The pliant member may also be configured to aid in incrementally deploying a vascular prosthesis.

Abstract: Fibrous materials and methods of manufacturing fibrous materials are disclosed. In particular, this application discloses methods of making and processing serially deposited fibrous structures, such as serially deposited fibrous mats. Serially deposited fibrous mats may be used in implantable medical devices with various characteristics and features. Serially deposited fibrous mats of various mat thickness, fiber size, porosity, pore size, and fiber density are disclosed. Additionally, serially deposited fibrous mats having various amounts of fiber structures (such as intersections, branches, and bundles) per unit area are also disclosed.

Abstract: Hub assemblies that include a first hub and a second hub can be used to selectively couple and uncouple medical device components to and from each other without rotating the first hub relative to the second hub. Some hub assemblies can include a dilator that includes a dilator hub and an introducer sheath that includes an introducer sheath hub.

Abstract: A syringe assembly or inflation device that includes a detachable housing. A pressure-sensing syringe assembly or inflation device can include both a syringe barrel and a housing that is coupled to the syringe barrel in a locked configuration. The inflation device can transition from the locked configuration to the unlocked configuration in which the housing is separable from the syringe barrel. Related methods are also disclosed.

Abstract: Transluminal stents are disclosed herein. In some embodiments stents within the scope of this disclosure may comprise a first flared end and second flared end. In some embodiments, a profile of each of the first flared end and the second flared end may circumscribe a portion of separate elliptical arcs. In some embodiments, the stents are formed from braided or woven wires having a constant pitch along a middle region and continuously varying pitches along the first flared end and the second flared end. Methods of manufacturing stents are disclosed herein. Methods of using stents are also disclosed herein.

Abstract: Syringe systems including barrels having lubricated portions and non-lubricated portions are provided. The non-lubricated portions may be configured to be loaded with injectable materials, such as embolic agents. The injectable materials may comprise polyvinyl alcohol. Also provided are methods of lubricating portions of barrels of syringe systems with lubricants including silicone or silicone-free lubricants.

Abstract: A filter configured to be disposed within the vasculature to capture or trap material within a body lumen is disclosed. The filter may be configured to be removable and may be configured to slice through ingrown or encapsulated tissue during removal. A filter deployment device or system which may be configured to deliver a filter or filters to a position within a body lumen, such as within the vasculature, is also disclosed. The filter deployment device may be configured to limit inadvertent decoupling of a filter. Also, the filter deployment device may be configured to retrieve a deployed filter.

Abstract: A convertible nephroureteral catheter is used in the treatment of urinary system complications, particularly on the need for a single surgically delivered device to treat patients who must be seen by an interventional radiologist (IR). In many current procedures, patients need to return to the operating room to remove a previously delivered nephroureteral catheter to exchange this catheter with a fully implanted ureteral stent delivered though the same access site at the flank. The present convertible nephroureteral catheter reduces the need to return for a second surgical procedure. Two weeks after initial implantation, the proximal portion of the convertible nephroureteral catheter extending out from the body may simply be removed. A simple action at the catheter hub allows this proximal portion to be removed, leaving behind the implanted ureteral stent within the patient's urinary system. Other medical procedures, devices, and technologies may benefit from the described convertible catheter.

Abstract: A multi-lumen catheter can be used to measure pressure at multiple locations within the vasculature. The multi-lumen catheter can include multiple segments, such as a proximal portion, an intermediate portion, and a distal portion. A segment of a multi-lumen catheter may differ from another segment of the same multi-lumen catheter in radiodensity, hardness, and/or some other characteristic. Some multi-lumen catheters are designed to permit measurements of pressure in different lumens.

Abstract: Radial artery compression devices with an inflatable chamber and a substantially rigid frame are disclosed. The inflatable chamber of the radial artery compression devices can be inflated and then deflated according to a predetermined protocol. Some substantially rigid frames can form a wall of the inflatable chamber. Some substantially rigid frames can include indicia to facilitate positioning of the inflatable chamber relative to a puncture site of a patient.

Abstract: A nephroureteral catheter is provided that comprises a detachable portion such that when the detachable portion is removed, the catheter converts into an internal stent. The catheter includes a tube with two retention features, a detachable portion, and an inner tube. The inner tube is removably insertable into both the tube and the detachable portion, and a wire extends through at least a portion of a lumen of the inner tube and through the tube, to keep the pieces attached. The wire may be removed to remove the inner tube and then the detachable portion from the tube. When the detachable portion is attached to the tube, the catheter is a nephroureteral catheter. When the detachable portion is removed from the tube, the catheter becomes a stent.
