LANDING ZONE FOR ENDOVASCULAR PROCEDURES
20220401238 · 2022-12-22 ·

Systems and methods for building a landing zone for an endovascular procedure are described. This procedure is “hybrid” in that it involves both direct access (e.g., sternotomy or partial sternotomy) to the site for installation of the landing zone, as well as endovascular installation of a TAVR or TEVAR device (e.g., stent graft) once the landing zone is installed. The landing zone is installed by wrapping a landing band around a portion of a vessel. The landing band may be selected to be fixed at a diameter so that it inhibits any expansion of the vessel, and also supports a later-installed TAVR or TEVAR device. The TAVR or TEVAR device is then endovascularly delivered to the vessel and deployed therein. The device expands until it contacts the vessel, which is supported from the outside by the landing band, which thus constrains and supports the device from outside.

Surgery for correcting tricuspid valve regurgitation

A method is presented for tricuspid valve commissural annuloplasty for secondary tricuspid insufficiency. The method comprises suturing through a valve annulus, and bringing the valve annulus to its normal size while eliminating its regurgitation. The suturing comprises applying individual sutures on pledgets through the tricuspid valve annulus from a right ventricle side along anteroposterior and posteroseptal commissures on both sides of each of said commissures, spaced-apart from them; taking out needles of said sutures from a right atrium side and tying knots along the commissures between them.

Stent

The invention relates to a medical device and a method of using it. The device is a stent which can be percutaneously deliverable with (or on) an endovascular catheter or via other surgical or other techniques and then expanded. The stent is configured to have a central portion defined by “open” cells and at least two end portions, defined by “closed” cells, spaced apart and directly connected to the distal and proximal ends of the central portion of the stent. The stent may also optionally have a covering or a lattice with openings.

PROSTHETIC HEART VALVE

A prosthetic heart valve comprises an annular frame that is radially compressible and expandable between a radially compressed state and a radially expanded state, wherein the frame elongates in an axial direction when radially compressed from the radially expanded state to the radially compressed state. Leaflets are coupled to the frame such that when the frame is in the radially expanded state, the leaflets have slack in an axial direction, wherein when the frame is radially compressed to a partially radially compressed state between the radially expanded state and the radially compressed state, the leaflets are in a relaxed state, and wherein when the frame is in the radially compressed state, the leaflets are stretched in the axial direction.

Method of treating prolapse of a vagina

A method of treating prolapse of a vagina includes supporting the vagina by implanting a sacrocolpopexy support and locating an exterior surface of the vagina between leg portions of a vaginal cuff section of the support, and securing a head section of the support to a ligament or a sacrum while isolating the head section from contact with tissue of the vagina.

Graft preparation system

A graft preparation system includes a fixation implant including a strand of suture wrapped around a graft preparation card. A tenaculum includes a first arm having a first tooth and a second arm having a second tooth that are pivotally connected at a pivot. The first arm includes a slot between the first tooth and the pivot that receives the graft preparation card. A tape suture assembly includes a tape suture and a first suture strand. The tape suture is positioned on a graft, and the tape suture is attached to the graft with a stitch formed with the first suture strand.

IMPLANTABLE VEIN FRAME
20220378576 · 2022-12-01 ·

An implantable vein frame is contemplated in which two ring members are rigidly joined in spaced axial alignment via one or more interconnecting members. One of the one or more interconnecting members defines a protruding region that acts upon the implant placed within the frame and/or the vein that the vein frame is placed within to define a sinus region. The implant is placed within and scaffolded by the vein frame, and the vein frame is subsequently inserted within a vein via a venotomy, or interposed between two vein segments via vein interposition graft. The vein frame acts to support the structural integrity of the implant, and to scaffold and anchor the implant in place with the vein.

URETERAL STENT
20220378567 · 2022-12-01 ·

In some examples, a medical system including a stent configured to be positioned within a ureter of a patient. The stent includes one or more distal petals and/or one or more proximal petals resiliently biased to deploy radially outwards from a stent body. The stent may be configured to position the distal petals in a kidney of a patient and position the proximal petals in a bladder of the patient. The distal petals and/or proximal petals may be configured to resist a migration of the stent within the ureter. The stent may include suture configured to cause the distal petals and/or proximal petals to substantially to collapse for withdrawal of the stent. The medical system may include a sheath to retain the distal petals and/or proximal petals in a collapsed condition during, for example, implantation in the patient.

Charged grafts and methods for using them

A system for preventing thrombosis in an implantable medical device includes an implantable medical device sized for implantation at least partially within a patient's body. The device includes an at least partially electrically conductive portion that is disposed within a patient's body upon implantation, an electrode coupled to the electrically conductive portion of the device; and a power source coupled to the electrode. The power source provides a negative electric charge to the at least partially electrically conductive portion for an indefinite period of time. The device may be configured to resist thrombosis, infection, and/or undesired tissue growth via the charged conductive portion once implanted. Exemplary embodiments of the implantable medical device include a hemodialysis vasculature graft, a dialysis catheter, a coronary artery, and a heart valve.
