A stabilisation system for securing a medical device such as a catheter to tissue, in particular skin, the stabilisation system comprising a main body having a first section and a second section displaceable relative to one another to translate the system between an undeployed state and a deployed state, each section including an array of microneedles extending from a tissue contacting surface of the body and which penetrate the skin in response to the above displacement, the stabilisation system further comprising a closure member displaceable between an open position exposing a retention zone on the body and a closed position at least partially occluding the retention zone, within which retention zone the catheter or other medical device may be captured.

Some embodiments of a medical device anchor system include an anchor device that secures a medical instrument (such as a catheter or the like) in place relative to a skin penetration point using subcutaneous anchors.

The present invention relates to a novel interchangeable lockable catheter having a cap, the cap locking onto a junction hub or base, and encasing at least one lumen proximally to the junction hub of a multi-lumen catheter, PICC line and the like. The interchangeable lockable catheter's cap and base may be made of more than one piece, and provide a locking mechanism sufficient to deter tampering, while providing a low profile, comfortable, sanitary, and efficient means of closing off lumens for patients leaving the treatment area.

An occlusion catheter system includes an inflation catheter member and an occlusion balloon. The proximal and distal balloon ends are connected to the inflation catheter between the proximal and distal catheter ends. A distal pressure sensor is attached to the inflation catheter member between the proximal balloon end and the atraumatic tip. An inflatable spine is connected to the inflation catheter. The proximal spine end is connected to the inflation catheter near the proximal balloon end and the distal spine end is connected to the inflation catheter near the distal balloon end. The occlusion balloon and the inflatable spine are configured to define blood flow channels with the internal surface and the external balloon surface when the occlusion catheter system is at least partially positioned in the vessel and the occlusion balloon and the inflatable spine are in a partially inflated configuration.

The Peritoneal Conduit is a medical device composed of tubing with an integrated collar made of a flexible and non-absorbable material for surgical implantation to create a conduit for passage of a catheter between two body cavities. The Peritoneal Conduit has a hollow center that spans from one end (shorter proximal portion) to the other end (longer distal portion). The catheter that will be being placed through the Peritoneal Conduit will enter into the proximal portion and will pass through the hollow center of the Peritoneal Conduit to emerge from the distal portion. The catheter is then secured to the Peritoneal Conduit using one suture that is tied around the groove in the proximal portion of the Peritoneal Conduit. The Peritoneal Conduit itself is secured in placed using two sutures that are placed through the integrated collar at the junction of the proximal and distal portions of the Peritoneal Conduit.

Some embodiments of a medical system include a subcutaneous anchor device that extends outwardly from side wall of an intravenous cannula so as to secure the intravenous cannula in a position relative to a skin penetration point.

The present adjustable-length dual-lumen hemodialysis catheter can eliminate the need to stock various lengths of hemodialysis catheters and can provide a hemodialysis catheter, which can be trimmed to various lengths in order to precisely accommodate patients of various shapes and sizes. Specifically, the present adjustable-length dual-lumen hemodialysis catheter can comprise a cuff ring assembly, which can be secured at selected locations along the trailing limbs of the catheter allowing the cuff ring assembly to be installed in a location chosen to precisely fit a particular patient.

An elongated catheter includes a tissue-engaging device configured to be urged to move and contact a first surface of the first biological wall. The tissue-engaging device extends from the distal catheter section. The tissue-engaging device is configured to be urged to puncture through the first biological wall. The tissue-engaging device is also configured to be urged to contact the first biological wall without impinging the second biological wall, after the tissue-engaging device has punctured through the first biological wall.

Apparatus and methods for placement of electrodes into selected tissue, such as the septal wall separating the left and right ventricles, with, in some cases, access to the septal wall from the right ventricle. Torque sleeves may be used to provide for rotation as needed.

The disclosure relates to the area of medicine and surgery, in particular it pertains to a drainage catheter (100) that comprises a high capacity drain comprising a radiological guide (110a) with a suction mesh (110b), a safety control opening/closing system (160), an internal pneumatic clamping system (140) and/or an external adhesive skin protection system (150). A reservoir for the administration of local anesthetics and antibiotics may be additionally provided. The disclosed catheter system optimizes flow surface, facilitates procedures for handling and removal of drainage, reduces the risk of occlusions, pain, injuries and infections of the surrounding skin and maintains sufficient structural strength to prevent collapses, among others.
