A retrieval catheter operable by a single clinician that will neither displace a deployed stent nor cause undue trauma to the vascular lumen or lesion. The retrieval catheter may be sized to accommodate both a guidewire and a balloon wire. The retrieval catheter is easy to navigate through tortuous passageways and will cross a previously deployed stent or stent-graft easily with minimal risk of snagging on the deployed stent or stent graft. The sheath and dilator are adapted to allow a guidewire or balloon wire to pass through the walls of both and to allow the sheath and dilator to move axially with respect to each other.

A stented valve including a stent structure including a generally tubular body portion having a first end, a second end, an interior area, a longitudinal axis, and a plurality of vertical wires extending generally parallel to the longitudinal axis around a periphery of the body portion, wherein the plurality of vertical wires includes multiple commissure wires and at least one structural wire positioned between adjacent commissure wires, and a plurality of V-shaped wire structures having a first end, a second end, and a peak between the first and second ends, wherein a first end of each V-shaped structure extends from a first vertical wire and a second end of each V-shaped structure extends from a second vertical wire that is adjacent to the first vertical wire, wherein each V-shaped structure is oriented so that its peak is facing in the same direction relative to the first and second ends of the body portion, and a valve structure including a plurality of leaflets attached to the stent structure within the tubular body portion.

Multi-filter endolumenal methods and systems for filtering fluids within the body. In some embodiments a multi-filter blood filtering system captures and removes particulates dislodge or generated during a surgical procedure and circulating in a patient's vasculature. In some embodiments a dual filter system protects the cerebral vasculature during a cardiac valve repair or replacement procedure.

The invention features a glenoid (shoulder socket) implant prosthesis, a humeral implant prosthesis, devices for implanting glenoid and humeral implant prostheses, and less invasive methods of their use for the treatment of an injured or damaged shoulder.

Systems and methods for native heart valve repair includes an anchor. The anchor includes an anchor body configured to transition from a first configuration, in which the anchor body is straightened for transvascular delivery to the native heart valve, to a second configuration comprising at least two turns for implanting at the native heart valve. Two or more of the at least two turns in the second configuration have a diameter smaller than a major axis of the native heart valve.

The invention relates to a glenoid (shoulder socket) implant prosthesis, a humeral implant prosthesis, devices for implanting glenoid and humeral implant prostheses, and less invasive methods of their use for the treatment of an injured or damaged shoulder.

Disclosed herein are gender-specific implantable mesh for inguinal hernia repair in a patient, comprising: a fabric layer comprising a side defining a surface area wherein the fabric layer is configured to enable tissue adhesion to said mesh; an anti-adhesive barrier comprising a shape configured to prevent direct contact between the fabric layer and both a spermatic cord and a genital nerve upon implantation, wherein the shape covers a part of the surface area on the side of the fabric layer, the part being less than 25%, and wherein the shape is oblique to a horizontally-oriented centerline and a vertically-oriented centerline; and a keyhole configured to fit the genital nerve and the spermatic cord of the patient therethrough without constriction, wherein the keyhole is oblique and inferior to a horizontally-oriented centerline and medial to a vertically-oriented centerline.

Medical device for breast reconstruction for containing or integrating a breast implant, the device being designed for placement between the skin and the pectoralis major muscle and is configured to be sutured to the pectoralis major muscle. The device includes a container body having a half shell and a flat appendage joined continuously to a portion of the base of the half shell.

A method of removing embolic material from a vessel with mechanical and aspiration assistance. The method comprises the steps of providing an aspiration catheter having a central lumen and a distal end, advancing the distal end of the aspiration catheter to obstructive material in a vessel, applying vacuum to the central lumen to draw clot into the central lumen, introducing a thrombus engagement tool into the central lumen, and manually manipulating the tip to engage clot between the tip and an inside wall of the central lumen.

A heart valve anchor apparatus may include a body having a proximal portion and a distal portion. The body may include a first radially expandable portion at the proximal portion of the body, a second radially expandable portion at the distal portion of the body, and a root portion extending from the first radially expandable portion to the second radially expandable portion, the root portion having an outer extent. The first radially expandable portion may be configured to self-expand to an outer extent greater than the outer extent of the root portion when radially unconstrained. The second radially expandable portion may be configured to self-expand to an outer extent greater than the outer extent of the root portion when radially unconstrained. In an unstressed configuration, the body may define a longitudinal centerline that extends away from a plane tangent to the root portion.
