The present disclosure includes catheter systems and methods for treatment of occlusions, including coronary artery chronic total occlusions. The catheter system comprises a catheter coupled to a control system with a distal end inserted into a patient and proximal to a location within a blood vessel with an occlusion. The catheter comprises a flexible outer sheath surrounding a housing with a plurality of lumens to perform various functions to penetrate occlusions.

A device for implanting a heart prosthesis including a central body, a containment portion having one or more sub-components, and a release device for the central body capable of being inserted into a catheter. A device for assisting the connection operation between the central body and the sub-components of the containment portion includes an assembly of catheters, of which there are at least two catheters for each sub-component of the containment portion, the catheters being joined to each other over a portion thereof and having at least one free end for each catheter.

A percutaneous transluminal angioplasty device includes a catheter defining one or more lumens. A filter is coupled to the catheter adjacent a distal end of the catheter, and the filter is movable between an unexpanded and expanded configuration via a filter activation wire that extends through a lumen. An expandable balloon is coupled to the catheter proximally of the filter, and a stent is disposed over at least a portion of the balloon. To deploy the stent to a target site, the filter is first moved into its expanded position via the filter activation wire. Then, the stent is expanded, and the balloon is inflated to expand the stent further radially. The balloon is then deflated, the filter is contracted, and the catheter, balloon, and filter are removed from the body.

A catheter for percutaneous cardiopulmonary support has a lumen through which blood flows to a living body. The catheter comprises a catheter tube including a tubular reinforcing body including a plurality of wires braided into a mesh shape and a resin layer provided so as to cover the reinforcing body. A plurality of side holes are formed at a distal end of the catheter tube to communicate the lumen with the outside of the catheter tube. The side holes allow the blood flowing through the lumen to flow out in a direction intersecting an axial direction of the catheter tube when the catheter tube is indwelled. The plurality of side holes preferably may be spirally arranged in a circumferential direction of the tube.

The wound drainage apparatus for drug-assisted removal of bodily fluids includes a double-lumen tubing member connected to a customizable branched tubing member for placement in a wound cavity. A perforated inner tube connected to an anticoagulant drug delivery pump and a solid outer tube connected to a fluid drainage vacuum make up the double-lumen tubing member. The branched tubing member includes a plurality of secondary wound cavity tubes branching away from a primary wound cavity tube. The apparatus disclosed herein improves upon current drainage systems by preventing occlusions produced by blood clots forming in fluid drainage tubes.

A dual-lumen injection catheter is equipped with a distal balloon featuring one or more fenestration or openings on the distal portion thereof. This allows injection of contrast agent in parallel to the injection of embolic agent and better control over the delivery of the therapeutic agent for cancer treatments, bleeding or other purposes.

A system for aspirating thrombus and delivering an agent includes an aspiration catheter having a supply lumen having a proximal end, a distal end, and a wall, and an aspiration lumen having a proximal end, an open distal end, and an interior wall surface adjacent the open distal end, and at least one orifice at or adjacent the distal end of the supply lumen, in fluid communication with the aspiration lumen and located proximally of the open distal end of the aspiration lumen, wherein the at least one orifice is configured to create a spray pattern that is caused to impinge on the interior wall surface of the aspiration lumen such that the spray pattern upon impinging on the interior wall surface is caused to transform into at least a substantially distally-oriented flow capable of exiting the open distal end of the aspiration lumen.

Rapidly insertable central catheters (“RICCs”), introducers, and insertion devices including combinations and methods thereof are disclosed. For example, a RICC system can include an introducer and a RICC insertion assembly including a RICC assembly disposed in a RICC insertion device. The RICC assembly can include a RICC, an access guidewire, and a splittable casing over a catheter tube of the RICC and the access guidewire forming a longitudinal composite. The RICC insertion device can include a frame and a nose cover forming a split channel that splits away from a through channel of a nose of the frame. The RICC insertion device can be configured for advancing the RICC assembly by rolling the longitudinal composite across roller wheels disposed in the frame. The through channel can be configured for advancing the catheter tube therethrough while the split channel can be configured for both splitting and passing the splittable casing therethrough.

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.

Provided is an endoscope system including an elongated tube with one or more channels extending in a longitudinal direction along the elongated tube. The channels allow inserting of a viewing device for obtaining images from the distal end, inserting of surgical instruments to operate at the distal end, or passing of materials such as air or water. The channel for inserting the viewing device is enclosed or has a cover at the distal end of the elongated tube, such that the viewing device has no direct contact of body tissues, thereby eliminating the need for sterilization. Also provided is a safe and economical method for conducting endoscopy involving one-time use of a tube to keep the viewing device from directly contacting the body tissues.
