DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here.

FIGS. 1 and 2 illustrate example environments in which one or more technologies may be implemented. An intraluminal power generation device may comprise intraluminal generator 100 configured for disposal within an anatomical lumen 101 defined by a lumen wall 102. The intraluminal generator 100 may be configured to convert a varying intraluminal pressure into energy (e.g. electrical energy, mechanical/elastic energy, chemical energy, thermal energy).

The intraluminal generator 100 may include an integrated pressure change receiving structure 103A configured to receive a pressure change associated with a fluid pressure within the lumen 101. Alternately, the pressure change receiving structure 103 may be an external pressure change receiving structure 103B operably coupled to the intraluminal generator 100 via a coupling 104 to transfer a received pressure from the pressure change receiving structure 103B to the intraluminal generator 100 in a form which the intraluminal generator 100 may convert to energy.

The intraluminal power generation device may comprise an energy storage apparatus 105 for storage of energy generated by the intraluminal generator 100. The energy storage apparatus 105 may be operably coupled to the intraluminal generator 100 by a coupling 106.

The intraluminal power generation device may comprise a power utilization device 107 that may use energy generated by the intraluminal generator 100 and/or stored in the energy storage apparatus 105 to carry out a desired function. The power utilization device 107 may be operably coupled to the intraluminal generator 100 and/or an energy storage apparatus 105 by a coupling 108.

FIG. 2 illustrates various configurations of one or more components of an intraluminal power generation device. The intraluminal generator 100 may be operably coupled to power utilization device 107A disposed in a first lumen 101A (e.g. in a distal relationship to the power utilization device 107A). An intraluminal generator 100 disposed within in a first lumen 101A may be operably coupled to power utilization device 107B disposed in a second lumen 101B.

The herein described subject matter may illustrate different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely exemplary, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “associated with” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being “operably connected,” or “operably coupled,” to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being “operably couplable,” to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and/or physically interacting components and/or wirelessly interactable and/or wirelessly interacting components and/or logically interacting and/or logically interactable components.

While particular aspects of the present subject matter described herein have been shown and described, changes and modifications may be made without departing from the subject matter described herein and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of the subject matter described herein. Furthermore, it is to be understood that the invention is defined by the appended claims. In general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). If a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
