SYSTEMS AND METHODS FOR MAKING ENCAPSULATED HOURGLASS SHAPED STENTS
Systems and methods for the manufacture of an hourglass shaped stent-graft assembly having an hourglass shaped stent, graft layers, and an assembly mandrel having an hourglass shaped mandrel portion. Hourglass shaped stent may have superelastic and self-expanding properties. Hourglass shaped stent may be encapsulated using hourglass shaped mandrel assembly coupled to a dilation mandrel used for depositing graft layers upon hourglass shaped mandrel assembly. Hourglass shaped mandrel assembly may have removably coupled conical portions. The stent-graft assembly may be compressed and heated to form a monolithic layer of biocompatible material. Encapsulated hourglass shaped stents may be used to treat subjects suffering from heart failure by implanting the encapsulated stent securely in the atrial septum to allow blood flow from the left atrium to the right atrium when blood pressure in the left atrium exceeds that on the right atrium. The encapsulated stents may also be used to treat pulmonary hypertension.
Mitral valve spacer device
An implantable prosthetic spacer device can include an inflatable spacer having a plurality of inflatable members and a frame, the frame comprising one or more anchors and one or more clasps. The inflatable spacer can be configured to be disposed between native leaflets of a heart. The implantable prosthetic spacer can be disposed in a symmetrical or an asymmetrical configuration. The inflatable spacers can be inflatable between an uninflated and an inflated configuration.
PANCREATIC STENT WITH DRAINAGE FEATURE
A pancreatic stent includes a main body convertible between a compressed configuration for delivery and an expanded configuration once deployed, the main body including an inner surface defining a stent lumen and an outer surface. A plurality of drainage features are formed within the outer surface of the main body, the plurality of drainage features permitting placement of the pancreatic stent within a patient's pancreas without blocking side branches of the pancreas.
FULL CONTOUR BREAST IMPLANT
Full contour absorbable implants for breast surgery redistribute breast volume between the breast's upper and lower poles in exact and desirable ratios. The implants preferably redistribute breast volume so that the upper pole breast volume is 20-40% of the total volume, and the lower pole breast volume is 60-80% of the total volume. The implants are also designed to provide specific curvatures to the poles of the breast, and to angulate the nipple areolar complex slightly skyward so that the patient's nipple is positioned at an angle above the nipple meridian reference line. The implants are designed to be transitory, with sufficient strength retention to allow transition from support of the breast by the implant to support by regenerated host tissue growing in and around the implants, without any significant loss of support during or subsequent to remodeling. The implants may optionally be used with permanent breast implants.

METHOD OF FACILITATING NERVE GROWTH
Disclosed are methods, devices and materials for the in situ formation of a nerve cap and/or a nerve wrap to inhibit neuroma formation following planned or traumatic nerve injury. The method includes the steps of identifying a severed end of a nerve, and positioning the severed end into a cavity defined by a form. A transformable media is introduced into the form cavity to surround the severed end. The media is permitted to undergo a transformation from a first, relatively flowable state to a second, relatively non flowable state to form a protective barrier surrounding the severed end. The media may be a hydrogel, and the transformation may produce a synthetic crosslinked hydrogel protective barrier. The media may include at least one anti-regeneration agent to inhibit nerve regrowth

Device for Heart Repair
Disclosed herein is a catheter device (2) for implanting a leaflet anchor (10) and a papillary anchor (9) into the heart as part of a procedure for implanting an artificial chordae line (14) that extends between the leaflet anchor (10) and the papillary anchor (9), the catheter device (2) comprising: a two-part housing section extending from a distal end (8) of the catheter device (2) along the length of the catheter device (2) toward the proximal end (4) of the catheter device (2), the two-part housing section being arranged to be placed between the papillary muscle and a leaflet (12) of the heart during use of the catheter device (2), and the two-part housing section comprising a distal part (8) at the distal end of the catheter device (2) and a proximal part (4) located on the proximal side of the distal part (8); a leaflet anchor deployment mechanism at the proximal part (4) of the housing section for deploying a leaflet anchor (10) for attachment to the leaflet (12) of the heart; a papillary anchor deployment mechanism at the distal part (8) of the housing section for deployment of a papillary anchor (9) for attachment to the papillary muscle, wherein the papillary anchor deployment mechanism is arranged for deployment of the papillary anchor (9) by moving it outward in the distal direction relative to the distal part (4); and a flexible joint (34) located between the proximal part (4) and the distal part (8) of the two-part housing section, wherein the flexible joint (34) allows a centreline of the distal part (8) to be angled relative to a centreline of the proximal part (4).

Device for Heart Repair
Disclosed herein is an anchor system for implantation in body tissue to hold a line (18). The anchor system comprises an anchor (9), the anchor (9) comprising a number of hooks (62) for engagement with the body tissue and having a folded configuration and an unfolded configuration. The anchor (9) is made of an elastic material such that it can be elastically deformed into the folded configuration by application of a constraining force, and will return to the unfolded configuration when no constraining force is applied. The end of each of the hooks (62) comprises a tip (160′), wherein the tips (160′) are formed to curve towards a central axis of the anchor (9) when the anchor (9) is in the folded configuration.
