Intended Use

The Radially Expanding Vascular Access System (Heparin Coated) is intended for use during minimally invasive surgery for temporary percutaneous vascular access for passage of instruments into the vasculature. The device is configured to be used for arterial or venous access. The InnerDyne, Inc., Radially Expanding Vascular Access System (Heparin Coated) is intended to provide percutaneous access to the vasculature. The Radially Expanding Vascular Access System (Heparin Coated) is indicated for the following usages: Percutaneous vascular access.

Device Story

System consists of expandable sleeve assembly, tapered dilator, and sheath with integral hemostasis valve. Operates via Seldinger technique; expandable sleeve inserted over guidewire to dilate tissue; dilator/sheath assembly inserted through sleeve lumen, further expanding sleeve and surrounding tissue. Dilator removed, leaving sleeve and sheath as sealed port for instrument passage. Allows sequential placement of different diameter sheaths. Used in clinical settings by physicians for minimally invasive procedures. Heparin coating applied to sleeve surface to reduce thrombogenicity. Benefits include controlled, sequential vascular access with reduced trauma via radial expansion.

Clinical Evidence

No clinical data. Bench testing only.

Technological Characteristics

Expandable sleeve assembly, tapered dilator, and sheath with integral hemostasis valve. Materials: medical grade, assembled via adhesives, welds, and mechanical interlocks. Surface treatment: heparin coating. Working diameter range: 6-12F. Sterilization: not specified.

Indications for Use

Indicated for percutaneous vascular access in patients requiring temporary arterial or venous access for instrument passage during minimally invasive surgery.

## SUMMARY OF SAFETY & EFFECTIVENESS INFORMATION

InnerDyne, Inc. Submitter: 5060 Amelia Earhart Dr Salt Lake City, Utah (801)-350-3600

Date Prepared: February 13, 1998

Rick Gaykowski Contact: Corporate Vice President, Regulatory Affairs and Ouality Assurance

Classification Name: Percutaneous Introducer Common/Usual Name: Percutaneous Introducer With Sheath Trade/Proprietary Name: InnerDyne Radially Expanding Vascular Access System (Heparin Coated)

The Radially Expanding Vascular Access System (Heparin Coated) consists of an expandable sleeve assembly. The tubular member of the expandable is configured so as to be radially compressed to reduce the outside diameter of the device prior to insertion. Upon use, the expandable sleeve assembly is inserted through the skin and surrounding tissue into the selected ver a previously placed guidewire according to the techniques of Seldinger. (An alternative placement method would have the needle placed within the lumen of the expandable sleeve, and the combined needle and sleeve inserted into the target vessel. The guidewire would be placed and the needle removed.) The dilator/sheath assembly, which consists of a tapered dilator and sheath with integral hemostasis valve, is inserted over the guidewire through the lumen of the expandable sleeve which expands radially to accommodate the dilator/sheath. This process in turn, radially expands the surrounding tissue. Following dilation the dilator is removed, leaving the expandable sleeve and sheath with integral hemostasis valve in place to provide a sealed port for passage of instruments.

This system configuration allows the user to initially place a small diameter sheath for passage of small instruments. The sheath can then be removed from the sleeve while leaving the sleeve inserted in the vessel. A larger diameter dilator/sheath can then be inserted through the sleeve to create a larger port for passage of the larger instruments.

The device is assembled from medical grade materials under GMP and ISO conditions. Components are molded and machined by qualified suppliers. The components are assembled and secured by adhesives, welds, and mechanical interlocks.

The subject InnerDyne, Inc., Radially Expanding Vascular Access System (Heparin Coated) device is substantially equivalent to the predicate InnerDyne, Inc., Radially Expanding Vascular Access System device (K972684). The subject Radially Expanding Vascular Access System (Heparin Coated) device is similar to the referenced predicate in size, function, product dimensions and indications for use.

{1}------------------------------------------------

The Radially Expanding Vascular Access System (Heparin Coated) is intended for use during minimally invasive surgery for temporary percutaneous vascular access for passage of instruments into the vasculature. The device is configured to be used for arterial or venous access.

The basic design principles for the subject InnerDyne, Inc., Radially Expanding Vascular Access System (Heparin Coated) device and the predicate Radially Expanding Vascular Access System device (K972684) are similar, and remain essentially unchanged from information previously provided to the Agency. The product configuration, composition, and utilized materials are similar in each of the products. The principles of operation for the InnerDyne, Inc., Radially Expanding Vascular Access System (Heparin Coated) device, and the predicate Radially Expanding Vascular Access System device (K972684) are similar. That is, each of these products employs a similar insertion technique, indications for use, contraindications for use, warnings and precautions. The subject device differs from the referenced Radially Expanding Vascular Access System predicate (K972684) with the addition of a heparin coating to the surface of the expandable sleeve portion of the device, and an expansion of the sheath working diameter range from (6 - 12F). The inclusion of a heparin coating on an offered product is a common industry practice in distributed devices which come in contact with circulating blood. An example of a substantially equivalent heparin coated device is the Research Medical Pediatric Femoral Arterial Cannula, which contains the DuraFlow II Heparin Coating cleared for marketing under K861641.

From the foregoing, we conclude that the Radially Expanding Vascular Access System (Heparin Coated) device is as safe and effective as currently marketed devices for the stated indications.
