Splittable introducer sheath with dual-material construction
The granted patent US12042612B2 describes a splittable introducer sheath designed for medical applications. The sheath features a tubular main body made from a first material, which can be either medium-density polyethylene or high-density polyethylene, both of which may be modified with a friction-reducing additive. A distinctive aspect of the sheath is the presence of at least one stripe, formed from a second material that is a thermoplastic elastomer modified with a siloxane additive. This stripe runs the entire length of the main body and allows the sheath to be divided longitudinally along its length. Notably, the main body does not contain any siloxane additive, ensuring a clear distinction between the materials used.
Further specifications of the introducer sheath include the option for two stripes positioned approximately 180 degrees apart, a wall thickness of the stripes that is substantially equal to that of the main body, and a stripe width ranging from about 0.002 inches to about 0.005 inches, with a maximum width of less than 1/16 inch. The second material's Shore A durometer is specified to be between 37 and 53, and the siloxane additive used is characterized as non-leaching. The patent also mentions that the sheath can be specifically designed as a 5 French sheath, indicating its size for particular medical procedures. These features collectively enhance the functionality and usability of the introducer sheath in clinical settings.
