[0046] The present invention will now be described, for purposes of explanation, in connection with numerous specific details in order to provide a thorough understanding of the subject invention. It will be evident, however, that the present invention can be practiced without these specific details without departing from the spirit and scope of this innovation.

[0047] An embodiment of an apparatus 10 for protecting a finger (i.e., a digit) during a medical procedure in accordance with an example embodiment of the invention will now be discussed in conjunction with FIGS. 1-5. Apparatus 10 is designed to provide a physician or other caregiver positive dexterity control of an implanted device (e.g., see 12 in FIGS. 4 and 5) which is targeted for removal. Referring first to FIGS. 1 and 2, apparatus 10 includes a generally tubular flexible member 14 disposed about a longitudinal axis A. Flexible member 14 includes a first layer 16, having an inner surface 16A and an outer surface 16B, a second layer 18 provided within first layer 16 on inner surface 16A thereof. In an example embodiment of the invention, first layer 16 is formed generally as a fabric sleeve, formed from a woven fabric material whereas second layer 18 in such example embodiment is formed from a gel material. In one example arrangement, a Silipos' mesh and ribbed knit tubes fully lined with a mineral oil gel has been utilized to provide all around digital protection while absorbing shock and pressure. In another example embodiment, both first layer 16 and second layer 18 are formed from fabric materials.

[0048] Continuing to refer to FIGS. 1 and 2, apparatus 10 further includes a guard section 20 which abuts first layer 16 and extends along a portion of flexible member 14 generally parallel to longitudinal axis A. Guard section 20 is generally positioned and structured to prevent a physician or practitioner from accidentally cutting the digit on which apparatus 10 is worn during a procedure. Accordingly, guard section 20 is formed from a suitable generally rigid material which is generally resistant to being cut. Some examples of suitable materials include, without limitation, plastics, ABS, PVC, Acetal (Delrin), Acrylic, HDPE, CPVC, CTFE, Cast Nylon, Glass filled nylon and Kevlar filled nylon, PEEK, PETG, Polycarbonate, and PTFE. In the example embodiment illustrated in FIGS. 1-5, guard section 20 includes a plurality of rigid plate members 22 provided on outer surface 16B of first layer 16. In the example shown in FIGS. 1-5, each plate member is disposed generally perpendicular to longitudinal axis A, however, it is to be appreciated that plate members 22 may be disposed in other arrangements without varying from the scope of the invention. As can be appreciated from the sectional view of FIG. 2, each plate member 22 of guard section 20 extends over approximately of the circumference of flexible member 14 so as to generally provide a protective guard for the digit on which apparatus 10 is disposed while still allowing for at least some flexibility of the digit.

[0049] FIG. 3 is an example wherein apparatus 10 is disposed on the right thumb 30 of a physician/practitioner. FIGS. 4 and 5 show a partially schematic example wherein apparatus 10 is disposed on the right thumb of a physician/practitioner and is being used in a procedure wherein a portion 32 of a patient's skin is generally pinched between apparatus 10 and the physician's/practitioner' s index finger 34. During such procedure an incision 36 has been made using a scalpel in order to insert or remove device 12. Although shown disposed protecting a thumb, it is to be appreciated that the embodiments of apparatus 10 may be employed to protect other fingers without varying from the scope of the invention. It is also to be appreciated that multiple apparatuses 10 may be employed to protect more than one finger at a given time without varying from the scope of the invention.

[0050] An embodiment of another apparatus 10 for protecting a digit during a medical procedure in accordance with another example embodiment of the invention is shown in FIGS. 6-8. Apparatus 10 is a generally similar arrangement as apparatus 10 previously discussed except apparatus 10 includes a guard section 20 which is in the form of a single plate member 22 which is provided on outer surface 16B of first layer 16 and extends along a portion of flexible tubular member 14, generally parallel to longitudinal axis A. Plate member 22 is formed from a suitable cut-resistant material or materials such as previously described herein. Plate member 22 includes a saddle portion 40 which is generally centrally located in plate member 22. Referring to FIG. 6, plate member 22 has a first thickness t.sub.1 and a second thickness t.sub.2 in saddle portion 40 which is less than first thickness t.sub.1. As can be appreciated from FIG. 7, plate member 22, as well as saddle portion 40 thereof, extends approximately of the circumference of generally tubular flexible member 14. FIG. 8, similar to FIG. 3, shows an example of apparatus 10 disposed on the right thumb 30 of a physician/practitioner.

[0051] An embodiment of yet another apparatus 10 for protecting a digit during a medical procedure in accordance with yet another example embodiment of the invention is shown in FIGS. 9-11. Apparatus 10 is a generally similar arrangement as apparatuses 10 and 10 previously discussed except apparatus 10 includes a guard section 20 which is in the form of a single plate member 22 which is provided abutting inner surface 16A of first layer 16 and extends along a portion of flexible tubular member 14, generally parallel to longitudinal axis A. Plate member 22 is formed from a suitable cut-resistant material or materials such as previously described herein. Similar to plate member 22, plate member 22 includes a saddle portion 40 which is generally centrally located in plate member 22. Referring to FIG. 9, plate member 22 has a first thickness t.sub.1 and a second thickness t.sub.2 in saddle portion 40 which is less than first thickness t.sub.1. As can be appreciated from FIG. 10, plate member 22, as well as saddle portion 40 thereof, extends approximately of the circumference of generally tubular flexible member 14. FIG. 11, similar to FIGS. 3 and 8, shows an example of apparatus 10 disposed on the right thumb 30 of a physician/practitioner (although other fingers could be protected). As guard section 20 is disposed within apparatus 10, an indicia 50 (shown with exaggerated thickness in FIGS. 9-11) may be provided on outer surface 16B of first layer 16 so as to ensure proper alignment of apparatus 10 during a procedure. For example, without limitation, indicia 50 may be any suitable notifier (e.g., printing, dashed/solid line, graphics, etc.) and may be printed, stitched, or applied via any suitable process, without varying from the scope of the invention.

[0052] From the foregoing description of some exemplary embodiments, it is to be appreciated the guard section of the apparatus is generally designed to provide a wearer's digit (e.g., thumb, index finger, etc.) protection against injury from accidental scalpel slippage. The guard sections also provide a stable positioning platform for insertion or removal of the implanted device. It is also to be appreciated that the apparatus may be designed to be a one-time use instrument which is part of a pre-assembled implanted device removal kit. The general design of the apparatus allows for both right handed and left handed use.

[0053] While the device of the disclosed concept has been described herein in connection with the removal of an implantable medication delivery system, it will be appreciated that that is meant to be exemplary only, and that the device of the disclosed concept has application in other medical procedures which require one or more incisions to be made.

[0054] In the claims, any reference signs placed between parentheses shall not be construed as limiting the claim. The word comprising or including does not exclude the presence of elements or steps other than those listed in a claim. In a device claim enumerating several means, several of these means may be embodied by one and the same item of hardware. The word a or an preceding an element does not exclude the presence of a plurality of such elements. In any device claim enumerating several means, several of these means may be embodied by one and the same item of hardware. The mere fact that certain elements are recited in mutually different dependent claims does not indicate that these elements cannot be used in combination.

[0055] Although the invention has been described in detail for the purpose of illustration based on what is currently considered to be the most practical and preferred embodiments, it is to be understood that such detail is solely for that purpose and that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover modifications and equivalent arrangements that are within the spirit and scope of the appended claims. For example, it is to be understood that the present invention contemplates that, to the extent possible, one or more features of any embodiment can be combined with one or more features of any other embodiment.
