These implants support newly lifted breast parenchyma, and/or a breast implant. The implants have mechanical properties sufficient to support a reconstructed breast, and allow the in-growth of tissue into the implant as it degrades. The implants have a strength retention profile allowing the support of the breast to be transitioned from the implant to regenerated host tissue, without significant loss of support. Three-dimensional implants for use in minimally invasive mastopexy/ breast reconstruction procedures are also described, that confer shape to a patient's breast. These implants are self-reinforced, can be temporarily deformed, implanted in a suitably dissected tissue plane, and resume their preformed three-dimensional shape. The implants are preferably made from poly-4-hydroxybutyrate (P4HB) and copolymers thereof. The implants have suture pullout strengths ...

Absorbable implants for plastic surgery

Номер: US0011439490B2
Принадлежит: Tepha, Inc.

Absorbable implants for breast surgery that conform to the breast parenchyma and surrounding chest wall have been developed. These implants support newly lifted breast parenchyma, and/or a breast implant. The implants have mechanical properties sufficient to support a reconstructed breast, and allow the in-growth of tissue into the implant as it degrades. The implants have a strength retention profile allowing the support of the breast to be transitioned from the implant to regenerated host tissue, without significant loss of support. Three-dimensional implants for use in minimally invasive mastopexy/breast reconstruction procedures are also described, that confer shape to a patient's breast. These implants are self-reinforced, can be temporarily deformed, implanted in a suitably dissected tissue plane, and resume their preformed three-dimensional shape. The implants are preferably made from poly-4-hydroxybutyrate (P4HB) and copolymers thereof. The implants have suture pullout strengths that can resist the mechanical loads exerted on the reconstructed breast.

ABSORBABLE IMPLANTS FOR PLASTIC SURGERY Absorbable implants for breast surgery that conform to the breast parenchyma and surrounding chest wall have been developed. These implants support newly lifted breast parenchyma, and/or a breast implant. The implants have mechanical properties sufficient to support a reconstructed breast, and allow the in-growth of tissue into the implant as it degrades. The implants have a strength retention profile allowing the support of the breast to be transitioned from the implant to regenerated host tissue, without significant loss of support. Three-dimensional implants for use in minimally invasive mastopexy/ breast reconstruction procedures are also described, that confer shape to a patient's breast. These implants are self reinforced, can be temporarily deformed, implanted in a suitably dissected tissue plane, and resume their preformed three-dimensional shape. The implants are preferably made from poly-4-hydroxybutyrate (P4HB) and copolymers thereof. The implants have suture pullout strengths that can resist the mechanical loads exerted on the reconstructed breast.

A method of forming a composite sheet that is made of a first sheet and a second sheet is disclosed. The first and second sheets are bonded to each other at a number of spaced apart discrete inter-sheet bond locations. The method involves mechanically deforming a precursor nonwoven web to form a first web with deformations therein. The deformations form protrusions that extend outward from the first surface of the first web and openings in the other surface of the web. The method involves feeding the first nonwoven web with the deformations therein into a bonding nip where portions of the first region of the first web outside of the deformations are bonded to the second web to form a base-bonded composite web.

Номер: WO2014152956A1
Принадлежит: ALTRIA CLIENT SERVICES INC.

A method of enrobing a product portion in polymer strands includes mounting at least one product portion on a holding device and passing the at least one product portion through a polymer enrobing zone. The polymer enrobing zone can include a flow of polymeric fibers produced by a polymer spray head. The polymer fibers can wraparound the at least one product portion to produce an enrobed product portion. The holding device can hold the at least one product portion by passing at least partially through the body of the product portion. At least a portion of the holding device is removed from the enrobed product portion. In some cases, the at least one product portion includes smokeless tobacco.
