Claims
- 1. A hemostatic sheath in combination with a medical device for accessing a body site within a human patient, said sheath initially disposed in an unapplied position within said device and slidable, relative to said device, to protrude from said device in an applied position and engage the margins of said site, said sheath comprising a hollow, cylindrical plug having a longitudinally extending axis and a longitudinally extending opening along said axis, said plug being arcuate transverse said axis and having circumferentially spaced apart axially extending side edges and means for occluding and preventing the flow of blood from said site when exposed to fluid from said site thereby minimizing complications from bleeding.
- 2. A hemostatic sheath in combination with a medical device for accessing a body site within a human patient, said sheath initially disposed in an unapplied position within said device and slidable, relative to said device, to protrude from said device in an applied position and engage the margins of said site, said sheath comprising a hollow, cylindrical plug having a longitudinally extending opening along its length whereby fluid from said site causes said sheath to occlude said site thereby minimizing complications from bleeding, said sheath including a longitudinally extending axis, said sheath being shaped in the form of a hollow shaped half-moon transverse to said axis.
- 3. The hemostatic sheath of claim 1, wherein said hemostatic sheath is comprised of collagen.
- 4. The hemostatic sheath of claim 1, wherein said hemostatic sheath includes thrombin.
- 5. A hemostatic sheath for use with an axially extending medical device for accessing a site of a body within a human patient, said medical device including means for inserting said sheath at said site and means for causing relative sliding movement between said sheath and said device, said sheath comprising a semi-cylindrical shaped plug having a circumferentially extending exterior cylindrical wall and a circumferentially extending interior cylindrical wall, said walls connected by circumferentially spaced apart side edges and a swellable material for causing said sheath to swell to prevent the flow of blood from said site when exposed to fluid from said site.
- 6. The hemostatic sheath of claim 5, wherein said means for inserting said sheath includes an elongated member, said interior cylindrical wall disposed on said elongated member.
