The present disclosure is directed to a method of facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein. The method may include providing an intravascular device having a distal portion and a longitudinal axis and inserting the intravascular device into the vascular lumen. The method may further include positioning the distal portion in the vascular wall, rotating the intravascular device about the longitudinal axis, and advancing the intravascular device within the vascular wall.

A catheter has a catheter tube made of plastic with a closed catheter tip. At least one passage opening is formed in a section of a sheath wall adjacent to the catheter tip. The passage opening merges into the outer sheath wall of the catheter tube via rounded edge regions. The result is a catheter whose insertion into a body cavity is facilitated.

A method is used to insert an implant within a lateral wall of a nose of a patient. The method includes forming an initial incision with a surface of the lateral wall of the nose. A stylet is advanced within the lateral wall of the nose, thereby creating a pocket within the lateral wall of the nose. The stylet is further advanced until an expanding body of the stylet is at least partially housed within the pocket of the lateral wall. The expanding body of the stylet is enlarged to thereby enlarge the pocket within the lateral wall. The implant is placed within the enlarged pocket of the lateral wall.

A wiggle catheter (a dilator) is disclosed to facilitate advancing catheters after puncturing a blood pathway, including without limitation navigation of noncompliant hardware through a diseased lumen. The wiggle catheter includes a proximal section, a distal section, and an intermediate section disposed between the proximal section and the distal section, the intermediate section may include a plurality of angulated kinks along the long axis of the catheter, the angulated kinks having substantially the same diameter at the outer edge of the kinks, said diameter of the outer edge of the kinks being substantially same as the inner diameter of an introducer sheath whereby the wiggle catheter may be positioned inside the introducer sheath with the outer edges of the kinks in close proximity to the inner surface of the introducer sheath. The wiggle catheter may also include a sinusoidal waveform like structure or a helical or spiral structure.

The present disclosure relates to a method and a device for treating heart failure by normalizing elevated blood pressure in the left and right atria of a heart of a mammal. The present disclosure includes methods for creating and maintaining an opening in the atrial septum. Tools for making an opening and enlarging the opening are also disclosed. Use of the techniques and tools described herein prolongs the patency of an intra-atrial pressure relief opening.

A catheter is provided including a first lumen and a second lumen. A first member is disposed for relative movement within the first lumen and defines a cavity, A second member is disposed for relative movement within the second lumen. The cavity of the first member is configured for disposal of the second member. The catheter may include an elongated tubular body that includes the first lumen and the second lumen. The first member may have a distal portion that extends beyond the distal end of the body. The distal portion may include the cavity. The cavity may be defined by a member lumen. The first and second members may include tubular stylettes. The second member may include a guidewire.

One aspect relates to a catheter system, a use of such catheter system and a manufacturing method for such catheter system. The catheter system includes an at least partially flexible catheter body, at least a ring electrode, and at least a strain gauge. The ring electrode surrounds at least a portion of the flexible catheter body. The strain gauge is allocated to the ring electrode and the strain gauge is configured to measure a deformation of the flexible catheter body at a position allocated to the ring electrode to detect a contact between the ring electrode and tissue.

A chest tube device with neurostimulation is provided, along with a method of electrically stimulating at least one of (i) one or more peripheral nerves and (ii) one or more nerve fibers of a thoracic region of a patient, to mitigate pain in patients undergoing chest tube implantation. The chest tube device includes a tubular member and an electro-analgesic region to provide neurostimulation to one or more peripheral nerves and/or nerve fibers of the thoracic region of the patient. The method includes electrically stimulating one or more peripheral nerves and/or nerve fibers of the thoracic region of the patient, and hyperpolarizing the one or more peripheral nerves and/or nerve fibers of the thoracic region to (i) reduce an amount of pain signals from being transmitted to the brain of the patient and/or (ii) prevent pain signals from being transmitted to the brain of the patient.

Disclosed is an angioplasty balloon catheter and method of use, said angioplasty balloon catheter includes an elongated tip end with physical characteristics nearly identical to a standard angiographic diagnostic catheter. The elongated tip end extends approximately between 2 cm to 75 cm beyond a distal end of a balloon, depending upon embodiments. The tip of the elongated tip end may be angled or straight depending upon embodiments and may or may not have a plurality of side holes in addition to an end hole depending on embodiments. The elongated tip end permits the angioplasty balloon catheter to tract more easily across tortuous or markedly angulated segments of a dialysis graft or fistula, minimizing complications that can result with currently available devices. If angulated, the elongated tip end also enables a user to selectively catheterize an artery without needing a separate diagnostic catheter to do so, and enable tracking and cornering across sharply angulated vessel segments. Whether with an angled or straight distal catheter portion, the angioplasty balloon catheter disclosed herein allows the user to perform angioplasty of an inflow segment of a dialysis graft or fistula and then perform post angioplasty angiographic imaging without the need to exchange the angioplasty balloon catheter for a diagnostic catheter, advance the balloon catheter into the native artery, or perform a blowback angiographic run, thereby improving safety and reducing procedure time.

A hemostatic device is disclosed. The hemostatic device according to an embodiment of the present invention includes: a balloon which is expanded by a fluid supplied therein; a blood discharge pipe which includes a blood inflow hole at one end and exposes the other end to a lower side of the balloon wherein a certain section of a lower side of the blood inflow hole is surrounded by the balloon; and a fluid flow pipe communicating with the inside of the balloon for supplying or discharging the fluid and extending to a lower side of the balloon. The balloon includes a plurality of protrusions that are formed to protrude outward when the balloon is expanded by the fluid.
