Surgical template and delivery device
View Patent ↗The present disclosure provides devices and methods relating to surgical breast procedures. The devices can include a holder and backing to assist in positioning a biological material adjacent to a tissue expander or implant.
1. An implantable breast implant support and positioning device implantable within a tissue pocket in a breast, the device comprising:
a disc-shaped backing member,
a holding member formed of a stiff material shaped in a cup-like configuration comprising a proximal edge and a distal edge and a first side and a second side,
wherein the proximal edge comprises a convex portion curving away from the distal edge, and the distal edge comprises a convex portion curving away from the proximal edge,
wherein the convex portions of the proximal and distal edges extend an entire length of the holding member,
wherein the convex portion of the proximal edge has a first radius of curvature and the convex portion of the distal edge has a second radius of curvature, the first radius of curvature being different from the second radius of curvature,
wherein the distal edge of the holding member is configured to produce a desired contour,
wherein the distal edge of the holding member comprises multiple adjacent indentations formed along the convex portion of the distal edge,
wherein the multiple indentations are dimensioned to permit passage of a surgical fastener through at least one of the multiple indentations, and
wherein each of the multiple indentations comprises an elongated slit extending from the distal edge; and
at least one fastener connected to the holding member proximate to the proximal edge and configured to hold a sample of biocompatible material in apposition to the first side of the holding member prior to implantation of the sample of biocompatible material at an implantation site, and
a sheet-like sample of biocompatible material having a proximal edge, a distal edge, and a general shape complementary to the general shape of the holding member,
wherein the proximal edge of the sample of biocompatible material is detachably connected proximate to the proximal edge of the holding member and the backing member is detachably connected proximate to the distal edge of the holding member,
wherein the holding member is configured to be detached from the sample of biocompatible material after implantation of the sample of biocompatible material at the implantation site,
wherein the sample of biocompatible material comprises an acellular tissue matrix configured to be fastened to tissue at or proximate to an inframammary fold, and wherein the holding member is configured to hold the tissue matrix in apposition to the first side of the holding member.
2. The device of claim 1 , wherein the multiple indentations are formed along the entire convex portion of the distal edge.
3. The device of claim 1 , wherein each of the multiple indentations defines a rectangular form.
4. The device of claim 1 , wherein the distal edge of the holding member is configured to produce a desired contour of a portion of a breast.
5. The device of claim 1 , wherein the holding member is biconvex in shape.
