Port for a catheter

A port for a catheter includes a housing, a chamber arranged in the housing for receiving a medically active substance, a connecting piece for connecting the catheter to produce a flow connection between the chamber and the catheter, and at least one lever, mounted to be pivotable about a pivot axis and realized to allow the catheter to be fitted onto the connecting piece in a first pivot position and to hold the catheter in a clamping manner on the connecting piece in a second pivot position. The at least one lever has different first and second portions. The first portion carries a latching device for latching the at least one lever with the housing and/or with a first portion of a further lever in the second pivot position. The second portion has a clamping device for holding the catheter in the clamping manner in the second pivot position.

Intrauterine fetal growth restriction—the biochemical rationale of treatment modalities including extraperitoneal transamniotic fetal supplements
09555052 · 2017-01-31 ·

Intrauterine fetal growth restriction (IUGR) is an affliction of a disparaging spectrum, placental insufficiency being the major inciting pathology. The resultant fetal hypoglycemia is alleviated by intravenous hypertonic D-glucose 25-50% maternal supplements, by improving the V.sub.max of placental substrate transfer, as per Michaelis-Menten model. Fetal normoglycemia so restored in turn surprisingly improves fetal hypoxia, hypercapnia if any, lactic acidemia, acidosis, oliguria with/without oligohydromnios, hypertriglyceridemia, and the fetal nutrient, mineral and vitamin acquisition. The list being phenomenal can only convince an inquiring reader by a biochemical sojourn into the aquatic world of the fetus, herein described. Maternal carbohydrate predominant, essential amino acids/fatty acids rich IUGR-diet incorporating maximal amounts of vitamin and minerals are highly beneficial for attainable placental V.sub.max. Transamniotic isotonic D-glucose supplement via minimally invasive Suprapubic extraperitonial pelvic approach for amniotomy (Sumathi Paturu's technique) with a Subcutaneously Implanted Pregnancy Port (SIPP) catheter is the additional therapy advocated.

Surgical instrument that enables access to a region of interest

A surgical instrument may include a multi-lumen catheter configured to be inserted within the tissue. The multi-lumen catheter may include a first lumen that may enable a flow of a fluid, a second lumen that may receive a navigation probe that may facilitate an ability to locate the region of interest within the tissue, and an expandable membrane that may be situated toward a distal end of the first lumen to form an expandable cavity. The expandable cavity may be configured to expand or contract based on the flow of the fluid through the first lumen. The surgical instrument may include a fluid line, coupled to the first lumen, that may supply the fluid to the first lumen to enable the expandable cavity to expand or withdraw the fluid from the first lumen to enable the expandable cavity to contract.

The invention relates to an implantable valve (1) for a drainage system for discharging cerebrospinal fluid, comprising: a valve housing (10) extending along a valve axis (A), an inlet (2) and an outlet (3) as well as a valve housing (10) surrounding an interior space (4), a valve body assembly (600) arranged in the interior (4) and movably arranged in the interior space (4), a first valve seat (5), wherein the valve body assembly (600) is configured to abut the first valve seat (5) to close a flow connection between the inlet (2) and the interior space (4) of the valve housing (10), a second valve seat (7) which faces the first valve seat (5), wherein the valve body assembly (600) is configured to abut the second valve seat (7) to close a flow connection between the outlet (3) and the interior space (4) of the valve housing (10), and a spring device (800) arranged in the interior space (4) which exerts a spring force on the valve body assembly (600) in the direction of the first valve seat (5).

CATHETER INSERTION APPARATUS WITH CONTINUOUS VISIBLE FLASHBACK
20250269147 · 2025-08-28 ·

The present disclosure relates to a catheter insertion apparatus including a hollow needle body connected to a needle hub, and a catheter that removably fits over the needle body. The needle body has a sharp distal needle tip for piercing a blood vessel wall. An internal flow passage of the needle hub is in fluid communication with the hollow needle body. An elongated housing is connected to the needle hub and includes a lumen in fluid communication with the internal flow passage of the needle hub. An integrated guide assembly is slidably mounted to the housing and is operable to move between a retracted position and an extended position. A flashback chamber is operable to receive a continuous flow of blood before, during, and after movement of the guide assembly between its retracted and extended positions. A safety guard may provide protection from the sharp needle tip.

Medical system including two access ports

A system includes a first port comprising a first inlet, a first outlet, a first fluid pathway extending from the first inlet to the first outlet, a second inlet, a second outlet, and a second fluid pathway extending from the second inlet to the second outlet. The system further includes one or more CSF catheters having a first lumen, a first distal opening in fluid communication with the first lumen, a second lumen, and a second distal opening in fluid communication with the second lumen. The one or more CSF catheters are, or are configured to be, operatively coupled with the first implantable device such that the first lumen is in fluid communication with the first fluid pathway and the second lumen is in fluid communication with the second fluid pathway. At least the first distal opening is configured to be placed in the CSF-containing space. The system further includes a second port having a third inlet, a third outlet, and a third fluid pathway extending from the third inlet to the third outlet. The system also includes a port catheter configured to operatively couple the third fluid pathway to the second fluid pathway.

Blood Draw Device with Support Tube for Prevention of Kinking During Catheter Advancement

A blood draw device for advancing an extension catheter into an indwelling catheter includes an introducer housing, a kink-resistant support tube, a primary advancement member, and a secondary advancement member. The primary advancement member is movable relative to the housing to move the catheter from a first catheter position within the introducer to a second catheter position where a catheter distal end extends out past the indwelling catheter. The secondary advancement member is distal from the primary advancement member and is movable relative to the housing to move the support tube from a first tube position within the introducer to a second tube position where a tube distal end extends out past the indwelling catheter. When in the second tube position, the support tube is arranged coaxially about a portion of the catheter, to prevent kinking thereof as it advances from the first catheter position to the second catheter position.
