Collapsible tube embodiments may be used to promote hemostasis at surgical sites or any other suitable location. In some cases, vascular closure device embodiments may include collapsible tube embodiments in order to promote hemostasis at a surgical site during a vascular closure procedure.

An assembly includes a prosthetic heart valve and a delivery apparatus for implanting the prosthetic heart valve within the native aortic valve of a patient. The prosthetic heart valve has a radially compressible and expandable metallic stent and a flexible valvular structure mounted within the stent. The delivery apparatus has a handle, a first shaft having a proximal end portion and a distal end portion, a second shaft extending co-axially through the first shaft and having a proximal end portion and a distal end portion, the proximal end portions of the first and second shafts extending distally from the handle, a valve cover coupled to the distal end portion of the first shaft, and a nose piece coupled to the distal end portion of the second shaft.

The invention relates to a valve used in medical procedures. More specifically the invention relates to an introducer sheath valve used in minimally invasive and conventional surgical procedures. The valve may accommodate a wide range of surgical implement diameters, shapes, and multiple implements without imposing the high frictional forces of known valves.

Embodiments of the present disclosure provide an introducer device for introducing a medical device into a patient's vasculature. In one embodiment, the introducer device comprises a housing, a distal sheath adapted to be inserted into a patient's vasculature with the housing positioned outside of the patient's vasculature, a hemostatic seal mounted within the housing, and a tube positioned within the housing and movable longitudinally relative to the hemostatic seal between a proximal position and a distal position. In the proximal position, a distal end of the tube is positioned proximal to the hemostatic seal with the hemostatic seal closed. In the distal position, the distal end of the tube extends through the hemostatic seal and permits the medical device to be inserted through the housing and into the patient's vasculature without contacting the hemostatic seal.

Sheath assembly for the insertion of a cord-shaped element (32, 105), comprising an introducer sheath (101) and an auxiliary sheath (104) for insertion into the introducer sheath (101) together with the cord-shaped element (32, 105), with first fastening means (106) for detachably fastening the auxiliary sheath to the introducer sheath, and with second fastening means (107) for detachably fastening the cord-shaped element to the auxiliary sheath, wherein the introducer sheath (101) has a first sheath housing (13, 114) and a distal tubular section (11, 41 a) that terminates in the first sheath housing, and a first flushing device (108), wherein the auxiliary sheath (104) has a second sheath inner chamber (111), a distal, tubular part (112) and a second flushing device (109).

A medical device for use with a catheter assembly including an elongated catheter coaxially disposed within a sheath is disclosed. The medical device includes a deformable tube having a proximal end, a distal end, an outer wall with an outer diameter, and an inner wall forming an axial lumen. The distal end attaches to the sheath, and the proximal end receives the catheter into the lumen. The medical device also includes a opposing paddles disposed against the outer wall, each of the opposing paddles having a generally planar lock region to be disposed against outer wall at the outer diameter, the lock surface tangential to the deformable tube.

This device is an inserting member fixing device to fix a linear inserting member to an insertion target, the inserting member fixing device comprising: a main body; a chuck portion; an inner sealing portion to be brought into close contact with an outer periphery of the inserting member; an inserting member supporting portion to support the inserting member; and a movement restricting portion to restrict movement of the inner sealing portion and the inserting member supporting portion. The inserting member supporting portion and the inner sealing portion are provided adjacent to each other in an axial direction of the inserting member, and a space is provided between the inserting member supporting portion and the inner sealing portion so that a main body-side end portion of the inserting member supporting portion is displaceable when the inserting member swings.

Hemostasis valves and methods for making and using hemostasis valves are disclosed. An example hemostasis valve may include a main body having a distal end region and a proximal end region. A first seal member may be disposed within the proximal end region of the main body. A plunger may be coupled to the proximal end region of the main body. The plunger may be designed to shift between a first position and a second position. A first locking member may be disposed along the proximal end region of the main body. A second locking member may be disposed along the plunger. The second locking member may be designed to engage the first locking member.

Devices, systems, and methods for sealing medical devices, particularly during intravascular access, are disclosed herein. Some aspects relate to a hemostatic valve for sealing a wide range of medical devices, such as catheters, wires, embolectomy systems. The valve can include an elongate member having a first end, a second end, and a central lumen extending therebetween. A reinforcement structure extends along at least a portion of the elongate member and is coupled to the elongate member. A shell defining a first aperture and a second aperture may be included, which first and second apertures can be fluidly coupled by the elongate member. A tensioning mechanism is coupled to the shell and to the elongate member, the tensioning mechanism can be moveable between a first configuration wherein the tensioning mechanism is collapsed and the central lumen is sealed and a second configuration wherein the central lumen is open.

Hemostasis valves and hemostasis valve systems are provided. A hemostasis valve can include a valve member, wherein the valve member includes a first sealable opening disposed through a first portion of the valve member and a second sealable opening disposed through a second portion of the valve member. The valve member may also include three or more sealable openings. A hemostasis valve system may include a hemostasis valve and another medical device. The hemostasis valve may be releasably coupleable to the other medical device.
