A catheter assembly and/or an introducer may include one or more features configured to guide a probe and/or a catheter distally through a septum. The catheter assembly may include a catheter adapter and the septum. The catheter adapter may include a distal end, a proximal end, and a lumen extending therebetween. In some embodiments, the septum may be disposed within the lumen. The septum may include a proximal surface that is tapered inwardly in a distal direction such that the proximal surface of the septum is configured to guide the probe and/or the catheter distally through the septum. The catheter assembly may be configured to receive an introducer, which may include an introducer element. A proximal end of the introducer element may include another proximal surface that is tapered inwardly in the distal direction such that the other proximal surface is configured to guide the probe or the catheter distally through the septum.

In alternative embodiments, the invention provides compositions, e.g., formulations, used for gastric, gastrointestinal and/or colonic treatments or lavage, e.g., orthostatic lavage, e.g., for inducing the purgation (e.g., cleansing) of a gastrointestinal (GI) tract, including a colon; and methods for making and using them. In alternative embodiments, compositions and methods of the invention are used for the stabilization, amelioration, treatment and/or prevention of constipation, for the treatment of abdominal pain, particularly non-specific abdominal pain, and diarrhea, including diarrhea caused by a drug side effect, a psychological condition, a disease or a condition such as Crohn's Disease, a poison, a toxin or an infection, e.g., a toxin-mediated travelers diarrhea, or C.difficile or the pseudo-membranous colitis associated with this infection. In alternative embodiments, the invention provides pharmaceuticals and products (articles) of manufacture for delivering these compositions and formulations to an individual, e.g., a human or an animal. The invention also provides devices for delivering a fecal material to a patient.

A gas-liquid delivery connector, a gas-liquid delivery connector pair, and a gas-liquid delivery device. The gas-liquid delivery connector comprises: a male connector (1) for connecting a catheter, wherein the male connector (1) is provided with a first connecting channel (11) in the axial direction thereof; and a female connector (2) for connecting a microcatheter, wherein the female connector (2) is provided with a second connecting channel (21) in the axial direction thereof. The female connector (2) is connected to the male connector (1) such that the second connecting channel (21) is in butt joint with and in communication with the first connecting channel (11), and the inner diameter of the second connecting channel (21) is the same as the inner diameter of the first connecting channel (11).

The present disclosure relates to a tube insert for a dialysis liquid line or a hydraulic tubing set, the tube insert including at least one housing; a first connection point for connecting a tube section of the hydraulic tubing set to the tube insert; a second connection point for connecting a second tube section of the hydraulic tubing set to the tube insert; a third connection point for connecting a fluid receptacle to the tube insert; a main line in fluid communication with the first connection point and with the second connection point; a secondary line in fluid communication with the third connection point; and a deflection element for deflecting the liquid, or parts thereof, flowing in the main line out of the flow direction and towards the secondary line.

Seals used within lead bores of implantable medical devices for creating a seal to implantable medical leads inserted into the lead bores include a cylinder that engages the lead body. The length of contact of the cylinder to the lead body is at least 0.010″ long while average contact pressure is no greater than (10 pounds per inch)/(contact length). Adequate electrical isolation is achieved, even when a debris particle is present between the inner cylinder and the lead body while insertion force remains acceptable.

A percutaneous fluid access apparatus includes a percutaneous fluid access device. The percutaneous fluid access device has a base portion including a subcutaneous portion and at least one port for connection to one or more fluid conduits within a body of a patient. A housing has at least one fluid channel and at least one seal for sealing the at least one fluid channel, and the housing is removably attachable to the base portion. The at least one fluid channel is in fluid communication with the at least one port when the housing is attached to the base portion.

A multi-tubing intravenous (IV) extension set may include an outlet tubing fluidly coupled to a primary multi-tubing connector at one end and fluidly coupled to a vascular device at an opposite end, and a primary inlet tubing having a proximal end with an adapter for connection to a syringe containing a priming or a medicinal fluid, and a distal end coupled to the primary multi-tubing connector. The IV extension set may further include at least one secondary inlet tubing with a proximal end having an adapter for receiving a medicinal fluid and a distal end selectively fluidly coupled to the primary multi-tubing connector. A slide clamp may be positioned on the outlet tubing to restrict flow between the proximal and distal ends of the outlet tubing and cause priming fluid flowing into the outlet tubing via the multi-tubing connector to reverse direction into the at least one secondary inlet tubing.

A medical device includes a base having a needle channel and a first surface configured to be secured to a patient's skin. An insertable member is configured to be secured to the base with a length portion of the insertable member extending out of the needle channel at the first surface, for insertion through the patient's skin at an insertion site. A septum extends across the needle channel. The septum has a body through which an insertion needle may be selectively extended to facilitate the subcutaneous insertion of the length portion of the insertable member. The septum provides a liquid seal across the needle channel. The needle channel and the septum provide a sealed volume in which a limited amount of blood or other fluid from the insertion site may be held.
