[0032] FIG. 1 schematically illustrates a device or apparatus 100 according to an implementation. The apparatus 100 includes an elongate member 110 that defines a lumen 120. The elongate member 110 may be a tubular member or cylindrical in shape and may be configured to be placed such that at least a portion of the elongate member 110 may be disposed within a body of a patient. For example, in some implementations, the elongate member 110 may be disposed within a body of a patient such as to provide access to a location within or internal to the body of the patient. In some implementations, a doctor or physician may access the internal location within the body of the patient via the lumen 120 defined by the elongate member 110. In some implementations, a secondary medical device, such as a scope, a lithotripsy device, or other medical device may be inserting through the lumen 120 of the elongate member 110 to or towards the internal location within the body of the patient.

[0033] In the illustrated implementation, the apparatus 100 also includes a flow meter 140. The flow meter 140 is configured to detect or measure fluid flow at a location proximate the apparatus 100. For example, in some implementations, the flow meter 140 is configured to detect or measure fluid flow within the lumen 120 defined by the elongate member 110. In some implementations, the flow meter 140 may be disposed within the lumen 120 defined by the elongate member 110.

[0034] In the illustrated implementation, the apparatus 100 includes a pressure sensor 150. The pressure sensor 150 is configured to detect or measure a pressure at a location proximate the apparatus 100. For example, in some implementations, the pressure sensor 150 is disposed at a distal end portion of the elongate member 110 and is configured to detect or measure a pressure within the body of the patient proximate the elongate member 110. For example, in some implementations, the pressure sensor 150 is configured to measure the pressure in a kidney or a bladder of a patient. In other implementations, the pressure sensor 150 is configured to measure the pressure within a different portion of the body of the patient. In some implementations, the pressure sensor 150 is configured to measure pressures between 0 and 400 mmHg.

[0035] In use, in some implementations, the apparatus 100 may be used in medical procedures. The elongate member 110 may be inserted into the body of the patient such that a proximal end portion of the elongate member 110 extends from the body of the patient and the distal end portion of the elongate member 110 is disposed within the body of the patient. A physician may then access the internal location within the body of the patient via the lumen 120 defined by the elongate member 110. The physician may utilize a secondary medical device by, for example, inserting such secondary medical device into the lumen 120.

[0036] In some implementations, the flow meter 140 is configured to detect or measure fluid flow within the lumen 120. For example, the fluid flow may be measured during the medial procedure and may be displayed to the physician on a display.

For example, in some implementations, the elongate member 210 may be disposed within a body of a patient such as to provide access to a location within or internal to the body of the patient. In some implementations, a doctor or physician may access the internal location within the body of the patient via the lumen defined by the elongate member 210. In some implementations, a secondary medical device, such as a scope, a lithotripsy device, or other medical device may be inserting through the lumen of the elongate member 210 to or towards the internal location within the body of the patient.

[0039] In the illustrated implementation, the system 200 includes a flow / pressure measurement module 280. In some implementations, the flow / pressure measurement module 280 is configured to detect or measure fluid flow within lumens defined by the elongate member 210 and pressure proximate the elongate member 210. In the illustrated implementation, the flow / pressure measurement module 280 includes a flow meter. The flow meter is configured to detect or measure fluid flow at a location proximate the apparatus 200. For example, in some implementations, the flow meter is configured to detect or measure fluid flow within the lumen defined by the elongate member 210. In some implementations, the flow meter is configured to detect or measure fluid flow within the inflow channel 216, or the outflow channel 218, or both. In some implementations, the measurement module 280 is configured to filter raw data to reduce the noise within the data. In some implementations, the measurement module 280 includes an analog or digital components configured to help filter the raw data.

[0040] In the illustrated implementation, the system 200 includes a pressure sensor. The pressure sensor is configured to detect or measure a pressure at a location proximate the elongate member 210. For example, in some implementations, the pressure sensor is disposed at a distal end portion of the elongate member 210 and is configured to detect or measure a pressure within the body of the patient proximate the elongate member 210.

[0041] The flow / pressure measurement module 280 is operatively coupled to a flow control module 290. The flow control module 290 is configured to control the fluid flow within the inflow channel or lumen 216 and the outflow channel or lumen 218. In the illustrated implementation, the flow control module 290 is operatively- coupled to an inflow pump 292. The inflow pump 292 is configured to pump fluid into the inflow channel 216. In the illustrated implementation, the flow control module 290 is also operatively coupled to an outflow pump 294. The outflow pump 294 is operatively coupled to the outflow channel 218 and is configured to pump fluid out of a body of a patient via the outflow channel 218. In some implementations, the flow control module 290 is configured to aspirate, irrigate, or limit the fluid flow. The flow control module 290 may include or be operatively coupled to a user interface that may include, for example, a touch screen. In some implementations, the flow control module 290 may also control the temperature or provide heated or warmed fluid.

[0042] In some implementations, the flow / pressure measurement module 280 and the flow control module 290 are incorporated together in a single unit. In other implementations, the flow / pressure measurement module 280 and the flow control module 290 are separate units or devices and are operatively coupled. For example, the flow / pressure measurement module 280 and the flow control module 290 may be operatively coupled together via a wire or other mechanism.
