Adapters for a connector assembly for percutaneous tubing are provided. A male adapter (FIG. 22a, 1000) includes a connector fitting (1002) proximate a first end, the connector fitting configured to join to a connector for a tubing system or device, and a male connector (656) proximate a second end. The male connector includes a plug end with a fluid lumen defined therethrough, the plug end having a circumferential groove defined therein to receive a locking extension of a female connector sized to be received within the circumferential groove of the plug end to allow the female connector to rotate relative to and maintain axial engagement with the male connector when the locking extension is received within the groove. An adapter having a female connector (FIG. 24, 1300) is also provided.

A luminal access device is provided that includes a luminal graft attached to a patient lumen. A percutaneous access device (PAD) is coupled to the luminal graft and adapted to stabilize a conduit in fluid communication with the luminal graft and an external medical device. A portion of said PAD adapted to be external to the patient and seal around said conduit. Infectious agent penetration at an insertion site of the PAD is reduced by providing a porous inner sleeve fluidly connected to a conduit. A vacuum or hydrodynamic source is fluidly connected to the conduit to create a fluid draw from the subject tissue through the inner sleeve to the conduit. The conduit is readily formed to have a bore and an outer conduit surface, the outer conduit surface being optionally nanotextured. The conduit bore is adapted to accommodate a medical appliance.

The present disclosure is directed to a medical port drainage assembly that includes a port component and a replaceable catheter. The port component includes a tube having a proximal end, a distal end, and tube walls defining a catheter access lumen. A head component is located on a proximal end of the tube and an assembly retention element is located on a distal end of the tube. The head component is deployed outside the patient's body and defines an opening to the catheter access lumen. The assembly retention element is deployed within a lumen of the patient's body. The port component includes a valve assembly which may be a single valve (e.g., a duckbill valve) or a system of valves. The port component also includes a connector for coupling and decoupling the replaceable catheter to the port component.

The present invention provides devices for creating an external percutaneous fluidic connections. In one embodiment, a needle is configured for extending through an endoscope. The needle includes a distal sharp tip and a lumen extending therethrough. The needle extends out of the endoscope within a body cavity to create an incision through a patient's skin. A safety cap is attached over the distal sharp tip without occluding the needle lumen. A wire is inserted through the needle lumen such that it extends from outside the body at the incision, through the body, and outside the body at the patient's mouth. After removing the needle and the endoscope from the body, a PEG device is coupled to the wire at the patient's mouth, and the PEG device is delivered through the upper GI tract and out through the incision.

Connector assembly (FIG. 4a) includes a shell (210), a connector body (230), and a plug (250). The shell (210) has a sidewall (212) defining an interior, a first shell end having a first opening (214) defined therein, and a second shell end having a second opening (216) defined therein, each of the first (214) and second openings (216) in communication with the interior to receive percutaneous tubing therethrough, the shell (210) further having an engagement portion. The connector body (230) has a first body end (234) and a second body end (236) with a tube lumen defined therethrough, the first body end (234) having a connector tip (237), the connector body (230) having an engaging portion to engage the engagement portion of the shell (210). The plug (250) has a first plug end and a second plug end with a fluid lumen defined therethrough, the first plug end having a plug tip (257) extending therefrom.

A cannula assembly having a retention member and a method of manufacture of the cannula assembly is provided. The cannula assembly includes a cannula and a sleeve disposed around the cannula from a proximal end to a distal end. The sleeve can include a balloon formed by a stretch blow molding process following local heating once advanced over the cannula. Once formed, the balloon can be conditioned to constrict against the cannula. A conditioning aid can be advanced over the balloon when it is still formable to constrict the balloon against the cannula.

Devices, methods, and kits are presented that allow for simplified stent placement and stent retention in a biological vessel other than a blood vessel, and especially biliary stent placement in an antegrade manner. The devices and methods advantageously allow for shortened imaging and stent placement time, and substantially improve tolerability and/or retention of the stent in the vessel, and in further beneficial aspects, contemplated stents form a composite fluid path to facilitate drainage of the vessel. Still further, the devices and methods presented herein reduce or even entirely eliminate partial deflation of the peritoneal space during imaging and stent placement and so prevent exposure of operating personnel to vented gases carrying harmful agents.

An internal bolster for use securing a medical device, such as a feeding tube, within a body of a patient is disclosed. In one embodiment, a feeding tube includes an internal bolster, comprising one or more bolster arms that each include a first end hingedly connected to a distal end of the medical device and a free second end. The bolster arms are selectively deployable between a first position wherein the bolster arms are substantially in-line with an axis of feeding tube, and a second position wherein the bolster arms are substantially deflected from the axis of the feeding tube to enable securement of the feeding tube within a stoma or other opening defined in the body. Various means for selectively moving the bolster arms between the first and second positions are disclosed. Related methods of use are also disclosed.

An implantable device for venous or peritoneal access including a housing including a void having distal a proximal openings; an insert for insertion through the proximal opening comprising a venous or peritoneal catheter; a valve element mounted in a cylindrical recess of the insert; an extracorporeal coupling member of which a terminal portion can be inserted into a proximal recess of the valve element; one or two conduits extending from the catheter to the proximal end of the coupling member via the valve element and the insert for providing fluid communication, which can be interrupted by rotating the coupling member. The coupling member can be extracted from the recess only in a state of interrupted communication.
