158 results about "Breast prostheses" patented technology

Breast prostheses are breast forms intended to simulate breasts. There are a number of materials and designs; although, the most common construction is silicone gel in a plastic skin. Off-the shelf breast prostheses come in a range of shapes and sizes, while customised breast prostheses are moulded to fit an individual's chest by taking an impression of both breasts and sculpting a mirror image. Pals Breast Forms consist of a lifelike gel which can be trimmed to fit with scissors, then sent back for customization. Fabrication of customised prostheses is typically done by an anaplastologist who makes somato prostheses. The areola and nipple may be replicated by being moulded into the breast form or a separate nipple prosthesis may be attached to the breast prosthesis. Both custom made and off-the shelf breast prostheses come in varieties that are designed to either be held in a pocket in a specially designed mastectomy bra or attached to the skin and worn with a standard bra.

All-barrier elastomeric gel-filled breast prosthesis

An elastomeric gel-filled prosthetic implant having a shell made of a single gel barrier layer. The barrier layer is formed of a homogeneous silicone elastomer capable of sterically retarding permeation of the silicone gel through the shell and having a bleed rate that is less than about 40% of the bleed rate of current shells which use a sandwiched construction with an internal barrier layer. Further, the barrier layer shell is made of a material that exhibits a wet strength that is comparable to or greater than current shells. The silicone elastomer may be a polydimethyl siloxane, and the substituted chemical group is a diphenyl group with a minimum mole percent of at least 13%. The implant may be designed for breast reconstruction or augmentation such that the shell is accordingly shaped. The shell wall thickness is at least 0.254 mm (0.010 inches), and desirably about 0.456 mm (0.018 inches). The implant shell may be made by dip-forming, spray-forming, or rotational molding. The exterior may be smooth or textured.

Breast prosthesis manufacturing method based on three-dimensional printing technology

The invention discloses a breast prosthesis manufacturing method based on the three-dimensional printing technology. The method comprises the steps that a tumor to be excised is analyzed and positioned according to breast medical image data of a patient before an operation, the shape, size and position of the excision part are determined, a three-dimensional digitalization tumor model is established, the radical treatment of the tumor and the demand for individualization overall beauty of the patient in the breast reestablishing process are comprehensively taken into consideration, a breast prosthesis three-dimensional model is optimized and designed according to the established tumor model and the breast shaping golden method, biologically-compatible materials conforming to the hand touch texture of the breast are selected, and the breast prosthesis is printed and formed through the biological three-dimensional printing technology. According to the breast prosthesis manufacturing method, the relation between the breast tumor and the peripheral tissue can be clearly displayed by analyzing and establishing the three-dimensional digitalization tumor model, and thus a doctor can conveniently determine the tumor excision range before the operation; the individualized accurate breast prosthesis can be provided for the patient quickly through the biological three-dimensional printing technology to improve the tumor radical treatment effect and the plastic surgery treatment effect, the living quality is improved, and the medical cost is lowered.
