Certain aspects of the present disclosure provide to angle adjustment systems using one or more spring arrangements. In certain aspects, an angle adjustment system comprises a component and a first spring arrangement coupled to the component, wherein the first spring arrangement comprises at least three spring elements. Further, the first spring arrangement is configured to allow the component to rotate around a first axis of rotation and prevent a first translational movement of the component with respect to the first axis of rotation.

The present disclosure relates to a movable rack arm assembly including a cam housing, a circular gear, a rack arm, a cam, and a spring assembly for contoured non-linear force transfer.

Generally described herein are apparatus, systems and methods related to a pre-loaded septum insertable in an access port housing for increasing the control of the compression within the septum and the interference between the septum and the housing. For example, a pair of washers having mating portions may be positioned on respective sides of a rubber septum and bent such that the mating portions of one of the washer are interlocked with the mating portions of the other washer, the interlocked portions forming a tight ring about the septum and generating lateral compression on the septum, thereby 'loading' the septum. In addition, fluid seals made of a rubber material with lower durometer than the rubber septum may be used at the interface between the rubber septum and the housing to enhance the fluid sealing functionality while promoting the self-sealing features of the rubber septum.

A self-adjusting gastric band applies a substantially constant force to a patient's fundus in order to facilitate weight control. The self-adjusting gastric band is capable of automatically relaxing and contracting in response to changes in the patient's fundus or in response to a large bolus passing through the patient's fundus that is constricted by the gastric band. The self-adjusting gastric band is automatically adjustable without hydraulic fluid and without external physician intervention. The self-adjusting gastric band comprises a movable member and a biasing mechanism coupled to the movable member to facilitate applying the substantially constant force against the fundus as the fundus changes size, shape and/or position.

Self-adjusting mechanical gastric band

An implantable device used in a gastric band system includes an access port, a tube coupled to the access port, and a shielding device covering a portion of the tube. The shielding device is positioned adjacent to the access port and covers the end of the tube coupled to the access port. The shielding device is made from a puncture resistant material, to protect the tube from puncture by a misplaced syringe needle inserted by a physician.

Generally described herein are apparatus, systems and methods related to a mechanical interlock joint geometry for various components and joining of components thereby creating a reliable seal against fluid leaks that is resistant at typical pressures experienced when the components are implanted into a human body. Furthermore, the seal may be enhanced when a fluid pressure exerted inside the components is increased (e.g., from 1 to 10 psi).

Self-sealing fluid joint for use with a gastric band

Generally described herein are apparatus, systems and methods related to utilizing a guiding tip to connect two open ends of respective tubes of a gastric banding system. More particularly, one of these tubes may include a barbed element at or near the point of connection which makes it difficult to connect the two tubes as the barbed element may be larger than an opening to receive the barbed element. The guiding tip provides a solution to this problem by acting as an interface between the barbed element and the receiving tube. In this manner, the sealing functionality of the barbed element may be retained while improving the ease of inserting the barbed element into the receiving tube.

Tube connector with a guiding tip

Generally described herein are apparatus, systems and methods related to a stem insertable into the access port tubing for the prevention of fluid leaks. More particularly, the stem or stems may be larger than the interior diameter of the access port tubing thereby providing a fluid seal to keep the fluid within the access port tubing. However, these fluid seals might not be absolute and may still allow a certain degree of leakage. In one embodiment, by including barbs which further presses against the interior diameter of the access port tubing, the sealing of the fluid may be substantially improved. The stem itself, while impenetrable by a needle, may still allow for bend flexibility of the access port tubing by employing a ball and socket joint for connecting to a next stem. In this manner, fluid leak prevention is improved while retaining the mobility of the access port tubing.

Interior needle stick guard stems for tubes

The present invention provides a system for attaching a fluid access port to a patient. The system generally comprises an implantable access port with a bottom exit port and method for attaching an access port to a patient. In addition, a tube guard, flexible tube exit port, tissue guard, and porous coupling member are disclosed.

Implantable bottom exit port

The present invention provides a system for attaching a fluid access port to a patient. The system generally comprises an implantable access port and method for attaching an access port to a patient. In addition, a tube guard, tube shroud, tissue guard, porous coupling member and a prefabricated mesh member may be attached to the access port. For example, the prefabricated mesh may be coupled to the access port to facilitate securing the access port to the tissue of the patient.
