Devices and methods for anatomic mapping for prosthetic implants

A method of generating a patient-specific prosthetic includes receiving anatomic imaging data representative of a portion of a patient's anatomy. A first digital representation of the anatomic imaging data is defined. The first digital representation of the anatomic imaging data is modified. A second digital representation of the portion of the patient's anatomy is defined based on the modifying of the first digital representation of the anatomic imaging data. A patient-specific prosthetic template of the portion of the patient's anatomy is generated based at least in part on the second digital representation of the anatomic imaging data.

09622845 · 2017-04-18 ·

A method and apparatus is provided for creating an internal reconstruction tissue graft. Templates may be used to create a multitude of patterns in a variety of tissue reconstruction grafts. An apparatus may be used to create an internal tissue graft for reconstruction through either compression and/or removal of segments. An apparatus may be used, through either compression and or removal of segments of a preformed template made of synthetics and or metal that mirrors a template that can be used as an internal tissue graft for reconstruction. In a method, such as using software analysis and an apparatus, the physical properties of the tissue graft and its pre- and post-operative properties and appearance may be measured.

09603707 · 2017-03-28 · ·

A mandrel (5) for molding polymer valve leaflets for heart valve prostheses is disclosed, including a body portion (52) including an outer surface with ridges (60) and contoured surfaces (64) corresponding to the leaflets, the upper edge of the contoured surfaces corresponding to the free upper edge of the leaflets, and the mandrel including a mandrel extension (54) above the body portion, and a gap (68) extending around the mandrel between the upper edge of the contoured surface and the mandrel extension. A process for producing these polymer valve leaflets is also disclosed by dip coating with this mandrel and removing the polymer film created at the gap, preferably by applying suction or blowing thereto.

ELECTROSPINNING WITH SACRIFICIAL TEMPLATE FOR PATTERNING FIBROUS CONSTRUCTS

Methods are disclosed which combine electrospinning and a sacrificial template, such as with additive manufacturing (AM), to produce fibrous microvascular scaffolds which are biodegradable, porous, and easily handled. In one example, a process for fabricating a fibrous network construct is disclosed. The method includes electrospinning a first layer of fibrous material; printing a micropatterned sacrificial template; transferring the micropatterned sacrificial template onto the electrospun fibers; electrospinning a second layer of fibrous biomaterial onto the micropatterned sacrificial template thereby encapsulating the template and generating a construct with two layers; and removing the sacrificial template, producing a fibrous construct with channels or microstructures formed therein. Also disclosed are fibrous constructs and scaffolds produced by the provided methods.

TRIMMING APPARATUS

A vascular graft with trim lines is described, the trim lines providing a guide for precision shaping of the cuff. The trim lines may be printed or otherwise disposed on a surface of the cuff or included on a template designed for disposition over the cuff. The trim lines may also be disposed on a side of a pocket into which the cuff is positioned for trimming. Also described is an apparatus and method for precise trimming of a vascular graft.

THREE DIMENSIONAL PRINTING MODALITY COMBINING FUSED DEPOSITION MODELING AND ELECTROSPINNING

Disclosed herein is an apparatus for fabricating a branching structure, the apparatus comprising: a flexible, electrically conductive internal electrical field collector comprising a first collector end, a second collector end, a collector outer surface located between both collector ends, a collector longitudinal axis extending through the first collector end and the second collector end, and at least one articulating feature positioned between the first collector end and the second collector end, a compression and rotation mechanism in contact with the first collector end, and a continuously formed mandrel that can include branches,, having a first mandrel circumference with a mandrel inner circumference larger than the collector outer circumference and positionable over the internal electrical field collector and a second mandrel located at sufficient distance outside the first mandrel to facilitate attraction of electruspun fibers. Also disclosed are methods of manufacturing the branching structure, and grafts thereof.

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.

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.

Systems and methods for manufacturing a stent frame

A prosthetic heart includes a support structure, an actuator member, a plurality of leaflets, and a sealing material. The support structure includes a plurality of struts movably coupled together such that the support structure moves incrementally between a radially compressed state and a radially expanded state. The struts include a plurality of commissure struts. The actuator member is coupled to the struts of the support structure and is configured to incrementally move the support structure between the radially compressed state and the radially expanded state and to automatically lock the support structure in a particular state. The leaflets are coupled to the commissure struts of the support structure and configured to allow unidirectional blood flow through the prosthetic heart valve. The sealing material is coupled to the support structure and includes a plurality of commissure extensions that wrap around and are coupled to the commissure struts of the support structure.

METHODS AND DEVICES FOR ATTACHING OR REATTACHING SOFT TISSUE TO BONE
20170042556 · 2017-02-16 ·

Embodiments of the invention include implants, instruments, and methods for attaching or reattaching soft tissue (200, 2200) to a bone (100), that enable independent tensioning of multiple connectors such as sutures (60, 160, 2060, 2160) and enable redundant fixation between bone (100) and soft tissue (200, 2200). Some embodiments provide for improved accuracy of the placement of substantially parallel tunnels through which soft tissue (200, 2200) to bone (100) connectors such as sutures (60, 160, 2060, 2160) are passed.
