Venous Access Port With Molded And/Or Radiopaque Indicia
A venous access port assembly having a base, a peripheral surface, and a septum. The base defines an interior reservoir. The peripheral surface includes integrally molded X-ray discernable indicia identifying that the assembly is rated for power injection. The X-ray discernable indicia may extend through a height of the peripheral surface from a top surface to a bottom surface thereof. According to one aspect, the peripheral surface may be formed from X-ray discernable material, and the X-ray discernable indicia may be formed from the X-ray discernable material, or they may be formed by voids in the X-ray discernable material. According to another aspect, the peripheral surface may be formed from a radiotransparent or radiolucent material and applied with a radiopaque agent, and the X-ray discernable indicia may be one or more voids in the radiopaque agent or may be portions of the peripheral surface applied with the radiopaque agent.
RETRIEVABLE ACCESS VALVE
Medical devices and methods for making and using medical devices are disclosed. An example medical device may include an access valve that may be retrieved after implantation. The access valve may include a frame having a lumen, a self-expandable member extending through the lumen, and an elastic membrane extending through the lumen and a second end of the frame to releasably seal the lumen. The access valve may releasably attach to a wall of a patient and releasably seal an opening through the wall. The access valve may be attached to the wall by placing the frame adjacent the wall, extending the self-expandable member through the opening in the wall, and expanding the self-expandable member such that the self-expandable member applies a first force against the wall and a second force opposite the first force against the frame to sandwich the wall between the self-expandable member and the frame.
Integrated Catheter Locking Mechanism for Port
Embodiments disclosed herein are directed to an integrated cathlock mechanism configured to engage an outer surface of a catheter to secure the catheter to a stem of a port, or similar medical device. The engagement structure can include a plurality of fins or an O-ring. The cathlock mechanism can include an engagement structure disposed annularly about the stem and configured to transition between an unlocked and locked configuration. The cathlock mechanism can be biased towards a locked configuration. A tab can selectively engage the cathlock mechanism and can maintain the cathlock mechanism in an unlocked configuration. Urging the catheter into the cathlock mechanism and onto the stem can engage the stem in an interference fit. A user can then remove the tab to transition the cathlock mechanism to the lock configuration.
IDENTIFICATION SYSTEM FOR INJECTABLE ACCESS PORTS
A vascular access port configured to be implanted subcutaneously comprising a housing; a septum affixed to the housing; an internal reservoir collectively defined by the septum and the housing; an outlet stem defining a lumen configured to be in fluid communication with the internal reservoir and having a retention feature on an outer surface of the outlet stem; a connecting element slidingly engageable over an outer surface of the distal end of the catheter positioned over the outlet stem; and one or more markers on the connecting element and discernable following subcutaneous implantation of the access port. The outlet stem is configured to receive a distal end of a catheter such that the distal end of the catheter is positioned over the retention feature of the outlet stem. Related systems and methods of use are described.
IMPROVED HEMODIALYSIS PORTS AND METHODS
Implantable graft-port systems, devices, and methods for establishing access to a fluid-filled internal body space of a patient including the patient's vascular system for blood treatments are described herein. A port device includes a substantially flat surface. The surface is oriented proximal to and substantially parallel with the patient's skin when the device is subcutaneously implanted. The port device includes a tapered seat disposed in a center of the surface and configured to receive a tip of an access tube. The tapered seat is configured to receive the tip of the access tube therethrough. A lid is configured to couple to the substantially flat surface of the port device and includes a guide configured to engage the tip of the access tube and to facilitate percutaneous introduction of the access tube toward the tapered seat irrespective of an introduction angle. The guide includes a continuous sequence of fluted features.
Medical device for detection of a leakage of fluid on a subject
A medical device for detecting a leakage of fluid on a subject includes a support, configured for being secured on the subject, and an optical sensor on the support. The support defines, in a region between the optical sensor and a lower face thereof, a detection surface that can be reached by leakage fluid. The optical sensor is arranged for detecting a leakage of fluid. The optical sensor has a sensor body with an emitter and a receiver of electromagnetic radiation. The support and the sensor body have mutual-coupling means, for retaining the sensor body on the support in such a way that a presence of leakage fluid can be detected via the optical sensor.
Medical Safety Needle Assemby
Medical safety needle assembly comprising a medical needle having a distal and a proximal end and a stem extending there between, the needle having a tip at its distal end, the proximal end of the needle being connectable to a fluid path, and the needle stem having a 80-90 bend, and a safety device comprising a base plate and a housing the base plate and the housing enclosing together a cavity, the safety device being slidably arranged on the needle stem distal from the bend, and the needle stem passing through a distal opening in the base plate and a proximal opening in the housing, the needle having an inserted position with the needle tip extending in distal direction from the base plate and a retracted position with the needle tip being in a position inside the cavity, characterized in that the housing consists of a first part attached to the base plate and a second part (32) attached by means of extendible attachment elements (33) to the first part, wherein the proximal opening is arranged in the second part (32) of the housing, and wherein the attachment elements (33) allow a movement of the second part (32) of the housing relative to the first part in the proximal direction of the needle stem between a first and a second position; the needle stem comprises a dead stop arranged distal from the proximal opening in the second part (32) of the housing that cannot pass through the opening.
Implantable dual reservoir access port
A dual reservoir access port includes a base having proximal and distal fluid reservoirs. The fluid reservoirs each comprise a bottom and a side wall. A dual prong outlet stem projects from a distal end of the base and comprises a first prong and a second prong. A first fluid channel extends through the first prong to the distal reservoir, and a second fluid channel extends through the second prong to the proximal fluid reservoir. A puncture shield is disposed between at least a portion of the second fluid channel and the bottom of the distal fluid reservoir. A needle-penetrable septum is disposed atop of each of the fluid reservoirs. A cap is placed over and around the port base compressing and sealing the septa against the base. A locking collar may be placed over a dual lumen catheter to lock the catheter to the dual prong outlet stem.

PORT FOR A CATHETER
A port (1) for a catheter comprises: a housing (10) having a base plate (12); a cavity (140) arranged in the housing (10) for receiving a fluid; a membrane (13) attached to the housing (10) and arranged on an opening (102) of the housing (10) for sealing the opening (102) such that the cavity (140) is enclosed in the housing (10) in a fluid-tight manner; and a connector (15) for connecting a catheter (2) to the housing (10) to provide a fluid connection between the cavity (140) and the catheter (2). The port (1) has an outer shape defined by the housing (10) and the membrane (13) attached to the housing (10). In addition at least one adapter piece (3, 4) is provided, the at least one adapter piece (3, 4) in a preassembly state being separate from the housing (10) and being attachable to the housing (10) to alter the outer shape of the port (1), wherein the port (1) is operational with or without the at least one adapter piece (3, 4) attached to the housing (10).
