an outer sleeve having a hollow interior and open distal and proximal ends, the outer sleeve including a proximal section having a substantially conical shape;

a core configured to be inserted axially within the hollow interior of the outer sleeve, the core including an axial inner cavity, the core further including a proximal section having a conical shape substantially conforming to that of the proximal section of the outer sleeve; and

a sample collecting assembly comprising:

a hollow rotatable shaft extending through the axial inner cavity of the core, the shaft having an engagement member positioned at a proximal end of the shaft;

an ejector pin extending through the hollow rotatable shaft; and

a sample collector distally coupled to the ejector pin,

wherein axial movement of the conical proximal section of the core into the substantially conical proximal portion of the outer sleeve causes deployment of the sample collecting assembly and in which a compressive force applied to the substantially conical proximal section of the outer sleeve causes the proximal section of the core and the sample collecting assembly to be axially retracted.

2. The medical device of claim 1 , wherein the ejector pin includes at least one retention feature.

3. The medical device of claim 1 , wherein the outer sleeve further comprises a distal expansion section that is configured to transition between a closed position and an open deployed position when the conical proximal section of the core is axially moved into the substantially conical proximal section of the outer sleeve.

4. The medical device of claim 3 , wherein the distal expansion section comprises a plurality of fingers which are movable between the closed position and the open deployed position based on the axial movement of the core.

5. The medical device of claim 4 , further comprising a flexible sheath extending over the plurality of fingers.

6. The medical device of claim 1 , wherein the substantially proximal conical section of the outer sleeve comprises at least two locator pads spaced apart from each other circumferentially to facilitate compression.

7. The medical device of claim 1 , wherein the ejector pin is selectively engageable to axially advance the ejector pin and eject the sample collector from the sample collecting assembly.

8. The medical device of claim 7 , wherein the engagement member is a rotatable knob that comprises a recessed center portion sized to retain the ejector pin in a safety position to prevent unintentional ejection of the sample collector.

9. The medical device of claim 1 , wherein the sample collector comprises a coupling portion configured to releasably couple the sample collector to a distal end of the ejector pin, the coupling portion comprising one of a keyway and a key and the distal end of the ejector pin comprising the other of the keyway and the key to facilitate rotation of the sample collector.

10. The medical device of claim 1 , wherein the sample collector comprises a brush.

11. The medical device of claim 1 , further comprising an imaging device extending through the axial cavity of the core.

12. The medical device of claim 1 , further comprising at least one stop surface positioned on an inner surface of the outer sleeve to prevent unintentional ejection of the core from the outer sleeve.

13. The medical device of claim 10 , wherein the brush comprises at least one of at least one key or keyway for engaging the other of at least one keyway or key on the hollow shaft or core.

14. The medical device of claim 10 , wherein the brush includes one of angled bristles or a shaft retaining the bristles that is angled or curved relative to a primary axis of the device.

15. A method of manufacturing a medical diagnostic device, the method comprising:

providing an outer sleeve having a hollow interior and open distal and proximal ends, the outer sleeve including a proximal section having a conical shape;

providing a core configured to be inserted axially within in the outer sleeve, the core including an axial cavity and a proximal section having a conical shape substantially conforming to the proximal section of the outer sleeve, and

providing a diagnostic assembly within the core.

16. The method of claim 15 , wherein the diagnostic assembly provided is a sample collecting assembly made from the steps of:

providing a hollow rotatable shaft extending through the axial cavity of the core, the shaft having an engagement member positioned at a proximal end of the shaft and retained within the conical section of the core;

providing an ejector pin extending entirely through the hollow rotatable shaft; and

providing a sample collector coupled to the ejector pin.

17. The method of claim 15 , wherein the diagnostic assembly comprises an imaging device and in which the method further comprises positioning the imaging device in a sampling end of the axial cavity of the core.

18. The method of claim 15 , further comprising the step of configuring a distal expansion section of the outer sleeve to transition between an unopened insertion position and an open deployed position.

19. The method of claim 17 , further comprising the step of permitting the sample collector to rotate while restricting the rotational movement of the imaging device.
