FIG. 1 is a schematic illustration of a medical device 100 according to an embodiment of the invention. The medical device 100 may be used in surgical procedures. For example, in some embodiments the medical device 100 may be placed within a body of a patient to create an access or port for further medical procedures. More specifically, in some embodiments, the medical device 100 may be placed within the body of the patient such that a distal end portion of the medical device 100 is disposed within the body of the patient and a proximal end portion of the medical device 100 extends from the body of the patient. In some embodiments, an additional or secondary medical device may be inserted into the body of the patient via the medical device 100 to perform an additional medical procedure.

In the illustrated embodiment, the medical device 100 includes an elongate member 110 and a sleeve 150. The elongate member 110 has a first or proximal end portion 112 and a second or distal end portion 114. In some embodiments, the elongate member 110 defines a lumen that extends from the first or proximal end portion 112 to the second or distal end portion 114.

In some embodiments, the elongate member 110 is linear or substantially straight or linear. In other embodiments, the elongate member 110 is curved or is flexible and may form a curve or have a curved portion. In some embodiments, the elongate member 110 may be tubular or have a round or circular cross-sectional shape. In other embodiments, the elongate member 110 has a different cross-sectional shape, such as square, rectangular, triangular, or any other shape.

In some embodiments, second or distal end portion 114 of the elongate member 110 may be placed in a first configuration (or collapsed configuration) or a second configuration (or expanded configuration). The second end portion 114 of the elongate member 110 has a first size when the second end portion 114 is in its first configuration. The second end portion 114 has a second size when the second end portion 114 is in its second configuration. The first size is smaller than the second size. In some embodiments, the second end portion 114 is biased to its second or expanded configuration.

The sleeve 150 is movably coupled to the elongate member 110. In some embodiments, the sleeve 150 defines a lumen. In such embodiments, the lumen may receive at least a portion of the elongate member 110 such that the elongate member 110 may move with respect to the sleeve 150.

The sleeve 150 is configured to retain the second end portion 114 of the elongate member in its first or collapsed configuration. In some embodiments, the sleeve 150 includes a contact portion or a contact surface. The contact portion or the contact surface is configured to contact the second end portion 114 of the elongate member 110 to help retain or force the second end portion 114 of the elongate member 110 in its first or collapsed configuration.

In use, the medical device 100 may be inserted into a body of a patient. In some embodiments, the medical device 100 may be inserted into the body of the patient while the second end portion 114 of the elongate member 110 is in its first or collapsed configuration. For example, in some embodiments, the medical device 100 may be inserted into the body of the patient while the contact portion or contact surface of the sleeve 150 is in contact with the second end portion 114 of the elongate member 110 to retain the second end portion 114 of the elongate member 110 in its first or collapsed configuration.

In some embodiments, the medical device 100 may be inserted into the body of the patient such that the second or distal end portion 114 of the elongate member 110 is disposed within the body of the patient and the first or proximal end portion 112 of the elongate member 110 is disposed outside of the body of the patient (or extends from the body of the patient).

The second end portion 114 may then be moved from its first or collapsed configuration to its second or expanded configuration. For example, in some embodiments, the elongate member 110 is moved with respect to the sleeve 150 such that the contact portion or contact surface of the sleeve disengages or is removed from the second end portion 114 of the elongate member 110. The second end portion 114 of the elongate member 110 may then move to its second or expanded configuration. In some embodiments, the second end portion 114 of the elongate member 110 is biased to its second or expanded configuration and will move to such configuration in the absences of an external or retaining force.

In some embodiments, the second end portion 114 of the elongate member 110 is configured to retain or help retain the medical device 100 in place within the body of the patient. Specifically, in some embodiments, the second end portion 114 in its second or expanded configuration is configured to contact bodily tissue of the patient to retain or help retain the medical device 100 in place within the body of the patient.

In some embodiments, the elongate member 110 defines a lumen. Once the medical device 100 is disposed within the body of the patient, other medical devices may be inserted into the body of the patient though the lumen defined by the elongate member 110. Accordingly, such other or secondary medical devices may be used to perform additional medical procedures once such device is disposed within the body of the patient.

FIGS. 2 and 3A are side views of a medical device 200 according to an embodiment of the invention. FIG. 3B is a cross-sectional view of a portion of the medical device 200. The medical device 200 may be used in surgical procedures. For example, in some embodiments the medical device 200 may be placed within a body of a patient to create an access or port for further medical procedures. For example, in some embodiments, the medical device 200 may be placed within a body of a patient and used in a percutaneous nephrolithotomy procedure. In some embodiments, as best illustrated in FIG. 11, the medical device 200 may be placed within the body of the patient such that a distal end portion of the medical device 200 is disposed within the body of the patient and a proximal end portion of the medical device 200 extends from the body of the patient. In some embodiments, an additional or secondary medical device may be inserted into the body of the patient via the medical device 200 to perform an additional medical procedure.

In the illustrated embodiment, the medical device 200 includes an elongate member 210 and a sleeve 250. As will be described in more detail below, FIG. 2 illustrates the elongate member 210 with its distal end portion 214 in a first or collapsed configuration and FIG. 3A illustrates the elongate member 210 with its distal end portion 214 in a second or expanded configuration.

FIG. 4 is a side view of the elongate member 210. FIG. 5 is a side view of the distal end portion 214 of the elongate member 210. FIG. 6 is a cross-sectional view of the elongate member 210 taken along line A-A of FIG. 4. FIG. 7 is a cross-sectional view of the elongate member 210 taken along line B-B of FIG. 4.

The elongate member 210 has a first or proximal end portion 212 and a second or distal end portion 214. The elongate member 210 defines a lumen 216 that extends from the first or proximal end portion 212 to the second or distal end portion 214.

In the illustrated embodiment, the elongate member 210 is linear or substantially linear. Specifically, the elongate member 210 extends along a longitudinal axis LA1. In other embodiments, the elongate member 210 is curved or is flexible and may form a curve or have a curved portion.

As best illustrated in FIG. 6, the elongate member 210 may be tubular or have a round or circular cross-sectional shape (the cross-section that is disposed orthogonal or substantially orthogonal to the longitudinal axis LA1 of the elongate member 210). In other embodiments, the elongate member 210 has a different cross-sectional shape, such as square, rectangular, triangular, or any other shape.

The second or distal end portion 214 of the elongate member 210 may be placed in a first configuration (or collapsed configuration) or a second configuration (or expanded configuration). The second end portion 214 of the elongate member 210 has a first size 51 when the second end portion 214 is in its first configuration. For example, as will be described in detail below and as illustrated in FIG. 2, the second end portion 214 is in its first configuration and has a size or width 51 when the second end portion 214 is disposed within the sleeve 250. The second end portion 214 has a second size or width S2 when the second end portion 214 is in its second configuration. As best illustrated in FIG. 3A, the second end portion 214 is in its second configuration and has the second size S2 when the second end portion 214 is disposed outside of the sleeve 250. The first size 51 is smaller than the second size S2.

As best illustrated in FIG. 5, the second end portion 214 includes support members 222 that extend longitudinally or substantially longitudinally. The support members 222 are configured to expand or separate when the second end portion 214 is disposed outside of the sleeve 250. In some embodiments, the support members 222 are formed of a biocompatible material. In some embodiments, the support members 222 are formed of the same material that is used to form the sleeve 250. In some embodiments, the support members 222 have a thickness that is larger than the thickness of the sleeve 250. Extension portions 223 extend between the support members 222. In some embodiments, the extension portions 223 are more flexible than the support members 222. In some embodiments, the flexibility of the extension portions 223 facilitates the expansion of the second end portion 214 to its larger or flared configuration. In some embodiments, the extension portions 223 are formed of a material that is more flexible than the material that is used to form the support members 222. In some embodiments, the second end portion 214 can be formed of a molded thermoplastic or a shaped metal material or a metal support on a polymeric member. In some embodiments, the support members 222 may be formed of acetal or polyetherimide. In other embodiments, the support members 222 are formed of polyethylene, polypropylene, polyvinyl chloride, nitinol or stainless steel.

In some embodiments, an outer surface 221 of the second end portion 214 is configured to grip or adhere to bodily tissue of the patient to help retain the device 200 in place within the body of the patient. In some embodiments, the outer surface 221 includes an material or a coating that has a relatively high coefficient of friction to help grip or adhere to the bodily tissue or anatomy of the patient. In some embodiments, the second end portion 214 includes anchoring members or points 225. The anchoring members or points 225 may be raised or protruding portions that help the second end portion 214 grip or adhere to the bodily tissue or anatomy of the patient when the device is in its expanded configuration. The anchoring members or points 225 may be of any shape or size. In some embodiments, the anchoring members or points 225 are rectangular in shape. In other embodiments, the anchoring members or points 225 are circular in shape. In some embodiments, the anchoring members or points 225 may be circumferentially distributed or arraigned in a row or a plurality of rows.

In some embodiments, a gel may coat or cover a portion of the anchoring members 225. The gel may be a biodegradable or medical gel and may have a relatively high coefficient of friction. Thus, in some embodiments, the gel may help the second end portion 214 grip or adhere to the bodily tissue or anatomy of the patient when the device is in its expanded configuration. In some embodiments, the gel may be gel pads. In some embodiments, the gel may be or include a silicone gel.

FIG. 8 is a side view of the sleeve 250. FIG. 9 is a cross-sectional view of the sleeve 250 taken along line C-C (which is orthogonal or substantially orthogonal to the longitudinal axis LA2 of the sleeve 250) of FIG. 8. FIG. 10 is another cross-sectional view of the sleeve 250. The sleeve 250 is movably coupled to the elongate member 210. In in the illustrated embodiment, the sleeve 250 defines a lumen 256. The lumen 256 extends from a first end portion 252 of the sleeve 250 to a second end portion 254 of the sleeve. The lumen 256 may receive at least a portion of the elongate member 210 such that the elongate member 210 may move or slide with respect to the sleeve 250.

The sleeve 250 is configured to retain the second end portion 214 of the elongate member 210 in its first or collapsed configuration. In the illustrated embodiment, the sleeve 250 includes a contact portion or a contact surface 259. The contact portion or the contact surface 259 is an inner surface of the sleeve 250 and is configured to contact the second end portion 214 of the elongate member 210 to help retain or force the second end portion 214 of the elongate member 210 in its first or collapsed configuration.

In the illustrated embodiment, the sleeve 250 includes an enlarged portion 257 disposed at the first or proximal end portion 252 of the sleeve 250. The enlarged portion 257 is configured to be larger than the remaining length of the sleeve 250. In some embodiments, the enlarged portion 257 is configured to help prevent the sleeve 250 from being entirely disposed within the body of the patient. For example, in some embodiments, the enlarged portion 257 is configured to contact an other surface or outer portion of the body of the patient to help prevent the sleeve 250 from being entirely disposed within the body of the patient.

In the illustrated embodiment, the elongate member 210 has a length that is greater than a length of the sleeve 250. As best illustrated in FIG. 3A, the elongate member 210 has a length L1 along its longitudinal axis LA1 and the sleeve 250 has a length L2 along its longitudinal axis LA2. The length L1 is greater than the length L2.

In use, the medical device 200 may be inserted into a body of a patient (as schematically illustrated in FIG. 11). In some embodiments, the medical device 200 may be inserted into the body of the patient while the second end portion 214 of the elongate member 210 is in its first or collapsed configuration. For example, in some embodiments, the medical device 200 may be inserted into the body of the patient while the contact portion or contact surface 259 of the sleeve 250 is in contact with the second end portion 214 of the elongate member 210 to retain the second end portion 214 of the elongate member 210 in its first or collapsed configuration. In some embodiments, the medical device 200 may be inserted into the body of the patient while the second end portion 214 of the elongate member 210 is disposed within the lumen 256 of the sleeve 250.

In some embodiments, the medical device 200 may be inserted into the body of the patient such that the second or distal end portion 214 of the elongate member 210 is disposed within the body of the patient and the first or proximal end portion 212 of the elongate member 210 is disposed outside of the body of the patient (or extends from the body of the patient). As illustrated in FIG. 11, a distal end portion 202 of the medical device 200 extends from an outer surface OS of the body of the patient.

The second end portion 214 may then be moved from its first or collapsed configuration to its second or expanded configuration. For example, in some embodiments, the elongate member 210 is moved with respect to the sleeve 250 such that the contact portion or contact surface 259 of the sleeve 250 disengages or is removed from the second end portion 214 of the elongate member 210. For example, in the illustrated embodiment, the sleeve 250 may be moved in the direction of arrow M (as illustrated in FIG. 3A) to disengage the contact portion or the contact surface 259 from the second end portion 214 (i.e., remove the second end portion 214 from the lumen 256 of the sleeve 250).

The second end portion 214 of the elongate member 210 may then move to its second or expanded configuration. In some embodiments, the second end portion 214 of the elongate member 210 is biased to its second or expanded configuration and will move to such configuration in the absences of an external or retaining force.

In the illustrated embodiment, once the sleeve 250 is moved such that the second end portion 214 of the elongate member 210 extends from the sleeve 250 (as illustrated in FIG. 3A), the position of the elongate member 210 with respect to the sleeve 250 may be locked or fixed. In the illustrated embodiment, the elongate member 210 may be rotated in the direction of arrow N to lock or fix the elongate member 210 with respect to the sleeve 250. For example, in some embodiments, an inner surface 251 of the sleeve 250 may include a cam or otherwise uneven surface. As the elongate member 210 is rotated or twisted, the inner surface may frictionally couple the elongate member 210 to the sleeve 250. The elongate member 210 may be rotated in an opposite direction to disengage or unlock the elongate member 210 from the sleeve. In other embodiments, a different type of coupling mechanism may be used to removably couple or fix the elongate member 210 with respect to the sleeve 250. In some embodiments, the coupling mechanism used to removably couple or fix the elongate member 210 with respect to the sleeve 250 is a helical threaded screw type mechanism. For example, the elongate member 210 may be rotated with respect to the sleeve 250 to move the elongate member 210 linearly with respect to the sleeve 250.

In some embodiments, the second end portion 214 of the elongate member 210 is configured to retain or help retain the medical device 200 in place within the body of the patient. Specifically, as illustrated in FIG. 11, the second end portion 214 in its second or expanded configuration is configured to contact bodily tissue BT of the patient to retain or help retain the medical device 200 in place within the body of the patient.

In some embodiments, once the medical device 200 is disposed within the body of the patient, other medical devices may be inserted into the body of the patient though the lumen 216 defined by the elongate member 210. Accordingly, such other or secondary medical devices may be used to perform additional medical procedures once such device is disposed within the body of the patient.

In the illustrated embodiment, the proximal end portion 212 of the elongate member 210 includes a hub 230. The hub 230 defines a lumen 232. The lumen or opening 232 of the hub is in fluid communication with the lumen 216 of the elongate member 210. In the illustrated embodiment, the lumen or opening 232 of the hub 230 is tapered or funnel shaped. In other words, there is a portion of the opening or lumen that is larger or wider than another portion of the opening or lumen. In the illustrated embodiment, the lumen or opening of the hub 230 funnels down to the lumen 216 of the elongate member 210.

In some embodiments, the funnel shaped lumen 232 of the hub 230 may help funnel the secondary medical devices down to and guide them to the lumen 216 of the elongate member 210. For example, in the illustrated embodiment, an inner surface 234 of the hub 230 may guide secondary medical devices into the lumen 216 of the elongate member 210. Additionally, in some embodiments, the inner surface 234 may contact the secondary medical devices and help couple or retain the secondary medical devices in place once they are disposed within the lumen 216 of the elongate member 210. For example, in some embodiments, the inner surface 234 may frictionally retain or couple the secondary medical devices in place within the medical device 200. As best illustrated in FIG. 3B, in the illustrated embodiment, the hub 230 includes a lever 239. The lever 239 is configured to be moved to from a first position to a second position to contact the secondary medical device SMD to help couple the secondary medical device within the lumen 216 of the elongate member 210. In some embodiments, the lever 239 may be rotated or twisted to move into and out of engagement with the secondary medical device.

FIG. 12 is a flow chart of a method 400 according to an embodiment of the invention. At 410, a medical device is inserted into a body of a patient. At 420, the elongate member of the medical device is moved with respect to the sleeve of the medical device. The movement allows a portion of the elongate member to move from a collapsed configuration to an expanded configuration. Accordingly, in some embodiments, the expanded configuration of the elongate member helps secure or anchor the medical device within the body of the patient.

While certain features of the described implementations have been illustrated as described herein, many modifications, substitutions, changes and equivalents will now occur to those skilled in the art. It is, therefore, to be understood that the appended claims are intended to cover all such modifications and changes as fall within the scope of the embodiments.
