Abstract

Anatomical models representing one or more anatomical structures of a human or non-human animal and related methods for demonstrating, training, promotion and sale of medical, cosmetic and surgical products or procedures. A working device is inserted into the anatomical model and used to perform a simulated procedure, thereby causing an indicator apparatus (e.g., a removable business card) to become perceptibly altered. The indicator apparatus may then be removed and provided a potential user, consumer or purchaser of the medical, surgical or cosmetic product.

Claims

1. A device comprising:

an anatomical model representing one or more anatomical structures of a human or non-human animal;

an opening in the model through which a working device may be inserted and advanced to a desired procedure location and used to enlarge or dilate an opening, channel, lumen, indentation, gap or other structure; and

an indicator apparatus that provides an indication of when the working device has been used to effect a desired enlargement or dilation of an opening, channel, lumen, indentation, gap or other structure, said indication being discernible without requiring substantial dismantling or destruction of the anatomical model;

wherein the indicator apparatus comprises a removable card member which has, formed therein, an opening, channel, lumen, indentation, gap or other structure which becomes enlarged or dilated when the working device has been used to cause enlargement or dilation of that opening, channel, lumen, indentation, gap or other structure.

2. A device according to claim 1 wherein the opening in the model through which a working device may be inserted represents a natural body opening.

3. A device according to claim 1 wherein the opening in the model through which a working device may be inserted is shaped and located to represent a body opening of a human or animal subject, said body opening being selected from the group consisting of:

the mouth, nose, ear, anus, urethra, vagina and exocrine duct.

4. A device according to claim 1 wherein the opening in the model through which a working device may be inserted represents a man-made or non-naturally occurring body opening.

5. A device according to claim 1 wherein the opening in the model through which a working device may be inserted is shaped and located to represent an opening that has been created in the body of a human or animal subject, said opening being selected from the group consisting of:

incision, puncture tract, port, opening resulting from pathology and opening resulting from congenital deformity.

6. A device according to claim 1 wherein the removable card member is positionable on or in the anatomical model before attempting performance of a desired procedure and subsequently removable from the anatomical model after attempting performance of the desired procedure.

7. A device according to claim 6 wherein the removable card member is formed of at least one material selected from the group consisting of:

cardboard, plastic, foamed plastic, paper, metal and glass.

8. A device according to claim 6 wherein the removable card member has a name or promotional information thereon.

9. A system comprising a device according to claim 1 further in combination with a working device that is insertable through the opening in the model, the working device having a working part that is useable to enlarge or dilate the opening, channel, lumen, indentation, gap or other structure formed in the removable card member.

10. A system according to claim 9 wherein the working device comprises a balloon catheter and wherein the working part comprises a balloon.

11. A device according to claim 1 further comprising a reference region in the removable card member for comparison to the opening, channel, lumen, indentation, gap or other structure.

12. A device according to claim 1 wherein the model is constructed to represent one or more anatomical structures within the ear, nose or throat.

13. A device according to claim 12 wherein the opening, channel, lumen, indentation, gap or other structure formed in the removable card member represents an opening into a paranasal sinus.

14. A device or system according to claims 1 wherein one or more portion(s) of the model is/are removable and/or malleable and/or reconfigurable and/or replaceable to represent different anatomical structures, variations or conditions.

15. A system comprising a device according to claim 14 in combination with one or more replacement parts that may be used to replace a removed portion of the model.

16. A system according to claim 15 wherein the one or more replacement parts are removable and/or malleable and/or reconfigurable and/or replaceable to represent structures, variations or conditions selected from:

a) normal anatomical variations, b) disease states or disorders, c) effects of pathology, d) etiological stages of pathology, e) congenital malformations, f) anatomical anomalies, g) effects of prior surgery, h) effects of prior therapy, i) effects of drug administration, j) effects of aging or maturation, etc.

17. A system according to claim 16 wherein the model represents one or more anatomical structures within the ear, nose or throat and wherein the one or more replacement parts are removable and/or malleable and/or reconfigurable and/or replaceable to represent structures, variations or conditions selected from:

a) ostia of paranasal sinuses, b) ethmoid cells, c) various types of frontal ethmoid cells, d) Onodi cells, e) Haller cells, f) septations in frontal, maxillary, sphenoid sinuses, g) variations in size and shape of paranasal sinuses, h) the effects of prior sinus or ENT surgery, I) prior ethmoidectomy, j) prior uncinectomy, k) prior frontal sinusotomy, l) mucoceles, m) polyps, n) papillomas, o) carcinoma, p) inflamed mucosa, q) osteoneogenesis, r) scarring/narrowing/adhesions, s) deviated septum, t) concha bullosa, u) paradoxical turbinates, v) agger nasi cells, w) variations in size of turbinates, uncinate, etc., x) superior and supreme turbinates, y) optic nerve, z) lachrymal duct, aa) anterior ethmoid artery, bb) retrobullar recesses, cc) suprabullar recesses, dd) inferior turbinates and ee) normal or atresic Eustachian tubes.

18. A system according to claim 15 wherein the one or more replacement parts are detachably attachable to the model by way of one or more detachable attachment means selected from the group consisting of:

slots or cavities that fit a locking portion of the detachable element;

magnetic attachments;

hook and loop type fasteners;

screw type fasteners;

adhesives and suction cups.

19. A method for distributing promotional or business information, said method comprising the steps of:

A) positioning, on or in an anatomical model, a removable card member having promotional or business information thereon;

B) using a medical, surgical or cosmetic product to perform a simulated procedure on or in the anatomical model in a manner that perceptibly affects the removable card member; and

C) removing the removable card member and providing it to a prospective user, consumer or purchaser of the medical, surgical or cosmetic product.

20. A method according to claim 19 wherein an opening is formed in the removable card member and wherein the simulated procedure causes the opening to become enlarged.

21. A method according to claim 20 wherein the removable card member further includes a reference opening for comparison to the enlarged opening.

22. A method according to claim 19 wherein the promotional or business information comprises name of a developer of or commercial source for the medical, surgical or cosmetic product.
