[0002] none. Technical Field
[0003] The present invention relates to a lung access procedure, such as a lung biopsy, and more specifically to a guide cannula with a pleural access liner for use in crossing pleural layers. Background Technology
[0004] Pneumothorax is a problematic complication of lung biopsy, in which air or fluid is allowed to enter the pleural cavity due to puncture of the parietal and visceral pleura. Pneumothorax, especially that requiring chest tube placement, is a major concern for clinicians performing percutaneous lung biopsies and for patients undergoing the procedure. The incidence of pneumothorax in patients undergoing percutaneous lung biopsies has been reported to be 9–54%, with an average of approximately 15%. On average, 6.6% of all percutaneous lung biopsies result in pneumothorax requiring chest tube placement, leading to a median hospital stay of 2.7 days.
[0005] Factors that increase the risk of pneumothorax include increased patient age, obstructive lung disease, increased depth of the lesion, multiple pleural punctures, increased time the needle spends penetrating the pleura, and perforation of the fissure. Pneumothorax can occur during or immediately after surgery, which is why a CT scan of the area is usually performed after needle removal. Other less common complications of percutaneous lung biopsy include hemoptysis (coughing up blood), hemothorax (a type of pleural effusion in which blood accumulates in the pleural cavity), infection, and air embolism.
[0006] What is needed in the art is a guide cannula with a pleural proximity liner for use in penetrating the pleural layer, which helps prevent pneumothorax. Summary of the Invention
[0007] The present invention provides a guide cannula with a pleural proximity liner for use in penetrating the pleural layer, which helps to prevent pneumothorax.
[0008] In one embodiment, the invention relates to a guide cannula for use in penetrating the pleura, comprising an elongated tubular member and a pleural proximity liner. The elongated tubular member has a proximal end, a distal end, and sidewalls extending longitudinally between the proximal and distal ends. The sidewalls have an outer surface and an inner surface, wherein the inner surface defines a lumen. The pleural proximity liner is made of an expandable and bioabsorbable material that swells upon hydration. The pleural proximity liner has the shape of an elongated tube and has an elongated opening that surrounds an outer surface portion of the outer surface of the elongated tubular member.
[0009] In another embodiment, the invention relates to a guide cannula for use in penetrating the pleura. The guide cannula includes an elongated tubular member and a bioabsorbable member. The elongated tubular member has a proximal end, a distal end, and a sidewall extending longitudinally between the proximal and distal ends. The sidewall has an inner surface defining a lumen. The sidewall includes a first outer surface portion having a first diameter and a second outer surface portion having a second diameter smaller than the first diameter. The second outer surface portion of the sidewall defines an elongated external recess of the sidewall extending around the entire elongated tubular member. The bioabsorbable member is positioned within the elongated external recess of the sidewall of the tubular member. The bioabsorbable material is configured to expand upon contact with a fluid.
[0010] One advantage of the invention is that the pleura is close to the liner, which facilitates access through the pleural layer to help prevent pneumothorax before, during, and after lung biopsy.
[0011] Another advantage of the invention is that the pleural approach liner is made of an expandable and bioabsorbable material that is reabsorbed by the patient’s body over time as the tissue heals to close the biopsy approach opening. Attached Figure Description

[0023] Now refer to the attached diagram, and more specifically to... Figure 1-4 The diagram illustrates a pleural penetration system 10, which includes a guide cannula 12 for use in penetrating the pleura during lung access surgery, having a pleural access liner 14, and a core assembly 16. The guide cannula 12 and the core assembly 16 are arranged along a longitudinal axis 22 such that the guide cannula 12 and the core assembly 16 are coaxial.
[0024] The needle assembly 16 includes a needle 16-1 and a needle handle 16-2. The needle 16-1 has a puncture tip 16-3. The needle handle 16-2 is fixedly connected to the proximal portion of the needle 16-1. The term "fixedly connected" refers to a connection between two or more components, wherein the components are not easily separated from each other. For example, the fixed connection between the needle handle 16-2 and the needle 16-1 can be achieved, for example, by adhesive, welding, press fit, or threaded connection.
[0025] The guide tube 12 includes a handle body 18 and an elongated tubular member 20. The elongated tubular member 20 has a proximal end 20-1, a distal end 20-2, a distal portion 20-3, a lumen 20-4, and a sidewall 20-5. The sidewall 20-5 extends longitudinally between the proximal end 20-1 and the distal end 20-2, for example, along the entire length of the elongated tubular member 20. The sidewall 20-5 has an outer surface 20-6 and an inner surface 20-7, the inner surface surrounding and defining the lumen 20-4.
[0026] For example, at a position distal to the proximal end 20-1, the handle body 18 is fixedly connected to the elongated tubular member 20, wherein the lumen 20-4 passes through the handle body 18. In other words, the lumen 20-4 extends through the handle body 18 and extends from the proximal end 20-1 of the elongated tubular member 20 to the distal end 20-2 of the elongated tubular member 20, for example, extending along the entire length of the elongated tubular member 20.
[0027] In this embodiment, particularly referring to Figure 4 The outer surface 20-6 of the sidewall 20-5 of the elongated tubular member 20 includes a first outer surface portion 20-8 having a first diameter 24-1 and a second outer surface portion 20-9 having a second diameter 24-2 smaller than the first diameter 24-1, wherein the second outer surface portion 20-9 of the sidewall 20-5 defines an elongated recess 26 in the sidewall 20-5 that extends around the elongated tubular member 20. In this embodiment, the elongated recess 26 of the sidewall 20-5 extends around the entire elongated tubular member 20 and has a length 28. The length 28 of the elongated recess 26 may be completely or alternatively partially filled longitudinally by the pleural proximity liner 14. For example, in some embodiments, the length 28 of the elongated recess 26 may be in the range of 2 to 5 centimeters.
[0028] Also refer to Figure 5 and 6 In this embodiment, the pleura near the liner 14 is a bioabsorbable component, which is initially in a dehydrated state (see [link]). Figure 5 ), and it is configured to expand and swell upon contact with fluids, such as bodily fluids during lung-approach surgery (see Figure 6 (Refer to again) Figure 1-4 The pleural proximal liner 14 can be configured as an expandable and bioabsorbable elongated cylindrical layer connected to the outer surface 20-6 of the elongated tubular member 20, wherein the connection between the pleural proximal liner 14 and the outer surface 20-6 of the elongated tubular member 20 can be a friction fit.
[0029] In this embodiment, particularly referring to Figure 5 and 6The pleural adjoint liner 14 has a shape, for example, cylindrical, and includes an elongated tube 14-1 with an elongated opening 14-2. The elongated opening 14-2 (i.e., the elongated volume) is designed in terms of size and shape (e.g., having a circular cross-section) to frictionally fit around the outer surface 20-6 of the elongated tubular member 20. More specifically, also refer to... Figure 1-4 In this embodiment, the elongated opening 14-2 is designed in size and shape to surround the second outer surface portion 20-9 at the elongated outer recess 26 of the elongated tubular member 20, such that the pleural proximity liner 14 (bioabsorbable member) is located in and radially surrounds the elongated outer recess 26 of the sidewall 20-5 of the elongated tubular member 20. For example, the pleural proximity liner 14, as a bioabsorbable member, can extend radially around the entire elongated outer recess 26 of the sidewall 20-5 of the elongated tubular member 20, and can extend longitudinally along the entire length 28 of the elongated outer recess 26.
[0030] refer to Figure 1 For example, when the pleural proximal liner 14 is in an undeployed (e.g., dehydrated) state, such as before insertion into a patient, the pleural proximal liner 14 is initially a dehydrated bioabsorbable material extending radially around the outer surface 20-6 of the elongated tubular member 20, for example, fitting over the outer surface of the elongated tubular member so as to be carried by the elongated tubular member 20 for deployment. In the initial dehydrated state, the diameter of the pleural proximal liner 14 may be substantially equal to the first diameter 24-1 of the first outer surface portion 20-8 of the elongated tubular member 20 of the guide tube 12. The pleural proximal liner 14 may be made of at least one of collagen, silk fibroin, polyethylene glycol, hydroxypropyl methylcellulose, dehydrated gelatin, and starch. Thus, in some embodiments, the pleural proximal liner 14 may be made of polysaccharides.
[0031] In this embodiment, for example, the elongated tube 14-1 of the pleural proximal liner 14 may be pre-formed to include an elongated opening 14-2 and may be made of a foam material. During assembly, the elongated tubular member 20 is inserted through the elongated opening 14-2, such that the elongated tube 14-1 is in frictional contact with the outer surface 20-6 of the elongated tubular member 20, and more particularly with the second outer surface portion 20-9 in the elongated recess 26 of the elongated tubular member 20. The foam material may be made of or formulated to include at least one of collagen, silk fibroin, polyethylene glycol, hydroxypropyl methylcellulose, dehydrated gelatin, and starch (or other polysaccharides), which expands upon hydration. In some embodiments, the pre-formed elongated tube 14-1 forming the pleural proximal liner 14 may be a tube, for example, a braided fiber or an electrospun fiber.
[0032] In an alternative embodiment, for example, the pleural proximity liner 14 may be a powder coating attached to, for example, the outer surface 20-6 of the elongated tubular member 20 to form an elongated expandable cylindrical layer surrounding the outer surface 20-6 of the elongated tubular member 20. For example, the powder coating forming the pleural proximity liner 14 may be attached to a second outer surface portion 20-9 at an elongated recess 26 of the elongated tubular member 20 and applied radially around the elongated recess 26 of the sidewall 20-5 of the elongated tubular member 20. In other words, the powder coating attached to the outer surface 20-6 of the elongated tubular member 20 may extend around the entire elongated recess 26 of the sidewall 20-5 of the elongated tubular member 20.
[0033] In an embodiment of the powder coating, the powder coating forming the pleura near the bushing 14 is made of or made into at least one of collagen, silk fibroin, polyethylene glycol, hydroxypropyl methylcellulose, dehydrated gelatin and starch (or other polysaccharides), which expands upon hydration.
[0034] Refer again Figure 5 and 6 In some embodiments, it may be desirable to confirm the deployed position of the pleural proximity liner 14, which can be determined by imaging, such as X-ray imaging. Therefore, the pleural proximity liner 14 may optionally include a marking material or feature, such as a radiopaque material 30. The radiopaque material 30 may be, for example, a radiopaque substance (e.g., barium composition) or a metallic element (e.g., a stainless steel element).
[0035] Figure 7 A portion of the patient's chest wall 32 and lung 34 is depicted, and a pleural layer perforation system 10 is shown with a guide cannula 12 and the pleural approach liner 14 in an deployed state before hydration. To achieve... Figure 7 In the deployed state depicted, the core needle 16-1 is inserted through the lumen 20-4 of the guide sleeve 12 (see...). Figure 3 The puncture tip 16-3 of the core needle 16-1 protrudes from the distal end 20-2 of the elongated tubular member 20 of the guide cannula 12 (see...). Figure 1 , 2 and 7).
[0036] Refer again Figure 7The guide tube 16-1, in conjunction with the guide cannula 12 (carrying pleural proximal liner 14), is inserted into the patient to form a proximal opening 36 leading to the interior of the lung 34. Specifically, the proximal opening 36 is formed between adjacent ribs 38-1, 38-2 in the rib basket of the chest wall 32 and extends through the parietal pleura 40, pleural cavity 42, and visceral pleura 44 to provide access to the interior of the lung 34. Once the guide cannula 12 and pleural proximal liner 14 are inside the lung parenchyma, the positioning of the pleural proximal liner 14 through the parietal pleura 40, pleural cavity 42, and visceral pleura 44 can be confirmed, for example, by imaging. Fluid in and around the proximal opening 36 hydrates the pleural proximal liner 14, causing it to swell (see also...). Figure 6 And along the area between the parietal pleura 40 and the visceral pleura 44 near the opening 36, thereby helping to prevent pneumothorax.
[0037] Lung access procedures, such as lung biopsies, can be performed by removing the core needle 16-1 from the lumen 20-4 of the elongated tubular member 20 of the guide cannula 12 and then inserting a lung biopsy device, such as a biopsy probe, through the lumen 20-4 of the elongated tubular member 20 of the guide cannula 12 and into the lung. At the end of the lung access procedure, the lung biopsy device can be removed from the elongated tubular member 20 of the guide cannula 12. The elongated tubular member 20 of the guide cannula 12 can then be removed from the pleural access sleeve 14, such that the pleural access sleeve 14 remains in the access opening 36 to prevent air and fluid from entering the pleural cavity 42, thereby helping to prevent pneumothorax. During the removal of the elongated tubular member 20 from the pleural access sleeve 14, the pleural access sleeve 14 can be further inflated to close the elongated opening 14-2 of the pleural access sleeve 14.
[0038] In some embodiments, after the pleural proximal liner 14 expands during and after deployment, the coefficient of friction between the pleural proximal liner 14 and the patient's access opening 36 may exceed the coefficient of friction between the pleural proximal liner 14 and the elongated tubular member 20 of the guide cannula 12, such that when the elongated tubular member 20 of the guide cannula 12 retracts from the access opening 36, the pleural proximal liner 14 remains in the position within the access opening 36.
[0039] However, in some embodiments, it may be desirable to provide mechanical aids to assist in removing the elongated tubular member 20 of the guide cannula 12 from the pleural approach sleeve 14. For example, further reference... Figure 8 and 9Before deployment, a removal tool 46, for example in the form of an outer tube 46-1 having a lumen 46-2, can be positioned on the elongated tubular member 20 at a location proximal to the pleural approach liner 14, for example between the handle body 18 of the guide tube 12 and the elongated external recess 26 of the elongated tubular member 20 that carries the pleural approach liner 14.
[0040] After the pleural proximal liner 14 has unfolded and expanded within the patient, the removal tool 46 can be slidably advanced distally to contact the pleural proximal liner 14 (if not already in contact) to help maintain the position of the pleural proximal liner 14 as the elongated tubular member 20 is withdrawn proximally from the removal tool 46 and the pleural proximal liner 14. For example, the removal tool 46 can be grasped by one hand to maintain a fixed position of contact between the removal tool 46 and the pleural proximal liner 14, and the user can also grasp the handle body 18 of the guide cannula 12 with the other hand. The user then pulls the handle body 18 proximally to withdraw the elongated tubular member 20 proximally from the removal tool 46, thereby leaving the pleural proximal liner 14 in its position within the patient's proximal opening 36. The removal tool 46 can then be removed from the patient and discarded.
