Apparatuses and methods for use in surgical vascular anastomotic procedures
Apparatuses and methods for use in surgical vascular anastomotic procedures. Apparatus includes a blood vessel inner wall (BVIW) sealing and hole forming device, and a hole forming actuator. BVIW sealing and hole forming device includes a hole sealing device, and an anastomotic hole generating device. Hole sealing device includes a sheath that fully encloses and holds a self-expanding hole sealing assembly, a manual hole sealing controller assembly, and a flexible control wire enclosed within a flexible tube. Anastomotic hole generating device includes outer and inner assemblies, with a conically shaped anastomotic hole generating member. Hole forming actuator includes outer and inner assemblies. Also disclosed are procedures for performing surgical vascular anastomosis using the disclosed apparatuses and methods. Particularly applicable for use in clampless types of (end-to-side) surgical vascular anastomotic procedures, for performing coronary artery bypass grafting (CABG).

Occluder
Transcatheter heart valve delivery systems having a tip assembly configured to close the hole or perforation made in a patient's septal wall after transseptal delivery of a stented prosthetic heart valve to a defective heart valve (e.g., a mitral valve). The delivery device is configured to permit in vivo release of the tip assembly immediately after deployment of the stented prosthetic heart valve to implant the tip assembly into the septal wall proximate the hole through which the stented prosthetic heart valve is delivered. Methods of treating the defective heart valve, including closing the hole made during transseptal delivery of the stented prosthetic heart valve with the tip assembly of the delivery device are also disclosed.
Gastrocutaneous closure device
A gastrocutaneous closure device allows gastrocutaneous fistula closure from external abdominal access through the fistula site. Access through the fistula ensures accurate closure placement on the interior lumen wall of the stomach. A closure or clip has a plurality of prongs defined by a deformable material, such that the prongs extend radially from a central hub in an arcuate or curved, semicircular shape. The arcuate shape converges towards a central point or axis at a distal end, and the proximate end of the prongs attaches to the central hub such that the prongs radiate from the hub and the distal end curves back toward the axis through the hub. The deformable prongs may therefore radially compress or retract to define a larger or smaller diameter. The fistula lies on the axis such that the biased, inserted prongs pull the inner stomach wall closed around the healing fistula.
Shape-memory polymer foam device for treating aneurysms
A system for treating an aneurysm in a blood vessel or vein, wherein the aneurysm has a dome, an interior, and a neck. The system includes a shape memory polymer foam in the interior of the aneurysm between the dome and the neck. The shape memory polymer foam has pores that include a first multiplicity of pores having a first pore size and a second multiplicity of pores having a second pore size. The second pore size is larger than said first pore size. The first multiplicity of pores are located in the neck of the aneurysm. The second multiplicity of pores are located in the dome of the aneurysm.
Implantable sealable member with mesh layer
The provided technologies provide an implant closure device having a mesh layer formed on a flexible substrate, collectively forming a sealable member, that improves a seal formed over an aperture in a body lumen. The mesh facilitates a faster and more secure adherence of the sealable member to the surrounding edges at the puncture site. Furthermore, the provided technology may promote platelet-capture and encourage localized platelet aggregation at the exposed collagen in the wound edges on the mesh layer. The platelet impregnated mesh layer can facilitate cellular adhesion, enabling the sealable member that is local to the wound opening to act, in essence, as a “biological glue.”
SHEET-SHAPED OBJECT ATTACHING DEVICE
A device for efficiently attaching a sheet-shaped object to a target site includes a support body for supporting a sheet-shaped object, and a protective member having a low coefficient of friction for protecting one surface of the support, in which the support body supporting the sheet-shaped object is rolled while being protected by the protective member and can be inserted into a tubular body.
Hematostick/HematoDart
The present disclosure provides hemostatic agent applicators configured to deliver hemostatic agents to an internal or external bleeding surface for promoting the clotting of blood, and to methods of using the applicator, and to kits comprising the applicator.
Temporary anastomotic seal and method
Forming a proximal anastomosis on an aortic wall includes method and instrumentation and apparatus for forming an aortic puncture and inserting into the vessel through the puncture a fluid-impervious sealing element with a protruding retainer. An anastomosis of a graft vessel over the puncture is partially completed with the retainer of the sealing element protruding through the partial anastomosis. The retainer facilitates removal of the sealing element from the partial anastomosis prior to completion of the procedure.
Suturing devices and methods for suturing an anatomic structure
Suturing devices and systems used to close openings into a biological structure. The suturing device can comprise an elongate member having a proximal end, a distal end, one or more arms, and one or more needles. One or more sheaths may be used with the device to maintain or substantially maintain haemostasis while the device is used and while a procedure is performed in the biological structure.
