A low-profile access port for subcutaneous implantation within a patient. The access port can include a set of receiving cups which can be placed in fluid communication with a catheter. The set of receiving cups can provide a greater skin surface with which to access the port to avoid repeated penetrations at a single locus, such as during consecutive dialysis treatments. The access port can alternatively include needle penetrable arms or elongate chambers that also have a slim, low profile. The access port can include a needle guide to direct subsequent needle access to different insertion points to permit healing at the previous insertion points. The access port can be formed of a modular construction with a first conduit, a second conduit, and an outer shell. The outer shell can include a proximal portion and a distal portion. The access port can include a stem assembly and a locking member.

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.

The invention provides for ensuring proper transfer of a fluid to a medical device using a syringe by determining a position of a distal end of the needle relative to the medical device and/or a subject using a sensor. If the position of the distal end of the needle relative to a desired point of injection on a medical device and/or the subject is determined to be within predefined parameters transfer of a content of the syringe to the medical device takes place or may be inhibited by a lockout system.

Embodiments disclosed herein are directed to a port system including a body defining a reservoir and a port stem. One of the body or the stem can be formed of a shape memory material and can be transitionable between an expanded configuration and a collapsed configuration. One of the port body or the reservoir in the collapsed configuration can provide a reduced overall size or outer profile of the port for subcutaneous placement and/or between access events. The port can require a smaller incision site, required fewer stitches or no stitches at all, improving patient recovery times, patient comfort, reducing scarring and improving aesthetics. The port stem in collapsed configuration can be smaller than a catheter lumen diameter and can transition to an expanded configuration that is larger than a catheter lumen diameter facilitating a fluid tight seal therebetween.

Embodiments disclosed herein are directed to a port system including a body defining a reservoir and a stem. One of the body can include a lower housing and an upper housing slidably engaged therewith and be transitionable between an expanded configuration and a collapsed configuration. The port body in the collapsed configuration can define a smaller volume or outer profile than the port body in the expanded configuration. The reservoir in the collapsed configuration can define a smaller volume than the reservoir in the expanded configuration. A biasing member can bias the port to the expanded configuration. A latching mechanism can retain the port in one of the expanded configuration or the collapsed configuration. An actuator can transition latching mechanism between a locked position and an unlocked position. Subcutaneous placement of the port in the collapsed configuration can require a smaller incision site, fewer stitches and improved patient recovery times.

Embodiments disclosed herein are directed to a port system including a collapsible reservoir and associated methods thereof. The port can include a body defining a reservoir and formed of a compliant material. The port body can transition between an expanded configuration and a collapsed configuration. The port can further include a port stem or a base plate, formed of a rigid or needle impenetrable material. The base plate can be aligned with a floor of the reservoir to prevent an access needle from traversing the bottom surface of the reservoir. The port, or the reservoir, can transition to the collapsed configuration to provide a reduced overall size or outer profile for insertion and/or between access events. The port can require a smaller incision site, required fewer stitches or no stitches at all, improving patient recovery times, patient comfort, reducing scarring and improving aesthetics.

Embodiments are directed to a low profile, injectable port system and associated methods of use. The port can define a port lumen extending between an inlet and an outlet and can include a needle penetrable septum or valve structure. The port stem can couple with a lumen of a catheter and optionally include a cathlock. The diameter, cross-sectional area or shape of the port lumen can substantially equal that of the catheter lumen in a relaxed state. Further the port lumen can define a straight axis and can be aligned with an axis of the catheter lumen. As such, the port can reduce fluid flow resistance between the port and the catheter. The outer profile of the port can substantially equal that of the catheter outer profile. As such, placing the port subcutaneously can require a smaller incision site, improving recovery times and aesthetics.

Medical devices and methods for making and using medical devices are disclosed. An example medical device may include an access valve that may be retrieved after implantation. The access valve may include a frame having a lumen, a self-expandable member extending through the lumen, and an elastic membrane extending through the lumen and a second end of the frame to releasably seal the lumen. The access valve may releasably attach to a wall of a patient and releasably seal an opening through the wall. The access valve may be attached to the wall by placing the frame adjacent the wall, extending the self-expandable member through the opening in the wall, and expanding the self-expandable member such that the self-expandable member applies a first force against the wall and a second force opposite the first force against the frame to sandwich the wall between the self-expandable member and the frame.

According to embodiments of the present invention, a subcutaneous implant delivery apparatus is provided. The apparatus includes a receiving portion configured to receive a subcutaneous implantable device; and a stabilizing portion configured to cooperate with the receiving portion to hold the subcutaneous implantable device in a fixed position. The receiving portion and the stabilizing portion are movable relative to each other between a released configuration, wherein the receiving portion and the stabilizing portion are configured to move apart from each other to allow the receiving portion to be inserted under a skin layer, and a closed configuration, wherein the receiving portion and the stabilizing portion are configured to move toward each other to allow the subcutaneous implantable device to be held adjacent to the skin layer. According to further embodiments of the present invention, a method of delivering a subcutaneous implantable device for accessing a vascular site is also provided.

A medical device comprises a flexible member that can be adhesively attached to a housing of the medical device, allowing implantation of the medical device into a body through an incision of reduced size. The flexible member can be attached to the housing either before or after implantation into the body. The flexible member comprises suture locations, including a permeable membrane or a suture hole, for suturing the medical device to tissue of the body. The suture holes can be filled with a substance penetrable by a suture needle, to minimize tissue ingrowth before or after suturing.
