Abstract: 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.

Abstract: Disclosed herein is a combined introducer and expandable sheath having an inner member and an outer elastomeric jacket. The inner member has radially folded tapered segments in an unexpanded state that are mechanically unfolded and moved toward the inner wall of the elastomeric jacket by a medical device moving through the lumen of the inner member. The compressive outer elastomeric jacket returns the expanded inner member back to the radially folded, unexpanded state once the medical device has passed through the expanded lumen of the inner member. The structure can include a distal region that tapers to a rounded tip. The proximal region also tapers to mate with a hemostasis value housing.

Abstract: An anchoring for heart valve prostheses includes a stent framework, for attaching heart valve leaflets to an inner side, and compartmentalization clips, connected with the stent framework at a first end region and having a free second end region. The anchoring exhibits a primary form and reversibly transformable into a delivery form for the minimally invasive introduction into the body of the patient by elastic deformation and/or compression of certain regions or elements. The compartmentalization clips are arcuately shaped between the first and second end regions in the primary form and are elastically foldable such that the compartmentalization clips extend in a flat manner between the first and second end regions in the delivery form. The anchoring has a separation structure connected with the stent framework and the compartmentalization clips to separate the areas of the native leaflets to be treated from the bloodstream when the anchoring implanted.

Abstract: An airway support device of the present disclosure can be attached to tracheal and/or bronchial cartilage on opposing sides of a tracheal and/or bronchial wall to pull the tracheal and/or bronchial cartilages toward each other to reconstruct and/or reshape to a normal anatomy across the membranous tracheal and/or bronchial wall and thus relieving tension across the tracheal and/or bronchial wall. The airway support device can include at least two longitudinal strips that extend longitudinally along and are attached (e.g., sutured) to the trachea and/or bronchus on opposite sides of the tracheal and/or bronchial wall. Pairs of lateral strips extending from each of the longitudinal strips can be attached to each other under tension. The tracheal and/or bronchial wall can be attached (e.g., sutured) to the lateral strips to open the airway of the trachea and/or bronchus.

Abstract: A prosthetic valve delivery catheter and device. The delivery catheter includes an outer sheath assembly and an inner sheath assembly. The outer sheath assembly includes a capsule in which a prosthetic valve can be received and an outer sheath fixedly connected at one end to the capsule. The inner sheath assembly includes an inner sheath and an anchor fixedly connected to the inner sheath. The inner sheath assembly is arranged within a lumen of the outer sheath assembly, and the capsule and the anchor form a circumferentially indexed fit therebetween. With this design, the anchor and the capsule can be driven to rotate under the action of circumferential rotation of the inner sheath, thus the matching between the prosthetic valve and a native valve annulus can be adjusted. Moreover, the capsule can be driven to move axially under actuation of the outer sheath to allow release of the prosthetic valve.

Abstract: A method of delivering a prosthetic mitral valve includes delivering a distal anchor from a delivery sheath such that the distal anchor self-expands inside a first heart chamber on a first side of the mitral valve annulus, pulling proximally on the distal anchor such that the distal anchor self-aligns within the mitral valve annulus and the distal anchor rests against tissue of the ventricular heart chamber, and delivering a proximal anchor from the delivery sheath to a second heart chamber on a second side of the mitral valve annulus such that the proximal anchor self-expands and moves towards the distal anchor to rest against tissue of the second heart chamber. The self-expansion of the proximal anchor captures tissue of the mitral valve annulus therebetween.
