Abstract

Exemplary embodiments of a method, device, and apparatus for positioning an apparatus on a location of a tissue. For example, a substantially rigid film over an area of tissue to be treated can be provided. The film can include a positioning arrangement that facilitates a particular spatial engagement with the apparatus. The exemplary method can further include applying a portion of the film to a portion of a surface of the tissue and positioning the apparatus at the location by the engagement of the film to the apparatus using the feature of the film.

Claims

1-35. -35. (canceled)

36. A system for ablating at least one particular location of a biological tissue, comprising:

a film configured to engage with at least one portion of a surface of the tissue that includes the at least one particular location; and

a device comprising a source of ablative electromagnetic radiation,

wherein the film comprises at least one first feature, and the device comprises at least one second feature,

wherein at least one portion of the film comprises an ablatable material,

wherein the at least one first feature is structured or configured to engage with the at least one second feature of the device to position the device over the particular location, such that, in operation, the device ablates a hole through the film over the at least one particular location, and ablates a hole in the tissue at the at least one particular location when the device is activated.

37. The system of claim 36, wherein the film comprises at least one of a plastic or a polymer.

38. The system of claim 36, wherein the source of ablative electromagnetic radiation comprises an ablative laser.

39. The system of claim 36, wherein the film is engaged with the surface of the tissue using at least one of a surgical glue, a cyanoacrylate compound, a cement, a glue, an epoxy, or a curable polymer.

40. The system of claim 36, wherein the at least one first feature includes a first positioning arrangement and the at least one second feature includes at least one second positioning arrangement.

41. The system of claim 40, wherein each of the first and second positioning arrangements comprises at least one of a recess, a protrusion, a groove, a track or a magnetic material.

42. The system of claim 36, further comprising a further device,

wherein the further device comprises at least one third feature that is structured or configured to engage with the at least one first feature of the film to position the further device over the at least one particular location, and

wherein the further device is configured to generate a further effect in the ablated hole at the at least one particular location.

43. The system of claim 42, wherein the further device comprises a source of further electromagnetic radiation, and the further device is configured to direct the further electromagnetic energy into the ablated hole at the at least one particular location.

44. The system of claim 42, wherein the further device is configured to insert an object at least partially into the ablated hole at the at least one particular location.

45. The system of claim 44, wherein the object is at least one of a probe, a waveguide, a sensor, a needle, or an optical fiber.

46. The system of claim 36, wherein the at least one first feature comprises a first track arrangement and the at least one second feature comprises a second track arrangement, and wherein the at least one first and second track arrangements are configured to engage one another such that the device is constrained to follow a particular path over the film.

47. The system of claim 46, wherein each of the first and second track arrangements comprises at least one of a guide, a ridge, a groove, or a track.

48. The system of claim 46, further comprising:

at least one marker provided at least one of on or proximal to the at least one first track arrangement; and

at least one sensor associated with the device,

wherein the at least one sensor is configured to detect the at least one marker when the first and second track arrangements are engaged with one another and the device is located at a certain position relative to the film.

49. The system of claim 48, wherein the at least one marker includes at least one of a bump, a notch, a magnetic element, or a pigmented marking.

50. The system of claim 48, wherein the at least one sensor is configured to provide a signal to control an aspect of the device when it detects the at least one marker.

51. A method for affecting a biological tissue at least one particular location, comprising:

adhering a film comprising an ablatable material to at least one portion of a surface of the tissue that includes the at least one location, wherein the film comprises at least one first feature;

providing a device comprising a source of ablative electromagnetic radiation and at least one second feature,

engaging the at least one first feature with the at least one second feature to position the device at a certain position relative to the at least one particular location; and

activating the device to ablate a hole through the film over the at least one particular location and to further ablate a hole in the tissue at the at least one particular location.

52. The method of claim 51, further comprising:

providing a further device comprising at least one third feature;

engaging the at least one third feature with the at least one first feature of the film to position the further device at the certain position relative to the at least one particular location; and

activating the further device to generate a further effect in the ablated hole at the at least one particular location.

53. The method of claim 52, wherein the further device comprises a source of a further electromagnetic radiation, and wherein the further effect comprises directing the further electromagnetic radiation into the ablated hole at the at least one particular location.

54. The method of claim 52, wherein generating the further effect comprises inserting an object at least partially into the ablated hole at the at least one particular location.

55. The method of claim 54, wherein the object is at least one of a probe, a waveguide, a sensor, a needle or an optical fiber.
