A foldable pressing-type balloon structure (10), comprising a balloon body (100) used for arrangement in the Tenon capsule and a drainage component (200) capable of being closed automatically. The balloon body (100) is formed with a balloon cavity used for supplying normal saline or air; the balloon body (100) has a planar first surface (110) and a curved second surface (120); the height of the balloon body (100) along the first surface (110) is 0.2-2.0 cm; the drainage component (200) is connected to the second surface (120) of the balloon body (100) and communicated with the balloon cavity. The foldable pressing-type balloon structure (10) is implanted under the Tenon capsule, and a break is sealed by pressing by filling the inside of the balloon body (100) with a medium. Compared with scleral buckles in the prior art, fixing with buckles is not required, and it is only necessary to fix the position of the drainage component (200) by suturing to prevent displacement, so that an incision in surgery is reduced; moreover, because fixing with buckles is not required, extraocular muscles will not be pulled, so that a patient does not feel uncomfortable after surgery. The surgical method is simple in operation, the difficulty is reduced, and the time required for surgery is shortened.

Surgical constructs, assemblies, and methods for tissue reinforcement with a reinforcement (reinforcing) material.

Disclosed herein are drug delivery punctal implants and methods of using the implants for the treatment of ocular disorders requiring targeted and controlled administration of a drug to an interior portion of the eye for reduction or prevention of symptoms of the disorder. The physical arrangement of drugs within the punctal plugs disclosed herein results, in several embodiments, in advantageous controlled delivery of one or more drugs to the eye of a patient.

A method includes forming a scaffold and seeding the scaffold with live cells; growing the cells in the scaffold; and 3D printing the cells into a living subject, where the cells continue to live in the living subject.

A device to be implanted in a subject's body to form an implant for replacing and/or increasing a volume of soft tissue, the device being of the type including a three-dimensional frame which defines an inner space in the frame. The frame is typically bio-absorbable and includes two side apertures forming a transverse passage for inserting a vascular pedicle. The device further has at least two bio-absorbable textile sheets that can be stacked on each other in the inner space of the frame.

A vascular filter system for deploying a vascular filter utilizes a plurality of tensors that extend radially outward from a deployment sheath. The ends of the tensors are coupled with an attachment ring of the vascular filter and a plurality of attachment barbs are coupled with the attachment ring for securing the filter to the vessel wall. A method for retrieving the vascular filter from the vessel utilizes a reverse curve catheter, a guidewire that extends therethrough and an intravascular snare. The guidewire is advanced around the filter and into the snare which secures the guidewire around the filter for retrieval. A vessel distention device utilizes one or more distention tensors having a distention feature on the extended end, such as a blunt tip, to press on the inside vessel wall. The distention tensors extend out radially from a sheath to press on the vessel wall.

Embodiments of the invention provide compositions including bio degradable polymers, medical implants fabricated from these compositions and methods of using such implants. Many embodiments provide medical implants comprising a first polymer backbone having a first rate of biodegradation and a second polymer backbone having a second rate of biodegradation faster than the first rate. In some embodiments, the second backbone is configured to be replaced by a natural tissue layer. The first backbone provides a scaffold for the implant while the second backbone degrades. This scaffold can enhance mechanical properties of the implant including various aspects of mechanical strength such as tensile, bending, hoop and yield strength; and elasticity. The scaffold also serves to maintain a minimum level of structural support of the implant during the period of degradation of the second backbone or for the entire life of the implant so that the implant does not mechanically fail.

A gastroesophageal reflux preventer and related methods are provided. A gastroesophageal reflux preventer is configured to be positioned around the exterior of a body organ and may include an elongate portion including a plurality of nodes positioned along at least a portion of the length of the elongate portion.

Implants and methods for augmentation of the disc space between two vertebral bodies to treat disease or abnormal pathology conditions in spinal applications. The implant includes a chain of biocompatible material suitable for insertion into a disc space between two adjacent vertebral bodies in a patient's spinal column, wherein the spinal disc space has a transverse plane. The chain comprises a plurality of adjacent bodies having a height configured to reside within the disc space between two adjacent vertebral bodies and a length configured to reside in the disc space between two adjacent vertebral bodies when the chain is curved in an orientation substantially along the transverse plane of the spinal disc space.

A medical device may include an implantable device for treating a body tissue structure. The implantable device may include a wire structure which may include a wave pattern. The wire structure may be elastic so as to provide a pressure around the body tissue structure such that the pressure may change with movement of the body tissue structure.
