Description

[0001] priority

[0002] This application claims the benefit of priority to U.S. patent application No. 18 / 105,533, filed on February 3, 2023, which is incorporated by reference in its entirety into this application. Technical Field

[0003] The present invention relates to the field of medical devices, and more particularly to intraosseous ports. Background Art

[0004] Vascular access devices (VADs) are widely used to deliver a variety of substances, including fluids, drugs including chemotherapy, blood products, and total parenteral nutrition. Percutaneous vascular access devices include standard central venous catheters (CVCs), tunneled central venous catheters, and peripherally inserted central venous catheters (PICCs). These catheters pass through the skin, enter the vein, and terminate in a central venous location. Percutaneous VADs can be left in place at the insertion site for weeks or longer, so they need to be regularly flushed with saline and / or anticoagulant solutions to prevent thrombosis and occlusion. Implantable VADs are used for patients who need access for weeks to months. Implantable VADs typically have a metal or plastic port that is implanted in the subcutaneous tissue and anchored to the fascia tissue together with the catheter portion that enters the vein. Implantable VADs also need to be regularly flushed with an anticoagulant solution (usually concentrated heparin) to prevent thrombosis and occlusion.

[0005] Currently available VADs carry a significant risk (approximately 10%) of introducing infection into the bloodstream, which can lead to serious and costly complications such as bacteremia,45 sepsis, or even death. In addition, because the VAD is in constant contact with the bloodstream, the VAD requires regular flushing to remove stagnant blood and prevent thrombosis and occlusion. Even with regular flushing, occlusion occurs in approximately 30% of patients, requiring treatment with thrombolytic agents or device removal and reinsertion of a new device, which is costly, can interfere with patient care, and lead to complications.

[0006]

[0006] Therefore, there is a need for a vascular access device that enables the exchange of fluids with a patient, is easy to implant and access, and is less susceptible to occlusion and the various limitations outlined above. Utility Model Content

[0032] Figure 1 A partial front cross-sectional view of a first embodiment of an intraosseous port (IOP) 100 for a patient during a treatment period defined by a medical system (system) 70 is shown. IOP 100 is typically configured to, for example, be implanted in a patient, such as fully implanted in a patient. IOP 100 is typically further configured to, for example, enable access to a patient's bodily fluid, such as blood. In some embodiments, for example, system 70 may be configured to extract bodily fluid (e.g., blood) from a patient and deliver the bodily fluid back to the patient in a processed state according to the operation of system 70, such as a hemodialysis system. In other embodiments, system 70 may be configured to extract bodily fluid from a patient and deliver different liquids to the patient. In the illustrated embodiment, IOP 100 is configured to enable access to a body fluid in a bone (e.g., in the medullary cavity of a bone).

[0033] Figure 1 The IOP 100 is shown implanted in a patient 30 such that the IOP 100 is disposed completely beneath the skin 40. The IOP 100 includes a proximal portion 104 disposed between the lower surface 42 of the skin 40 and the bone 50. The IOP 100 is coupled to the bone 50 such that a distal portion 106 of the IOP 100 extends through a bone wall 51 of the bone 50. A distal end 107 of the IOP 100 is disposed, for example, within a cavity 52 (such as a medullary cavity) of the bone 50. In some embodiments, the IOP 100 may be configured such that a proximal end 108 of the IOP 100 is disposed adjacent to the lower surface 42 of the skin 40.

[0034] The IOP 100 includes a frame 110 that generally defines the structure of the IOP 100. The frame 110 can be formed, for example, of any rigid material suitable for implantation in the patient 30, such as stainless steel or plastic. The frame 110 defines a first cavity 121 that is fluidly coupled to a first lumen 131 to define a first flow path extending between a first lumen opening 121A at a proximal end 108 and a first lumen opening 131A at a distal end 107. Similarly, the frame 110 also defines a second cavity 122 that is fluidly coupled to a second lumen 132 to define a second flow path extending between a second lumen opening 122A at a proximal end 108 and a second lumen opening 132A at a distal end 107. In the illustrated embodiment, the first cavity 121 and the first lumen 131 are laterally positioned relative to the second cavity 122 and the second lumen 132 in a side-by-side relationship. In other embodiments, the first cavity 121 including the first lumen 131 and the second cavity 122 including the second lumen 132 can be positioned concentrically relative to each other.

[0035] The IOP 100 includes a first spacer 151A extending across the first cavity opening 121A and a second spacer 152A extending across the second cavity opening 122A. The first spacer 151A and the second spacer 152A define a seal over the first cavity opening 121A and the second cavity opening 122A, respectively. The first spacer 151A and the second spacer 152A are configured for puncture via the needles 81, 82 and reseal after the needles 81, 82 are removed. The first cavity 121 and the second cavity 122 are configured to receive the ends of the needles 81, 82 therein, respectively, to provide access to the body fluid 60 therein. The first spacer 151A and the second spacer 152A can be formed, for example, of any suitable spacer material configured for implantation in the body, such as EPDM, polytetrafluoroethylene, Dacron, silicon, or polyurethane. During use, the first and second spacers 151A, 152A may be punctured several times (eg, 5, 10, 20, 50, or more times) throughout the life of the IOP 100.

[0036] The first lumen 131 and the second lumen 132 and the first lumen opening 131A and the second lumen opening 132A can be specifically configured for safe passage of blood therethrough. By way of example, the diameters of the first lumen 131 and the second lumen 132 can be large enough to prevent damage (e.g., hemolysis) of blood passing therethrough at a flow rate of about 50 ml / min, 100 ml / min, 150 ml / min, or more, which may be due to, for example, increased shear rate and / or considerable negative pressure. Similarly, the first lumen opening 131A and the second lumen opening 132A can include smooth corners and edges to prevent damage to the blood.

[0037] The frame 110 includes an anchoring mechanism 160 configured to secure the IOP 100 to the bone 50. In the illustrated embodiment, the anchoring mechanism 160 includes external threads 161 that enable the IOP 100 to be screwed into the bone wall 51. As can be appreciated by one of ordinary skill in the art, other anchoring mechanisms suitable for securing the IOP 100 to the bone 50, such as barbs or adhesives, are also disclosed herein.

[0038] In some embodiments, during use, the IOP 100 can be oriented relative to the bone 50. For example, the first cavity 121 and the second cavity 122 can be oriented longitudinally relative to the bone 50. In this orientation, the IOP 100 can be oriented relative to the flow direction of the body fluid 60 in the cavity 52 so that one of the first lumen opening 131A or the second lumen opening 132A is positioned upstream of the other lumen opening in the first lumen opening 131A or the second lumen opening 132A. By way of example, in the illustrated embodiment, the first lumen opening 131A is positioned upstream of the second lumen opening 132A. This orientation can be advantageous when the body fluid 60 is extracted from the cavity 52 through the first lumen opening 131A and the body fluid 60 is returned to the cavity 52 via the second lumen opening 132A. This orientation can minimize the recirculation of the body fluid 60 through the system 70. During use, the system 70 may draw bodily fluid 60 (eg, blood) at a rate of about 50 ml / min, 100 ml / min, 150 ml / min, or greater and return bodily fluid 60 at a similar flow rate.

[0039] Some bones may be more suitable than others for a given patient treatment using the IOP 100. For example, some bones may have a higher blood flow rate through the cavity than other bones. Some embodiments of the IOP 100 may, for example, be specifically configured to couple with the humerus, such as the greater tuberosity of the humerus.

[0040] Figure 2 A partial front cross-sectional view of a second embodiment of an IOP 200 is shown, which in some respects may be similar to that of a second embodiment of an IOP 200. Figure 1 The components and functions of the IOP 100 described herein are similar. It should be understood that all of the illustrated embodiments may have similar features. Therefore, similar features are represented by similar reference numerals, with the leading numeral incremented to "2". For example, the frame in Figure 1 is designated as "110" in , and similar frames are Figure 2 Therefore, the above disclosures on features with similar identifiers may not be repeated in the following. Figure 1Specific features of the IOP and related components shown in the drawings may not be shown in the drawings or identified by reference numerals, or may not be discussed in detail in the subsequent written description. However, such features may clearly be the same or substantially the same as features depicted in other embodiments and / or described with respect to such embodiments. Therefore, the relevant description of such features also applies to the Figure 2 The characteristics of IOP. Figure 1 Any suitable combination of features and variations thereof may be used with the IOP and component descriptions shown in Figure 2 This mode of disclosure is also applicable to other embodiments depicted in the subsequent figures and described below.

[0041] Figure 2 An IOP 200 is shown implanted in a patient 30 such that the IOP 200 is disposed completely beneath the skin 40. The IOP 200 includes a proximal portion 204 disposed between the lower surface 42 of the skin 40 and the bone 50. The IOP 200 is coupled to the bone 50 such that a distal portion 206 of the IOP 200 extends through the bone wall 51. A distal end 207 of the IOP 200 is disposed within the cavity 52. ​​In some embodiments, the IOP 200 can be configured such that a proximal end 208 of the IOP 200 is disposed adjacent to the lower surface 42 of the skin 40.

[0042] The IOP 200 includes a frame 210 that generally defines the structure of the IOP 200. The frame 210 can be formed, for example, of any rigid material suitable for implantation in the patient 30, such as stainless steel or plastic. The frame 210 includes a first tubular member 212A and a second tubular member 212B. The first tubular member 212A defines a first lumen 221 fluidly coupled to a first lumen 231 to define a first flow path extending between a first lumen opening 221A at a proximal end 208 and a first lumen opening 231A at a distal end 207. Similarly, the second tubular member 212B defines a second lumen 222 fluidly coupled to a second lumen 232 to define a second flow path extending between a second lumen opening 222A at a proximal end 208 and a second lumen opening 232A at a distal end 207. The frame 210 also includes a connecting member 211 configured to couple the first tubular member 212A and the second tubular member 212B together. Each of the first tubular member 212A and the second tubular member 212B is rotatably coupled to the connecting member 211 , so that the first tubular member 212A and the second tubular member 212B can rotate relative to the connecting member 211 .

[0043] The IOP 200 includes a first spacer 251A extending across the first cavity opening 221A and a second spacer 252A extending across the second cavity opening 222A. The first spacer 251A and the second spacer 252A define a seal over the first cavity opening 221A and the second cavity opening 222A, respectively. The first spacer 251A and the second spacer 252A are configured for puncture via the needles 81, 82 and reseal after the needles 81, 82 are removed. The first cavity 221 and the second cavity 222 are configured to receive the ends of the needles 81, 82 therein, respectively, to provide access to the body fluid 60 therein. The first spacer 251A and the second spacer 252A can be formed, for example, of any suitable spacer material configured for implantation in the body, such as EPDM, polytetrafluoroethylene, Dacron, silicon, or polyurethane. During use, the first and second spacers 251A, 252A may be punctured several times (eg, 5, 10, 20, 50, or more times) throughout the life of the IOP 200.

[0044] Each tubular member 212A, 212B includes an anchoring mechanism 260 configured to secure the IOP 200 to the bone 50. In the illustrated embodiment, the anchoring mechanism 260 includes external threads 261 that enable the tubular members 212A, 212B to be individually screwed into the bone wall 51. As can be appreciated by one of ordinary skill in the art, other anchoring mechanisms suitable for securing the IOP 200 to the bone 50, such as barbs or adhesives, are also disclosed herein.

[0045] In some use cases, the IOP 200 can be oriented relative to the bone 50. For example, the first cavity 221 and the second cavity 222 can be oriented longitudinally relative to the bone 50. In this orientation, the IOP 200 can be oriented relative to the flow direction of the body fluid 60 in the cavity 52 so that one of the first lumen opening 231A or the second lumen opening 232A is positioned upstream of the other lumen opening in the first lumen opening 231A or the second lumen opening 232A. By way of example, in the illustrated embodiment, the first lumen opening 231A is positioned upstream of the second lumen opening 232A. This orientation can be advantageous when the body fluid 60 is extracted from the cavity 52 through the first lumen opening 231A and the body fluid 60 is returned to the patient via the second lumen opening 232A.

[0046] Furthermore, each tubular member 212A, 212B can be oriented relative to the direction of flow of the bodily fluid 60 within the cavity 52. Figure 2As shown, the first lumen opening 231A and the second lumen opening 232A can be oriented laterally relative to their respective tubular members 212A, 212B. For example, in the illustrated embodiment, the first lumen opening 231A faces upstream relative to the flow direction of the bodily fluid 60, and the second lumen opening 232A faces downstream relative to the flow direction of the bodily fluid 60. This orientation of the first lumen opening 231A and the second lumen opening 232A can enhance the treatment process by minimizing recirculation of the bodily fluid 60 through the system 70.

[0047] Figure 3 A partial front cross-sectional view of a third embodiment of an intraosseous port (IOP) 300 for use with a patient 30 during a procedure defined by a medical system (system) 70 is shown. The IOP 300 is typically configured to be implanted, such as fully implanted, within a patient, for example. The IOP 300 is typically further configured to enable access to a bodily fluid 60. Figure 3 An IOP 300 is shown implanted in a patient 30 such that the IOP 300 is disposed entirely beneath the skin 40. The IOP 300 includes a proximal portion 304 disposed between the lower surface 42 of the skin 40 and the bone 50. The IOP 300 is coupled to the bone 50 such that a distal portion 306 of the IOP 300 extends through the bone wall 51. A distal end 307 of the IOP 300 is disposed within the cavity 52.

[0048] The IOP 300 includes a frame 310 that generally defines the structure of the IOP 300. The frame 310 can be formed, for example, of any rigid material suitable for implantation in the patient 30, such as stainless steel or plastic. The frame 310 defines a first cavity 321 that is fluidly coupled to a first lumen 331 to define a first flow path extending between a first cavity opening 321A at a proximal end 308 and a first lumen opening 331A at a distal end 307. Similarly, the frame 310 also defines a second cavity 322 that is fluidly coupled to a second lumen 332 to define a second flow path extending between a second lumen opening 322A at a proximal end 308 and a second lumen opening 332A at a distal end 307. In the illustrated embodiment, the first cavity 321 and the first lumen 331 are laterally positioned relative to the second cavity 322 and the second lumen 332 in a side-by-side relationship. In other embodiments, at least a portion of the first lumen 331 and the second lumen 332 can be positioned concentrically relative to each other.

[0049] The IOP 300 includes a graft 350 extending between a first cavity opening 321A and a second cavity opening 322A, wherein the graft 350 defines a flow path between the first cavity 321 and the second cavity 322. The graft 350 is configured to be punctured via needles 81, 82 to provide access to the body fluid 60 therein. The graft 350 is further configured to reseal after the needles 81, 82 are removed. In some embodiments, the first cavity 321 and the second cavity 322 are configured to receive the ends of the needles 81, 82 therein, respectively. The graft 350 can be formed, for example, by any suitable graft material, such as polytetrafluoroethylene, dacron, silicon or polyurethane. During use, the graft 350 can be punctured several times (e.g., 5 times, 10 times, 20 times, 50 times or more) during the entire life of the IOP 300.

[0050] The frame 310 includes an anchoring mechanism 360 configured to secure the IOP 300 to the bone 50. In the illustrated embodiment, the anchoring mechanism 360 includes external threads 361 that enable the IOP 300 to be screwed into the bone wall 51.

[0051] Method 400 for treating a patient may include all or any subset of the following steps, actions or processes. Method 400 may include coupling an intraosseous port to a bone of the patient (frame 410). In some embodiments, coupling the intraosseous port to the bone includes implanting the intraosseous port subcutaneously in the patient. In some embodiments, coupling the intraosseous port to the bone includes penetrating the intraosseous port into the bone.
