The present invention comprises a deformable, implantable subcutaneous port for anchoring a transcutaneous treatment component. A port body portion having a normal area port footprint is adapted by means of a port orifice for receiving and anchoring the transcutaneous treatment component beneath the point of entry into the physiology of a patient and for routing the transcutaneous treatment component. The port body portion is produced from a deformable material and has structure and/or composition that provides deformability characteristics of the port such that collapsing, folding, stretching, elongating and/or twisting the port body portion into a modified port shape having a reduced-size port profile enables removal of the port body portion from the physiology of a patient through a relatively small transcutaneous opening.

A method and apparatus are disclosed for a modified tip for a sheath assembly that provides enhanced radiopacity while maintaining the distal tip profile to maintain adequate tip stiffness and tip transition force. The disclosed method and apparatus provide a distal tip segment for a sheath assembly comprising a region of increased wall thickness along a portion or section of the distal tip segment, providing increased cross-sectional area there-along to provide enhanced radiopacity, and a distal most section of the distal tip segment having a reduced or minimal profile to provide an atraumatic tip while maintaining sufficient stiffness for crossability. The distal tip segment is operable to be coupled to a proximal shaft portion of the sheath assembly, to provide enhanced radiopacity while maintaining the distal tip profile to maintain adequate tip stiffness.

An improved method and device are provided for forming and/or maintaining a percutaneous access pathway. The device generally comprises an access pathway and attachment device. The provided assembly substantially reduces the possibility of iatrogenic infection while accessing and/or re-accessing a body space.

A method comprises positioning a medical appliance having a primary pressure sensor at or within a patient incision site and supplying an insufflation fluid to the patient cavity. The method further comprises measuring a pressure in the patient cavity by the primary pressure sensor and controlling the supply of insufflation fluid by an insufflator to the patient cavity based at least on the measured pressure. The method further comprises determining, by a processor associated with the insufflator, that the measured pressure may be inaccurate and, in response to determining that the measured pressure may be inaccurate, controlling, by the insufflator, the supply of the insufflation fluid to the patient cavity based at least on a pressure measured by a backup pressure sensor.

A first tubular medical device having a lumen through which a guidewire is insertable and over which the first tubular medical device may be guided to a target site within a patient. The proximal end of the guidewire may be extended into a lumen defined through a second medical device so the second medical device may be guided over the guidewire alongside the first tubular medical device to the target site. The guidewire may be extended into a distal opening in the first tubular medical device and out a side opening of the first tubular medical device to be available for guiding the second medical device alongside the first tubular medical device.

A sheath for producing a fully sealed access to the interior of a vessel of an animal or human body comprises a base sheath having a tubular body defining a pass-through channel. The base sheath is adapted to be inserted into the vessel through a vessel aperture. A wall of the tubular body of the base sheath has a through channel. This channel extends in the wall from the distal end towards the proximal end. The channel can be present separately from the pass-through channel of the base sheath or can form a sideways extension of the pass-through channel, at least at the distal end. Such through channel is adapted to conduct blood from the vessel to the proximal end of the sheath when the sheath has been inserted into a vessel.

A new process of manufacturing a hybrid cannula may include creating a first part with at least two components, overmolding at least two components of a second part to a channel in each component of the first part, and fixing the components of the first part together. The second part may include various types of features such as thick/thin dams, squirt membranes, and/or duck bill dams inside the hybrid cannula. Each dam may have any number, shape, orientation, and length of slits/openings. The slits/openings may allow passage of an instrument while the dam(s) may prevent fluid from passing through the hybrid cannula. A third part may optionally be overmolded to at least a portion of the first part, at least a portion of the second part, or both. The third part may provide an extension, a flange, or a combination thereof at a distal end of the hybrid cannula.

An example introducer is disclosed. An example introducer sheath includes a liner having a proximal portion, a distal portion and an axial slot extending along a portion thereof. The introducer sheath may also include a plurality of expandable members disposed adjacent at least a portion of the axial slot and a sheath disposed over at least a portion of the liner and the plurality of expandable members. Further, the introducer sheath is designed to shift between a first configuration and an expanded configuration

An introducer sheath may include a tubular member comprising an inner layer and an outer layer coaxially disposed about a central longitudinal axis of the introducer sheath, the tubular member being configured to shift between an unexpanded configuration to an expanded configuration. The inner layer may be circumferentially discontinuous along at least a portion of its length. At least a first portion of the inner layer may be configured to move circumferentially relative to the outer layer when shifting between the unexpanded and expanded configurations.

The present disclosure illustrates an introducer sheath with a partially annealed metal frame. The introducer sheaths described herein include a hub coupled to a shaft. The shaft comprises a braided wire frame with (i) an annealed distal portion that prevents the braided wire frame from unraveling at a distal end, and (ii) a second portion that is unannealed; a jacket encompassing the braided wire frame; and a liner forming an inner wall.
