  • Patent number: 11969559
    Abstract: 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.

  • Publication number: 20230173228
    Abstract: Described are drainage catheter hub devices which seal the hub from leakage when connected to a catheter. The catheter hub includes a hub body having an aperture with a sealing element mounted therein and a fluid passageway that communicates with the aperture. The fluid passageway and sealing element are configured to receive a tension member. A lever arm attached to the hub body is operable to secure the position of the tension member in the sealing element in a locked position or allow movement of the tension member through the sealing element in an unlocked position. The lever arm is configured to engage and compress the sealing element to block fluid flow through the sealing element and the aperture when the lever arm is in any position. The hub body may include a centering tab to align the tension member along a longitudinal axis of the hub body.

  • Patent number: 11638807
    Abstract: An introducer apparatus includes an outer sleeve and an inner cannula received within the lumen of the outer sleeve. The outer sleeve has a profile such that at least a portion of the distal end of the outer sleeve tapers in the distal direction at an angle not exceeding about 2° relative to a longitudinal axis of the apparatus. The distal open end of the outer sleeve has a wall thickness not exceeding about 0.003 inch. The inner cannula includes a tapered distal end portion. The tapered distal portion of the inner cannula extends distal to the distal open end of the outer sleeve, such that a generally smooth diametrical transition is provided between the outer sleeve tapered portion and the open distal end of the inner cannula.

  • Patent number: 9629704
    Abstract: Loading systems for compressing and loading an implantable medical device into a device chamber of a medical device delivery system are described. The loading systems include an elongate holding chamber within which the intraluminal medical device is disposed. A plunger has one or more attached pushers adapted to axially advance the intraluminal medical device through an intermediate portion of the holding chamber that has a tapered surface, which compresses the intraluminal medical device over a dilator of a medical device delivery system that has been introduced through the distal end of the elongate holding chamber. The elongate holding chamber can be placed within an outer storage container with an appropriate seal to for storage of the intraluminal medical device within the loading system. Methods of preparing an intraluminal medical device for implantation in a patient and kits useful in such methods are also described.

  • Patent number: 9398946
    Abstract: An expandable and retrievable device for treatment of a stenotic lesion in a body vessel is disclosed. The device comprises a tubular portion including a proximal end and a distal end extending from the proximal end. The tubular portion has a lumen formed therethrough between the proximal and distal ends. The device further comprises an expandable member formed helically about the tubular portion. The expandable member is configured to helically close, defining a collapsed state for delivery of the device. The expandable member is configured to helically open, defining an expanded state for treatment of the stenotic lesion in the body vessel. The expandable member has at least one filter portion that helically extends from the tubular portion at a predetermined angle. This defines a proximally faced opening when the expandable member is in the expanded state.

  • Patent number: 9205244
    Abstract: A haemostatic valve device (10) comprises a disk valve (52a) having a valve body with a first surface facing in a first direction, a second surface facing in a second direction opposite the first direction, and an opening (58a) formed in the valve body for providing communication through the disk valve. In some examples, the disk valve comprises a nipple (60b), axially offset from the opening, extending outwardly and away from at least one of the first and second surfaces. The haemostatic valve device may further comprise a second disk valve (52b) and the nipple (60b) may be removably disposed within, and sealingly engage, an opening (58b) of the second disk valve.
