摘要： A lumenal element configured to transit a body lumen comprising a lumenal member (102) and an outer member (200) disposed over at least part of the lumenal member with a structural support (350), e.g. a mesh or stent, having a facing surface facing a surface of the lumenal member and wherein the facing surface includes at least one non-smooth surface portion, discontinuity, or non-uniformity, wherein the structural support is between the lumenal member and the outer member wherein the outer member is at least partly sealed to adjacent surfaces of the lumenal member sufficient to withstand fluid pressure within a space about the structural support, wherein the lumenal member has a first flexibility in the area of the structural support, and increasing the flexibility of the area of the structural support by moving at least a part of the outer member out of contact with the structural support. The flexibility of a lumenal element can be changed. Also disclosed a method of assembly of the lumenal element.

摘要： Devices for palliating gastrointestinal strictures using rapid exchange type enteral stent placement catheters. The catheter may include an inner member and an outer member, with the two members being slidable with respect to one another. In various device embodiments, a ramp for directing a guidewire out from within the catheter is provided using portions of the outer member or a shaped mandrel. The inner member may take a number of forms, including a tubular distal portion, a skived or integrally attached elongate midsection, and a proximal portion. A mandrel can be used in a portion proximal of the guidewire ramp, with the mandrel taking one of several disclosed forms.

摘要： The disclosure describes a reinforced catheter system, such as a wire, that includes an inner layer having an inner lumen configured to allow an object to slideably move within the inner lumen. The catheter system may include a reinforcement structure, having an outer coating, such as a polymer. The reinforcement structure may be coupled over the inner layer to thereby at least partially encapsulate the inner layer. The catheter system may include an outer surface coupled over the reinforcement structure and the inner layer to thereby encapsulate both the inner layer and the reinforcement structure. The outer coating of the reinforcement structure may be re-flowed to thereby bond the inner layer to the outer surface to thereby create a reinforced homogeneous structure.

摘要： A catheter hub for use with a medical device and a catheter, the hub includes a hub body defining a fluid passageway in communication with a first aperture. Optionally, the hub body defines a second aperture that intersects the first aperture. The hub body attaches to the catheter wherein the fluid passageway and the catheter are aligned for fluid flow therethrough. The first aperture extends from and communicates with the fluid passageway to an exterior surface of the hub body and the first aperture configured to receive the medical device. The second aperture extends from and communicates with the first aperture and the exterior surface. A sealing element is sized for and positioned in either the first or the second apertures. The sealing element is configured to receive the medical device and seal both of the first and the second apertures.

摘要： Provided are drainage systems that may include a drainage manifold and may be suitable for draining fluid from a tissue site. The drainage manifold may include a plurality of elongate members having a moveable end that may be adapted to configure the drainage manifold to treat a uniquely shaped tissue site. The drainage manifold may be coupled to a drainage tube with a transitional connector to provide a drainage system capable of distributing reduced pressure to the tissue site to enhance the drainage of fluids.

摘要： The present disclosure is directed to an over-the-needle (OTN) catheter assembly having a structural member configured therein. The OTN catheter assembly includes a catheter coaxially mounted onto a needle. In one embodiment, the structural member includes a coil insert that is embedded into an interior wall of the catheter, thereby preventing kinking of the catheter when being inserted within a patient. In another embodiment, the structural member may be a separate and removable coil insert that is inserted into the catheter after the OTN catheter assembly has been placed in a targeted site within the patient and the needle is removed. In a further embodiment, the structural member may be a separate and removable solid insert having a blunt distal end that is inserted into the catheter after the OTN catheter assembly has been placed in a targeted site within the patient and the needle is removed. Thus, the structural member is capable of advancing the catheter to one or more targeted sites within the patient, if desired, without causing further discomfort to the patient.

摘要： Some embodiments relate to a catheter system having a changeable or adjustable working length. The catheter system can comprise a proximal end, a distal end, and a first axial lumen configured to receive a guidewire formed through at least a portion of the catheter body. A first opening can be formed through a portion of the catheter body and be in communication with the first lumen. The sheath can be rotatable, axially movable, or otherwise changeable from at least a first position to a second position, wherein the sheath can substantially cover the first opening in the catheter body in the first position, and can substantially expose the first opening in the catheter body in the second position.
