摘要:
A medical connector device (130) is described for attachment to an associated percutaneous fluid access device (100) having a plurality of ports (120). The connector device (130) comprises a needle holder (134) holding a plurality of hollow needles (182) that is retained within an axial alignment channel defined by the connector device (130). The needle holder (134) can thus be translated back and forth along the axial alignment channel. The connector device (130) is for use with a percutaneous fluid access device (100) having an extracorporeal portion (106), one or more ports (120) accessible from the extracorporeal portion and a septum (122) for sealing each port. The apparatus may be used for neurosurgery applications.

Described herein is a vascular access port device (300) which provides both blood monitoring and providing access to a vascular element (200) implanted within a hemodialysis patient. The device (300) comprises a body (310) connectable to the vascular element (300) at one end thereof, and a cartridge (330) mounted within the body (310). The cartridge (330) comprises an electrode set (375) arranged on a distal end (340a) of a septum (340) for sensing blood chemistry, associated electronics (360, 365, 370) for processing signals sensed by the electrode set (375), and inductive antenna arrangement (380, 400) for transmitting the processed signals to a remote location.
摘要:
Percutaneous access apparatus is described that includes a percutaneous fluid access device having an extracorporeal portion, one or more ports accessible from the extracorporeal portion and a septum for sealing each port. A connector device having one or more hollow needles is attachable to the percutaneous fluid access device. The apparatus also includes an attachment mechanism for attaching the connector device to the extracorporeal portion and an actuation mechanism that, after the connector device has been attached to the extracorporeal portion, can be used to drive the one or more hollow needles through the septum to establish fluid communication between the one or more hollow needles and the one or more ports. The apparatus may be used for neurosurgery applications.

Fluid storage apparatus for medical use is described that includes a length of tubing having a first end and a second end. A first sealable connector portion is provided at the first end and a second sealable connector portion is provided at the second end. The volume of fluid that can be stored within the apparatus is known and an infusate or therapeutic agent is contained within the apparatus. In this manner, a known volume of therapeutic agent can be infused to a patient. The use in neurosurgical applications is described.
摘要:
A medical apparatus and method of use for implanting a percutaneous catheter in a patient's body which catheter can be easily positioned, repositioned, and replaced. The apparatus includes an elongate sleeve comprising a wall surrounding an interior elongate passageway. The passageway extends from a sleeve proximal end to a sleeve distal end. The sleeve is intended to be percutaneously implanted through an incision in the patient's skin so that the sleeve distal end resides subcutaneously. The sleeve outer peripheral surface carries a layer of porous material intended to be placed just under the patient's outer skin layer in contact with the dermis to promote tissue ingrowth for anchoring the sleeve and forming an infection resistant barrier. The sleeve passageway is dimensioned to snugly accommodate the outer surface of catheter while permitting the catheter to slide relative to the sleeve. A sealing device is mounted around the catheter adjacent to the sleeve proximal end to prevent deleterious material from migrating into the patient's body along the catheter outer surface.

Adapters for utilizing a syringe or pen injector with a subcutaneous injection port to deliver a therapeutic substance through the injection port and methods of using the adapters are provided. A syringe adapter has a body having a first end and a second end. The first end of the body is configured to receive and engage the end of a syringe so that the cannula of the syringe is held at a fixed position with the respect to the adapter. The second end of the adapter configured to mate with a mating portion of the injection port. When the second end of the adapter engages the mating portion of the injection port, the adapter assures that the cannula of the syringe is properly aligned with the subcutaneous injection port and assures that the cannula penetrates the injection port to the proper depth. Adapters for use with pen style delivery systems are also disclosed. Additionally, an adapter to facilitate loading a syringe with a therapeutic substance from a vial is disclosed.

Implantierbare zylinderförmige Vorrichtung (1) für die Verbindung eines Schlauches ausserhalb des menschlichen oder tierischen Körpers mit einem innerhalb dieses Körpers gelegenen Schlauches (2), dadurch gekennzeichnet, dass um die zylinderförmige Vorrichtung (1) eine zur Hautoberfläche peripher abfallende Verankerungsplatte (13) angeordnet ist. Dadurch wird ermöglicht, dass im Falle eines Kippmoments des Portkörpers die Haut über die Verankerungsplatte abrollt.
摘要:
A cap (l8,l8 a ,l8 b ) for use with a percutaneous device (l0,l0 a ,l0 b ). The cap (l8,l8 a ,l8 b ) has a surface (2l, 2l a ,2l b ) carrying an adhesive for cutaneous contact in juxtaposition with the percutaneous device (l0,l0 a ,l0 b ) so that relative movement between the percutraneous device (l0,l0 a ,l0 b ) and the skin (l2,l2 a ,l2 b ) is inhibited.
摘要:
A multi-instrument sealing mechanism is provided. The multi-instrument sealing mechanism includes a cannula seal, a cannula cap, an instrument guide, an instrument seal, and door mechanisms in the instrument guide. The cannula seal can include a cross-slit seal. The cannula cap can capture the cannula seal between the instrument guide and the cannula. A door mechanism and instrument seal can be housed in the instrument guide.
