Prosthetic device and method of using in breast augmentation and/or breast reconstruction

Номер: US20120004723A1

Автор: Enrico Mortarino, Gregory H. Altman

Принадлежит: Allergan Inc

A method of using a biocompatible surgical knitted, silk scaffold device in a breast augmentation or in a breast reconstruction cosmetic or surgical procedure such as single-stage or two-stage breast reconstruction. In an aspect of the invention, the silk scaffold employs a knit pattern that substantially prevents unraveling and preserves the stability of the mesh or scaffold device, especially when the mesh or scaffold device is cut. An example scaffold device employs a knitted mesh including at least two yarns laid in a knit direction and engaging each other to define a plurality of nodes. The at least two yarns include a first yarn and a second yarn extending between and forming loops about two nodes. The second yarn has a higher tension at the two nodes than the first yarn. The second yarn substantially prevents the first yarn from moving at the two nodes and substantially prevents the knitted mesh from unraveling at the nodes.

Capsules, emplacement apparatus, and associated methods for establishing a capsule within tissue are described herein. The emplacement apparatus may be catheter-based or implemented in a handheld unit. The emplacement apparatus serves to introduced an encapsulating membrane in a collapsed condition into the tissue, and then to expand the encapsulating membrane within the tissue into a capsule by injection of fill material into the encapsulating membrane. Other than being capable of injection through the emplacement apparatus, the fill material may be selected and formulated to achieve such mechanical and biological properties within the encapsulating membrane after injection as are desired to achieve the therapeutic effect sought for the patient. Mechanically, the fill material within the encapsulating membrane after injection may be a liquid, a semi-solid such as a gel, or a solid such as a cross-linked polymer. The fill material may or may not be sealed within the encapsulating membrane.

Принадлежит: Optonol Ltd

An implant includes a tube for permitting fluid flow. A flow controlling rod may be inserted within the tube passage. One or more holes around the circumference of the tube may be selectively permanently or temporarily occluded to give desired flow characteristics. A delivery device for implanting the implant may include a central bore in which a retractable wire is located. The retractable wire penetrates a tube passage of the implant. After the implant is in position in the eye, the retention wire is retracted out of the implant. In a method for manufacturing an implant, two tubes of different diameters are utilized. The smaller tube fits inside the longitudinal bore of the larger tube. When the tubes are cut, the smaller tube forms the tube of the implant and the remaining portions of the larger tube form the retention projection and/or disk of the implant.

An Accommodating Intraocular Lens (AIOL) is disclosed herein, that is comprised of a flexible optic and a flexible haptic rim that conforms to the human eye capsule. The spherical or custom shape of the optic is engineered to be maintained during accommodation through the mechanical/optic design of the implant and the interaction between the implant and the naturally occurring position and actuating forces applied through ciliary muscles/zonules/and capsule as the brain senses the need to increase the diopter change or magnification when an object of fixation approaches the eye. The axial relocation or position of the AIOL may also be further adjusted anatomically to further improve the affect needed to achieve improved accommodation.

Corneal inlays and masks and methods of improving vision of a patient with corneal inlays and masks are provided. Masks with an aperture can improve the vision of a patient, such as by increasing the depth of focus of an eye of a patient. For example, a mask can have an annular portion with a relatively low visible light transmission surrounding a relatively high transmission central portion, such as a clear lens or aperture. This provides an annular mask with a small aperture for light to pass through to the retina to increase depth of focus. The mask may also include nutrient transport structures that provide nutrient flow through mask to prevent nutrient depletion. These nutrient transport structures can be configured to concentrate nutrient transmission near a center region of the mask to provide more nutrient flow near the center region.

In one aspect, the present invention provides a method of designing an intraocular lens (IOL) to address variations of at least one ocular parameter in a population of patient eyes. The method can include establishing at least one eye model in which the ocular parameter can be varied over a range exhibited by the population. The eye model can be employed to evaluate a plurality of IOL designs in correcting visual acuity for eyes in the patient population. An IOL design that provides a best fit for visual performance over at least a portion of the parameter range can then be selected.

Pre-stressed haptic for accommodating intraocular lens

Номер: US20130030525A1

Автор: Daniel G. Brady, Edward P. Geraghty, Randall L. Woods, Timothy R. Bumbalough

Принадлежит: Abbott Medical Optics Inc

An intraocular lens is disclosed, with an optic that changes shape in response to a deforming force exerted by the zonules of the eye. A haptic supports the optic around its equator and couples the optic to the capsular bag of the eye. The haptic may be pre-stressed before the optic is placed within it. After such placement, the pre-stress may be relieved, and the haptic may produce stress in the optic. The pre-stress may produce a radial tension or a radial compression in the optic. Alternatively, once the optic is placed within the haptic, both may undergo a process that changes the size and/or shape of one with respect to the other, causing a stress within the optic. This process may produce a radial tension or a radial compression in the optic. The haptic may include an annular ring having outer and inner diameters that may depend on the stiffness of the haptic.

A engineered tissue implant comprising a perfusion chamber formed with a biocompatible flexible tubular member having a wall defining an internal fluid flow passage and a porous scaffold within the fluid flow passage of the tubular member, the porous scaffold arranged such that, in a presence of a perfusion fluid, the perfusion fluid will flow through the porous scaffold and be inhibited from flow between the porous scaffold and the wall of the tubular member. The engineered tissue implant may be understood as a transplantable cell construct or as an implantable bioreactor for cell growth both in vitro and/or in vivo. A method to provide tissue for reconstruction may comprise forming the engineered tissue implant containing a scaffold, introducing and seeding cells to the scaffold, introducing a perfusion fluid to the scaffold which flows through the fluid flow passage and scaffold, proliferating the cells within the scaffold and forming blood vessels within the scaffold. This may be followed by transplanting the engineered tissue implant in vivo where nutrition and oxygen are provided to support the preloaded cells.
